Rays (superorder Batoidea) are the most diverse group of elasmobranchs, and many are
threatened with extinction. However, there remain areas where research on the ecology of …

Although predators influence behavior of prey, analyses of electronic tracking data in marine
environments rarely consider how predators affect the behavior of tracked animals. We …

Most stocks of Atlantic cod (Gadus morhua) in the Northwest Atlantic collapsed in the early
1990s, with little sign of recovery since then. In the southern Gulf of St. Lawrence (sGSL), the …

The effects of predator intimidation on habitat use and behavior of prey species are rarely
quantified for large marine vertebrates over ecologically relevant scales. Using state space …

Estimating trends in abundance from fishery catch rates is one of the oldest endeavors in
fisheries science. However, many jurisdictions do not analyze fishery catch rates due to …

Predation and mortality are often difficult to estimate in the ocean, which hampers the
management and conservation of marine fishes. We used data from pop-up satellite archival …

Stock assessment models often assume natural mortality rates (M) are constant and attribute
the variability in a stock's overall mortality rate to variability in fishing mortality and …

Aim The interdependencies between trophic interactions, environmental factors and
anthropogenic forcing determine how species distributions change over time. Large …

Increasing predation danger can select for safety‐enhancing modifications to prey
morphology. Here, we document the multi‐decade wing lengthening of a Pacific flyway …

The Atlantic cod (Gadus morhua) stocks in the Newfoundland-Labrador Shelves (NL) and
Barents Sea (BS) ecosystems have shown divergent trajectories over the last 40 years. Both …
