Tree species and microhabitat affect forest bog spider fauna

Abstract Peat bogs are among the most threatened habitats in Central Europe. They characterized by stagnant water with low pH and lower nutrient content compared to surrounding habitats. The flora fauna of peat comprised many habitat specialist rare species. We explored differences spider European spruce Scots pine forests. Furthermore, we assessed effect microhabitat diversity bog forests Poiana Stampei complex, Bucovina, Romania. collected numerous cold-adapted .We found a strong forest type, presumably due different microclimatic conditions had species richness ground-dwelling than forests; however, contradictory results for vegetation-dwelling richness. Hummocks more positive on spiders forests, open structure sphagnum hummocks ground level. However, this was negative vegetation dwellers. restricted ranges vulnerable climate change, may serve as important micro-refugia them. isolated highly anthropogenic activities, such drainage, extraction, eutrophication. deterioration quality will result significant loss regional pool Carpathians.
