Phylogeography and genetic diversity of the critically endangered Przewalski's gazelle
Abstract The Przewalski's gazelle ( Procapra przewalskii ) is critically endangered and has experienced significant decline in population numbers in the past, and now survives in four isolated populations: the Bird Island, Hudong‐Ketu, Yuanzhe and Shadao‐Gahai populations. To understand better...
