Genetic homogeneity in face of morphological heterogeneity in the harbor porpoises from the Black Sea and adjacent waters

Y. Ben Chehida, J. Thumloup, K. Vishnyakova, P. Gol'din, M. C. Fontaine

The paper investigates genetic structure in Black Sea harbor porpoises and finds near-complete genetic homogeneity despite morphological heterogeneity, suggesting potential for cryptic population subdivision.

Genetic footprint of Population Fragmentation and Contemporaneous Decline in the endangered Yangtze Finless Porpoise

M. Chen, M. C. Fontaine, Y. Ben Chehida, J. Zheng, F. Labbe, Z. Mei, Y. Hao, K. Wang, M. Wu, Q. Zhao, D. Wang

The paper analyzes genetic data from Yangtze finless porpoises to show population fragmentation, low genetic diversity, and recent decline linked to habitat degradation and human activity.
