Journal ArticleDOI
A review of Gobiid expansion along the Danube-Rhine corridor – geopolitical change as a driver for invasion
TL;DR: In this paper, the authors provide an upto-date literature review of first records of occurrence for all five Gobiid fish species along their expansion route, and examine available shipping data to identify possible proximal causes of introduction.
Journal ArticleDOI
The recent distribution and abundance of non-native Neogobius fishes in the Slovak section of the River Danube
Pavel Jurajda,Jaroslav Černý,Matej Polačik,Zdenka Valová,Michal Janáč,Radim Blažek,Markéta Ondračková +6 more
TL;DR: 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.
Journal ArticleDOI
Invasive gobies in the Danube: invasion success facilitated by availability and selection of superior food resources
Matej Polačik,Michal Janáč,Michal Janáč,Pavel Jurajda,Zdenek Adámek,Markéta Ondračková,Markéta Ondračková,Teodora Trichkova,Milen Vassilev +8 more
TL;DR: Rich food resources utilised by the non-native bighead and round goby contribute to their invasive success in the upper Danube.
Journal ArticleDOI
Downstream drift of round goby (Neogobius melanostomus) and tubenose goby (Proterorhinus semilunaris) in their non‐native area
TL;DR: This is the first study to demonstrate passive downstream dispersal (drift) of the round goby and tubenose goby in newly colonised areas (River Dyje, Danube basin) and Drift of early life stages appears to be an important phenomenon that has not received adequate attention in studies of round and tuberhinus goby ecology and dispersal.
Journal ArticleDOI
The distribution and abundance of the Neogobius fishes in their native range (Bulgaria) with notes on the non-native range in the Danube River
TL;DR: The results support the hypothesis of disjunct spreading of these species and suggest newly established populations of N. kessleri and N. melanostomus were significantly larger at sites of non-native distribution compared to native sites.
