The impact of invasive alien species on native communities can act at different levels both by affecting the ecosystem’s structure (i.e., mainly in case vegetation) and through direct interactions competition for food or space). Behavioral studies under controlled conditions provide relevant information potential invaders local species. In laboratory, resources between oriental shrimp Palaemon ...

Каменная креветка Palaemon elegans Rathke, 1836 – широко распространенный инвазивный вид, бентофаг-полифаг, значимый в питании рыб, ряде стран промысловый объект. После вселения Балтийское море успешно акклиматизировалась, распространилась, вытеснив аборигенные виды креветок палемонов. Наблюдается недостаток знаний о биологии креветки из морских поселений у берегов Калининградской области. Полу...

Anthropogenic carbon dioxide-induced ‘ocean acidification’ is predicted to have major implications for marine organisms. As the oceans becomes increasingly hypercapnic (elevated CO2) and seawater pH decreases, the ability of organisms to maintain extracellular pH homeostasis (acid– base balance) may be compromised. Acid–base regulation occurs by ionic transport, where hydrogen and bicarbonate i...

In this study, we investigated (using bioassays and ELISA) the variation of cHH (crustacean hyperglycemic hormone) level in the eyestalks and hemolymph of Palaemon elegans (Rathke) (Decapoda, Caridea) following injection of serotonin (5-HT) and dopamine (DA) and correlated cHH profile with the variation in amount and time course of glycemia. 5-HT induced in P. elegans a rapid and massive releas...
