Chenyang presents at AGU 2025

Chenyang presents two talks at the 2025 AGU conference. First, he shared his ongoing research on linking bird occurrence to vertical vegetation structure across the United States. In his second talk, he stepped in for Colin Sweeney, who was unable to attend, to present our collaborative work comparing airborne laser scanning (ALS) and GEDI LiDAR in their ability to capture vegetation structure and its effects on bird diversity. Way to go, Chenyang!

Research team on avian diversity and vegetation structure gathers in Columbus

Collaborators from The Ohio State University, the University of Wisconsin–Madison, and the Cornell Lab of Ornithology met in Columbus to review progress and plan future work. This NSF-funded project aims to understand how vegetation complexity—quantified using LiDAR—shapes the assembly of bird communities. We had a great time brainstorming new ideas and developing exciting directions for future projects.

Reymond defends his Masters thesis!

Reymond has successfully defended his Masters thesis on seasonal variation in avian functional distinctiveness across the globe. His work delves into what makes bird species unique at both local and global scales, how these species-level distinctiveness values affect assemblage-level distinctiveness, and how this all changes across seasons. Congrats, Reymond! You made us proud!

New preprint: Spatial and seasonal variation in avian dietary strategies

New preprint! André, Reymond, and Marta publish a global-scale assessment of the seasonality of dietary space and its environmental drivers. We show strong seasonal variation in birds’ dietary space at both the assemblage and species levels globally, with the most pronounced intra-annual dietary shifts occurring in the temperate and boreal regions of the Northern Hemisphere.
