Journal ArticleDOI
Linking movement and dive data to prey distribution models: new insights in foraging behaviour and potential pitfalls of movement analyses
Katie R. N. Florko,Courtney R. Shuert,William W. L. Cheung,Steven H. Ferguson,Ian D. Jonsen,David A. S. Rosen,U. Rashid Sumaila,Travis C. Tai,David Zurakowski,Marie Auger-Méthé +9 more
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
Ian D. Jonsen,Clive R. McMahon,Toby A. Patterson,Marie Auger-Méthé,Robert Harcourt,Mark A. Hindell,Sophie Bestley +6 more
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
W. James Grecian,Garry B. Stenson,Martin Biuw,Lars Boehme,Lars P. Folkow,Pierre Goulet,Ian D. Jonsen,Aleksander Malde,Erling S. Nordøy,Aqqalu Rosing-Asvid,Sophie Smout +10 more
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.
