The round goby Neogobius melanostomus is one of the most wide‐ranging invasive fish on
earth, with substantial introduced populations within the Laurentian Great Lakes watershed …

The notion that men are more variable than women has become embedded into scientific
thinking. For mental traits like personality, greater male variability has been partly attributed …

Intersex is defined as the simultaneous presence of male and female gonadal tissue in a
gonochoristic (fixed-sex) species. The intersex condition has been documented in both wild …

Few studies have systematically investigated differences in performance, morphology and
parasitic load of invaders at different stages of an invasion. This study analyzed phenotype …

In many animal species, males may exhibit one of several discrete, alternative ways of
obtaining fertilisations, known as alternative reproductive tactics (ARTs). Males exhibiting …

Abstract Invasions of Ponto-Caspian gobiid fishes are suspected to cause regime shifts in
freshwater ecosystems. This study compared the trophic niche differentiations of Neogobius …

The invasive round goby, Neogobius melanostomus, consumes eggs and fry of other fishes,
competes for resources with native fish species, and hence poses a threat to Great Lakes …

Males that exhibit alternative reproductive tactics (ARTs) often differ in the risk of sperm
competition and the energetic trade-offs they experience. The resulting patterns of selection …

Fish can undergo changes in their life‐history traits that correspond with local demographic
conditions. Under range expansion, a population of non‐native fish might then be expected …

Although the round goby, Neogobius melanostomus, is widespread in the Great Lakes and
has an extended breeding season with a high reproductive rate; its spawning behaviour …
