Historical anthropogenic stressors affect bird ecology and feather development in neotropical forests

Oikos, Volume 2025, Issue 10, October 2025.
Fragmentation and habitat loss driven by agricultural expansion have significantly affected bird ecology. Additionally, the growing use of agrochemicals impacts ecosystems and avian communities. Tools such as isotopic analysis provide reliable proxies for assessing organisms' habitat use and diet, and can also reflect environmental alterations, such as
