Sexual size dimorphism (SSD) is often affected by environmental conditions, but the effect of temperature on SSD in ectotherms still requires rigorous investigation. We compared the plastic responses of size-at-maturity to temperature between males and females within 85 diverse arthropod species, in which individuals of both sexes were reared through ontogeny under identical conditions with exc...

The play an important role to study is the faunal biodiversity of an aquatic ecosystem. The zooplankton recorded with the present study belonged to some taxa including, Foraminifera, Calanoida, Cheatognatha, Appendicularia, Polychaeta, Hydrozoa, Echinodermata, fish eggs and larvae. Rotifers were found in all stations. Fish eggs and larvae occurred throughout the year, but had peak abundance in ...

This study presents the diversity and structure of pelagic zooplankton in north-eastern Poland. The research was conducted 47 lakes with different trophic conditions middle summer. Samples were collected close to deepest part avoid diverse benthic littoral zones. We found 119 species which 32 Cladocera, 16 Cyclopoida, 4 Calanoida, 67 Rotifera. determined occurred most frequently region, as well...
