Beneath the Antarctic sea-ice: Fine-scale analysis of Weddell seal (Leptonychotes weddellii) behaviour and predator-prey interactions, using micro-sonar data in Terre Adélie ...
In this study, we tried to assess:i) whether and how female Weddell seals feed (frequency, depth, duration) during lactation,ii) what is their utilization of a limited foraging area (benthic or pelagic dives) as they are spatially constrained by the presence of their pup, andiii) how can we characte...
