Divergent life histories of invasive round gobies (Neogobius melanostomus ) in Lake Michigan and its tributaries

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...

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

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...

Little 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...

Evidence 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 ...
