🐺📈 Avec @milleretcyril.bsky.social et Christophe Duchamp, nous venons de mettre à jour les estimations de survie et effectifs de la population de loups en France pour l'hiver 2023/2024, tout est là hal.science/hal-05016361v1

@ofbiodiversite.bsky.social @cnrsecologie.bsky.social
Variations da la probabilité de survie lors de 3 périodes (1995-2013 ; 2014-2018 ; 2019-2024). Les barres représentent les bornes hautes et basses de l’intervalle de confiance à 95%, et la barre horizontale noire, les estimations moyennes. Le seuil de tolérance moyen est de 34% de mortalité (soit 66% de survie) est donné (pointille rouge) avec son intervalle de confiance (en grisé ; Marescot et al. 2012). Des taux des survies en dessous de cet intervalle présentent donc un risque important de générer des taux de croissance négatifs de la population (selon Marescot et al. 2012). Les taux de survie sont présentés après avoir pris en compte l’effet transient sur la survie (Pradel et al. 1997). Tendance démographique de la population de loups en France estimée par modèles de capture recapture et à partir du suivi génétique non-invasif. Les barres représentent les estimations basses et hautes des intervalles de confiance à 95% des effectifs chaque hiver depuis 1995/96. La valeur moyenne des estimations est représentée par une barre horizontale blanche. Les valeurs utilisées dans cette figure sont disponibles dans le Tableau S1.

Le Faucon crécerellette est l'un des rapaces les plus rares de France. Il a fait l'objet d'un programme de réintroduction dans l'Aude et des individus en provenance d'Espagne ont permis de renforcer la population nicheuse.

In the 1990s, >80% of Portuguese white storks were winter migrants. Thirty years on, a drastic shift in behavior means most individuals are now residents.

Our new paper @animalecology.bsky.social combines census data, GPS tracking, and genomics to understand the loss of migratory behavior in birds:
Mechanisms underlying the loss of migratory behaviour in a long‐lived bird
White stork populations in Iberia are undergoing a profound change in their migratory patterns, becoming mostly resident. By combining census data, GPS-tracking and genomic analyses, Andrade et al. l....

A call to arms for eBirders and iNaturalists. 🚨

We want your bird photos! If you photograph feeding birds with flowers, fruit, seeds or prey, upload the image with locality details. We are data-harvesting species, size and type of food/prey to study foodwebs and species interactions. Thanks! 🧪🌐🪶

A study in Nature suggests that the Atlantic Meridional Overturning Circulation (AMOC) may be able to withstand future global warming and could avoid collapse. This important ocean current has a role in regulating temperatures around the planet. https://go.nature.com/4blFMKA 🧪
