Foraging Ecology and Behavior
Phocid seals exhibit a range of body sizes and life-history traits. They forage at a wide range of spatial scales from long-distance oceanic movements (e.g., northern elephant seals) to short local trips of re...

Genetic association with boldness and maternal performance in a free-ranging population of grey seals (Halichoerus grypus)
Individual variation in quantitative traits clearly influence many ecological and evolutionary processes. Moderate to high heritability estimates of personality and life-history traits suggest some level of ge...

Genetic diversity from pre-bottleneck to recovery in two sympatric pinniped species in the Northwest Atlantic
Conservation successes of the past several decades provide natural settings to study post-bottleneck evolutionary processes in species undergoing recovery. Here, we study the impact of demographic change on ge...

Repeatability and reproductive consequences of boldness in female gray seals
Wild animals show consistent individual variation in behavior across time and/or contexts, now referred to as animal personality. While this variability may have important ecological and evolutionary implicati...

Open AccessA novel approach to quantifying the spatiotemporal behavior of instrumented grey seals used to sample the environment
Paired with satellite location telemetry, animal-borne instruments can collect spatiotemporal data describing the animal’s movement and environment at a scale relevant to its behavior.

Mating tactics and mating system of an aquatic-mating pinniped: the harbor seal, Phoca vitulina
Our best understanding of marine mammal mating systems comes from land-mating pinnipeds. Logistical problems of observing behavior at sea have limited our ability to make inferences about species with aquatic-...

Does male harassment of females contribute to reproductive synchrony in the grey seal by affecting maternal performance?
We investigated the possibility that male harassment of lactating females differed in relation to time of birth in the grey seal, Halichoerus grypus, on Sable Island, Nova Scotia. This was done by comparing th...
