“…Sex also played an important role: male round goby were more explorative and had a greater propensity to move than females, and also moved further in the field between years than did females. Greater male movement (exploration, home range size and between-year dispersal) is expected in this polygamous species, where males are also larger and grow faster than females, and may therefore precede females in invasion fronts (Marentette et al 2011). Site effects were consistent within each sex.…”

“…Round goby (N = 198) were collected between 16 May and 25 July 2008 from three locations described above (LS, P27 and SI) and housed in sex-and site-specific 60 L holding tanks (Marentette et al 2011). Fish were held under a shifted 16L:8D light cycle, with the dark phase between 1200 and 2000 h, to facilitate behavioral observations performed in the nocturnal phase under red light (when round goby are most active; Dubs and Corkum 1996;Diana et al 2006).…”

Changes in animal movement (frequency or speed of locomotion) following exposure to a toxicant are frequently considered a biomarker of contaminant exposure and are some of the most widely reported behavioral results in toxicological literature. However, the ecological consequences of such behavioral changes, such as effects on toxicant transfer in foodwebs, are far less well understood, complicated in part by the short-term nature of laboratory experiments and the lack of complementary field studies where the nature of toxicant exposure is more complex. Here we examine whether naturally exposed individuals of the round goby, a benthic, site-loyal fish, move in a manner similar to conspecifics from less contaminated habitats. In the laboratory, round goby from a relatively cleaner site showed greater activity and exploration than goby from two highly contaminated sites. Male fish were more active than females but the site effects were similar in both sexes. In contrast to laboratory findings, a field mark-recapture study of 881 round goby showed that fish from the cleaner site did not move greater distances or exhibit shorter residence times within the site than round goby from highly contaminated sites. Our results indicate that while behavioral changes in the laboratory may be one of several useful diagnostics of toxicant exposure of wild-exposed animals, they do not necessarily translate readily into measurable differences in a natural context. Thus, the potential fitness consequences of toxicant exposure based on behavioral changes need to be assessed carefully.

“…This is true for many bird species, in which females search for males that occupy a breeding territory (Greenwood, 1980;Clarke et al, 1997). Much less is known regarding fishes and the number of studies that have examined sex-biased movement (here defined as the stream distance covered per time unit) in fish are still very limited (Hutchings & Gerber, 2002;Croft et al, 2003;Marentette et al, 2011).…”

“…Studies that cover both short-and longterm movements of a fish species and differentiate between the sexes are rare (but see e.g. Natsumeda, 1999;Marentette et al, 2011), but may help to detect periodical changes in sex-biased movement.…”

“…The present article aims to contribute to the paucity of studies examining sex-biased movement in fishes under consideration of the reproductive behaviour (Hutchings & Gerber, 2002;Croft et al, 2003;Marentette et al, 2011) and also takes plausible periodical variations into account. A fish species that is particularly suitable to study sex-biased movement is the bullhead (Cottus perifretum Freyhof, Kottelat & Nolte 2005), a small fish that belongs to the genus Cottus (freshwater sculpins) and is found in streams and rivers in Middle Europe.…”

Anthropogenic structures can form novel ecosystem niches. Invasive species are often particularly successful in occupying these habitats and utilize them as beachheads for further spread. The invasive round goby (Neogobius melanostomus, Pallas 1814), an inherently bottom‐dwelling fish, uses vertical harbor walls as habitat, enabling them to reach boats (i.e., potential translocation vectors). To evaluate the relevance of vertical habitat use for population dynamics and translocation, we exemplary investigated a population of round gobies in a harbor ecosystem. Specifically, we investigated differences in trophic niche characteristics, individual trophic specialization, phenotypic traits, and breeding frequency in wall versus bottom‐dwelling round gobies. Habitat‐characteristic dietary signatures indicated habitat partitioning during the breeding season. Trophic niches overlapped but were clearly distinguishable between the habitats: Walls were inhabited by 1.4 times more trophic generalists than specialists, while the bottom was inhabited by 2.1 times more trophic specialists. Breeding frequency was 24 times higher on the walls than on the bottom. After the reproductive season, we found a higher similarity in trophic ecology of gobies inhabiting the two habitats, and differences in abundance, size, and condition. These results are in line with winter migrations to deeper habitats, which are common in round gobies in lentic and marine ecosystems. Our results suggest a high potential for microgeographic adaptation to either horizontal or vertical habitat use in invasive round gobies. We demonstrated that male gobies using the walls during the breeding season are larger and heavier, suggesting that wall climbing may select for more competitive individuals. Additionally, the overall abundance of round gobies likely increases with the additional use of vertical habitat space, which may lead to higher propagule pressure. The ability to exploit anthropogenic habitats, and a higher translocation probability of competitive individuals, can contribute to the invasion success of round gobies in anthropogenically influenced aquatic systems.
