The round goby ( Neogobius melanostomus ) was first observed in the Baltic Sea 1990 and has since displayed substantial secondary dispersal, establishing numerous dense populations where they may outcompete native fish negatively impact prey species. There have been multiple diet studies from both North American Great Lakes are similarly invasive. However, that quantify their effects on recipie...

Salinity is an influential abiotic environmental factor in aquatic species, specifically freshwater, where salinization causes ecosystem degradation. Secondary salinization, that increases salinity due to anthropogenic activities, can affect both osmoregulation and behaviour freshwater fishes. It generally believed invasive species handle climatic change degradation better than native which one...

Animal personalities are an important factor that affects the dispersal of animals. In the context of aquatic species, dispersal modeling needs to consider that most freshwater ecosystems are highly fragmented by barriers reducing longitudinal connectivity. Previous research has incorporated such barriers into dispersal models under the neutral assumption that all migrating animals attempt to a...

Invasion biology research has identified two juxtaposing behavioural traits, aggressiveness and sociality, that may both increase the success of species invasions. Highly aggressive invaders can out-compete native species for resources, while social gregarious invaders can tolerate high conspecific density. In order to tease apart the effects of aggressive versus social tendencies on the succes...

Chemical communication occurs when both originator (signaller) and one or more receiver(s) possess specializations for chemical exchange of information. Chemical information can be used by a wide variety of species to locate food and mates, avoid predators and engage in social interactions. In this review, we focus on chemical signalling between mates or cues from nest sites or hosts by selecte...
