Global Connectivity of Southern Ocean Ecosystems
Murphy, Eugene J.; Johnston, Nadine M.; Hofmann, Eileen E.; Phillips, Richard A.; Jackson, Jennifer A.; Constable, Andrew J.; Henley, Sian F.Southern Ocean ecosystems are globally important. Processes in the Antarctic atmosphere, cryosphere, and the Southern Ocean directly influence global atmospheric and oceanic systems. Southern Ocean biogeochemistry has also been shown to have global importance. In contrast, ocean ecological processes are often seen as largely separate from the rest of the global system. In this paper, we consider the degree of e...
The retrospective analysis of Antarctic tracking data project
Ropert-Coudert, Yan; Van de Putte, Anton P.; Reisinger, Ryan R.; Bornemann, Horst; Charrassin, Jean-Benoît; Costa, Daniel P.; Danieli, BrunoThe Retrospective Analysis of Antarctic Tracking Data (RAATD) is a Scientific Committee for Antarctic Research project led jointly by the Expert Groups on Birds and Marine Mammals and Antarctic Biodiversity Informatics, and endorsed by the Commission for the Conservation of Antarctic Marine Living Resources. RAATD consolidated tracking data for multiple species of Antarctic meso- and top-predators to identify A...
A framework for mapping the distribution of seabirds by integrating tracking, d...
Carneiro, Ana Paula B.; Pearmain, Elizabeth J.; Oppel, Steffen; Clay, Thomas A.; Phillips, Richard A.; Bonnet‐Lebrun, Anne‐Sophie; Wanless, Ross M.1. The identification of geographic areas where the densities of animals are highest across their annual cycles is a crucial step in conservation planning. In marine environments, however, it can be particularly difficult to map the distribution of species, and the methods used are usually biased towards adults, neglecting the distribution of other life-history stages even though they can represent a substantia...
Framework for mapping key areas for marine megafauna to inform Marine Spatial P...
Augé, Amélie A.; Dias, Maria P.; Lascelles, Ben; Baylis, Alastair M.M.; Black, Andy; Boersma, P. Dee; Catry, Paulo; Crofts, Sarah; Galimberti, FilippoMarine Spatial Planning (MSP) is becoming a key management approach throughout the world. The process includes the mapping of how humans and wildlife use the marine environment to inform the development of management measures. An integrated multi-species approach to identifying key areas is important for MSP because it allows managers a global representation of an area, enabling them to see where management can...
Sexual and individual foraging segregation in Gentoo penguins Pygoscelis papua ...
Xavier, José C.; Trathan, Philip N.; Ceia, Filipe R.; Tarling, Geraint A.; Adlard, Stacey; Fox, Derren; Edwards, Ewan W. J.; Vieira, Rui P.Knowledge about sexual segregation and gender-specific, or indeed individual specialization, in marine organisms has improved considerably in the past decade. In this context, we tested the "Intersexual Competition Hypothesis" for penguins by investigating the feeding ecology of Gentoo penguins during their austral winter non-breeding season. We considered this during unusual environmental conditions (i.e. the ...
