AbstractIn wild animals, the length of their telomeres, the noncoding DNA sequences protecting the ends of chromosomes, in early life has been shown to predict their performance (e.g., survival, repro...

Olivier Chastel travels to Svalbard in northern Norway to study the impact of contaminants such as mercury on black-legged kittiwakes.

We investigated sources of variation in eight egg characteristics capturing the colour, spottiness, shape, and size of 1589 eggs from 687 clutches produced by 330 female common terns (Sterna hirundo)...

With my colleagues Romain Pigeault and Jérôme Moreau we offer a 6-months internship position for a master student (2nd year) about the potential effect of pesticides on passerine birds. Check the atta...

Très utilisé dans l'agriculture, ce fongicide se révèle diablement efficace pour nuire à la reproduction des oiseaux. Les toxicologues ont beau alerter la Commission……

Bird species with higher plasma glucose show comparatively lower albumin glycation, suggesting the evolution of glycation resistance mechanisms, and terrestrial carnivores present higher glycation tha...

Mercury (Hg) is a pollutant that does not only biomagnify along the food chain, but can also accumulate in long-lived top-predators, such as many seab…

Abstract. Animal species exhibit a wide range of coloration and patterns, which are under strong selection and often linked to individual quality, influenc

There’s a lot we get wrong about our least favorite seabirds

Coastal ecosystems face salinization and rising temperatures. In coastal ectotherms, salinity and temperature affect metabolism, tolerance, infections, growth, behavior, and survival. Overall, the combined effects of salinity and temperature on species distribution, community structure, invasive species, and ecosystem functioning need to be fully assessed to understand impacts from these stressors.

Salinization is predicted to intensify due to climate change, impacting biodiversity and ecosystem functioning. Amphibians, particularly embryos and l…
