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 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 کاملAcoustic communication modalities of the round goby ( Neogobius melanostomus)
Acoustic communication is essential to survival for many fish species, however it is often understudied. This thesis investigates two areas of acoustic communication in the round goby (Neogobius melanostomus). These fish have no accessory hearing structures, and theory would predict they would be unable to localize sound sources, however it has been shown that round gobies can localize conspeci...
متن کاملImpacts of the Eurasian round goby (Neogobius melanostomus) on benthic communities in the upper St. Lawrence River
An invasive benthivorous fish, the Eurasian round goby (Neogobius melanostomus) is abundant throughout the lower Great Lakes – St. Lawrence River system. We examined the round goby’s potential to alter benthic communities on cobble substrates in the upper St. Lawrence River. During the summers of 2008 and 2009, macroinvertebrates and benthic algae were sampled across sites with varying goby den...
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.
