Acoustic 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 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....
متن کاملLittle 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 کاملInvasion strategies in round goby (Neogobius melanostomus): Is bigger really better?
Few studies have systematically investigated mid- or long-term temporal changes of biological characteristics in invasive alien species considering the different phases of an invasion. We studied the invasion performance of one of the most invasive species worldwide, the round goby Neogobius melanostomus, from total absence over first occurrence until establishment from 2010 to 2015 in the uppe...
