Investigation of False Scorpions (Chelicerata: Pseodoscorpions) and Isopods (Cerastacea: Isopoda) Fauna and Their Population Dynamics in a Forest Soil Hyrcanian

In this study, fauna and population dynamics of Pseudoscorpions and Isopods in Semeskandeh forest (as Hyrcanian forest) soil was studied during one year in different seasons. For these reasons, samples from leaf litter (OL,F,H), the 0-3 cm and 3-6 cm of soil layer (Ah) were assessed in 2 month intervals during 1 year sampling (2012-2013). For Pseuodoscorpions fauna totally, 2 genus and 4 species belonging 2 families and 3 class were collected and identified. Also for Isopoda fauna totally, 2 genus and 2 species belonging 2 were collected and identified. Abundance of these Arthropods was highest in leaf litter in autumn and the lowest in deepest layer of soil in spring. Density of these Arthropods was highest in leaf litter in autumn and the lowest in deepest layer of soil in April and December.
