Linking movement and dive data to prey distribution models: new insights in foraging behaviour and potential pitfalls of movement analyses

TL;DR: In this paper , the authors assessed the validity of these assumptions by associating horizontal movement and diving of satellite-telemetered ringed seals (Pusa hispida ) in Hudson Bay, Canada, to modelled prey data and environmental proxies.
Journal ArticleDOI

aniMotum, an R package for animal movement data: Rapid quality control, behavioural estimation and simulation

TL;DR: AniMotum as discussed by the authors is an R package that facilitates the tasks of conducting quality control on and inference of changes in movement from animal tracking data via a simple but extensible workflow that accommodates both novice and experienced users; automated processes that alleviate complexity from data processing and model specification/fitting steps; simple movement models coupled with a powerful numerical optimization approach for rapid and reliable model fitting.
Proceedings Article

Mining non-taxonomic concept pairs from unstructured text: a concept correlation search framework

TL;DR: The proposed framework has been tested with the Fisheries Oceanography journals, and the results demonstrate significant improvements over traditional association rule approach in search of non-taxonomic concept pairs.

Movement responses to environment: fast inference of variation among southern elephant seals with a mixed effects model

TL;DR: In this paper, the authors apply new fast-estimation tools to fit mixed effects within a random walk movement model, rapidly inferring among-individual variability in southern elephant seal environment-movement relationships.
Journal ArticleDOI

Environmental drivers of population-level variation in the migratory and diving ontogeny of an Arctic top predator

TL;DR: How migratory and dive behaviour develop over the first year of life for a migratory Arctic top predator, the harp seal Pagophilus groenlandicus, is assessed using animal-borne satellite relay data loggers to highlight the role of both intrinsic and extrinsic factors in shaping early life behaviour.
