Opis:
The colonisation and movement of ground beetles on a cutting area with two retained old−growth clumps of 4 and 7 are were investigated using the CMR method. The method enabled to evaluate the trapping level of small non−forest species. The paper discusses the use of old−growth clumps during the colonisation of the cutting area by big forest species and concurrent "avoidance" of these areas by small non−forest species. Stimulating role of the parallel and perpendicular ploughing furrows in the process of the colonisation the cutting area by forest and non−forest species as well as differences in their perception of site micro−differences were also analysed. The results confirmed assumed hypothesis in case of non−forest species (avoidance of clumps), forest species C. arcensis and non−forest species P. caerulescens and individuals from the genera Amara and Harpalus as far as the influence of furrows is concerned. Differences in the perception of the cutting area between forest and non−forest species were also proved.

Opis:
The catch rate and body length of Anoplotrupes stercorosus and Trypocopris vernalis were studied in 2018 on permanent plots established in 2003 in Scots pine stands left for spontaneous succession in the Piska Forest (N Poland). The plots comprised treatment A – severely disturbed stands (canopy cover of 10−30%), treatment B – moderately disturbed stands (canopy cover of 40−60%) and treatment C – the least disturbed stands in which all or nearly all trees survived (canopy cover of 70−90%). Each treatment class was replicated six times. In addition, we included a Scots pine plantation established in 2006 after the soil preparation as a stand in the earliest phase of succession. The following hypotheses were set: (1) severity of stand disturbance affects the body size of both species and (2) in the surviving remnants of stands (later phase of succession development) the body length of both species is greater than in disturbed stands and in the young plantation. No differences between the catch rate of both species in different treatments was detected (tab. 1 and 2). However we found significantly longer body of T. vernalis. The increase in the difference between the length of both species in the least disturbed stands as well as in the late stages of stand development was found (fig. 1 and 2). The direct effect of the LAI and inversely proportional effect of soil temperature on the catch rate and length of the body of A. stercorosus and, to a lesser extent, T. vernalis were observed (fig. 1). The high catch rate of A. stercorosus and the length of its body was linked with the soil covered only with forest litter (which occurs in dense stands with a high LAI index) (fig. 2). The catch rate of T. vernalis was correlated with the predominant nitrophilous Deschampsia fexuosa, which suggests the preferential occurrence of T. vernalis in ‘open’ stands with a high level of solar radiation. In turn, the length of T. vernalis body correlated with a high proportion of Calluna vulgaris, which may suggest a dependence of this parameter on light reaching the soil. The above observations indicate that in the production cycle of Scots pine stands, T. vernalis prefers open stands (especially clear−cuts, young plantations), while A. stercorosus is more often met in dense stands. The catch rate of both species is not suitable for zooindication research, while the length of their body is suitable. The higher the stage of ecological successive of the pine stand, the greater the difference in the body length of these species.

Opis:
In this paper the effect of different methods of soil scarification in a clear−cut area were studied. The following soil preparation techniques were applied: the soil cutter, the active soil plough, the traditional method with use of LPz plough, and the manual scarification of soil in circles surrounding the stem of the future young tree. The effect of management of the residual heaps of branches was also tested. Branches were either put in prisms in the original shape or, having been previously chipped, equally distributed over the entire area of the clear−cut. Additional studies focused on the effect of the time of clear−cut execution (winter or summer) on the condition of epigeic carabid communities. The least regressive effect to analysed communities was observed after the application of the point manual soil scarification. The clear−cuts carried out during the winter season, to a greater degree, favours the forest carabid fauna, preserving them in a structure more resembling the forest communities. More distinctive positive effect on the carabids is observed after putting the residual heaps of branches in prisms; the latter gives shelter for the carabid fauna and constitutes the refuge spots for it.

Soil respiration and organic matter decomposition in the soil prepared by four different methods was investigated. Soil was prepared with the cutter, active plough, deep furrowing (strips) plough and manual disk ploughing on areas felled in summer or winter, with and without retained branch piles, as well as in the clumps of old−growth and young−growth stands. The soil respiration rate increased following stand removal, while it was reduced after soil preparation process. The highest CO2 respiration and organic matter decomposition were noted in the variants with the soil cutter or manual disk plough, while the lowest – in the variant with deep furrowing (strips) plough.

Opis:
The experiment analysed magnitude and structure of invertebrate fauna caught in different empty bottles and cans left by tourists in the four different forest ecosystems. Empty boxes that previously had contained several types of beverage (mineral water, apple juice, bread derived dark brown beverage, coke and beer) were installed. Each bottle was repeated three times. They were subsequently examined on three occasions for invertebrates every two weeks. A total of 1069 specimens belonging to 27 species or taxa were captured. The highest catchability was recorded in fresh mixed coniferous forest. The presence of saprophagous and predatory species in the emptied beverage boxes suggests the establishment of detritus trophic chains. The species composition similarity of invertebrates captured in the empty bottles depended on the site fertility and, only to a minor degree, on the type of beverage. The PCA showed that another factor influential in the species composition of captured fauna was the degree of transparency of the box. The dominant species was A. sterocorosus; this beetle was most frequently captured in the mixed coniferous forest type. The experiment showed very high danger for the forest invertebrate fauna from the side of empty bottles left by tourists.

Opis:
Turystyka wodna oddziaływuje zarówno na ekosystem jeziora, jak i na ekosystem leśny na jego brzegu. Oddziaływania te mają charakter fizyczny, chemiczny oraz biologiczny. Ze względu na akumulację ich skutków oraz wzrost presji, oddziaływania te mają charakter jednokierunkowy. Efektem tego działania jest powstawanie zubożonych ekosystemów leśnych, oraz bardzo silna eutrofizacja jezior. Możliwości poprawy w przyszłości stanu ekosystemów leśno-jeziornych, choć kryją się w rozwiązaniach prawnych, jednak przede wszystkim znaleźć się powinny w odpowiednio prowadzonej edukacji od najmłodszych lat oraz w systemie szkolenia na stopień żeglarza.
Summaries of the main physical, chemical and biological impacts on aquatic and riparian ecosystem by water tourism as well land tourism are presented. Due to accumulation of results of tourism impact on ecosystem this impact has one-way direction of action. Possibility of improvement of the state of ecosystems should be found not only in law regulation but mainly in education, especially in schools.

Opis:
Carabidae were used as a zooindicator to evaluate different soil preparation techniques applied to farmland prior to afforestation: full deep ploughing (MBS), full ploughing to a depth of 25 cm using agricultural tractor (OR), full ploughing to a depth of 25 cm with subsoil ploughing (ORP) and raising of soil horizons A0 and A1 (NW). The studies were conducted 4 and 5 years after afforestation. The total number of caught beetles was 13 869 individuals from 68 species. Taking into consideration the trapping ability, mean individual biomass and colonization by xerophylous or forest species the deep ploughing BMS and subsoil ploughing ORP was found to have the greatest impact on the carabid recolonisation rate and site degradation.

Opis:
The trapping of weevils on cutting areas using different soil preparation methods was tested. A soil cutter mixing mineral soil with humus best stimulated the weevil trapping. The methods connected with breaking up the humus layer: manual disk ploughing or using an active plough and ploughing with deep furrowing (strips) stimulated weevil trapping to the smallest degree. The piles of branches on the felled areas had no effect on the increase of weevil trapping, while the winter felling, unlike the summer one, increased the trapping level. On the basis of the results obtained in the study the specified methods to improve the cutting management were proposed.

Opis:
During the period from 2003 to 2011 observations of carabid community regression and selected habitat indicators were conducted on 15 plots in stands that had been disturbed by a hurricane and on 15 plots in control stands. Regression of carabid communities delayed 3−4 years was observed, consisting in increases in the number of species and the proportion of xerophilous species and reductions in the percentage of forest fauna and in mean individual biomass. Only after 7 years did these indicators begin to show a tendency in the reverse direction, albeit not very strong, indicating that carabid communities had begun to regenerate.

Opis:
Nearly 27 000 individuals of 10 species belonging to the Carabus genus were caught on over 160 research plots in 13 different habitats in the Białowieża Primeval Forest, Poland. The body length of eight species was analysed. The mean body length ratio of two adjacent species ranged between 1.00−1.10, irrespective of the number of the number of Carabus species in the assemblage. The mean ratio of the smallest to the largest species increased with the number of species in the assemblage. To study coexistence mechanisms further, automatic traps were used to catch carabid beetles in decaying stumps and tree holes. In tree holes, the species C. hortensis was caught in the greatest numbers. Morphological differences and ecological preferences suggest spatio−temporal niche partitioning as the main coexistence mechanism for Carabus species in this forest.

In the paper attention is given to the occurrence of carabid beetles in the environment of fallen decaying trees and hollows of standing trees. The catches of carabids in these environments are on the level of 1/6 of the catching efficiency of Barber's traps, which emphasizes the importance of such environments for epigeic carabid beetles. The paper discuses the causes of carabids to visit trees, as well as differences in their activity when on trees resulting from differences in anatomy of legs of these insects.

Opis:
Exceedingly violent winds can result in windbreak and in windthrow. It has happened in summer of 2002 in Pisz Forest District (north part of Poland). Strong wind damaged about 30 000 hectares of pine forest. In most situations, damaging wind resulted in windthrow rather than windbreak. In total 30 plots were selected for the studies, 15 plots in Pisz forest (damaged by wind) and 15 control plots in Maskulińskie District Forest (not damaged by wind). There were distinguished 5 age variants of stands, all of them in three recapitulations. The five age classes of stands were: I class (20−30 years old), II class (30−40 y.), III class (40−50 y.), IV class (50−70 y.) and V class (above 70 years old). In total 4 000 carabids individuals belonging to 46 species were caught during studies. The wards analy− sis showed substantial diference of carabid assemblages occurring in damaged and non damaged forest. In damaged forest, small zoophages, hemizoophages, an open area or eurtyopic species, xerophilus species were frequently observed. Substantial differences in mean individual biomass of assemblages occurring in damaged and non damaged forest were also observed.

Opis:
The objective of the article is to present different types of tourist routes and infrastructure elements preferred by the society basing on the results of the nationwide survey, which was conducted in 2013 on a representative sample of 1000 individuals over the age of 18. The sample was of random−amount character. Respondents evaluated the usability of several types of tourist objects (routes and paths) as well as different devices constituting their equipment. The survey also included the question which allowed the evaluation of usability of 10 infrastructure elements, which increase the quality of leisure in forests. Statistical analyses included General Line Model (GLM) or ANOVA and post−hoc comparisons with Tukey HSD test. In case of equivocal results of analyses, data was retested with PCA, which was selected upon checking the length of gradient with DCA. Data was analyzed with regard to the respondents' age, education and material status. The most desirable routes turned out to be walking trails and hiking routes (fig. 1). Results indicate that the most useful infrastructure objects include waste bins and information boards, while the least usable are playsets for children and fitness equipment (fig. 4). The most useful infrastructure elements are: signs and then ex aequo: car parks, places for animal observation, rest facilities and viewpoints, and the least needed: children's playgrounds, rope parks, and paintball sites.

Opis:
The study included 15 isolated islands, grouped in five size classes. Trapped individuals were identified to species and measured and weighted. The number of carabid species was higher in the ecotone zones as compared with the island interior. Reduction in total number of carabid species was observed with increasing size of an island. The share of forest related carabid species was positively correlated with the size of an island; similar was the pattern concerning the large zoophages, the European and brachypterous species. The larger an island, the higher value of the mean individual biomass index (SBO) and the index of Progressive Features Sum (SCP). With the growing size of the islands, the carabid communities are placed still further to the uppermost right hand corner in the SCP/SBO diagram (fig. 2). Response of carabid communities to different size forest islands has shown that the smallest islands which favor the establishment of stable forest communities are 0.63 ha. Hence, it is to consider in the practice of forest management to create islands not smaller than that area (this may be established at the level of about 1 ha, for the practical purposes).

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:
Driven by social and economic changes, which have taken place for the last 30 years, the European forest management objectives have been redefined. By the action of public opinion, forest management, increasingly frequently and in a broader range, focuses on public benefits from forests. One of the most important functions is the possibility of leisure and recreation in the forest. The purpose of the research was the analysis of the hypothetical readiness to finance the leisure−related function of forest based on WTP (Willingness To Pay) amount. A question, which enabled the assessment of a social value of leisure−related function of forest, was asked to a random−quota sample of 1000 people over 18 years of age during the nationwide survey carried out in 2013 by TNS Polska. Out of 1000 respondents, the WTP>0 was declared by 29% respondents. Surveyed persons indicating forest with poorer infrastructure declared higher values calculated per household (PLN 13.59 ±0.84) than respondents who selected a better managed forest (PLN 12.86 ±0.88, PLN 12.91 ±1.46). The average WTP amount per person for respondents with the university degree (bachelor and master degree) was PLN 6.23 ±0.48, whereas for respondents with lower education, it was on the level of PLN 5.26 ±0.25. The average WTP also depended on the age of respondents. It was PLN 11.42 ±1.43 for 20−year−olds per family, whereas for 40−year−olds it was PLN 14.16 ±1.05. The average WTP per person increased along with the age of respondents; from PLN 4.37 ±0,42 (20−year−olds) to PLN 6.00 ±1.11 (80−year−olds). Disregarding the top WTP value per household of respondents in the worst financial situation (20.00 ±10.00), the average WTP value per household increased from PLN 10.26 ±1.69 (in poor financial situation) to PLN 14.55 ±2.97 (very well−off).

Opis:
Changes in structure of carabid assemblages caused by tourism were observed. They turned to be smaller in comparison to those caused by clear−cuttings, which was demonstrated on the example of selected indices (SCP, SBO) and SCP/SBO model analysis. Increase in regression changes in carabid assemblages with the increase of the pressure from water−tourists was shown. It was demonstrated on the basis of reduction of the frequency of autumn species, increase of the number of small zoophages and replacement of the higrophilous species with mezophilous ones. Higher pressure resulted in higher standardised number of species as well. However, achieved results suggest that changes in the environment are not so heavy, they are important for forest economy.

Opis:
The effect of late cleanings and early thinnings on carabid assemblages in a stand was established one year and three years following the treatment. Cuttings have caused changes in the composition of the main carabid species. The number of the representatives of the xerophilous, Palaearctic and Holarctic species has declined while the share of individuals of the autumn development type and of forest species has increased. Following the cuttings the SCP index and the Mean Individual Biomass have attained higher values. The results suggest that tending cuttings in the stand have a favourable effect on the carabid assemblages.

Opis:
During winter time, beetle individuals were collected from soil samples taken from a Scots pine culture, an old−growth Scots pine forest, and a European larch culture and old−growth. The following research questions were put forward: (1) Does an admixture of larch in the forest stand contribute to increase in species diversity as well as the numbers of beetle individuals hibernating in the forest litter? (2) Does an admixture of larch in the forest stand result in an increased proportion of beetle species – potentially pests for the forest trees, in the carabid communities? We analyzed data with use PCA, Ward method. The first question should be answered positively. The second question should be answered negatively. The analyses of beetle fauna overwintering in the forest litter as carried out in this paper confirmed the purposefulness of larch introduction as an admixture in pine stands in Lithuania.

Opis:
The paper presents the results of a three−year research on ground beetle (Carabidae) assemblages conducted in the stands of the Piska Primeval Forest damaged by the 2002 hurricane and in control stands. Observations were carried out in the stands categorised into 5 age classes: class I (20−40 years), class II (40−50 years), class III (50−60 years), class IV (60−70 years) and class V (over 70 years). Beetles were caught using modified Barber's traps. The soil CO2 efflux rate and C:N ratio were measured. The Ward cluster analysis and Canonical Correspondence Analysis (CCA) clearly distinguished between carabid assemblages in the stands damaged by the hurricane and control stands. In damaged stands there was an increase in the number of Carabidae species with the simultaneous decrease in their abundance. The proportion of forest and European species has been considerably reduced. A marked decline in abundance of hygrophilous species in favour of xerophylous ones was also noted. The observed reduction in the SPC (Sum of Progressive Characteristics) index may indicate the preservation of changes in carabid assemblages and that their regeneration has not yet started.

Intraspecific differentiation in body size was investigated for Carabus arcensis, C. violaceus and Pterostichus niger populations inhabiting pine forests disturbed by the hurricane and non−disturbed ones. Post−hurri−cane stands were localized in Szast Reference Forest (Pisz Forest District, NE Poland) disturbed by the hurricane in July 2002 and left "untouched" as an experimental area. Non−affected stands were set in Maskulińskie Forest District (NE Poland). Beetles were sampled using pitfall traps. The hurricane contributed to significant reduction in both C. arcensis and C. violaceus body length. However, an opposite trend was observed for P. niger, which increased considerably in body size in disturbed stands compared to control ones. The most pronounced changes were observed in 2007. Differences in habitat preferences and food resources utilization of C. arcensis, C. violaceus and P. niger are discussed.

Opis:
Studies on invertebrates in the diet of the tawny owl were carried out in Rogów, Kampinos and Białowieża forests as well as in the mosaic ecosystems of Biebrza wetlands. Invertebrates were identified on the basis of their remnants found in the pellets. The aim of the study was to answer the two questions: (1) does the tawny owl select its invertebrate prey or is it an opportunist predator, (2) is it possible to characterize places where the owl preys just on the basis of the invertebrate species composition in its diet. As a result we found out that indeed the tawny owl was an opportunist predator towards invertebrates, and also that the invertebrate species composition found in the pellets was a good indicator of the type of hunting habitat as it showed that the owl caught invertebrates in various sites, i.e. tree hollows, rotten trunks, soil litter or open area.

Opis:
The objective of the paper is to analyse the social preferences to the type of the forest stand and factors deciding about the tourist attractiveness of the forest. Data was collected during the nationwide surveys carried out in 2013 on the random representative sample of 1000 respondents above 18 years of age. The surveyed persons do not indicate strong preferences for deciduous or coniferous forest stands. The analysis of preferences for different types of forest stands with regard to respondents' sex did not confirm the importance of differences. Instead they suggest that respondents of different age tend to change their preferences with time – from broadleaved forest (the youngest respondents) to coniferous forest. Respondents in poor financial standing choose deciduous forest and mixed broadleaved forest, and people in good and very good financial standing – a coniferous forest stand, or rather a mixed one. What makes a forest stand attractive is mostly the forest's appearance and the nature along with the abundance of species, and the least, the presence of water or culture and historic sites. The older the respondents are, the more they appreciate silence and relaxation far from other people, as well as nature along with its abundance of fruits and fungi to be collected, while the least important is the diversity of land. Respondents with higher education (university degree) indicate the availability of land and the presence of waters as the most important features which decide of the attractiveness of forest, whereas people with the lowest education level – nature along with its abundance of species and the forest appearance. Respondents, who are in the best financial situation declare the appearance and the presence of lakes and rivers (features related to leisure), to be the most important factors which decide about tourist attractiveness of forest, and people in poor and very poor financial situation indicated: nature along with the abundance of species, availability of forest, places related to culture and religion, nature reserves, and tourist infrastructure.

Opis:
A survey on the structure and species composition of ground beetle assemblages inhabiting forest stands disturbed by the hurricane was carried out. During the first 6 years after the hurricane two distinct phases of carabids response to the disturbance could be observed. The first 3 years were characterised by relatively minor, although mostly statistically significant changes in carabids abundance, mean individual biomass and assemblages structure. In the 4th year after the hurricane, the second phase started comprising profound changes in all analysed parameters. The state of development of ground beetle assemblages inhabiting disturbed stands worsened considerably, however it did not reach the very low level recorded in assemblages inhabiting clear−cuts. The study revealed that the regression of carabid assemblages in post−hurricane stands occurred with a time lag of 3 years after the hurricane. Moreover, no symptoms of carabid assemblages regeneration could be observed.

transforming managed forest into reserve
SIMPER analysis
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 aim of this study was to recognize the threats to waterside stands and their ecotones growing on the banks of the Bełdany Lake heavily utilised by tourists. The method applied included of stand and bank inspection along 33 300 m of the shoreline, as well as polling tourists. The signs of damage caused by tourists were found every 330 meters of the shoreline, on average. The reed belt was most threatened. The places of its depletion can be spotted every 450 meters. Also waterside stands are exposed to penetration. A belt of 50 m or more in width is penetrated by about 60% tourists. The damage caused consist of soil compaction, disappearance of natural herb layer species, harvesting of wood for making fires, damage to trees, leaving litter in forests, or making fires.

Opis:
The study tested the following hypotheses: the mortality of invertebrate fauna is higher (1) on wide trails than on narrow ones, (2) on sections near the entrance to the forest than on the parts located within the forest, and (3) during the weekend than during the workdays. To assess the mortality of epigeic fauna trampled on hiking trails, the most frequented trails in the Chojnów Forest District (central Poland) were selected. On each trail, 100 m long segments were designated near the boundary with open terrain (‘entrance' sections) and inside the forest, 500 m from the edge. Paths wide less than 1.5 m were considered as narrow, while those wider than 3 m as wide ones. Data was collected in 2016 and 2017 (8 and 7 inspections, respectively). A total of 752 trampled animals belonging to 25 species or taxa were found. GLM analysis did not reveal significant differences between the number specimens or species trampled on trails with different location or width. However there were more dead individuals and species on the entrance segments. Also, more dead specimens and species were found on wider paths, but the difference was not significant (fig. 1, tab.). The number of trampled invertebrates increased significantly during the weekend (fig. 2, tab.). NMDS clearly ordered the data from fauna collected at the entrance trails to those collected within the forest (fig. 3). 74.9% of the variation in species data was explained by the first PCA axis and 14.0% by the second one. The first axis was associated with the trail location (fig. 4). Points representing invertebrate fauna found on narrow paths (especially inside the forest stand) are located closer together than points representing fauna on wide trails (especially those bordering on open areas). The PCA correlated the most significant trampling of the dor beetle (A. stercorosus) with narrow trails within the stand and trampling of the spring dor beetle (T. vernalis) with wide paths near the entrance. The impact of hiking on the forest and all of its fauna is still little known. In order to effectively counteract its negative effects and protect organisms present on trails, research should be continued.

Opis:
Spontaneous regeneration in the hurricane−disturbed stand in the Pisz Forest District (N Poland) was registered in the years 2007−2008 and 2011−2012. Breast height diameter and crown size were measured on 10×10 m plots. The analysis also included the soil respiration rate, the decomposition rate of organic matter, soil pH, leaf area index (LAI), content of Mg, Ca, C, N and P in soil, and vegetation coverage of the forest floor. The natural regeneration was dominated by birch, followed by pine, which recolonized the disturbed stand in smaller extend, possibly because of the thick cover of organic material hindering germination and making it difficult for pine sprouts to reach the mineral soil. Spontaneous regeneration of the stand was most severely inhibited by Deschampsia flexuosa, whose growth over the entire surface was linked to the capture of excess released nitrogen resulting from the decomposition of organic matter. Mosses and lingonberry did not delay the spontaneous appearance of seedlings. The development of the natural regeneration suggests the possibility that an uneven−aged stand will emerge.

Opis:
Questionnaire surveys were conducted from July 1st to August 15th, 2012 in forests near Gołdap, Białowieża, Pisz, Kraoenik, Warsaw and Zakopane with 335 respondents – 146 residents (43.6%) and 189 tourists (56.4%). The respondents declared that they visit forests throughout the year for various purposes, most often with family or friends and most frequently for the recreational activity of walking. They typically spend about three hours in the forest during a single visit. Respondents perceived the most important functions of the forest as a place where plants and animals live, as well as a place for recreation. In their view, the state budget should be a source of co-financing the recreational management of the forest. Only a small number of respondents (27.5%) would be willing to allocate a portion of their income for recreational forest management. According to the respondents, the most important elements needed in the forest to improve its quality for tourism are information signs and litter bins. Respondents perceive the greatest threats to the forest from tourism to be vandalism, automobiles driving into the forest and wildlife disturbance, whereas the greatest threats to tourists were reported to be biting and stinging animals (snakes, ticks and mosquitoes) and the possibility of getting lost. Respondents indicated clean air, peace and quiet, as well as the ability to harvest wild fruits, plants and mushrooms as the greatest advantages of using the forest for recreation. A large proportion of respondents admitted that they would like to use the services of professional foresters, especially for nature walks and health related purposes, as well as to educate children and youth about nature and the forest.

Opis:
The impact of narrow (up to 2 m), medium (up to 3.5 m) and wide (>3.5 m) tourist trails on the surrounding environment was investigated. On wide trails, the value of soil erosion and compaction indices was found to be the highest, while the herb height index was the lowest indicating the greatest impact of wide trails on the environment. The phytosociological relevés were used to determine ecological indicator figures. Wide trails were characterized by higher thermal and continentalism indices and lower pH and trophic indices. The proportion of therophytes and geophytes was higher, while of hemicryptophytes, phanerophytes and chamaephytes on wide trails were lower than on medium and narrow trails. All the analysed indices pointed to a stronger impact of wide trails on the environment in comparison with medium and narrow trails.

Opis:
The folding of knotted proteins remains a mystery both for theoreticians and experimentalists. Despite the development of new models, the driving force for self-tying remains elusive and the principle of minimal frustration cannot be reproduced in silico. In this paper we review different models used to understand protein self-knotting and suggest, how to improve the structure based model to observe efficient folding. Our preliminary results show, that including information about some amino acids properties, or reducing the set of physical contacts may be beneficial for modeling of the knotted protein folding.
