The parasite Ichthyophonus is enzootic in many marine fish populations of the northern Atlantic and Pacific Oceans. Forage fishes are a likely source of infection for higher trophic level predators; however, the processes that maintain Ichthyophonus in forage fish populations (primarily clupeids) are not well understood. Lack of an identified intermediate host has led to the convenient hypothes...

This study aims to describe animal bacterial associations with culture independent methods. Bacterial communities in the hepatopancreas of the following 7 species of isopods (Pericaridea, Crustacea, Arthropoda) from 3 habitat types were investigated: 2 subtidal species Idotea baltica (IB) and I. wosnesenskii (IG); 2 intertidal species Ligia occidentalis (LO) and L. pallasii (LP), and 3 terrestr...

Exposed regions of the arthropod exoskeleton have specialized structure and mineral composition. Their study can provide insights into evolutionary optimization cuticle as a material. We determined structural compositional features claws in crustacean Ligia pallasii using X-ray micro-computed tomography, scanning electron microscopy (SEM), analytical transmission (STEM). In addition, we used na...

Background and objectives: The goal of this study was to compare the cytotoxic and antioxidant activities of the corms extracts of two Crocus species (C. sativus L. and C. pallasii subsp. haussknechtii). Methods: n-Hexan, chloroform and methanol extracts of the corms were prepared. Cytotoxic activities of the extract...
