Riverine communities have been subject to numerous biological invasion events, with crustaceans among the most successful group of invasive animals worldwide. Understanding what makes a river system prone is considerable interest environmental regulators, resource managers, scientists and wider society globally. The Ponto-Caspian amphipod, Dikerogammarus haemobaphes (Crustacea: Gammaridae), hyp...

1. Reduced metabolic rate among cave organisms compared with surface species has long been suggested as an adaptation to food shortage in cave environments. However, comparisons of metabolic rates between species have not often included closely related surface and cave species. By measuring metabolic rate across three seasons and over a range of body sizes, we examined the hypothesis that the r...

Inland epigean freshwater amphipods of Romania are diverse and abundant for this region has a favourable geographical position between the Balkans and the Black Sea. Excluding Ponto-Caspian species originating in brackish waters and freshwater subterranean taxa, there are 11 formally recognized epigean freshwater species recorded from this country. They belong to 3 genera, each representing a d...

This is the first comprehensive examination of Turyanchay River in Azerbaijan, focusing on water quality (WQ), contamination, and biodiversity at four different locations: Gabala, Agdash, Udjar Zardab. The study analysed nutrient (nitrate, ammonium, phosphate) metal/metalloid (Pb, Cu, Ni, Zn, Mn, Cr, Cd, Fe Al) contamination levels, as well diversity macrozoobenthos river, birds vegetation. che...
