Taxonomic and Biogeographic Misconceptions in Qinling Lenok (Brachymystax tsinlingensis): Reassessing Zhou et al. (2025) Species Distribution Models

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Brachymystax tsinlingensis is an endangered teleost fish species endemic to China's Qinling Mountains. Zhou et al.'s (2025) study contains two critical flaws: taxonomic misidentification and spatial extrapolation errors, thereby compromising biogeographic accuracy and risking distributional misinterpretations. We propose targeted enhancements—including

ABSTRACT How species adapt to diverse environmental conditions is essential for understanding evolution and the maintenance of biodiversity. The European cisco (Coregonus albula) is a salmonid that occurs in both fresh and brackish water, and this together with the presence of sympatric spring‐ and autumn‐spawning lacustrine populations provides an ...
