Little association of biological trait values with environmental variables in invasive alien round goby (Neogobius melanostomus)
The relative importance of species-specific biological trait characteristics and environmental factors in invasions of nonindigenous species remains controversial because both have mostly been studied independently. Thus, the main objective of this study was to examine the correlation of biological traits with environmental variation in the globally invasive round goby Neogobius melanostomus fr...
متن کاملFirst record of round goby, Neogobius melanostomus (Pallas, 1814) in the Sava River, Croatia
In June 2011, 34 specimens of round goby (Neogobius melanostomus) were caught at three different locations in the Sava River in Croatia, which is a first record of this invasive species in Danube tributaries in Croatia. Size, structure and condition of populations indicate that the species is well adjusted to its new habitat and that further range expansions are highly likely.
متن کاملSignatures of contamination in invasive round gobies (Neogobius melanostomus): a double strike for ecosystem health?
The invasive round goby has a recognised role in transferring contaminants through foodwebs, but little work has been done on contaminant impacts on round gobies themselves. Here we present the first case study of contaminant biomarkers and subpopulation structure variation in round gobies, in relation to habitat contamination, within a Canadian Area of Concern, Hamilton Harbour. Copper and cad...
متن کاملEvidence for ontogenetically and morphologically distinct alternative reproductive tactics in the invasive Round Goby Neogobius melanostomus
Alternative reproductive tactics are characterized by the occurrence of discrete alternative morphs that differ in behavioural, morphological and physiological traits within the same sex. Although much effort has been made to describe the behaviour, morphology and physiology of such alternative morphs, less effort has been invested investigating how much overlap there is in the characteristics ...
متن کاملGetting What Is Served? Feeding Ecology Influencing Parasite-Host Interactions in Invasive Round Goby Neogobius melanostomus
Freshwater ecosystems are increasingly impacted by alien invasive species which have the potential to alter various ecological interactions like predator-prey and host-parasite relationships. Here, we simultaneously examined predator-prey interactions and parasitization patterns of the highly invasive round goby (Neogobius melanostomus) in the rivers Rhine and Main in Germany. A total of 350 N....
