Responses of Antarctic Marine and Freshwater Ecosystems to Changing Ice Conditions
© 2016 The Author(s) 2016. Polar regions are warming more rapidly than lower latitudes, and climate models predict that this trend will continue into the coming decades. Despite these observations and predictions, relatively little is known about how polar ecosystems have responded and will continue...
