The recent distribution and abundance of non-native Neogobius fishes in the Slovak section of the River Danube
TLDR
The distributions of invasive Neogobius species were investi- gated in the Slovak section of the River Danube from Bratislava downstream to the village of Chl'aba during October 2004, and monkey goby had a most limited distribution. Expand
Sexual selection for male dominance reduces opportunities for female mate choice in the European bitterling (Rhodeus sericeus)
TLDR
It was showed that even though larger body size was favoured in both intersexual and intrasexual selection, male–male interference competition reduced opportunities for female choice, and females, despite being choosy, had limited control over the paternity of their offspring. Expand
Condition status and parasite infection of Neogobius kessleri and N. melanostomus (Gobiidae) in their native and non-native area of distribution of the Danube River
TLDR
Differences in success of the introduction and establishment in new areas between the two fish species may be associated with a relatively low parasite infection rate and a higher gonadosomatic index in non-native populations of N. kessleri. Expand
Morphology and coexistence of congeneric ectoparasite species: reinforcement of reproductive isolation?
TLDR
The results support the prediction that the function of niche segregation is to achieve reproductive isolation of related species in order to prevent hybridization and suggest small effects of interspecific competition for the evolution of morphological diversity of attachment organs. Expand
Tubenose goby Proterorhinus marmoratus (Pallas, 1814) has joined three other Ponto-Caspian gobies in the Vistula River (Poland).
TLDR
The Ponto-Caspian fish species, tubenose goby Protherorhinus marmoratus, was recorded for the first time in Poland during April 2008, and appears to be the next stage in the species’ westward invasion through the so-called ‘central invasion corridor’ for Ponto, Caspian species. Expand
Metazoan parasites of Neogobius fishes in the Slovak section of the River Danube
TLDR
Metazoan parasites were investigated in three non-native fishes collected from the former and current main channel of the River Danube and from the River Hron, Slovakia in November 2003, finding all parasite species found are common parasites in the Middle Danube basin. Expand
Invasive gobies in the Danube: invasion success facilitated by availability and selection of superior food resources
TLDR
Rich food resources utilised by the non-native bighead and round goby contribute to their invasive success in the upper Danube. Expand
Parasite fauna of native and non-native populations of Neogobius melanostomus (Pallas, 1814) (Gobiidae) in the longitudinal profile of the Danube River
TLDR
Parasite fauna of round goby Neogobius melanostomus in the Danube River was investigated in both the native range and the non-native range of its distribution during 2005 and 2006 to identify possible changes in parasite community associated with the introduction of a host into the new environment. Expand
The interaction between an introduced fish host and local parasite fauna: Neogobius kessleri in the middle Danube River
TLDR
The importance of gobies as suitable hosts for local non-native parasite species (Anguillicoloides crassus, Anodonta woodina, Hydrozetes lacustris) is discussed and the role of introduced N. kessleri was used as intermediate host for most of the recorded parasites. Expand
