Abstract

Original data on Cladocera fauna in water bodies and watercourses of mire ecosystems have been obtained for the first time in Kaliningrad oblast during the study conducted in large raised bogs (Zehlau and Bolshoye) and drainage canals of six peatlands affected by peat extraction. In the studied wetland ecosystems, 41 species of Cladocera are recorded in total, including a number of rare and vulnerable taxa (Flavalona rustica, Scapholeberis microcephala, Streblocerus serricaudatus, and Holopedium gibberum). The four species of Cladocera are new for Kaliningrad oblast. Cladocera plays a key role in the studied bog pools and waterlogged habitats in peatlands as a key group of organisms that forms here a significant part of the zooplankton biomass due to the abundance and intensive production in the water bodies. The secondary filter feeders and predators are the most abundant in bog ecosystems. The cladoceran fauna in the intact bog ecosystems, especially the Zehlau raised bog, is the most diverse and unique. Nevertheless, the cladoceran assemblages in the disturbed ecosystems of drainage canals retain certain features of the natural water bodies. The latter fact is important in the applied respect, making it possible to consider these canals refugia that have potentials for the natural restoration of the cladoceran fauna during the peatland rewetting program on the Carbon Supersite in the Kaliningrad region.

关于泥沼生态系统中枝角类（甲壳纲：鳃足纲）物种组成和发育的第一批数据（俄罗斯加里宁格勒州）

摘要

在加里宁格勒州，在受泥炭开采影响的大型沼泽（Zehlau 和 Bolshoye）和六个泥炭地的排水渠中进行的研究中，首次获得了加里宁格勒州沼泽生态系统水体和水道中枝角动物群的原始数据。在所研究的湿地生态系统中，总共记录了41种枝角类动物，包括一些稀有和脆弱的类群（黄黄花、小头藻、 链锯藻和赤花藻）。这四种枝角类动物对于加里宁格勒州来说是新物种。枝角类在所研究的泥炭地沼泽池和淹水生境中发挥着关键作用，作为一个关键的生物群，由于水体中的丰富性和集约化生产，枝角类形成了浮游动物生物量的重要组成部分。沼泽生态系统中的次级滤食性动物和捕食性动物最为丰富。完整的沼泽生态系统中的枝角类动物群，特别是泽劳沼泽沼泽，是最多样化和独特的。然而，受干扰的排水渠生态系统中的枝角动物组合保留了天然水体的某些特征。后一个事实在应用方面很重要，使得可以在加里宁格勒地区碳超级站点的泥炭地再润湿计划期间考虑这些运河保护区，这些保护区有可能使枝角类动物群自然恢复。
