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.

Opis:
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:
The research on ground beetle assemblages was carried out in the virgin forests of the Białowieża Primeval Forest and in managed forests. Ground beetle assemblages in restocked cutting areas were characterized by lower values of the indicators characterizing the state of their successional development: MIB and SCP, participation of relict and wingless species. No differences in the number of species harvested in virgin forests and regenerated stands were confirmed.

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.
