Long-term survival despite low genetic diversity in Blackwell Publishing Ltd the critically endangered Madagascar fish-eagle
The critically endangered Madagascar fish-eagle (Haliaeetus vociferoides) is considered to be one of the rarest birds of prey globally and at significant risk of extinction. In the most recent census, only 222 adult individuals were recorded with an estimated total breeding population of no more tha...
