Environment‐recruitment relationships often break down over time. This can occur because of spurious results from testing numerous environmental variables in the original analyses or from relative changes in the importance of specific environmental drivers over time. An environment‐recruitment model was developed for the Newfoundland and Labrador capelin stock, but the relationship first weakened with the addition of new data...

The Newfoundland capelin stock in Northwest Atlantic Fisheries Organization Divisions 2J3KL collapsed in 1991 with only a modest recovery over 30+ years. Resource limitation is hypothesized to be a driver of this slow stock recovery. Using detailed seasonal diet data (1999–2022), capelin diet was dominated by calanoid copepods in both spring and autumn, with hyperiid amphipods, euphausiids, and appendicularians increasing in i...

Bighead carp H . nobilis and silver carp Hypothalmichthys molitrix (collectively bigheaded carps, BHC) are invasive planktivorous fishes that threaten to enter the Laurentian Great Lakes and disrupt food webs. To assess the likelihood of BHC establishment and their likely effects on the food web of Saginaw Bay, Lake Huron, we developed a multi-species individual-based bioenergetics model that tracks individual bighead and silv...

Rapid increases in global trade and human movement have created novel mixtures of organisms bringing with them the potential to rapidly accelerate the evolution of new forms. The common brushtail possum ( T richosurus vulpecula ), introduced into N ew Z ealand from A ustralia in the 19th century, is one such species having been sourced from multiple populations in its native range. Here, we combine microsatellite DNA ‐ and GIS...
