Knowledge on symbiotic microorganisms of insects has increased dramatically in recent years, yet relatively little data are available regarding non-pathogenic viruses. Here we studied the virome of the parasitoid wasp Anagyrus vladimiri Triapitsyn (Hymenoptera: Encyrtidae), a biocontrol agent of mealybugs. By high-throughput sequencing of viral nuc...
The Vigur Island bird census focused on the main bird species found on the island: Black Guillemots Cepphus grylle, Northern Fulmars Fulmarus glacialis, Great Cormorants Phalacrocorax carbo, gulls Larus sp., Eurasian Oystercatchers Haematopus ostralegus, and Arctic Terns Sterna paradisaea. The Arctic Tern population was estimated by counting nests,...
Abstract Sarracenia insectivorous plants show a diversity of visual features in their pitchers but their perception by insects and their role in attraction, have received little attention. They also vary in prey composition, with some species trapping more flying Hymenoptera, such as bees. To test the hypothesis of a link between visual signal vari...

Ecologists rely on various functional traits when investigating the functioning of ecological systems and its responses to global changes. Changing nutrient levels, for example, can affect taxa expressing different trait combinations in various ways, e.g., favoring small, fast-growing species under high phosphorus conditions. Stoichiometric traits,...
A list of diadromous and marine fishes occurring in the Saint-Pierre and Miquelon archipelago and its eez has been compiled from various available data sources: collections, local and international databases, and literature. this belated work was needed as the only existing checklist dates back to the 19th century and Fishbase, as of early 2022, pr...

La transition agroécologique des systèmes agricoles nécessite la mise en place d’écosystèmes diversifiés favorisant les régulations biologiques. Parmi elles, la pollinisation entomophile assure la reproduction de la majorité des plantes à fleurs et une stabilisation des rendements des cultures. Pour enrayer le déclin des insectes pollinisateurs, le...
The present study aims to characterize the changes of sensitivity of freshwater periphyton over months through the combined measurement of the photosynthetic yield (ΦPSII) and the metabolomics response based on high-resolution mass spectrometry (HRMS).
