Cumulative human impacts across the world's oceans are considerable. We therefore examined a single model taxonomic group, the penguins (Spheniscidae), to explore how marine species and communities might be at risk of decline or extinction in the southern hemisphere. We sought to determine the most important threats to penguins and to suggest means to mitigate these threats. Our review has relevance to other taxonomic groups in the southern hemisphere and in northern latitudes, where human… 
Global terrestrial distribution of penguins (Spheniscidae) and their conservation by protected areas
Establishing protected areas (PAs) ranks among the top priority actions to mitigate the global scale of modern biodiversity declines. However, the distribution of biodiversity is spatially asymmetric
Happy Feet in a Hostile World? The Future of Penguins Depends on Proactive Management of Current and Expected Threats
Penguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 of the 18 penguin species are decreasing.
Marine Ecosystem Assessment for the Southern Ocean: Birds and Marine Mammals in a Changing Climate
The massive number of seabirds (penguins and procellariiformes) and marine mammals (cetaceans and pinnipeds) – referred to here as top predators – is one of the most iconic components of the
Important areas and conservation sites for a community of globally threatened marine predators of the Southern Indian Ocean
In the Southern Ocean, the impact of environmental changes and increasing human encroachment is causing declines in several populations of seabirds. Amsterdam island (77°33′E; 37°50′S) hosts some
A Review of Plastic-Associated Pressures: Cetaceans of the Mediterranean Sea and Eastern Australian Shearwaters as Case Studies
Impacts of debris on marine fauna occur throughout the marine ecosystems, with adverse impacts documented on over 1,400 species; impacts can be divided into those arising from entanglement, and those
The influence of historical climate changes on Southern Ocean marine predator populations: a comparative analysis.
TLDR
Comparative palaeoecological studies are a valuable source of long-term data on species' responses to environmental change that can provide important insights into future climate change responses, and this synthesis highlights the importance of protecting productive foraging grounds proximate to breeding locations.
Marine Important Bird and Biodiversity Areas for Penguins in Antarctica, Targets for Conservation Action
Global targets for area-based conservation and management must move beyond threshold-based targets alone and must account for the quality of such areas. In the Southern Ocean around Antarctica, a

Penguins as Marine Sentinels
TLDR
These temperate penguin species, marine sentinels for southern oceans, demonstrate that new challenges are confronting their populations as increases in precipitation and reductions in sea ice associated with climate warming are affecting penguins.
Seabird conservation status, threats and priority actions: a global assessment
TLDR
Overall, seabirds are more threatened than other comparable groups of birds and that their status has deteriorated faster over recent decades, while on land, alien invasive predators, habitat degradation and human disturbance are the main threats.
King penguin population threatened by Southern Ocean warming
TLDR
It is shown that warm events negatively affect both breeding success and adult survival of this seabird, and suggest that king penguin populations are at heavy extinction risk under the current global warming predictions.
Penguin responses to climate change in the Southern Ocean
Penguins are adapted to live in extreme environments, but they can be highly sensitive to climate change, which disrupts penguin life history strategies when it alters the weather, oceanography and
Climate change and the Antarctic marine ecosystem: an essay on management implications
TLDR
It is suggested that industries with the greatest potential to aggravate climate change impacts on marine communities are marine capture fisheries, and it will be important to prioritize issues that reduce impacts and uncertainties by the greatest degree.
Spatially integrated assessment reveals widespread changes in penguin populations on the Antarctic Peninsula.
TLDR
Results from integrated analyses confirm that Pygoscelis adeliae (Adélie Penguins) are decreasing at almost all locations on the Antarctic Peninsula and unambiguously establish that P. antarctica (Chinstrap Penguins), thought to benefit from decreasing sea ice, are instead declining regionally.
Wide Range of Mercury Contamination in Chicks of Southern Ocean Seabirds
TLDR
The present work helps selecting some seabird species as sentinels of environmental pollution according to their high Hg concentrations and their contrasted foraging ecology, to monitor the temporal trend of global Hg contamination.
Climate Change Increases Reproductive Failure in Magellanic Penguins
TLDR
Climate change that increases the frequency and intensity of storms results in more reproductive failure of Magellanic penguins, a pattern likely to apply to many species breeding in the region.
A stable isotopic investigation into the causes of decline in a sub‐Antarctic predator, the rockhopper penguin Eudyptes chrysocome
TLDR
Overall, d 13 C signatures decreased significantly over time in rockhopper penguins from seven breeding sites, supporting the hypothesis that decreases in primary productivity, and hence, carrying capacity, have been associated with the decline of penguin populations.
