Signatures of contamination in invasive round gobies (Neogobius melanostomus): a double strike for ecosystem health?

Isotope evidence for preferential dispersal of fast-spreading invasive gobies along man-made river bank structures.

Invasive round goby Neogobius melanostomus and bighead goby Ponticola kessleri have successfully colonized freshwater and coastal habitats worldwide. The objective was to use stable isotope analyses to study the foraging and movement of both species at small spatial scales in the Upper Danube River, considering 861 samples from two different years, seasons and sides of the river in an area wher...

Impacts 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...

Gorging on gobies: beneficial effects of alien prey on a threatened vertebrate

Invasive species often have rapid and far-reaching negative impacts on populations and ecological communities. These effects are most common when invasive species have few competitors or predators. Although higher level carnivores do consume invasive species, quantitative effects of new and abundant food sources on predators have rarely been documented and, as a consequence, potentially positiv...

In revision IMPACT OF ROUND GOBIES (Neogobius melanostomus) ON LITHOPHILIC INVERTEBRATES ACROSS AN INVASION FRONT

What's in a name? Taxonomy and nomenclature of invasive gobies in the Great Lakes and beyond

Index words: Gobiidae Invasive species Neogobius Proterorhinus Round Goby Tubenose Goby The species identities, scientific names, and relationships of Eurasian gobies that invaded the Laurentian Great Lakes – and other species that are predicted to invade in the future – are evaluated here using recently resolved DNA characters. The Round Goby and the Freshwater Tubenose Goby entered the Great ...
