Opis:
This study investigates the effect of the enrichment of Scots pine stands with a common beech understorey on changes in the species composition and selected life traits of an important zooindicator group, such as the ground beetles (Col. Carabidae). The field investigations were carried out in a fresh coniferous forest in the Myszyniec Forest District (N Poland) in stands with (P+) and without (P) beech in the understorey. Each treatment was repeated four times. In each repetition, six pitfalls were installed. The traps were replaced 13 times, every two weeks, from April to October. In total, 4412 specimens classified into 25 species of ground beetles were captured. The tree stands with the beech understorey were observed to contain a significantly higher number of species than the ones with the beech undergrowth. Also, the value of the Shannon index of species diversity (H’) and mean individual biomass (MIB) were significantly higher in the treatment with the beech understorey. Principal Component Analysis showed variations in Carabidae assemblages within the analysed types of forest. Pterostichus oblongopunctatus, Pterostichus aethiops and Pterostichus vernalis were more strongly correlated with the stands without beech understorey. The stands enriched with the beech understorey correlated with the occurrence of large zoophages: Carabus arvensis and Cychrus caraboides, and hemizoophages of the genus Amara. An in−depth ecological characterisation of the captured Carabidae showed that the dominant ground beetles in the investigated forest habitats, in terms of the number of caught individuals and species, belonged to forest zoophagous carabids characterised by moderate requirements for moisture in a habitat, and having the spring type of development. Representatives of large zoophages and species with the autumn type of development, i.e. species associated with later ecological succession stages, were more numerously caught in the pine stands without the beech understorey The study provides evidence that justifies the planting of deciduous undergowth in monoculture coniferous pine tree forests. The presence of an understorey contributes to higher: richness of Carabidae species, values of the MIB and abundance of large forest species presenting the autumn type of development, that is the species, which are characteristic for forest areas representing a highly advanced succession stage.

Opis:
The fallow deer is a species with a wide range of occurrence that primarily inhabits deciduous and mixed forests in Europe and North America. However, it also inhabits boreal environments that are rich in understory, fields, and meadows. Some parts of Poland have a high density of fallow deer due to human activities. Despite its extensive distribution, many aspects of this species ecology remain unexplored. Our research was performed in Osie and Dąbrowa forest districts in the Tuchola Forest (northern Poland), where the fallow deer is an introduced species. The objectives of the study was to determine the factors influencing the winter spatial distribution of the fallow deer in an environment dominated by Scots pine forests. Using the pellet−group count method, four 100 m2 circular plots (5.6−m radius) were located 100 m apart one from the other on the perimeters of 25 equally distributed 500×500 m squares (16 circles/square) within the research area. The mean density of the fallow deer pellets ranged widely across the study area (0.5–5.6 (±1.27) pellets/square). The most significant factor affecting their winter spatial distribution was distance to water. The redundancy analysis showed that in winter, fallow deer avoids the boreal forests and chooses meadows, pastures, and cultivated fields. The fallow deer in the Tuchola Forest occurred mainly along the watercourses and meadows.

Opis:
The studies were conducted on three plots, established in 100−130 year old Scots pine (Pinus sylvestris L.) stands (type: Pinetum vaccinio−mirtyllosum) situated in the southern and central parts of Lithuania (Kaunas and Vare˙na districts). Their canopy closure was from 0.6 to 0.8. The study areas comprised of a mature stand (control) and clear−cut felled in spring 2016 and tilled after 5 months. Altogether 30 litter samples (five per stand) were taken from randomly chosen locations twice: the first sampling took place one month after cutting (in May) and the other after five months (in October). In total, 921 adults and larvae representing 49 species of rove beetles (Coleoptera: Staphylinidae) were collected. The higher number of individuals was harvested in control stands (fig. 1a, tab. 1). The collected individuals were significantly more abundant during the second sampling in all studied stands (fig. 1b, tab. 1). In the same way the higher number of species was detected in control stands, but significant differences were observed only during the first sampling. Amount of forest species differed insignificantly between control stands and clear−cuts, while the rate of zoophagous species was significantly higher in control stands (fig. 2a, tab. 1). The number of mixophagous species was significantly higher in clear−cuts during the second sampling (fig. 2b−c, tab. 1). Both the felling and the tilling had a distinct impact on transformation of rove beetles assemblages in clear−cuts comparing to the mature stands (fig. 3). Ischnosoma splendidum, Othius subuliformis, Stenichnus scutellaris, Trimium brevicorne, Xantholinus tricolor, Philonthus cignatus and Sepedophilus sp. were revealed as associated with mature pine stands sites, while only Acrotona parens and Amischa analis were connected with clear−cuts (tab. 2). We propose to use these two species as indicators of strong transformation of rove beetles assemblages due to clearcutting and management. The results of the study proved that negative impact of clearcutting on number of individuals and number of forest species in rove beetles assemblages is distinct even in short period after cutting as well as that transformation of rove beetles assemblages increase after cutting of stand, especially after tilling.

Opis:
W dotychczasowych badaniach wiele uwagi poświęcano wpływowi ciągów komunikacyjnych m.in. na zanieczyszczenie gleb metalami ciężkimi, utrudnioną migrację zwierząt, hałas czy synantropizację szaty roślinnej. W niniejszej pracy zbadano oddziaływanie drogi o bardzo małym natężeniu ruchu na roślinność zielną, a w szczególności na występowanie 3 gatunków roślin z rodziny wrzosowatych: wrzosu zwyczajnego, borówki czarnej i borówki brusznicy, oraz zmienność pH gleb. Obserwacje prowadzono w drzewostanach sosnowych w siedlisku boru świeżego i boru mieszanego świeżego na terenie Puszczy Noteckiej. Założono dwanaście prostopadłych do osi drogi prostokątnych powierzchni doświadczalnych – transektów. Na każdym z nich wyznaczono 3-4 działki badawcze zlokalizowane w różnej odległości od krawędzi jezdni. Na działkach przeprowadzono obserwacje roślinności i pomiary pH gleb. Uzyskane z transektów wyniki uśredniono w obrębie działek ulokowanych w tej samej odległości od drogi i porównano z innymi stosując metody statystyczne. Przy drodze próchnica leśna okazała się istotnie mniej kwaśna niż w głębi drzewostanu, obficiej występowała roślinność zielna, w tym wrzos zwyczajny, rzadziej natomiast pojawiały się borówka czarna i brusznica, których to częstość występowania istotnie rosła wraz ze zwiększaniem odległości od drogi.
The development of the transportation network brings both benefits and threats. Much attention is paid to soil contamination with trace elements, difficulties in animal migration, noise propagation or synanthropisation of the vegetation cover. This paper deals with the effect of provincial very low-volume road No. 150 on the herbaceous vegetation cover, especially on the occurrence of 3 species of the heather family: Calluna vulgaris, Vaccinium myrtillus and V. vitis-idaea. Observations were conducted in pine stands in fresh coniferous forest and fresh mixed coniferous forest sites in the Puszcza Notecka Forest, Poland - one of the larger forest complexes in Europe. Twelve rectangular experimental sites were established perpendicular to the road axis, called belt transects. Each of them consisted of 3-4 plots located at different distances from the pavement edge. Measurements and estimations of herbaceous vegetation cover and pH soils were recorded for the each plots. Values from all belt transects were approximated within plots at the same distance from the road and then compared using statistical methods. By the road humus was a less acidic than in the depth of the tree stand, there was more abundant herbaceous vegetation, including Calluna vulgaris, but rarely appeared Vaccinium myrtillus and V. vitis-idaea whose incidence is increased with increasing distance from the road edge.

Opis:
The aim of the study was to determine the rate of mineralization of needles in a pine stand in relation to site and to microbiological conditions occurring on dune slopes of contrasting aspects. The research was conducted in the old−growth pine forest overgrowing a latitudinally located dune in the Bydgoska Forest (N Poland). On contrasting dune slopes (northern and southern) rate of mineralization of pine needles was investigated in the 2−years experiment (2012−2014) with the litterbag method. Besides, following investigations were conducted in the middle part of both slopes: 1. dynamics of soil moisture and soil temperature were measured at a depth of 3 cm for 18 days during the 2013 growing season (interval of 2 weeks was applied) and 2. populations of bacteria and fungi were determined for all subhorizons of organic soil horizon (Ol, Of, Oh) as well as for a mineral horizon (AEs) of both soils. Weight loss of needles was found to be higher on northern than on a southern slope what was consequently stated for all 4 terms of taking measurements (6, 12, 18 and 24 months after placement of litterbags). The discrepancy has increased with time and after 2 years it equaled 14.7% when the loss was 61.1% for northern and 46.4% for a southern slope. It could be surprising that such differences were found in spite a sunny slope was characterized by stated in a study higher soil temperature. It should have a stimulating effect on mineralization of organic material; however a soil located on a southern slope was also found as much drier. Thus, the periodic deficiency of soil moisture was indicated as a limiting factor for occurrence of both bacteria and fungi on a southern slope due to the numbers of both groups of microorganisms were much lower on the slope than on a northern aspect. Conditioned by more favourable site parameters, higher number of microbial population occurring on a shadow slope could explain higher rate of mineralization of needles stated for the slope aspect. The moisture factor can be of especially high significance for microbial occurrence and activity and thus for litter decomposition just in dry inland dune ecosystems. It was concluded that in relatively monotonous pine forests overgrowing dry and poor in nutrients soils of inland dunes the slope aspect is an agent significantly differentiating both site and soil microbial conditions.

Opis:
The assemblages of Coleoptera have been examined in the managed and reserved mature pine forests of Lithuania since 1997. Beetles have been sampled from the forest litter using sieves. The present study is based on the data of 20 litter samples (10 samples per each stand) taken in the period from October 2013 to February 2014. Each sample was compiled of 5 smaller ones taking all litter (up to mineral layer of the soil) from 0.04 m2 plot. During the study a total 450 adults representing 69 species of beetles was discovered. Both the average number of species and the number of individuals were found to be higher in the samples taken in reserved forest and made 10.7±1.4 and 27.2±4.9, whereas in managed forest they made 9.7±1.1 and 17.8±3.4, but the differences were not statistically significant. The proportions of phytophagous, mecetobionts and saprophagous were also bigger in reserved forest: 9.5±2.0, 7.8±2.2, 3.1±1.0 than those in the managed forest, where these groups consisted of 8.0±1.8, 4.9±1.7 and 2.8±1.6 percent of the total number of individuals in the sample, respectively. The opposite proportions were detected for zoophages, which were more ambiguous in the managed forest and were by 76.0±2.5 higher than those in the reserved forest 72.8±3.2. These differences were not statistically significant. A non−metric multidimensional scale (NMDS) using Bray−Curtis similarity matrix indicated low differences of the Coleoptera assemblages between investigated sites (final stress=0.22). The analysis using RDA showed some differences between Coleoptera assemblages inhabiting reserved forest (R) and managed forest (D), which were correlated with proportions of humified mortmass (+0.88) and biomass of moss (–0.63 and –0.71). The dissimilarity index calculated using the algorithm SIMPER, was quite high (71%), but the obtained results showed a relatively low diversity of beetle assemblages in both forests. It means that the process of transformation of the managed forest into reserve is very slow, most likely due to the fact that restoration of the microhabitats is particularly slow. Low differentiation of Coleoptera assemblages dwelling in litter is associated with low dispersal power of most coleopteran species. Thus, the establishment of new reserves in old growth pine forests can not stimulate fast increase of specific beetle diversity mainly because the regenerative processes of microhabitats seem to be extremely slow. The specific diversity of beetle assemblages was slightly higher in the reserved forests, but it was not confirmed statistically. In comparison with the managed old growth pine forest the period of fifteen years of reservation of old growth pine forest has only a very low effect on specific diversity and ecological specialization of the beetles.

Opis:
The main aim of the study was to determine changes in the species composition and structure of natural tree stands in the Białowieża Forest (BF), which occurred in the years 1975-2012, as well as to evaluate their trends, directions and rate. The study was carried out on 121 permanent research plots (50×50m), which represented the most important forest phytocenoses in BF, i.e. fresh pine-whortleberry forest Vaccinio vitis-idaeae-Pinetum Sokoł. 1980, fresh mixed spruce-reed grass forest Calamagrostio-Piceetum Soko³. 1968, oligotrophic form of hornbeam - bastard balm forest Melitti-Carpinetum Soko³. 1976, different forms of linden- hornbeam forest: Tilio-Carpinetum Tracz. 1962, alder-ash forest Fraxino-Alnetum W. Mat. 1952 and sub-boreal spruce forest on bog moss Sphagno girgenshonii- Piceetum Polak. 1962. On the plots selected, there was measured the diameter at breast height (DBH) of all trees, as well as every tree and shrub up to 1.3 m high was counted and described with reference to species. The measurements and observations were regularly repeated every 10-15 years. The results showed that over the last period of nearly 40 years, there has increased a share of common hornbeam Carpinus betulus L. in the structure of forest stands in numerous BF associations. This tree species has expanded into different forest habitats including poor, medium fertile and wetland sites. The results obtained indicate a trend towards formation of linden-hornbeam forests in BF phytocenoses. The most evident changes were recorded in hornbeam - bastard balm forest. In natural conditions of the majority of forest associations analyzed, there prevailed hornbeam trees in forest regeneration, except for the stands in fresh mixed pine forest and spruce forest on bog moss. In the latter two cases, hornbeam showed signs of its presence in the last observation period. Norway spruce (Picea abies L.) retreated into oligotrophic forest associations. In the recent decades, spruce populations have been dramatically reduced in the stands in mixed coniferous and different kinds of broadleaved forests. There have also decreased a share of light-demanding tree species, such as Scots pine (Pinus silvestris L.), pedunculate oak (Quercus robur L.) and silver birch (Betula pendula L.) in BF tree stands, including their regeneration-layer. Especially, Scots pine regeneration has not been successful. In the short period of time (about 15 years) there has been observed rapid and outsized reduction of ash Fraxinus excelsior L. populations in natural conditions of alder-ash forests. All through the last 10-15 years, there has been also observed increased rate of change in stand species composition. The trend and rate of change in stand species composition point out to a possibility of human intervention towards stimulation of natural regeneration so as to preserve valuable populations of threatened tree species in the Białowieża Forest.

Opis:
The utility of phytocenotic indices in the diagnosis and classification of forest sites might be limited because of vegetation degeneration in managed forests. However, even in secondary communities it may be possible to determine indicator species, although these may differ from typical and well known plant indicators. The aim of this work was to assess the vegetation diversity of Scots pine stands in representative forest site types along a moisture and fertility gradient. In total 120 sample plots from Turawa forests were included in the study. These plots represented young (21–40 years) and old (> 80 years) Scots-pine-dominated stands. The forest sites were categorized according to Polish site classification. Four site categories were studied: Boew (very nutrient-poor and mesic sites), BMoew (nutrient-poor and mesic sites), BMw (nutrient-poor and moist sites), LMw (quite nutrient-rich and moist sites). The species composition of the forest patches studied hardly differed among forest site types. Almost all of the vegetation in site Boew was different from both moist site types (BMw and LMw). Sites Boew andLMwhad the exclusive species determined as site indicators. Moreover, young stands had their own site type indicator species which differed from old stands. Numerical classification showed that only two plant communities were widespread: Leucobryo-Pinetum in Boew and BMoew, and the community of Pinus sylvestris and Molinia caerulea in BMoew, BMw, LMw. In secondary communities typical indicator species may not be useful, but it is possible to determinate species that are locally unique to forest site type. Despite the convergence in the composition of the plant community resulting from tree stand unification, plant communities have the capacity for a more diverse composition. Tree stand conversion can increase phytocenotic diversity.

Opis:
The paper presents the results of study on heavy metals in needles of Pinus sylvestris in selected pine forests in Słowiński National Park. It was evidenced that heavy metal contents (Zn, Cu, Mn and Fe) in needles of Pinus sylvestris varied depending on the metal, the age of the needles and the humidity of a forest complex. Variation coeffi cients of such metals remained at the level of: 13–30% (Zn), 3–6% (Cu), 13–34% (Mn) and 12–30% (Fe) depending on the age of the needles. In the case of Zn, Mn and Fe higher concentrations of researched metal were found in the 2-year-old needles than in 1 year old needles, and in the case of Cu in 1 year old needles than in 2-year-old needles. The increase of zinc concentration found in 1-year-old needles after rainfall sums was (Bw, r = 0.67, p < 0.05, n = 24) and (Bśw, r = 0.39, p < 0.05, n = 24) in 2-year-old needles. The content of the above mentioned metals in needles of dry coniferous forests (Bs), fresh coniferous forests (Bśw) and humid coniferous forests (Bw) of the ground cover constitute the following decreasing series: Mn(323.8) > Fe(103.4) > Zn(65.5) > Cu(5.9).
Praca przedstawia wyniki badań nad zawartością metali ciężkich w szpilkach Pinus sylvestris wybranych borów sosnowych Słowińskiego Parku Narodowego. Wykazano, iż zawartości metali ciężkich (Zn, Cu, Mn i Fe) w igliwiu były zróżnicowane w zależności od metalu, wieku igliwia oraz wilgotności ekosystemu leśnego. Współczynniki zmienności tych metali utrzymywały się na poziomie: 13–30% (Zn), 3–6% (Cu), 13–34% (Mn) oraz od 12–30% (Fe) w zależności od wieku igliwia. W przypadku Zn, Mn i Fe stwierdzono większe stężenia badanego metalu w igliwiu 2-letnim, niż 1-rocznym, a w przypadku Cu w igliwiu 1-rocznym niż 2-letnim. Wykazano między innymi wzrost koncentracji cynku w igliwiu 1-rocznym (Bw, r = 0,67, p < 0,05, n = 24) oraz igliwiu 2-letnim (Bśw, r = 0,39, p < 0,05, n = 24) wraz ze wzrostem sumy opadów deszczu. Zawartości powyższych metali w igliwiu boru suchego (Bs), boru świeżego (Bśw) i boru wilgotnego (Bw) tworzą następujący szereg malejący: Mn(323,8) > Fe(103,4) > Zn(65,5) > Cu(5,9).

Opis:
In Poland, Anoplotrupes stercorosus (Scriba) and Trypocopris vernalis (L.), are very common throughout the whole country and belong to the most numerous representatives of the Geotrupidae family. Research on the habitat selectivity of Anoplotrupes stercorosus (Scriba) and Trypocopris vernalis (L.) was conducted in the years 2004-2006 in the Wipsowo Forest Inspectorate (Regional Forest Department in Olsztyn). The dung beetles were collected using Barber traps installed in a clear-cut comprising, 2, 3, 5, 8, and 16 year old thickets and tree-stands aged 30, 45, 60, 80, 100 and 135 years. According to phytosociology these tree-stands are a plant community of fresh continental pine forest (Peucedano-Pinetum), while typologically all sites are within the fresh coniferous forest. During the course of this research 29197 individual dung beetles were captured, including 23137 individuals of A. stercorosus and 6060 individuals of T. vernalis. Both species were caught at each research site. At nearly all sites A. stercorosus dominated. Only within the clear-cut area were the number of T. vernalis was higher than at other sites. Very many individuals of T. vernalis were present in the clear-cut area but their numbers decreased gradually with increasing tree-stand age. An opposite situation was noted for A. stercorosus. There was an interesting statistically-significant decrease in the abundance of both species in the middle-aged tree-stands – 30, 45 and 60-year-old. Analyzing the seasonal dynamics revealed one peak in the population of T. vernalis in July, whereas there were two peaks in the population of A. stercorosus: a small peak in July and a much larger peak in September. There was a significant negative correlation between the numbers of T. vernalis and tree-stand age (p<0.05, r =-0.57), and a significant positive correlation between the A. stercorosus population size and tree-stand age (p<0.05, r = 0.48).

Opis:
Structure of 10 Scots pine stands in Nowe Ramuki Forest District was analyzed. The stands were of age from 25 to 220 years. Structure of pine stands younger than 115 years is characterized by low species diversity, low DHB differentiation and regular dispersion of trees. Stands older than 115−135 years show higher species richness, big diameter diversity and random dispersion of trees. Moreover, indices calculated for each stand show higher dispersion in older stands than in younger ones. Structure of old−growth pine stands is similar to natural stands of boreal zone.
