Long‐term within‐basin isolation patterns, different conservation units, and interspecific mitochondrial DNA introgression in an amphipod endemic to the ancient Lake Skadar system, Balkan Peninsula

Investigation of biodiversity, including genetic diversity within species, is crucial for rational planning of nature conservation and species protection. Endemics or narrow‐ranged taxa, sensitive to alteration of physical and chemical conditions, may serve as local bioindicators. Homoeogammarus scutarensis is an endemic, cold‐adapted amphipod crustacean, inhabiting fragmented spring habitats, within a relatively small area of the Lake Skadar...
