The is insufficient knowledge of arthropod communities occurring in specific microhabitats. In this study, we characterize the arthropod assemblages inhabiting burrows of the common hamster (Cricetus cricetus L.) and factors that determine their diversity and abundance. We tested the following hypotheses: (1) arthropod assemblages are associated with a particular dominant vegetation occurring in the vicinity of burrows; (2) a correlation exists between fine-scale geographic distances among burrows and assemblage dissimilarity; and (3) the type of trap influences the sampling success of captured arthropods. We found 73 morphospecies belonging to 16 families in 109 burrows, most of which were in the families Staphylinidae (Coleoptera) and Parasitidae (Arachnida: Acari: Mesostigmata). The most abundant families were Staphylinidae, Cryptophagidae (Coleoptera), Parasitidae, and Macrochelidae (Mesostigmata) (78.89%). Among the identified species, we found Aleochara irmgardis (Staphylinidae) and Poecilochirus sexclavatus (Parasitidae) which had not yet been reported in Poland, and several other rare species. Meat-baited traps captured 64.34% more individuals, which were more diverse and species-rich than the non-baited control traps, but the former was more selective for saprophages, necrophages, and coprophages. The burrows located in areas overgrown by triticale (a hybrid of wheat and rye) were inhabited by 69.86% of the identified arthropod species, and these also had the highest abundance (64.07%) in comparison with other habitats. However, differences in sample size biased our results toward and overestimate arthropods associated with this vegetation. This study underlines that the species composition detected in burrows was affected by the methods used and hamster preferences for a specific habitat rather than the geographic proximity of the burrows. More extensive sampling across multiple habitats will be necessary to confirm our findings.
我们对特定微生境中节肢动物群落的了解不足。在本研究中，我们描述了栖息于普通仓鼠（Cricetus cricetus L.）洞穴中的节肢动物群落以及决定其多样性和丰度的因素。我们检验了以下假设：（1）节肢动物群落与洞穴附近出现的特定优势植被有关；（2）洞穴之间的精细地理距离与群落差异之间存在相关性；（3）诱捕器的类型会影响捕获节肢动物的采样成功率。我们在109个洞穴中发现了属于16个科的73个形态种，其中大多数属于隐翅虫科（鞘翅目）和寄螨科（蛛形纲：蜱螨亚纲：中气门目）。数量最多的科是隐翅虫科、隐食甲科（鞘翅目）、寄螨科和巨螯螨科（中气门目）（78.89%）。在已鉴定的物种中，我们发现了在波兰尚未有报道的伊尔姆加德隐翅虫（隐翅虫科）和六棒禽刺螨（寄螨科），以及其他几种稀有物种
