Underestimation of avian diversity in the Tumbesian hotspot: Sampling gaps and conservation challenges

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...
