The effect of seasonality on the foraging behaviour and breeding success of a tropical marine top predator Open
In polar and temperate regions seasonality in environmental conditions is an important driver of animal phenology. In tropical systems, where the environment is relatively homogeneous year-round, the link between phenology and seasonality …
Competition and Facilitation Influence Central Place Foraging Ecology in a Colonial Marine Predator Open
Coloniality is strongly shaped by aspects of social foraging behaviour. For example, colonies may be important sources of information, while food competition may increase foraging efforts and limit colony size. Understanding foraging ecolo…

Northern Gannet foraging trip length increases with colony size and decreases with latitude Open
Density-dependent competition for food influences the foraging behaviour and demography of colonial animals, but how this influence varies across a species’ latitudinal range is poorly understood. Here we used satellite tracking from 21 No…

Animal behaviour on the move: the use of auxiliary information and semi-supervision to improve behavioural inferences from Hidden Markov Models applied to GPS tracking datasets Open
Background State-space models, such as Hidden Markov Models (HMMs), are increasingly used to classify animal tracks into behavioural states. Typically, step length and turning angles of successive locations are used to infer where and when…
Feces DNA analyses track the rehabilitation of a free-ranging beluga whale Open
Following the sudden appearance, and subsequent efforts to support the survival of a beluga whale ( Delphinapterus leucas ) speculated to have been previously trained off the coast of Norway, we investigate the animal’s ability to readapt …
Back Into the Wild: Feces DNA Analyses Track the Return of a Beluga Whale Back to Its Natural Environment Open
Following the sudden appearance, and subsequent rehabilitation of an assumed previously captive beluga whale off the coast of Norway, we investigate the animal’s ability to readapt to life in the wild. Using DNA analysis, a survey was set …
High mortality rates in a juvenile free‐ranging marine predator and links to dive and forage ability Open
High juvenile mortality rates are typical of many long‐lived marine vertebrate predators. Insufficient development in dive and forage ability is considered a key driver of this. However, direct links to survival outcome are sparse, particu…
Validation of Dive Foraging Indices Using Archived and Transmitted Acceleration Data: The Case of the Weddell Seal Open
Dive data collected from archival and satellite tags can provide valuable information on foraging activity via the characterization of movement patterns (e.g., wiggles, hunting time). However, a lack of validation limits interpretation of …
Body condition influences ontogeny of foraging behavior in juvenile southern elephant seals Open
Ontogeny of diving and foraging behavior in marine top predators is poorly understood despite its importance in population recruitment. This lack of knowledge is partly due to the difficulties of monitoring juveniles in the wild, which is …
Early‐life foraging: Behavioral responses of newly fledged albatrosses to environmental conditions Open
In order to survive and later recruit into a population, juvenile animals need to acquire resources through the use of innate and/or learnt behaviors in an environment new to them. For far‐ranging marine species, such as the wandering alba…
Processing of acceleration and dive data on‐board satellite relay tags to investigate diving and foraging behaviour in free‐ranging marine predators Open
Biologging technologies are changing the way in which the marine environment is observed and monitored. However, because device retrieval is typically required to access the high‐resolution data they collect, their use is generally restric…
Seabird diving behaviour reveals the functional significance of shelf-sea fronts as foraging hotspots Open
Oceanic fronts are key habitats for a diverse range of marine predators, yet how they influence fine-scale foraging behaviour is poorly understood. Here, we investigated the dive behaviour of northern gannets Morus bassanus in relation to …
