    Opis:
    The strength and temporal rigidity of climate signals are important characteristics of proxy data used to reconstruct climate variability over pre-instrumental periods. Here, we assess the performance of different tree-ring proxies, including ring width, maximum latewood density, δ13C, and δ18O, during exceptional cold (1800–1850) and warm periods (1946–2000). The analysis was conducted at a spruce (Picea abies) timberline site in the Swiss Alps in proximity to long homogenized instrumental records to support calibration tests against early temperature and precipitation data. In this cold environment, tree-ring width, maximum latewood density, and δ18O are mainly controlled by temperature variations. δ13C is influenced by various factors including temperature, precipitation, sunshine, and relative humidity. When comparing the response patterns during cold and warm periods, ring width and maximum latewood density revealed temporally stable temperature signals. In contrast, the association between the stable isotopes and climate changed considerably between the early 19th and late 20th centuries. The temperature signal in δ18O was stronger during the recent warm period, whereas the opposite is true for δ13C. In δ13C, the temperature signal weakened from the early 19th to the late 20th centuries, but an (inverse) precipitation signal evolved indicating that soil moisture conditions additionally limited recent carbon isotope ratios. An attempt to combine the tree-ring proxies in a multiple regression model did not substantially improve the strength of the dominating temperature signal retained in the latewood density data as this proxy already explained a significant fraction of summer temperature variability. Our findings underscore the importance of split calibration/verification approaches including cold and warm periods, and challenge transfer models based on only late 20th century observational data.

    Opis:
    Geomorphological events are very important disturbance factors for cliff forests and forests located on steep mountain slopes. In this study we present dendrochronological reconstruction of two types of disturbances which affect subalpine forest growing in such extreme habitats in Roztoka Valley in the Tatra Mountains: landslide and rockfalls. We determine the years of death of trees found in landslide area on Czuba Roztocka which indicate the year of 1997 as the time of this event, probably related to heavy midsummer rainfall in this year. Scars on trees growing at the base of Orle Ściany cliff allowed determining the rockfall events. We found that scars, even in neighbour trees were formed in different years between 1940 and 2004. It means that they were formed rather by separate stones which fell from the cliff sporadically then a large scale fall of debris at the same time. This may suggest that rockfalls in cliffs of Orle Ściany were limited to single rocks which fell successively when erosion process separated them from the bedrock. Dendrochronology seems to be an effective method which enables long term reconstruction of gemorphological processes in the High Tatras.

    Opis:
    We have compared maps of landslide activity and hazard, developed with the use of two different dendrochronological indicators: tree-ring eccentricity and reaction (compression) wood. The maps were prepared based on 125 Norway spruce (Picea abies L. Karst.) trees growing at 44 sampling points, distributed over an area of 3.75 km2. In general, the two maps show similar patterns of landslide activity. However, tree-ring eccentricity yielded a greater number of dated events (246) compared to compression wood (129). Besides the differences in the absolute values of dating results, the general landslide activity and hazard zonation based on both disturbances are similar. Both growth disturbances develop as a result of stem tilting. Eccentricity develops after slight tilting, while compression wood is developed when tilting is more significant. Because of the differences in the strength of disturbing factors, which cause the development of compression wood and growth eccentricity, the best approach would be to combine the results of dating obtained from the two methods. The dendrochronological analysis of tree growth disturbances (eccentric growth and compression wood) is a promising approach for determining landslide hazards in forested mountain areas and can be applied in spatial management.

    Opis:
    In this study, an Estonian tree-ring network of Norway spruce (Picea abies (L.) H.Karst.), originating from both living trees and dead wood of construction wood, was used for determining the growth variations over the past 350 years (AD 1657–2009). Regional curve standardization was used to remove the non-climatic growth variations from the individual tree-ring series prior to dendroclimatic analyses to focus on the low-frequency (long-term and -period) growth variations. Previously, the chronology has been shown to correlate markedly well with Estonian precipitation history. Here we further detail this dendroclimatic connection. Correlations between the Estonian precipitation and treerings improved systematically with both the number of meteorological stations included and with the documented technical advances in the network of instrumental weather observations. The observed June precipiation explains roughly 20 percent of the tree-ring variance over the period when the network of weather observations is densest (1946–2009). On decadal and longer scales, the June precipitation explains higher portion of tree-ring variance, roughly 50 percent, over the full instrumental era (1866–2009). Comparison with previously published and similarly standardized tree-ring chronology from south-eastern Finland, based on Scots pine tree-rings, showed that the two chronologies exhibit several coinciding periods of ameliorated and deteriorated growth.

    Opis:
    Pinus sylvestris L. (Scots pine) is the main forest tree species in Burabai National Park. Trees here grow under continental climate conditions. There are no dendroclimatological studies based on Scots pine of this region. The purpose of this study was to find the relationships between tree-ring widths and climate. For this purpose, a total of 176 cores from 100 Scots pine trees were collected. After measuring tree-ring widths, standard chronology building methods were used, and three site chronologies were constructed. Correlation coefficients between tree-ring widths with temperature and precipitation were calculated. Precipitation from October of the previous year to July of current year had a positive influence on tree-ring widths and August–September precipitation have the opposite effect. Temperature in the winter had positive effect for tree-ring growth but significantly negative during summer. Effects of climate changes on tree-ring widths were observed. The variation and sensitivity of tree-ring widths increased after 1940s. An increasing trend in precipitation, temperature, and tree-ring widths were clearly observed. In conclusion, tree-rings of Scots pine in Burabai are highly sensitive to growing site conditions and are affected by climate changes.

    Opis:
    Juniper is one of the three main tree species in Central Anatolia, where it grows under extreme environmental conditions. Although dendrochronological studies of juniper are challenging because of cross-dating problems, these types of studies on long-lived tree species have the potential to provide long time series, which reflect changes in climatic conditions. Juniper has been neglected as a scientific research subject in Turkey due to degraded populations and low economic expectations. This study analysed the distribution and present state of Juniperus spp. (Juniperus excelsa M. Bieb., Juniperus oxycedrus L., and Juniperus foetidissima Willd.) stands and used dendrochronological data to examine relationships between growth and environmental parameters. We hypothesised that there may be differences in the radial growth of juniper in areas of different exposure in drought regions. During a field survey, we sampled 31 plots of 25 m × 20 m and data, including information on wood cores, were collected. For dendrochronological investigation, 95 wood cores were manually measured and cross-dated. Residual chronologies of tree-ring width series of juniper from four wind directions and regional chronology of Kirikkale and Ankara Province were provided and similarities between the chronologies were tested using Gleichläufigkeits test. The relationships be- tween climate parameters and growth were examined using a simple correlation analysis and multiple lin- ear regression model analysis in SAS 9.0 program and response function analysis in the DENROCLIM2002 program. The results of this study indicated that Juniperus spp. in Central Anatolia are sensitive to envi- ronmental parameters and mainly respond to changes in precipitation. Juniper show differences in radial growth in areas of different exposure in drought regions. We conclude that juniper may offer an excellent opportunity for large-scale dendrochronological and dendroecological studies in drought regions.

    Opis:
    The aim of the study was to evaluate the sensitivity of silver fir (Abies alba Mill.) from the Rudnik Forest District on the selected meteorological elements and to develop a chronology of local tree-ring width and the annual sensitivity. Based on the analysis, the site chronology of silver fir was developed and the strength of the relationship between the climate components and the width of annual rings was calculated. In addition, we examined the degree of homogeneity of short-term incremental response, rated the representativeness of the chronology and climate signal strength. Having analysed the indicator years, namely 1932–2013, we concluded that the growth of firs was positively influenced mainly by air temperature in winter, and to a lesser extent, by precipitation in spring and summer. The main factors that limit its growth are cold winters, cool and low rainfall summers, and rainy springs.

    Opis:
    Szczecin harbours Poland’s largest London plane tree population. The London plane trees growing in Szczecin’s Żeromski Park were subjected to dendroclimatological research (analyses of signature years and response function). The study was based on a composite site chronology, signed ZER, spanning 105 years (1900–2004); the mean annual tree ring growth was 2.59 mm. Precipitation, particularly that in late winter- early spring and in the summer months was found to be a factor decisive for the tree’s cambial activity. A high sum of precipitation during the periods mentioned induced positive growth responses in the trees. Thermal conditions during the growth period proved to be another factor controlling the annual tree ring growth, as shown by linear relationships. The tree ring growth-climate relationships in the population under study as well as the between-parks differences in the London plane tree response can be explained by differences in habitat conditions. The trees under study grow in the vicinity of a busy, frequently repaired street and are surrounded by pavement and/or hardened road surface, which greatly limits the infiltration of moisture supplied by precipitation.

    Opis:
    Forested mountain slopes can be simultaneously affected by soil creep and landslide activity, both of which cause the tilting of tree stems, with the result that their dendrochronological record of tree-ring eccentricity and compression wood is potentially similar. There is a need to identify similarities and differences in these records and thus our research aimed to compare patterns of eccentricity and compression wood developed by trees under the impact of soil creep and landslides. We sampled trees growing on a landslide and creeping slopes in the Kamienne Mts., with 21 Norway spruce trees were sampled on each site. We found several main differences between the dendrochronological record of landslide activity and soil creep. On the landslide we found larger number of dendrochronological events, stronger and more variable eccentricity and a similar number of upslope and downslope events. On creeping slopes, upslope eccentricity events predominate, and the number of eccentricity events dated in all trees increases in time. We also compared the utility of eccentricity and compression wood for dating mass movements. They differ in their sensitivity to stem tilting. Thus, in analyses of landslide activity and soil creep activity, it is recommended to include both wood anatomy features.

    The air temperatures recorded at Warsaw-Okęcie in 1951-2010 were compared with forecasts for the period 1980-2010 and 1991-2010, i.e. 31 and 20 years ahead. Accurate predictions of air temperatures in Warsaw in 1980-2010 were calculated using the cycles identified by applying the sinusoidal regression method to a series of monitoring results obtained in Warsaw between 1779 and 1979. The high accuracy of these forecasts is the result of a similar progression of measured and forecast values over a number of years. The prediction of climate change in the Northern Hemisphere for example, caused by interference of long solar radiation cycles as well as variations in the concentrations of the δ18O oxygen isotope in the Arctic ice cores, requires a larger series of data points.

    Opis:
    This study assessed changes in air temperature and rainfall during the growth of black locusts (Robinia pseudoacacia L.) in urban conditions in the city of Wroclaw based on pointer years. Materials consisted of 54 wooden discs taken from felled straight-trunked trees at a height of 1.3 m from the ground at four sampling sites in the area of a defunct garden established at the turn of the 20th century. Meteorological indicators were calculated based on monthly data obtained from the Wroclaw meteorological station, part of the national atmospheric monitoring network. Tree ring widths were determined using LINTABTM 6 and TSAP-Win software. A set of meteorological elements describing temperature and rainfall conditions during the growth of the black locusts significantly affecting the tree ring widths, were selected using cluster analysis. Pointer years were defined as the years when a unidirectional change (e.g. an increase) in tree ring width compared to a previous year was observed in at least 75% of the trees. In the multiannual period 1955–2014 we found seven pointer years, comprising three positive years (tree ring wider than in the year before): 1986, 1989, 1996, and four negative years (tree ring narrower than in the year before): 1963, 1983, 1990, 1991. The width of the tree rings were formed under the influence of different unique thermal and rainfall systems each year. Within the groups of positive and negative pointer years, individual months differed in the impact of air temperature and rainfall conditions on tree ring widths.

    Opis:
    The aim of the study was to determine the influence of stand density index on the tree−ring width, latewood proportion and wood density for Norway spruce. Study sites were located as follows: 12 within the north−eastern species range in Poland, 7 in the south−western range, in the Sudety Mts., and 9 in the Carpathians (southern range). Clustering stands according to their stand density index, 10 data groups were established: stand density index values from 0.3 to 1.2. The study plots were 100×100 m squares. On each plot 15 trees were chosen and increment cores were sampled using the Pressler borer. The smoothed cores served for measuring the width of annual rings, latewood zones and the share of latewood as well as for determination of relative wood density. The performed analyses indicate that mean tree−ring width was the highest in trees from stands with density index from 0.3 to 0.8 (with the exception of 0.7), whereas the it was gradually decreasing in stands with index higher than 0.9. The statistically significant differences between the analyzed stands were observed (p<0.0001). The analysis of the influence of stand density index and the width of annual rings revealed significant, negative weak correlation (r=–0.242, p<0.001). In turn, the latewood proportion was the highest in trees from stands characterised by the highest stand density index and the lowest in trees from stands with the lowest one. The differences between analyzed groups of stands were statistically significant (p<0.0001), as well as the correlation which was significant, positive and weak (r=0.269, p<0.001). Wood density was the highest in trees from stands with the highest stand density index (1.1 – 363 kg/m3 i 1.2 – 365 kg/m3) as well as in those from stands characterised by 0.7 density index (369 kg/m3). Significant differences were observed (p<0.0001) only between stand density index 0.3−0.7 and 0.7−0.8. Significant correlation was not observed.

    Opis:
    Climate change has a significant impact on natural ecosystems, particularly on floodplain forests that are among the most transformed ecosystems in the world. The climate sensitivity of dominant species is likely to play a key role in determining the susceptibility of flooded forests to climate changes. Here, we use dendrochronological approaches and local climate records from 1880 to 2015 to assess the response in pedunculate oak (Quercus robur L.) trees growing in a floodplain of the Dnipro River near Kyiv to climatic variables. Correlation analysis reveals the strongest positive association of the Q. robur tree-ring width chronology with May–June precipitation, May–June temperature, and May self-calibrating Palmers drought severity indices (scPDSI). The moving-window correlation analysis points to positive association with the scPDSI after the 1950s, when local river regulation was implemented. The positive correlation with current March precipitation is the least expected change in the oak growth-to-climate relationship that occurred in the aftermath of human alterations in the local river and regional climate changes. This study discusses the probable ecological consequences and ecophysiological mechanisms of observable climate-to-growth relationships and their temporal stability.

    Opis:
    Climatic parameters are the main environmental factors affecting tree growth. The main aim of the presented study was to determine whether different oak species growing under contrasting environmental conditions show different sensitivity to climatic parameters. Four oak stands with Quercus robur, Quercus petraea, Quercus polycarpa and Quercus dalechampii growing in the same area were evaluated. Standard dendrochronological methods were used for sample preparation, ring width measurements, cross-dating, chronology development, and the assessment of growth-climate response patterns. Although the species grew under different environmental conditions, their local tree-ring chronologies are highly correlated. The radial growth responses to climatic parameters differ slightly, but the response depends more on local site conditions than on the oak species. At the same time, the strongest correlations between radial growth and climatic parameters were identical among species and sites. The amount of water available in the soil was the main climate-dependent factor limiting radial growth. Approximately since the 1990s, the distribution of rainfalls within the growing season has changed at the expense of spring precipitation. The significance of relative soil moisture content during spring for oak growth increased and the significance of summer values decreased.

    Opis:
    Negative climatic extremes occur more frequently in the last decades. Since the Carpathian Basin is highly concerned in their impacts it is important to investigate prior events and estimate the response of the environment to them to get useful information for the future. In our work we selected a stand which is seriously affected by unfavorable summer conditions to examine what kind of fingerprint the negative extreme events have left. We investigated narrow rings and intra-annual density fluctuation to describe years with extreme events. Their stabilized frequency was tested against climatic and groundwater data, as well as against aridity index to determine climate-growth relationships using Pearson and Spearman’s correlations. Our results show positive significant correspondence between summer precipitation and treering growth together with negative connection with summer temperature. The Spearman’s correlation between stabilized frequency of intra-annual density fluctuations, narrow rings and climate data ended with significant relationship in summer. According to the comparison of intra-annual density fluctuation and narrow ring data with drought periods it can be said that narrow rings are better tool for the examination of negative extreme events in summer.

    Opis:
    Sycamore maple (Acer pseudoplatanus L.) is a fast-growing tree species that produces economically attractive timber, provides ecological services and has high site adaptability, but it is only a minor component of European forests. This paper describes production, structure and diversity of sycamore-dominated forest stands that originated by succession on former agricultural lands in the Orlické hory Mts., the Czech Republic. The partial objectives were to determine impact of climatic factors on the radial growth of sycamore maple and evaluate the effect of game on natural regeneration. The number of sycamore seeds on the ground was on average 9–34 seeds m–2 and seedling mortality reached on average 89% caused by damage of hare and drought. Density of natural regeneration ranged from 1,532 to 4,244 recruits ha–1, but growth dynamic was strongly influenced by ungulate browsing (69%) with the largest losses in sycamore (96%). Analyses of climatic effects showed a significantly close relationship with growth of sycamore in submontane areas, being especially sensitive to extremely dry and cold winters or very high summer temperatures. Radial growth was more significantly influenced by monthly temperatures compared to precipitation, but increasing sum of annual precipitation was main positive driver factor of diameter increment. Radial growth had the strongest relationship with weather conditions in July and October of previous year and March of the current year. Stand volume ranged from 378 to 545 m3 ha–1 at age around 75 years, while sycamore accounted for 32–82%. The horizontal structure of the tree layer was mostly random to aggregated; resembling the clumped spatial pattern of natural regeneration. Besides their wood production, these stands fulfil many ecosystem functions that are associated with high ecological stability, high structural differentiation and medium to high species diversity.

    Opis:
    The main objective of the study was to evaluate inter-annual ring-width variation and cumulative growth of aspen (Populus tremula L.) trees growing on the spots of different soil CO2 concentration at natural mofette site. We hypothesized that growth rate of trees is affected by CO2 concentration within their rooting zone. The study site was situated in the flood plain of Plesná stream near Hartoušov (Western Bohemia). Trees growing in a pure aspen stand were selected according to the CO2-gas regime within their rooting zone. Five high [CO2] trees (10–25% CO2 in the soil) and five low [CO2] trees (up to 3% CO2 in the soil) were sampled. Stem growth analysis of each trunk was carried out to study growth pattern in detail. High and low [CO2] trees significantly differed in a growth rate. At the age of 25 years, the basal area of high [CO2] trees exceeded low [CO2] trees by 39 %. The positive effect of CO2 on annual increment was pronounced particularly in the years with optimal growing conditions. Results suggest that trees can be fertilized not only by elevated atmospheric CO2 but also when fed with CO2 via the roots.

    Opis:
    In the central part of the Bolshoy Solovetsky Island, in the same type of growing conditions, two plots were created in 1988: the first consisted of twisted pine (Pinus contorta Loud. var. latifolia S. Wats) crops and the second one was of Scots pine (Pinus sylvestris L.). The aim of the study was to establish the morphological parameters of the twisted pine and its growth in the conditions of the Bolshoy Solovetsky Island in comparison with the native species P. sylvestris L. Also, we aimed to identify the features of P. contorta var. latifolia and determine the possibility and necessity of further introduction of the species. The preservation of the twisted pine and scots pine cultures was determined. Accounting trees were selected (62 and 31 trees, respectively), in which morphometric indicators were measured. Wood samples (cores) were taken from them with an age drill to measure radial growth. The radial increment was measured using the MBS-9 microscope and the Lintab device. To measure the increase in height, six medium-sized model trees were cut down. According to the taxation indicators, the two types differed slightly and the differences were most often unreliable. The average height of the twisted pine trees was significantly higher compared to that of Scots pine. The thickness of the bark varied; on average, at the age of 18, it was 1.35 ± 0.038 mm for twisted pine and 1.86 ± 0.095 for Scots pine, that is, the native pine bark was 38% thicker. Typical for twisted pine were a significant number of pathologies noted in 22% of the studied trees. Twisted pine was distinguished by a stronger development of the assimilation apparatus: the number of branches of the first order, the number of branches in the whorl, the life span of needles. An increase in radius (the width of the annual ring) was observed at 14–15 years, and then with age, the value decreased in twisted pine and remained at a consistently high level in Scots pine. The width of the late zone of the annual ring was 12% in Scots pine and 14% in twisted pine; but at a young age, the late wood in twisted pine was very small. The increase in height of the twisted pine was on average less than that of Scots pine. The dependence of the trunk volume on the diameter was almost identical in both species.

    Opis:
    The aims of the study were to determine the effect of temperatures and precipitation on the ring width and to compare the results with the results of previous studies conducted in other mountain ranges of the Czech Republic. The research was performed in the central part of the Ceskomoravská Upland in the vicinity of Herálec municipality in selected 70- up to 110-year-old spruce stands at altitudes from 680ma.s.l. to 779 m a.s.l. Measuring of tree-ring widths and synchronization of individual ring series were conducted in PAST4. The age trend was removed by ARSTAN and climatic effects were modelled in DendroClim2002. The correlation of tree-ring width with monthly precipitation is positive and statistically significant for July of the previous year and for the entire summer period from June to September of the current year. The correlation of tree-ring width with mean monthly temperatures is negative and statistically significant for July and September and positive and statistically significant for October of the previous year. Negative correlation was also found for temperatures of the entire summer period from June to September of the previous year. The regional tree-ring chronology mainly shows two periods of highly reduced increment: from 1992 to 1996 and from 2003 to the end of the analysed period. The results thus confirm the hypothesis that the tree-ring width is in positive correlation with summer precipitation and negative correlation with summer temperatures. Also the results of the habitual diagnostics have shown a relatively low degree of crown transformation which indicates a weak or short-term stress load.

    The presented study deal with the dendrochronological dating of wood sampled from timbering in the Bochnia salt mine. The exact dates of felling trees that had been used for timbering were determined by applying the tree−ring analysis for wood from three mining chambers: the Passionis chapel, the Mysiur stable and the Rabsztyn chamber. It transpired that the analysed timbers originated from different periods representing the time interval between the seventeenth and nineteenth centuries. The wood from the Passionis chapel was dated 1652 while that from the Rabsztyn chamber comes from the eighteen century and from the Mysiur stable – from the eighteen and nineteen centuries.

    Opis:
    The aim of undertaken research was recognition the reasons of dying out the common juniper Juniperus communis L. ssp. communis population in the forest nature reserve “Jałowce” (Pomerania). Applied methods of dendrochronological analysis let to determine the age of juniper-stand in the reserve and describe the influence of climatic conditions on its growth. Obtained results testify to Juniperus communis chronology with signature WIE collected from 17 individual sequences which numbered 102 tree ring width and represented a time span 1903 to 2004. Such results described the juniper-stand in the reserve as ageing population with the oldest specimen at age 98 years. However, the last several years were characterised by the lack of strong growth depressions typical for earlier time periods with tree ring width ranged 0.7–1.0 mm (themean annual tree ring width amounted to 0.85 mm), but the visible symptoms of degeneration and dying out of protected common juniper population intensified probably because of its age.

    Opis:
    Tree−ring analysis of pine stands living under the influence of industry in south−eastern part of Silesia−Krakow Upland was performed for the last years. Now the new transect was added in the Olkusz region. Previous studies showed the distinct relationship between number of trees with observed reductions and distance from main source of pollution it this region. On the sites localised nearest to zinc−works "Bolesław" the value and the duration of reduction periods were the biggest. On the sites of new transect (OL VI) situated to the north from site OL 15, the influence of zinc−works is rather uncertain. Because of the time of occurrence and the distance form zinc−work, the reductions observed here seem to be the reaction to the other factor – perhaps the local source of pollution. To explain this matter further studies in this region should be done.

    Opis:
    The wild service tree (Sorbus torminalis L.) is a very rare tree species in Poland, which also represents the north-eastern border of its natural range. The majority of this species’ stands is found in Wielkopolska. This study was aimed at examining the relationships between growth and climate for trees of the species Sorbus torminalis L. growing in the Wielkopolski National Park and the forest district Pniewy (Wielkopolska). Samples for the analysis were taken from 63 trees. However, taking into account the missing growth rings and difficult identification of the tree-ring borders in sapwood, only ca. 30% of the samples could be synchronized and dated accurately. Applying classic methods of dendrochronological dating, a 94-year STW chronology was constructed, spanning the years 1920–2013. The chronology, in turn, was used as a basis for dendroclimatological analyses including correlation, response function and pointer years. Climatic data used in the analyses came from the meteorological station in Poznań; providing air temperature and precipitation for a period of 66 years (1948–2013) and 48 years of insolation data (1966–2013). Insolation had the highest negative and precipitation the highest positive impact on the annual growth in May and June. Positive pointer years could be linked to humid months with low insolation during the growth season, while negative pointer years are characterized by deficient precipitation, a large number of sunny hours and high air temperatures in the summer months.

    In homogeneous climate conditions Scots pine trees at different sites have similar short−term incremental rhythm. It was determined by the temperature of early spring and precipitation in June. Differences in the growth pattern are caused by various sensitivities of pines from different habitats to the temperature in May and precipitation in February and April of the current year.

    The research carried out was aimed at dendrochronological analysis of old timbers from the Gold Mine in Złoty Stok. The analysis resulted in 15 absolute datings of timbers of two tree species: Scots pine and fir. The established data fell into four last centuries. The oldest date, after 1667 AD, was obtained for fir wood from timbering of a shaft in the Masters' Adit (sztolnia Mistrzów), whereas the youngest one, after 1941 AD – for pine wood from the Prince's Adit.

    Opis:
    The intermediate cuttings have an important impact on the stand structure and productivity. Choosing the right method of the treatment performance is the decision, which is fundamental in shaping tree stands stability. The radial increment, apart from the natural growth potential of particular species, is influenced by many abiotic, biotic and anthropogenic factors, among which one can distinguish those that influence it directly, e.g. thinning. The study objective was to determine the effect of silvicultural treatments on the increment reaction of oak (Quercus sp.) stands in the Międzyrzec Forest District (eastern Poland). The empirical material was collected in six forest stands located in the Witoroż forest range. In each stand we cored 10 dominant and co−dominant trees (representing 1st and 2nd Kraft’s biosocial classes). After the measurements of the tree−ring widths and the synchronization of incremental series, the raw and standard chronologies were elaborated for each stand. In total, we analysed 8 treatments: six early and one late selection thinnings, and one late salvage thinning (tab. 1). For each treatment, three− and five−years’ value of mean tree−ring width was calculated for the period before and after the cut. Additionally, we calculated the incremental response parameters: recovery (Rc), resilience (Rs) and resistance (Rt) indices. For the majority of the analysed treatments, the cuts resulted in an increase in average tree−ring width both in the 3−, and 5−years perspective. However, statistically significant changes in this parameter occurred only in a few cases (fig. 2). The average values of incremental response indicators show that the investigated oak stands are characterized by a significant adaptive capacity and a rapid recovery of incremental capacity in the analysed time spans. At the same time, the low values of Rt index suggest that their growth resistance to disturbance caused by the thinning is rather low. The age of the stand at the time of the treatment significantly affected the incremental response parameters of the examined oaks. The older the stand, the incremental response was less intense.

    The aim of this study was to investigate differences in radial increment reaction of Norway spruces from the Beskidy Zachodnie Mountains (S Poland). Spruce stands were located at different altitudes and slope aspect. Two altitudinal zones were distinguished by a separating altitude of 900 m a.s.l. The dendrochronological belts, consistent in terms of radial increment, amount to 200−250 m in the lower zone, and narrow down to ca. 100 m in the upper one. Factor differentiating radial increment of spruces at various altitudes was temperature in September of previous year as well as precipitation in March and June of current year.

    Opis:
    The study analysed short−term rhythm of radial increments of spruces from different elevations and their climate drivers. Two Norway spruce stands were chosen at the lower and upper montane forest belt in Roztoka Valley (DR) (1000−1050 m asl, 49°13 N, 20°04 E) and in Hala Gąsienicowa (HG) (1500−1550 m asl, 49°13 N, 20°04 E). 20 trees were sampled and one increment core was taken per tree. The sampled trees were dominant or co−dominant individuals without visible damage. To remove the age trend, the tree−ring widths values were standardized to annual sensitivity indices. Principal components analysis, bootstrapped correlation and pointer years analysis were used to classify sensitivity of investigated series and identify the climate factors, which determined annual variability of the radial increments. Pointer years were also determined by using interval trend method. The first principal component (PC1) accounts for 39% of the variance among all tree−ring series. The second component (PC2) accounts for 15% of the variance among the tree−ring series and divides the series into two groups. This grouping seems to express the lower and higher locations of the sites. The sensitivity series of spruces from both sites had different as well as similar features. These differences resulted from different tree's reaction to temperature in early spring and precipitation in spring and summer. The similarity of increment reactions of spruce from both sites was caused by their similar sensitivity to sunshine duration and precipitation in January, temperature in June and July, sunshine duration in June. Cluster analysis confirmed the impact of the climatic factors on differences of increment reactions of spruces. A number of the pointer years was higher at site located in the upper montane forest belt. Their chronology also consisted a stronger climatic signal. The climatic sensitivity which was specificity for a given climatic belt was recorded into individual tree series. For that reason, the tree−ring width series of trees are useful in the estimate of a climate−increment relationship. They can also be used to dividing dendroclimatic belts.

    Opis:
    The aim of the research was to determine the impact of climatic conditions on the tree−ring width of Swedish whitebeam Sorbus intermedia (Ehrh.) Pers. growing in the urban conditions in Szczecin (NW Poland). The samples were taken from 26 trees growing along Rodziewiczówny, Ejsmonda and Santocka streets (left bank of the Odra river). On the basis of the tree−ring width measurements and cross−dating, two local chronologies (JS1 – Rodziewiczówny and Ejsmonda streets, and JS2 – Santocka street) were developed. Later on we indexed them (double detrending, least squares method and spline function) and subjected to the analysis of correlation and response functions. Growth−climate dependencies in both Swedish whitebeam communities are different. For the JS1 chronology the highest value of the multiple regression coefficient was obtained for air temperature, while for JS2 chronology for insolation and precipitation. For both sequences dependency on climate is similar in August and December of the previous year of vegetation and in January, February, April, June and July of the current year. The observed differences are the result of the impact of various factors related to human activity: traffic volume, soil pollution (mainly heavy metals and salt), damage to roots, trunks and crowns.

    The aim of this study was to assess the impact of climatic factors (temperature and precipitation) on tree ring width of larches from stands localised in southern part of Poland. Total ring as well as early− and latewood widths were taken in consideration. At the beginning authors used only standard processing and methods. Classic approach were insufficient to make some data useful for the correlation analysis, so authors decided to use more robust, custom methods.

    The study presents results of dendrochronological analyses of Scots pine (162 trees) and English oak (97 trees) from 13 research plots located in NE Poland. The investigations resulted in construction of local chronologies (six for oak and seven for pine), which in turn enabled to define new regional chronologies; 2_NE_PL for pine, covering the period 1738−2003 AD, and Q_NE_PL for oak, 308−year long (1696−2003 AD). The elaborated chronologies allow for absolute dating of wood and yield new data on the extent of dendrochronological signal.

    tree−ring reductions
    Opis:
    The main objective of the research was to evaluate the incremental response of Douglas fir and Scots pine subjected to strong environmental stress to variable thermal and precipitation conditions. We also attempted to determine periods of tree−ring width reduction caused by strong anthropopressure associated with the activities of nearby industrial plants, which are burdensome for the environment. The studied forest stands are located in the Kędzierzyn Forest District, in Kotlarnia forestry (50°27'59'N, 18°38'42'E) approximately 8 km away from the nitrogen production plants. We used standard methodology applied in the dendrochronological studies with the support of the TSAP−Win, Cofecha, Arstan and Quercus 06.01 softwares. We found that Douglas fir and Scots pine stands growing in the permanently damaged zone due to the adverse effects of industry responded to meteorological conditions in a manner typical of the species. In the study of the relationship between weather and growth, thermal and precipitation conditions were more important in the current year than in the year preceding the increment. A similar distribution of reductions and periods of partial regeneration in both species were also observed. In the same multi−annual period of 1961−1991 deeper reductions of annual increments were observed in Douglas fir (>70%) than in Scots pine (in the range of 50−70%). Conditions, in which trees grew in the Kędzierzyn Forest District, contributed to the decrease in annual increments of both Douglas fir and Scots pine, while the previous species turned out to be a more sensitive one, which had been indicated by other researchers ealier.

    Opis:
    Tree−ring analysis has been used to evaluate the influence of industrial pollution on Scots pine (Pinus sylvestris) growing in the Tarnobrzeg region. 237 samples were taken from stands located in two profiles to picture dependence of health conditions of trees on distance from the emitter. The Tarnobrzeg Sulphur Works was the main source of pollution in that region. Factories in Mielec and Nowa Dęba as well as the Połaniec Power Plant could be additional sources of emission. Response of trees to anthropogenic stress was clearly visible in the years 1970−1990, when growth reductions occurred at the majority of the investigated trees. At the beginning of 1990s the decreasing trend stopped and wider tree−rings could be observed.

    Opis:
    The anatomy and functioning of stem secondary xylem in relation to the decline of European ash (Fraxinus excelsior L.) was examined and the hypothesis that declining trees show changes in the structure of wood, resulting in impaired water transport was tested. Anatomical analyses were carried out on samples comprising annual rings formed between 1970 and 2009 and collected at the breast height of the main stem of fifteen trees 40−90 years old. Trees were based upon health condition and classified as healthy, weakened or dead. Tree−ring widths as well as diameter and density of earlywood vessels were measured and the theoretical hydraulic conductivity index through the secondary xylem calculated by application of Hagen−Poisseuille formula. Over the whole investigated period the smallest early vessels were attribute to ashes dead at the time of sampling. In the period when dieback symptoms where manifested in the stand, the diminishment of vessels diameter occurred in weakened and eventually dead trees, whereas healthy trees produced even slightly larger vessels than before. Having large vessels implies that healthy trees were able to keep high hydraulic conductivity index, whereas trees in decline at this time produce smaller vessels and hence had reduced conductivity in respect to previous.

    Opis:
    A local tree ring chronology for Norway spruce from the Ormtjernkampen National Park in Norway has been developed for the years 1808−1996. The widths of annual tree rings are shown as absolute [mm] and standardised values. The dendroclimatic analyses have demonstrated that high June−July air temperatures and atmospheric precipitation in January have a stimulatory effect on ring formation. The high air temperatures of April in the current year and of June and September in the year prior to ring formation have a limiting effect on radial increment.

    Opis:
    The main aim of this study was to analyze the variability of width as well as content of stable oxygen and carbon isotopes, and radiocarbon in Pinus sylvestris L. tree rings. Analysed Scots pine stand grew on the fresh mixed coniferous forest habitat type on site located in the vicinity of the power plant in Łaziska Górne (southern Poland). The combined usage of tree ring width and isotopic data allowed to identify how investigated trees have adapted to the pollution. Strong increase of industrial pollution emission was noted on the investigated site between 1960s and 1980s. During that time, the trees reduced their radial incement and the heterogeneity of their reaction increased, whereas their sensitivity to short−term impulses to changes in the environment conditions weakened. We observed depletion rates of 14C and δ13C concentration in α−cellulose related to the CO2 emission into the atmosphere in the processes associated with the fossil fuels combustion. Prior to 2000, a decrease in stomatal conductivity was associated with a minor changes in the net photosynthesis rate and that elevated CO2 increased intrinsic water use efficiency (approximately by 40%).

    Opis:
    The paper compares the properties of Norway spruce (Picea abies (L.) Karst.) wood from stands growing in the lower and upper subalpine forest zone in terms of the tree−ring width, the share of latewood and the wood density. The investigation concerned material originating from plots established within the boundaries of the south−western incidence of spruce in Poland. Plots were located in the Sudety Mts. and in the Carpathians (tab. 1). On each plot fifteen Norway spruces were chosen and increment cores were sampled using the Pressler borer. The surface of the cores was smoothed and the tree−ring width was measured. The latewood zones were determined and the share of latewood was calculated. Then, the cores were divided into 2 cm sections, for which the relative wood density was determined. Tree−rings were wider in trees growing in the lower when compared with those from the upper subalpine forest zone (tab. 2). Weak negative correlation was revealed between the elevation and the tree−ring width (r=–0.308). The latewood share was slightly higher in trees from the upper than those from the lower subalpine forest zone (tab. 2). However, no statistically significant correlation between the latewood share and elevation was recorded. The wood density was slightly lower in trees from the lower than those from the upper subalpine forest zone (tab. 2), but the difference was not statistically significant. The correlation between the wood density and the elevation turned out to be insignificant.

    Opis:
    Content fluctuations of the oxygen isotope δ18O in the Devon Island ice core during the last 100 000 years are a measure of climate fluctuations in the Northern Hemisphere. The course of content of the oxygen isotope δ18O and the sums of solar radiation reaching the upper edge of the atmosphere are characterized by approximate minima and maxima (by positive correlation). This proves that, during the last hundred thousand years, climate fluctuations (cooling and warming) in the Northern Hemisphere were conditioned by long-term changes of the orbit and altitude of the Earth's axis. Climate fluctuation forecasts for the Northern Hemisphere were developed for the next 40 000 years on the basis of the established periods of change of the oxygen isotope δ18O and the known solar radiation periodicity. Climate changes in Europe during the last 25000 years were presented together with a forecast for 1000 years (according to organic substances in deposits and radiation) as well as climate changes in Europe in the period from -500 years BP to 2100 AD (according to δ18O and pine tree-rings). It showed that climate changes depended on the concentration of planet mass in relation to the ecliptic plane (from the gravitational impact of planets on the Sun). Concentration courses of planet mass in the Solar System and climate fluctuations in the Northern Hemisphere were compared. Of interest are examples of synchronic fluctuations, i.e. dispersal of planet mass in the Solar System, the widths of pine and spruce tree rings and air temperatures in Europe.

    Paper analyses relationships between radial growth and seven crown−related parameters (crown length, relative length, width, slenderness, projection area and volume as well as single tree space) for ten alien and native tree species growing in 'common garden' conditions in the WULS−SGGW Forest Experimental Station in Rogów (central Poland). Significant correlation was found between 10− and 15−years mean tree−ring width and all analysed crown parameters as well as single tree space for Abies grandis, Abies nordmanniana and, except for crown length and its relative length, for Pinus sylvestris. No relationship was observed between radial increment of Larix decidua, Pseudotsuga menziesii and Quercus rubra and any of analysed crown parameters.

    Opis:
    Scots pine is the most common tree species in Poland with the share in the species structure of Polish forests exceeding 58%. The most dangerous pathogen of this species is Phellinus pini (Brot.) Pilát), which causes the white pocket rot (also called red ring rot) of pine heartwood. It is estimated that as a result of the fungus’s activity, about 8% of annually harvested pine stems is damaged and worthless. As the Ph. pini damages only heartwood, it is often recognized that its occurrence has no influence on the tree’s physiology. As it is still unknown whether the presence of this fungus also does not affect the cambium responsible for the radial growth. We carried out studies in Scots pine stands located in the Radziwiłłów Forest District (central Poland). We investigated trees from 5th and 7th age classes (Biała Góra and Budy Stare forests, respectively). A total of 60 trees were sampled (30 per site). Half of them were specimens showing advanced symptoms of sickness, while the others were healthy specimens with no evidence of infection. From each tree we took one increment core and measured the tree−ring widths. Average tree−ring width was in case of healthy trees significantly higher than for sick trees. The research showed a significant, even of a dozen percent, reduction in the annual increment of infected trees in relation to healthy trees growing on the same site. Presumably, unidentified chemicals secreted to the cambium by the growing mycelium of Ph. pini may be responsible for this. It also seems that this relationship is progressing with the growing age of tree stands and is particularly visible in old stands, for example in reserves. Thus, Ph. pini could be one of the factors limiting the natural age of pine trees and accelerating their dieback. We also found that the growth of trees affected by the disease is influenced by a factor other than climatic, disturbing the natural rhythm of their radial increments. This factor is most likely the presence of mycelium of Ph. pini in the wood.

    Opis:
    The study makes an attempt to analyse the width of annual rings, the width of the latewood zone and the proportion of the latewood within juvenile wood along trunks of Scots pine (Pinus sylvestris L.) trees and to verify the hypothesis about the heterogeneous properties of juvenile wood in a single trunk. It was found that the above-mentioned macrostructural elements of wood structure showed a curvilinear correlation with the height of measurement points along the tree trunk. As the distance from the base of trunk increased, the width of the annual ring and the width of the latewood zone decreased, while the proportion of the latewood increased. These types of changes can affect positively physical and mechanical properties of wood tissue. It can be assumed that there is a mechanism which modifies properties of juvenile wood causing axial diversification of the analysed type of wood tissue. It is probable that axial heterogeneity results in advantageous changes in the mechanics of the tree trunk.
