Genetic diversity in a unique population of dugong (Dugong dugon) along the sea coasts of Thailand

Abstract Dugong (Dugong dugon) populations have been shrinking globally, due in large part to habitat fragmentation, degradation and ocean pollution, and today are listed as Vulnerable by the IUCN. Thus, determining genetic diversity in the remaining populations is essential for conservation plannin...
