Genetic footprint of population fragmentation and contemporaneous decline in the endangered Yangtze finless porpoise
Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies. Here, we examined the extent of population structure and recent evolution of the critically endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorien...

Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies.
