Changes and consistencies in marine and coastal bird numbers on Kidney Island (...
Catry, Paulo X; Clark, T. J.; Crofts, Sarah; Stanworth, Andrew J.; Wakefield, EwanDetecting change is necessary for effective ecosystem management, yet temporal data on key ecosystem components are lacking for many polar and subpolar regions. For example, although the Falkland Islands hosts internationally important marine and coastal bird populations, few of these were surveyed until the late twentieth century. The avifauna of one small island, Kidney Island, was surveyed between 1958 and 1...
Genomics detects population structure within and between ocean basins in a circ...
Rexer-Huber, Kalinka; Veale, Andrew; Catry, Paulo; Cherel, Yves; Dutoit, Ludovic; Foster, Yasmin; McEwan, John C.; Parker, Graham C.; Phillips, RichardThe Southern Ocean represents a continuous stretch of circumpolar marine habitat, but the potential physical and ecological drivers of evolutionary genetic differentiation across this vast ecosystem remain unclear. We tested for genetic structure across the full circumpolar range of the white-chinned petrel (Procellaria aequinoctialis) to unravel the potential drivers of population differentiation and test alte...
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...
DNA Metabarcoding as a Marine Conservation and Management Tool: A Circumpolar E...
McInnes, Julie C.; Jarman, Simon Neil; Lea, Mary-Anne; Raymond, Ben; Deagle, Bruce E.; Phillips, Richard A.; Catry, Paulo; Stanworth, Andrew J.Almost all of the world’s fisheries overlap spatially and temporally with foraging seabirds, with impacts that range from food supplementation (through scavenging behind vessels), to resource competition and incidental mortality. The nature and extent of interactions between seabirds and fisheries vary, as does the level and efficacy of management and mitigation. Seabird dietary studies provide information on p...
High occurrence of jellyfish predation by black-browed and Campbell albatross i...
McInnes, Julie C.; Alderman, Rachael; Lea, Mary-Anne; Raymond, Ben; Deagle, Bruce E.; Phillips, Richard A.; Stanworth, Andrew J.; Thompson, David R.Gelatinous zooplankton are a large component of the animal biomass in all marine environments, but are considered to be uncommon in the diet of most marine top predators. However, the diets of key predator groups like seabirds have conventionally been assessed from stomach content analyses, which cannot detect most gelatinous prey. As marine top predators are used to identify changes in the overall species comp...
