In a recent study, we showed how local-scale climate change impacts (increased temperature, reduced rainfall, shifts in peak rainfall) affected the hydrology of channelised lowland European river (reduced flow, reduction flood events, increased siltation, macrophyte growth), allowing native fish species to recolonise bankside zone and reduce density invasive round goby Neogobius melanostomus by...

Ecosystems are simultaneously regulated by bottom-up (resources) and top-down forces (predators). However, because predator-prey interactions operate on spatial scales beyond the reach of manipulative experimentation, actual roles predators remain poorly understood. In ecosystems where naturally absent, biological invasions provide a unique experiment to shed light large-scale long-term effects...

Aquatic surveys for fish in large water bodies (e.g., Laurentian Great Lakes of North America) often require a flexible approach using multiple methods, surveying different depths, and sampling across seasons, especially when the target species is elusive its natural habitat. The round goby (Neogobius melanostomus) an invasive, bottom-dwelling inhabiting rocky areas all five Lakes. While trawl ...
