The body size is one of the main attributes of living organisms. The knowledge of body size patterns of co-occurring species and the related factors can contribute to the understanding of many ecological processes. The aim of the study was the analysis of the distribution of the spider species of different size in heterogeneous forest habitats: ground, herbaceous vegetation, tree trunks and leaves. The research was conducted in deciduous stands of the Białowieża Forest (eastern Poland). Spiders were collected by: a) pitfall traps and sieving the litter through an entomological sieve for the ground layer; b) sweep-netting for herbaceous vegetation; c) bark traps for tree trunks and d) shaking the branches of trees and shrubs for leaves. In total, 247 spider species belonging to 22 families were recorded: 195 species in the ground layer, 122 in herbaceous vegetation, 60 on trunks, and 48 on leaves. The analysis revealed that ground layer was inhabited by the small sized species (mean 5.2 ± 0.11 mm) while larger species inhabited herbaceous vegetation (mean 6.6 ± 0.26 mm), trunks (7.2 ± 0.20 mm) and leaves (6.8 ± 0.41 mm). Moreover, the mean species body size decreased with the increasing number of collected species. Several potential mechanisms are discussed as those determining the preference of various sized spider species in particular habitats like different microclimatic conditions, the nutritional quality of prey and predation. Moreover, the very likely reason of differences in the size of spider species between the ground layer and other habitats is the most complex structure of the former habitat.

Many studies have shown that vegetation structure and habitat complexity affect taxonomic composition, functional diversity, and the number of individuals in spider assemblages. These factors also affect spider body size, but mechanisms responsible for that are still not well understood. In our research, we examined the relationship between the body size of spiders from two species – Alopecosa cuneata and A. pulverulenta – and environmental factors such as habitat type and habitat complexity. Our research was conducted in the Bug River Valley on 12 plots covering three types of habitats: mesic meadow, sandy grassland, and xerothermic grassland. Spiders were collected in 2007-08 from April to mid-November using pitfall traps. In total we measured 334 males and 168 females of Alopecosa cuneata and 315 males and 104 females of A. pulverulenta. The generalized linear mixed model revealed that individuals of Alopecosa cuneata as well as A. pulverulenta reached larger sizes in more complex vegetation, whereas the habitat type did not affect the spider body size. One of the likely mechanisms responsible for a larger body size in more complex habitats is predator pressure. Birds as the main predators of spiders, being selective in their choice of prey, may collect larger spiders with higher intensity than smaller ones. We suggest that more complex habitats with dense vegetation provide better shelter for large spiders, which allows them to avoid predators. Our results indicate that habitat complexity may be an important determinant of body size distribution in spider assemblages.

We studied the species richness, diversity, abundance and guild composition of spider assemblages on the hummocks and in the hollows of the alder carr in the Białowieża National Park. We also assessed the effect of vegetation structure and soil humidity on spiders settled in these two microhabitats. The spiders were collected from 10 May until 27 October 2001 by pitfall trapping. The main factor which differed between the hummocks and the hollows was soil humidity. In the case of vegetation cover we found some differences between the microhabitats but it was particularly evident in the case of litter, which was higher on the hummocks. Spider species diversity was significantly higher on the hummocks than in the hollows, but the number of individuals captured in both microhabitats was similar. The collected spiders belonged to six guilds and the proportion of spider individuals in particular guilds was significantly different between the hummocks and the hollows. The most abundant guild in both microhabitats was ‘ground hunters’ and the most numerous species was Piratula hygrophila. Our analyses showed that soil humidity positively affected the number of spider species and the number of individuals. Sampling date strongly influenced the number of collected species and spider individuals. Vegetation and litter cover did not have a significant impact on the spider assemblages. Our findings suggest that research conducted only on hummocks in the alder carr does not reveal the real structure of spider assemblages.

The study was conducted in the Lublin Province, mainly in High Nature Value farmlands along the valleys of the rivers Bug, Tyśmienica and Wieprz. Samples were collected during four years (2012-2015) in study plots located in winter cereals of organic (E) and low-input conventional farming systems (K). Epigeic and epiphytic spiders were caught by using pitfall traps and sweep net, respectively. In Total, 167 individuals from 30 rare and endangered species were collected, which accounted for 0.25% of the totally caught specimens and 13% of all species found. Two species belonged to the category ‘endangered’ (EN) in Poland; 20 species were vulnerable (VU) and seven species with deficient data (DD). The most abundant rare and endangered spider species were by name as follows: Thanatus arenarius, Pardosa maisa and Porrhomma microphthalmum. Statistically significant differences in the number of individuals and the number of rare and endangered spider species, between winter cereals in organic and low-input conventional farming systems were not revealed.

Badania prowadzono w nizinnej części województwa lubelskiego, głównie na terenach rolniczych o wysokiej wartości przyrodniczej wzdłuż dolin rzek: Bug, Tyśmienica i Wieprz. Próby zbierano w ciągu czterech lat (2012-2015) na powierzchniach badawczych zlokalizowanych w zbożach ozimych (żyto, pszenica lub pszenżyto) w systemach gospodarowania ekologicznym (E) i konwencjonalnym o niskiej intensywności (K). Pająki naziemne (epigeiczne) chwytano przy pomocy pułapek Barbera, natomiast pająki naroślinne (epifityczne) przy pomocy czerpaka entomologicznego. Złowiono 168 osobników z 30 gatunków rzadkich i zagrożonych, co stanowiło 0,25% wszystkich zebranych osobników i 13% wszystkich stwierdzonych gatunków. Dwa gatunki należały do grupy silnie zagrożonych wyginięciem (EN – Endangered); 20 gatunków należało do narażonych na wyginięcie (VU – Vulnerable) i siedem gatunków o nieokreślonym zagrożeniu (DD – Data Deficient). Najliczniejsze spośród gatunków rzadkich i zagrożonych były następujące pająki: Thanatus arenarius, Pardosa maisa oraz Porrhomma microphthalmum. Nie stwierdzono statystycznie istotnych różnic pomiędzy liczbą osobników i liczbą gatunków rzadkich i zagrożonych pająków w zbożach w systemie ekologicznym i konwencjonalnym o niskiej intensywności.

Species – area (SAR) and species time (STR) relationships describe the increase of species richness with study area and study time and have received much attention among ecologists and are used in different branches of biodiversity research. Unknown sample size effects often hinder a direct comparison of SAR and STR shapes of different taxa and regions. Further, space and time interact during the accumulation of species due to the common sample universe. Here we develop a simple power function scaling model of species richness that integrates space, time, sample size and their interactions. We show that this model is able to precisely describe average species densities and the increase of species richness in a regional metacommunity of a large sample of spiders on Mazurian lake islands (Northern Poland). The model predicts strong area – sample size and time – sample size interactions. Judged from the SAR (z = 0.08) and STR (y = 0.64) slopes it points to only moderate spatial β-diversities but high local temporal species turnover. We suspect that the parameters of many published SARs are strongly influenced by unknown sampling time and sample size effects that make direct comparison difficult.

Data on the density and the body mass of a single community of soil fauna were collected and metabolic rates were calculated from the literature data to test some predictions of the metabolic theory of ecology on the local scale. Part of the results are in accordance with the theory: power functions were found between the metabolic rate and the body mass, and between the density and the body mass. These two relationships have opposite exponents inducing that total population energy use is independent of the body mass. However, the exponents of the relationships were significantly different from the predicted values of |3/4|. The metabolic rate - body mass relationships yielded an exponent >0.8, while the density - body mass relationships yielded an exponent <-0.85. Our results indicate that the metabolic theory of ecology does not hold at the local level. Few studies have been carried out on the local scale and further analysis is required to validate this controversial but promising theory.
