TL;DR: The use of animal telemetry is a powerful tool for observing marine animals and the physical environments that they inhabit, from coastal and continental shelf ecosystems to polar seas and open oceans.

TL;DR: Tracking data from 17 marine predator species in the Southern Ocean is used to identify Areas of Ecological Significance, the protection of which could help to mitigate increasing pressures on Southern Ocean ecosystems.
Journal ArticleDOI
North Atlantic Blue and Fin Whales Suspend Their Spring Migration to Forage in Middle Latitudes: Building up Energy Reserves for the Journey?
Mónica A. Silva,Mónica A. Silva,Rui Prieto,Ian D. Jonsen,Mark F. Baumgartner,Ricardo S. Santos +5 more
TL;DR: Fin whales may alternate periods of active migration with periods of extended use of specific habitats along the migratory route, and a link between fin whales seen in the Azores and those summering in eastern Greenland-western Iceland along a migratory corridor located in central Atlantic waters is shown.
Journal ArticleDOI
Joint estimation over multiple individuals improves behavioural state inference from animal movement data.
TL;DR: It is shown how a joint estimation approach that assumes individuals share identical movement parameters can lead to improved inference of behavioural states associated with different movement processes, especially when location data are error-prone.
Journal ArticleDOI
State-space models' dirty little secrets: even simple linear Gaussian models can have estimation problems.
Marie Auger-Méthé,Chris Field,Christoffer Moesgaard Albertsen,Andrew E. Derocher,Mark A. Lewis,Ian D. Jonsen,Joanna Mills Flemming +6 more
TL;DR: It is demonstrated that even simple linear Gaussian SSMs can suffer from parameter- and state-estimation problems, and it is urged to assess whether the parameters can be estimated accurately before drawing ecological conclusions from their results.
