Despite the fact that chlorinated paraffins have been produced in relatively large amounts, and high concentrations have been found in sewage sludge applied to soils, there is little information on their concentrations in soils and the effect on soil organisms. The aim of this study was to investigate the toxicity of chlorinated paraffins in soils. The effects of short-chain chlorinated paraffi...

in order to investigation of collembola fauna, several soil and leaf litter sampling were carried out during 2011 in kermanshah regions and species were extracted by berlise funnel. in sum, eight species from eight genera from seven families were collected and identified. the species characterized by one star (*) are new for kermanshah fauna. the species characterized by two star (**) are repor...

Organisms face trade-offs in their reproductive investment due to energetic constraints. Yet, little is known about how such investments may change at different temperatures, and particularly so soil invertebrate organisms. Here, we studied two Collembola species (Folsomia candida Proisotoma minuta) using a long term (several generations) temperature incubation experiment (separately 15 20 °C) ...
