The species composition, abundance, and isotopic signature of millipedes (Myriapoda, Diplopoda) were investigated in seven biotopes of Kaluzhskie Zaseki State Nature Reserve. Nine Diplopoda species were found in total, and the local species diversity (within a sampling plot) reached seven species. The Diplopoda tissues were similar to the plant litter in the isotopic composition of nitrogen (delta15N was by 0.4% per hundred higher, on average), but were more strongly enriched in heavy carbon (delta13C was by 4% per hundred higher, on average). Removal of mineral carbon from the cuticle reduced delta13C of Diplopoda by about 1.4% per hundred on average. Differences in the delta15N and delta13C values between the species did not exceed 2.5 per hundred. Differences in the isotopic compositions of the considered species are insignificant, and thus, it is impossible to distinguish particular trophic guilds in the Diplopoda community. Analysis of the published data confirmed that isotopic differentiation of millipedes was much less pronounced than in other investigated groups of soil animals. Hence, millipedes of the deciduous forest form a uniform trophic group.
在卡卢日斯基扎谢基国家自然保护区的七个生物群落中，对千足虫（多足纲，倍足纲）的物种组成、丰度和同位素特征进行了调查。总共发现了9种倍足纲物种，当地物种多样性（在一个采样区内）达到了7种。倍足纲动物组织在氮的同位素组成上与植物凋落物相似（平均而言，δ15N每百比高0.4%），但在重碳方面富集程度更高（平均而言，δ13C每百比高4%）。从角质层去除矿物碳后，倍足纲动物的δ13C平均降低了约每百比1.4%。物种之间δ15N和δ13C值的差异不超过每百比2.5。所考虑物种的同位素组成差异不显著，因此，不可能在倍足纲动物群落中区分出特定的营养类群。对已发表数据的分析证实，千足虫的同位素分化比其他调查的土壤动物类群要小得多。因此，落叶林的千足虫形成了一个统一的营养群体。
