How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
My research interests focus on investigating marine predators' responses in the face of global changes within their habitats. I'm currently investigating spatial and social ecology of the threatened St. Lawrence beluga as part of my PhD project.
As extreme weather is expected to become more frequent with global climate change, it is crucial to evaluate the capacity of species to respond to short-term and unpredictable events. Here, we examined the effect of a strong storm event during the chick-rearing stage of little penguins (Eudyptula minor) from a mega colony in southern Australia. We...
Southern Ocean ecosystems are extremely vulnerable to sea-ice changes occurring at different spatial and temporal scales. Variability in the sea-ice conditions strongly influence the survival and reproduction of animals that are synchronized with the seasonality of sea ice. Although the linkages between Adélie penguins (Pygoscelis adeliae) and sea-...
Humpback whales use the coastal waters of La Réunion Island seasonally from June to October. Their distribution is relatively well-known on the west coast, which provides suitable breeding habitat, however little is known about their use and movement along the south and east coast of the island. Three autonomous acoustic recorders were deployed dur...
As part of my PhD project, I aim to investigate environmental, social and behavioral factors driving habitat selection, movement and fusion-fission dynamics of the threatened St. Lawrence beluga.
At individual level, there are marked differences in the ability of little penguins to encounter/capture prey during their foraging time at sea, Some birds maintain a constant rate of prey encounter during the day, while other fluctuates with time. We hypothesize that these individual differences in daily foraging efficiency could reflect the presence/absence of a thermocline in the foraging zone of the birds and the individual ability of finding these structures. The AIM of this project is to examine within a given year the diving activity, thermal structure of the water column and cumulative prey encounter rate of several individuals at the guard stage (provisioning small chicks within one or two days) using pressure, temperature and accelerometry data recorded by miniature data loggers attached to the birds.
(PI: Christophe BARBRAUD & Yan ROPERT-COUDERT, CEBC) Our main objective is to investigate the behavioural and demographic responses of seabirds and seals to changes in sea ice by combining analyses of foraging data acquired by bio-logging/bio-telemetry techniques and long-term demographic data both in the Arctic and in the Antarctic. In each pole, the project will monitor the foraging and demographic performances of 3 predator species, a flying and a diving seabird and a marine mammal, chosen for their upper position in the food webs and their close association with sea-ice. The project will propose a suite of indicators of sea-ice ecosystem change using seabirds and seals as sentinels of the sea-ice – SENSEI.
