TL;DR: Current and expected changes in ASO physical habitats in response to climate change are reviewed, including how these changes may impact the autecology of marine biota: microbes, zooplankton, salps, Antarctic krill, fish, cephalopods, marine mammals, seabirds, and benthos.

TL;DR: The number of African penguins breeding in South Africa collapsed from about 56 000 pairs in 2001 to some 21 000 pairs by 2009, a loss of 35 000 pairs (>60%) in eight years as discussed by the authors.

TL;DR: Tracking data from 17 marine predator species in the Southern Ocean is used to identify Areas of Ecological Significance, the protection of which could help to mitigate increasing pressures on Southern Ocean ecosystems.
Journal ArticleDOI

TL;DR: The results support suspending fishing when prey biomass drops below critical thresholds and suggest that mitigation of marine ecological traps will require matching conservation action to the scale of ecological processes.
Journal ArticleDOI
