As benthic predators, Black Carp poses ecological risks to unionids within the Great Lakes and could bring other changes to local benthic communities. One means of assessing invasion risk and potential impact is to determine how critical life history characteristics depend on environmental conditions in new regions. Age at sexual maturity is negatively correlated to the maximum per capita population growth rate and thus can be used to estimate potential population growth for invasive species. Previous studies have found a significant negative relationship between age at maturity and temperature for all three other Asian Carp species, but not for Black Carp. With a more comprehensive dataset, we demonstrate that the same relationship exists for Black Carp. Winter duration is the best predictor of Black Carp age at maturity, followed by average winter air temperature. This significant relationship between age at maturity and temperature was not altered in artificial growing environments.

We speculate that high migration success in standing waters could be due to relative current speeds providing good quality directional cues to migrants. Migration success past the two dams in this study, was relatively high, although the number of unsuccessful passage attempts before a successful passage was also very high. The vast majority of smolts passed the dams when the turbines were operational. At one dam, smolts did not use an available fish pass but migrated through the generating turbines.

The third was in 2010 back in the stunning fishing town of Luarca, where our numbers grew substantially to more than 115, we moved into a fancy new conference hall, and we feasted on fresh seafood. The fourth was in 2015 and held in Girona (101 scientists), in the NE of Spain, where we all felt ethereal while giving our talks in a stunning cathedral-like hall and where we experienced the strong Catalonian culture and cuisine.

To unravel the diversity and ecological relationships of piscivorous charrs, we analysed their morphology and microsatellite DNA polymorphism, distribution within the lake, trophic preferences and parasite load, as well as trace element accumulation, stable isotope and free fatty acid ratios. We revealed that, apart from a few strictly benthivorous morphs, the lake is inhabited by four closely related but morphologically and genetically distinct morphs that exhibit a range of piscivorous specialisation: from opportunistic secondary predation to ultra-specialised primary piscivory. They effectively exploit the spatiotemporal structure of the ecosystem and experience diversifying selection due to niche discordance. Each piscivorous morph develops specific phenotypic, ecological and life history traits that allow it to terminate weakly overlapping branches of the trophic chain and share the energy flows of the lake ecosystem.

Largemouth bass ontogenetically shifted their diet from aquatic invertebrates to fishes and a more diverse assemblage of aquatic invertebrates. Bowfin and adult largemouth bass were top predators which consumed mostly crayfish and fish and overlapped in their diets. Despite overlapping diets, predators partitioned resources by consuming different lengths and abundances of prey, and largemouth bass had greater trophic plasticity. Within a predator group, few differences in diets existed spatially, underscoring the relative homogeneity in resource use potentially from similarities in the river's physical structure.

Anadromous salmonids are an interesting system for examining dispersal, in part because of their well-known philopatric behaviour, but also because of the conservation challenges related to the dispersal of hatchery-origin fish. Building on earlier work, we provide an updated systematic review of dispersal and gene flow in anadromous salmonids. In particular, we compared studies on the dispersal of anadromous salmonids from wild and hatchery origins, including studies providing estimates of dispersal rates, observations of dispersal and results from modelling studies. We reviewed 228 studies and found these were unevenly distributed among species, with Atlantic salmon, Chinook salmon and sea trout being well-represented. Our results showcase considerable variability in estimated dispersal rates within and across studies, which is likely related to the different methodologies, dispersal propensities across species and populations, and spatial extents considered. Overall, our results confirmed a higher tendency of hatchery fish to disperse relative to wild fish, but we also found some variation across species that warrants further study. Moreover, we found that dispersal propensity tended to decline exponentially with distance and that the drivers of dispersal varied considerably among studies. Additionally, we highlight various facets of dispersal captured across this suite of studies, including variation in terminology, methods and metrics for characterising dispersal, and the spatio-temporal scales considered.

We examined the influence of hydrological variability on the structure and diversity of freshwater fish assemblages across rivers of the wet-dry tropics of northern Australia. We found distinct fish assemblages that varied predictably across three hydrological river types: Intermittent, Perennial Stable and Perennial Flashy flow regimes. This distinction emerged despite a common species pool across the region. Species richness was greatest in rivers with Perennial Stable flow regimes, whereas beta-diversity was greatest in Intermittent rivers. However, life history strategies of constituent species were generally poor predictors of species abundances within each hydrological river type.
