Stammbewohnende Weberknechte (Arachnida: Opiliones) in einem Fichten- einem Misch- und einem Buchenbestand im Solling

Abstract

In the Solling mountains (Southern Lower Saxony, Germany) the fauna was sampled for one year with stem eclectors in adjacent spruce, mixed (spruce/beech), and beech stands. The tree age was more than 90 years. Four sampling treatments were established: eclectors on spruce stems in the spruce stand (1), on beech stems in the beech stand (2), and on spruce (3) and beech stems in the mixed stand (4). The following harvestmen species, with 1601 individuals in total, were found: Mitopus morio, Oligolophus tridens, Platybunus bucephalus, Leiobunum blackwalli, and Leiobunum rotundum. The number of individuals was highest on spruce stems in the more open spruce stand, mainly due to Mitopus morio, whereas number of species was highest on beech stems in the mixed stand. Both the number of individuals and species were lowest on beech stems in the beech stand. Here, additional information about the phenology of the harvestmen species is given.
