Assessment of fish size on shelter choice and intraspecific interactions by round gobies Neogobius melanostomus

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

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

The invasive round goby has a recognised role in transferring contaminants through foodwebs, but little work has been done on contaminant impacts on round gobies themselves. Here we present the first case study of contaminant biomarkers and subpopulation structure variation in round gobies, in relation to habitat contamination, within a Canadian Area of Concern, Hamilton Harbour. Copper and cad...

Olfactory sensory input increases gill ventilation in male round gobies (Neogobius melanostomus) during exposure to steroids.

In teleostean fish, ventilation increases have been observed in response to low dissolved oxygen levels, visual stimuli, and gustatory cues. However, olfactory sensory input may also stimulate gill ventilation rate. We investigated whether olfactory sensory input mediates gill ventilation responses, as suggested by the observation that steroidal compounds detected by the olfactory system elicit...

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...

Getting 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....
