Acceleration hotspots of North American birds’ decline are associated with agriculture Human activities might have accelerated declines of population abundance, but this acceleration remains underexplored. Using 1033 North American Breeding Bird Survey routes, we analyze abundance chang...

Thrilled to share our new paper out in @science.org, led by François Leroy and Petr Keil! Using the Breeding Bird Survey, we document not only a continent-wide decline in bird abundance since the 1980s — but, crucially, the acceleration of these declines over time. www.science.org/doi/10.1126/...

11 jours – 239 km – 3 cantons : un loup a fait un périple passionnant. Lors de sa présupposée recherche d’une femelle, il a traversé 3 cantons avant de revenir dans la zone où il se trouvait fin ’25. Il est possible qu’il soit passé par les corridors à faune des cantons de BE et FR. #wolvesandcattle

Les présentations étudiantes ont commencé ! Voici quelques présentateurs sur les thèmes des méthodes émergentes, de l’écologie trophique et de l’écologie microbienne.

Student presentations have started! Here are some on the themes of emerging methods, trophic ecology and microbial ecology

We are thrilled to announce Paolo Crosetto's presentation titled "The Drain of Scientific Publishing: Why Publishing Has Become a Challenge for Science and How It Can Be Improved" in our upcoming PCI Webinar on March 19th at 4 PM (GMT+1)!! 🤩

Le système agricole dominant, fondé sur un usage massif d’intrants chimiques et des productions standardisées tournées vers l’exportation, affecte à la fois la santé humaine et les écosystèmes, sans garantir la viabilité économique des exploitations.

Théo Quant, ça commence ce matin !! 👍

Quel dommage !
On lit (ci-dessous) : Bixi est passé de 250 000 à 700 000 usagers de 2021 à 2025, et a permis 14.5 millions de déplacements à vélo en 2025 (+9% par rapport à 2024).
Son financement passe de 10,5-14 millions/an à 5.5 millions de dollars/an pour 2026-2028.
Absurde !

Huge thanks to the organizers of the 2026 Biennial Conference of The International Biogeography Society in Aarhus (Denmark) last week!
Lots of great inspiring talks and an excellent organization!

Spatial Networks of Habitats, Populations, and Communities: Connecting Approaches to Keep Cutting Edges - Current Landscape Ecology Reports Purpose of review Spatial networks are extensively used in ecology to represent exchanges among landscape features (e.g., habitat patches, river segments) or biological entities (e.g., individuals, po...

New review out in Current Landscape Ecology Reports. I checked whether the use of distinct types of spatial networks in ecology has led to research silos or generated bridges among theoretical frameworks. Find out here: doi.org/10.1007/s408...
And also: Happy New Year 2026!! 😀

Sessions thématiques au programme : Paysages et biodiversité, Géographie des populations, Inégalités territoriales, Analyse des discontinuités spatiales, Géographie théorique et quantitative critique, Réseaux géo-historiques, Géographie des systèmes agricoles

No paper from me or my lab will ever be submitted to an MDPI journal - including any of their superfluous "special issues". I will very rarely (if ever) cite MDPI papers. And I will never review for them. deevybee.blogspot.com/2024/08/gues...

The same goes for FrontiersIn journals, among others.

Spatial Ecology and Conservation Modeling This textbook provides a foundation for modern applied ecology. It follows a rapidly changing field with updates of concepts, methods, and code.

Really happy to share that the Second Edition of our book, "Spatial Ecology and Conservation Modeling", is now out and available online!

We provide a foundation for applied spatial ecology with a focus on learning-by-doing.

@camzoology.bsky.social @conservation.cam.ac.uk

Proud of @emmasbacon.bsky.social who defended yesterday (co-advised @paqlab.bsky.social). 6 months of fieldwork, countless doors knocked on, 28000+ trees IDd, & an incredible MSc thesis on Montréal’s urban forest! While playing in an orchestra & publishing 3 side projects 🤩. Someone hire her ASAP! 😉

Our cover for December! 🦊

Martin et al.(2025) show that species like bobcats, cougars, coyotes, gray foxes, and martens largely avoid each other in space but share surprisingly similar diets—revealing how landscape conditions shape coexistence but also their delicate balance.

@pradeu.bsky.social @alkistiseg.bsky.social Thanks!

Thanks to Thomas Pradeu and the two hosts of today's PhilInBioMed webinar (Sam Scheiner, Alkistis Elliott-Graves) for a great discussion about the impact of philosophy and theoretical thinking on ecology (recording soon online I assume).
I'll stay tuned for the next!

Urban nature based solutions are critical - but often hampered by a lack of collaboration across sectors. How can we do better?

This was such a rewarding project to lead, alongside great colleagues from @environmentca.bsky.social, @treecanada.bsky.social, and many many others.

Happy to share a new publication I contributed to, based on a full day of discussions in MTL on real barriers in cross-sector work. Thanks to Kayleigh Hutt-Taylor for leading it, and to Barbara Frei and @carlyziter.bsky.social for their support. Findings now published in @facetsjournal.bsky.social
