Open AccessLinking movement and dive data to prey distribution models: new insights in foraging behaviour and potential pitfalls of movement analyses
Animal movement data are regularly used to infer foraging behaviour and relationships to environmental characteristics, often to help identify critical habitat. To characterize foraging, movement models make a...

Open AccessMovements of southern elephant seals (Mirounga leonina) from Davis Base, Antarctica: combining population genetics and tracking data
Marine animals such as the southern elephant seal (Mirounga leonina) rely on a productive marine environment and are vulnerable to oceanic changes that can affect their reproduction and survival rates. Davis Base...

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...

Open AccessA continuous-time state-space model for rapid quality control of argos locations from animal-borne tags
State-space models are important tools for quality control and analysis of error-prone animal movement data. The near real-time (within 24 h) capability of the Argos satellite system can aid dynamic ocean mana...

Open AccessState-space models’ dirty little secrets: even simple linear Gaussian models can have estimation problems
State-space models (SSMs) are increasingly used in ecology to model time-series such as animal movement paths and population dynamics. This type of hierarchical model is often structured to account for two lev...

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.

Open AccessDaily activity budgets reveal a quasi-flightless stage during non-breeding in Hawaiian albatrosses
Animals adjust activity budgets as competing demands for limited time and energy shift across life history phases. For far-ranging migrants and especially pelagic seabirds, activity during breeding and migrati...

Open AccessBehavioral attributes of turbine entrainment risk for adult resident fish revealed by acoustic telemetry and state-space modeling
Fish entrainment through turbine intakes is one of the major issues for operators of hydropower facilities because it causes injury and/or mortality and adversely affects population abundance. Entrainment redu...

A multi-phase correlation search framework for mining non-taxonomic relations from unstructured text
Over the last decade, ontology engineering has been pursued by “learning” the ontology from domain-specific electronic documents. Most of the research works are focused on extraction of concepts and taxonomic...

Predicted habitat shifts of Pacific top predators in a changing climate
Climate change scenarios predict an average sea surface temperature rise of 1–6 °C by 2100. Now, a study investigating the potential effect of these changes on the distribution and diversity of marine top pred...

Effect of matrix habitat on the spread of flea beetle introductions for biological control of leafy spurge
Matrix habitats are known to influence the movement patterns of a variety of species but it is less well known whether these effects have strong implications for spatial population dynamics, including the spre...

The influence of matrix habitat on Aphthona flea beetle immigration to leafy spurge patches
Variation in movement ability by insects among different non-habitat (matrix) types may have important implications for both metapopulation dynamics and weed biocontrol practices. We used a mark-recapture expe...
