Opis:
W artykule przedstawiono program TRIFOUR, przeznaczony do poszukiwania trendu oraz analizy cykliczności w sekwencjach dendrochronologicznych. Program akceptuje dane wejściowe zapisane w kilku formatach (m.in. TUCSON i CRN). Analiza może być prowadzona zarówno dla całej sekwencji, jak i dla pewnego jej fragmentu lub dla wielu fragmentów jednocześnie. Program oblicza współczynniki trendów wielomianowych, wykładniczych, potęgowych, hiperbolicznych i liniowych oraz trendy typu średnich ruchomych, a bieżące oszacowanie trendu może wykorzystać do przekształcenia analizowanej sekwencji w sekwencję indeksów dendrochronologicznych. W ramach analizy cykliczności obliczane są wartości empirycznej funkcji autokorelacji, periodogramu i gęstości spektralnej; dzięki opcji podziału sekwencji na odcinki o jednakowej lub dowolnej długości można śledzić ich zmienność w czasie. Zarówno same sekwencje, jak i wszystkie wyniki obliczeń są zapisywane na dysku w plikach graficznych lub/i tekstowych
The paper presents the TRIFOUR software designed for trends and cyclicity analyses of dendrochronological sequences. The software accepts data written in several formats (e.g. TUSCON and CRN). Analysis can be run for the full sequence, for a selected fragment or simultaneously for several selected fragments of data sequence. The software calculates coefficients of polynomial, exponential, involute, hyperbolic, linear and moving-average trends. Current trend estimation can be applied to transformation of analyzed sequence into dendrochronological indexes sequence. Cyclicity analysis includes values of empirical correlation function, periodogram and spectral density. Sequence fragmentation into equal- or random-length parts enables recognition of their variability with the time. Both the sequences and all results are recorded into hard disc as graphic and/or text files

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:
Dendrochronological analyses undertaken in the 1990s allowed for the establishment of a new time-line in determining a more precise date for the origins of the Polish state. It appeared from these data that the creation of the Polish state occurred much later than it had been thought before. The formation of the early medieval state was initiated by vast and multi-faceted cultural changes occurring on the territory of the Gniezno plateau at the turn of the 9th and the 10th century. As the culminating point of that process, one can consider the consolidation of the local population in reaction to the threat posed by the outbreak of the great uprising of the Slavs along the Elbe River in 936-940.

Opis:
Dendrochronological methods were used to analyze geomorphic processes in the Arctic area. Samples of dwarf shrubs, Salix polaris and Salix reticulata, were collected from different morphodynamic surfaces: talus cones, debris flow tracks and fluvioglacial terraces. Clearly visible, countable and measurable annual growth rings (ranged from relatively wide 0.8 mm in width, to extremely narrow rings less than 0.01 mm in width) and wood anatomical changes (scars, tension wood) allow for using these species in dendrogeomorphological examinations. The age of the dwarf shrubs showed the minimum time during which the surface was disturbed by mass movements (e.g debris flow tracks developed in the early 1950s and 1970s) or the time of plant colonization which indicates disappearance of geomorphic processes (e.g. determining the age of fluvioglacial terraces in the Arie valley). Dwarf shrubs represent problems in synchronization of growth curves (discontinuous rings, missing rings, asymmetric geometry of stem). Samples taking from random surfaces can reflect only local phenomenon, which are limited to microtopography. It is necessary to -analyze material from entire area of geomorphic form.

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:
Subfossil trunks of oak (Quercus robur L. and Q. petraea Lieb.) are fundamental for construction of long dendrochronological standards for southern Poland. In the last three years over 400 new oak trunks from alluvial deposits from the basins of the rivers Vistula and Odra were analysed. Most trunks came from the last 2500 years and the produced local chronologies permitted for improvement of the standard chronology POLAND2, covering the period 474 BC-I 555 AD. Subfossil oak trunks from several sites in the river Vistula basin (Grabie, Wolica, Podolsze and others) and from alluvia of the river Odra in Wrocław enabled construction of a new long chronology C_3000E, spanning the years 1795-612 BC. This chronology was absolutely dated through teleconnection with standards for southern Germany. A row of floating chronologies, dated with the radiocarbon method, was established for the older periods of Holocene. They cover the following intervals: ca. 670-400 BC, ca. 2200-1900 BC, ca. 3400-3100 BC, ca. 3800-3600 BC and ca. 6650-6150 BC. Subfossil oak chronologies constructed by the author, together with standards based on living trees, monuments of wooden architecture, and archaeological timbers from Wielkopolska (449- I 994 AD), Lower Silesia (780-1994 AD) and Małopolska (910-1997 AD) practically allow for absolute dating of oak timbers from the area of southern Poland coming from the last 4000 years.

Opis:
The introduction of foreign tree species to new areas facilitates an increase in species biodiversity and possibilities for growth of tree stands. Many years of research related to survival rate, basic growth features and evaluation of a sensitivity to climatic conditions of a new habitat is necessary to achieve a successful introduction. The paper presents the results of the research on the adaptation of grand fir to the climatic conditions in the provenance trial located in the lower montane forest belt. The dendroclimatic research has concerned the offsprings of 7 grand fir provenances originated from North America. A total of 24 trees from each provenance were selected and two cores from each tree were taken. Principal component analysis of tree-ring widths was used to classify the provenances. The climate elements described by PC1 and PC2 were identified on the basis of bootstrap correlation function. Survival rate, height and diameter at breast height of trees were also analysed. The features of the studied provenances showed significant differences. The variation of the inter-provenance survival rate and the increase in tree height of particular provenances were determined principally by the genotype. Grand firs trees from Region I exhibited superior survival rates and better dynamic increases in tree height. The variability of these two features had the character of clinal variation because they primarily depended on the elevation and the latitude of the maternal tree stands. Two groups of provenances which were connected with the regions of their natural distribution were characterized on the basis of the features of the short-term rhythm of the radial increments. The provenances of two specific groups revealed different sensitivity to temperature, rainfall, humidity and sunshine. The greatest effect on the variation of radial increments had been produced by the moisture and pluvial factors whilst the solar factor had produced the least effect on it. The air temperature made also a relatively high contribution to their radial increments. Grand fir trees from the Salmon River provenance in British Columbia provided the best trees from the cultivation point of view. The provenances from Vancouver Island and the western slope of the Cascadian Mountains in Washington State have been regarded as the best for introducing and acclimatising to the conditions of the Carpathian Mts.

Opis:
Shrubs are widespread at higher altitudes and latitudes. Dendrochronology of shrub growth has been intensively studied in the circumpolar Arctic, Mediterranean and Patagonia. However, relatively little is known about shrub growth responses to climate change on the Tibetan Plateau. Herein, we investigate climate sensitivity of Salix oritrepha growth along a north–south (35–39° N) latitudinal gradient on the north- eastern Tibetan Plateau. Four S. oritrepha shrub sites were selected for dendrochronology study. Pearson and partial correlation analyses were used to estimate strength of the climate sensitivity of the growth time series at each site. We found that not all of the site chronologies show consistent variations. Despite of this, its ra- dial growth was primarily limited by the July mean temperature across the latitudinal gradient, and warming summer climate tends to increase the growth of S. oritrepha on the northeastern Tibetan Plateau.

Opis:
The relationship between tree-ring growth and climate in Quercus brantii, a widespread and dominant tree species in Zagros-Anti-Taurus Mountains, was investigated by both age-dependent and independent approaches. A total number of 118 trees were sampled in a region where severe Mediterranean climate prevailed. An overall chronology plus three age-dependent chronologies of <80, 80 to 160 and >160 years old were constructed to study growth-climate relationships based on an integrated approach of principle component stepwise regression followed by complementary response function analysis. High age heterogeneity of overall chronology diminished its climatic signals and growth priority was significantly presented in the models. Biennial and triennial precipitation variations were highly related with annual tree ring growth of young and old oaks, respectively. However, hot growing season negatively affected all age-dependent chronology indices. By increasing tree ages the negative effects of warm autumn prior to growth decreased and late winter fall became a limiting climatic factor in old trees. Results of response function analysis also revealed that all oak trees from each age classes were sensitive to increasing April temperature. It’s anticipated that, regarding the trends of late frost, this species will face with many challenges in this region and similar areas.

Development of the Early Medieval stronghold settlements in Wielkopolska (Great Poland) connected with the process of Polish state formation has been outlined. The new established chronology of the strongholds based on dendrodates, showed their younger age than it was previously deduced from archaeological chronology. The stronghold architecture was the main feature of the medieval cultural landscape of the region. In the light of historical records, archaeological data and palaeobotanical reconstructions, the Early Medieval Great Poland was a land of strongholds and arable fields.

Opis:
Iberian temperate forests are distributed along the boundary between the Atlantic and the Mediterranean biogeographical regions, and represent the south-western range edges of diverse European broadleaved deciduous tree species. Trees growing at the boundary between Atlantic and Mediterranean biomes suffer from different stresses, including increasing moisture deficit which has been identified as one of the main limitations for growth. In this work, dendrochronological techniques were employed to characterize the radial growth of Acer campestre L., Fagus sylvatica L., Fraxinus excelsior L., and Quercus robur L. in a mixed forest in northern Spain, and examine its relationships with local climate near their south-western range edges. Acer and Fagus tree-ring chronologies showed the highest common signal and the strongest responses to climate. Positive effects of precipitation, especially in the previous December and current summer, were relevant for growth of all species. Only Acer growth showed a detrimental effect of maximum diurnal temperatures in the previous autumn and current summer, while Fraxinus and Quercus growth was benefited by above-average winter temperatures. Cloud cover strongly improved the radial growth of all species, probably because cloudy conditions mitigate the detrimental effects of summer water depletion and low winter temperatures. The beneficial effects of precipitation and cloudiness on tree growth were temporally unstable and have become significant generally since the 1970s, suggesting that rising temperatures and decreasing rainfall shape radial growth-climate relationships of broadleaved deciduous trees near their southern range edges.

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.

Paper presented the results of excavations conducted on the site Čierne zeme at Zvolen (Slovakia). Within the trench a segment of Hron river paleochannel was uncovered. It was partially filled with cultural sediments, which were naturally accumulated as a result of undercutting the banks of Hron during the periods of water surge. The trunks discovered within the sediments were radiocarbon dated to the time span between 2470 and 2280 BC. Besides them cultural layer yielded also some stone artifacts and collection of pottery fragments. The second one represent mainly the cultural traditions (e.g. Makó-Kosihy-Čaka culture) from the turn of Eneolithic and Bronze Age periods, what corresponds well with the radiocarbon dating of wood. Described site is another settlement point dated to this period in the Zvolen Basin. Younger group of pottery originates from Modern Era (16th-17th century AD) and may be connected with existence of communication route running along Hron river.
