Defining criteria for the reintroduction of locally extinct populations based on contemporary and ancient genetic diversity: The case of the Adriatic Beluga sturgeon ( Huso huso)
Abstract Aim The restoration of the extinct Adriatic population of Beluga sturgeon, an iconic species with economic and traditional relevance, is a priority in upcoming conservation strategies but it must not occur without deep prior knowledge on the current diversity distribution. We defined inform...
