Spider collection of the Prioksko-Terrasnyi Biosphere Reserve

The database is a result of two-year investigation of the spider communities in nine different habitats in the Prioksko-Terrasnyi Biosphere Reserve, located in the south of the Moscow Region. The Reserve is characterized by the compound landscape, including the boreal, nemoralis, and steppe components. In particular, the “Oka flora” is a unique phenomenon evolved in the Oka river valley. Within the Forest Zone, the small steppe patches (about 1.5 ha) are situated, where grow typical steppe plants (feather-grass, fescue, etc.) separated from their main habitats by many hundreds of kilometers to the north. The place is considered to be the most northern locality of steppe plants on the Central Russian Upland. In total, 246 spider species from 23 families and 129 genera were recorded during the study.

该数据库源于对位于莫斯科地区南部、占地广阔的普里奥克斯科-捷拉斯尼伊生物圈保护区九个不同生境中的蜘蛛群落进行的为期两年的深入调研。保护区以其复合景观而著称，包括北方针叶林、温带落叶林和草原等不同生态系统的组成部分。特别是，‘奥卡植物群’是奥卡河谷中演化出的独特现象。在森林区域中，分布着约1.5公顷的小型草原斑块，其中生长着典型的草原植物（如羽毛草、狐茅等），这些植物与它们主要栖息地相隔数百公里，向北延伸。此地被认为是中央俄罗斯高地草原植物最北部的分布地。在研究过程中，共记录了来自23个科、129个属的246种蜘蛛。
