Recent invasions by non-native gobiid fish species that are ongoing in the Western European rivers Rhine and Meuse, will lead to interactions with native benthic fish species. Since both non-native gobiids and native benthic species are bottom dwelling species with a preference for shelter during at least part of their life cycle, it is likely that competition for shelter will occur between the...

Abstract Biological invasion is a strong threat to native biodiversity, with limnic systems being especially vulnerable due historical separation and resulting prey naivety. The naivety hypothesis states that species may not be able recognize novel predators lack of common evolutionary background and, therefore, become easy targets. In laboratory experiment, we added cues European bullhead ( Co...

The species composition of the ichthyofauna Samara River under influence man-made factors in Novomoskovsk district Dnipropetrovsk region is presented. environmental problem characterized, and on revealed. was analyzed based literature data, field ichthyological studies were also conducted to determine River. results technogenic modern realities have been obtained are summarized relation ichthyo...

Abstract In this study, we provide the first genetically verified distribution record beyond its native range of Ligula pavlovskii, a high-impact endoparasite Ponto-Caspian gobies. According to parasitological surveys, ligulosis was detected for time in monkey goby individuals collected from Lake Balaton 2004, 34 years after lake. During survey 2018, tapeworms 44.4% sampled This prevalence is a...

Species introductions and movements world-wide provide valuable, large-scale ‘natural’ experiments to test fundamental hypotheses underlying ecological and evolutionary theory and may provide insights into the broad morphological, genetic, ecological or life history characteristics associated with their success and persistence (Sax et al., 2007; Blackburn, 2008; Great Lakes Genetics Laboratory,...

Middendorff's work on the Säugethiere, Vögel und Amphibien, published as part 2 of volume 2 of his Reise in den äussersten Norden und Osten Sibiriens, was variably dated from 1851, 1852 or 1853. I document that the work was published shortly before 15 December 1852 and I recommend using this date for the purposes of zoological nomenclature.Due to this, Emberiza polaris Middendorff, 1852 has pre...
