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 FranΓ§ois Leroy and Petr Keil! Using the Breeding Bird Survey, we document not only a continent-wide decline in bird abundance since the 1980s β€” but, crucially, the acceleration of these declines over time. www.science.org/doi/10.1126/...

Global bias towards recording latitudinal range shifts - Nature Climate Change The authors consider studies reporting species range shifts and demonstrate a geometric bias in sampling along latitudinal, rather than longitudinal, gradients. This bias may favour the corroboration ...

Study area shape matters when tracking species range shifts & we may underestimate longitudinal range shifts to the benefit of latitudinal range shifts, potentially undermining drivers other than T°C 🌑

Multiple Early Career Faculty Positions in Ecology
 
The Department of Biological Sciences at the University of Notre Dame invites applications for multiple, tenure-track assistant professor positions that will enhance existing institutional excellence in ecology. We are searching broadly for creative and collaborative individuals (1) working at any spatial scale, from local to global, in any system, (2) studying any level of biological organization, from genes to ecosystems, and (3) using any mode of inference, from empirical to theoretical. Applicants should demonstrate research excellence that crosses traditional disciplinary boundaries; ongoing growth in the department will emphasize new hires that use quantitative and/or integrative approaches to study ecological processes. Postdoctoral experience is desirable in applicants. Successful candidates will engage with and benefit from UNDERC, Notre Dame’s 8000-acre environmental field station and home to NEON’s Great Lakes domain, superb on-campus chemical and genomic analytical facilities, an experimental research facility located close to campus, cross-disciplinary interactions through multiple centers and institutes including the Environmental Change Initiative, and a unique Interdisciplinary Graduate Training Program in Environment and Society. New faculty will benefit from Notre Dame’s recent campus-wide Strategic Framework that included the Just Transformations to Sustainability Initiative. Modern research facilities exist in a new environmental research building, which opened in 2025.
