The Southern Ocean around Antarctica is among the most rapidly warming regions on Earth, but has experienced episodic climate change during the past 40 million years. It remains unclear how ancient periods of climate change have shaped Antarctic biodiversity. The origin of antifreeze glycoproteins (AFGPs) in Antarctic notothenioid fishes has become a(More)
Antarctic notothenioids represent one of the few strongly supported examples of adaptive radiation in marine fishes. The extent of population connectivity and structure is unknown for many species, thereby limiting our understanding of the factors that underlie speciation dynamics in this radiation. Here, we assess the population structure of the widespread(More)
