Morphometric and genetic evidence for four species of gentoo penguin
Abstract Gentoo penguins ( Pygoscelis papua ) are found across the Southern Ocean with a circumpolar distribution and notable genetic and morphological variation across their geographic range. Whether this geographic variation represents species‐level diversity has yet to be investigated in an integ...
