A reversal of fortunes: climate change ‘winners’ and ‘losers’ in Antarctic Peninsula penguins
Climate change is a major threat to global biodiversity. Antarctic ecosystems are no exception. Investigating past species responses to climatic events can distinguish natural from anthropogenic impacts. Climate change produces ‘winners’, species that benefit from these events and ‘losers’, species...
