The extraordinary fossil sites of Vlădiceni (Iaşi, Romania) recently discovered, with lithostratigraphy Middle Miocene age, have uncovered a rich fauna especially fishes, molluscs, amphipods and insects. This includes also the first specimen family Cantharidae from both this geological formation Romania: Malthodes ( ) vladiceniensis sp. nov. , which is illustrated described co...

Parasites can structure biological communities directly through population regulation and indirectly by processes such as apparent competition. However, the role of parasites in the process of biological invasion is less well understood and mechanisms of parasite mediation of predation among hosts are unclear. Mutual predation between native and invading species is an important factor in determ...

As a result of our studies the macro- and nectozoobenthos rivers semidesert zone (the Volgograd reservoir basin), 16 Malacostraca species were recorded, most which are representatives Ponto-Caspian complex. Compared to reservoir, there is an increase in quantitative indicators mysids isopods decrease number species, abundance biomass amphipods cumaceans semi-desert rivers. The average crustacea...

The impact of parasitism on population dynamics and community structure of marine animals is an area of growing interest in marine ecology. The effect of a microphallid trematode, Maritrema novaezelandensis on the survival of its amphipod host, Paracalliope novizealandiae, was investigated by a laboratory study combined with data from field collections. In the laboratory, the effect of infectio...
