Population structure, reproductive parameters and other life history traits are among the main preconditions for alien amphipods’ successful invasion. In freshwaters of Northern Europe, i.e. Latvia, overall Ponto-Caspian amphipods is little known. Furthermore, population structure reproductivity native Gammarus pulex have not been studied in Latvian freshwaters. The aim study was to describe va...
Microplastic pollution of freshwaters is known to be a great concern in China and these pollutants can discharged into the coastal environment through fluvial processes, posing threats global marine ecosystem. This paper reviewed literature measuring microplastic Chinese freshwater found that microfibres dominate other plastic morphologies more than 65% samples collected surface water, sediment...
Lake water samples were observed to transform [14-C]ethylene into water-soluble compounds that were undetectable by conventional acetylene reduction assay procedures. Methane oxidizing bacteria, which are known to be common in freshwaters, appeared to be responsible for this activity. As much as 28 percent of added ethylene has been observed to be transformed and this figure is probably an unde...
The first species of falklandellid amphipod outside the Falkland Islands: Osornodella gabrielae n. gen., n. sp. is described from freshwaters of subterranean origin in the Coastal Range of Osorno province, Chile. The new taxon is characterized principally by the absence of secondary sexual characters in pereopods 3-4, uropod 3 aequiramous and telson slightly cleft. The new species is described ...
