Emperor penguins and climate change

  title={Emperor penguins and climate change},
  author={Christophe Barbraud and Henri Weimerskirch},
Variations in ocean–atmosphere coupling over time in the Southern Ocean have dominant effects on sea-ice extent and ecosystem structure, but the ultimate consequences of such environmental changes for large marine predators cannot be accurately predicted because of the absence of long-term data series on key demographic parameters. Here, we use the longest time series available on demographic parameters of an Antarctic large predator breeding on fast ice and relying on food resources from the… Expand
Trends in bird and seal populations as indicators of a system shift in the Southern Ocean
Although world oceans have been warming over the past 50 years, the impact on biotic components is poorly understood because of the difficulty of obtaining long-term datasets on marine organisms. TheExpand
Effects of climate change and fisheries bycatch on Southern Ocean seabirds : a review
Over the last century, major climate changes and intense human exploitation of nat- ural living resources have occurred in the Southern Ocean, potentially affecting its ecosystems up to top marineExpand
Contrasted demographic responses facing future climate change in Southern Ocean seabirds.
This is among the first attempts to study the demographic responses for several populations with contrasted environmental conditions, which illustrates that investigating the effects of climate change on core population dynamics is feasible for different populations using a common methodological framework.

King penguin population threatened by Southern Ocean warming
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. Expand
Effects of climate change on an emperor penguin population: analysis of coupled demographic and climate models.
It is concluded that climate change is a significant risk for the emperor penguin and that population declines are far more likely than population increases. Expand
Exploring Linkages between Abiotic Oceanographic Processes and a Top-trophic Predator in an Antarctic Ecosystem
It is shown that over a 30-year period in the Ross Sea, average weaning masses of Weddell seals, Leptonychotes weddellii, varied strongly among years and were correlated to large-scale climatic and oceanographic variations. Expand
Seabird life histories and climatic fluctuations: a phylogenetic‐comparative time series analysis of North Atlantic seabirds
In the light of the predicted changes in climate as a consequence of global warming, it is a major concern how animal species will respond to altered meteorological and oceanographic conditions.Expand
Decadal-scale variation in diet forecasts persistently poor breeding under ocean warming in a tropical seabird
The indirect effect of ocean warming on a top predator, Nazca boobies in the equatorial Galápagos Islands, is forecast, where rising water temperature is expected to exceed the upper thermal tolerance of a key prey item in the future, severely reducing its availability within the Boobies’ foraging envelope. Expand
Demographic models and IPCC climate projections predict the decline of an emperor penguin population
It is shown that the increased frequency of warm events associated with projected decreases in SIE will reduce the population viability and the probability of quasi-extinction and emperor penguins will have to adapt, migrate or change the timing of their growth stages to avoid extinction. Expand
Landfast ice: a major driver of reproductive success in a polar seabird
It was found that longer distances to the LFI edge negatively affected the overall breeding success but also the fledging success, and climate window analyses suggested that chick mortality was particularly sensitive to LFI variability between August and November. Expand


Southern Ocean environmental changes: effects on seabird, seal and whale populations
The main changes in the distribution and abundance of marine top predators in the Antarctic in the last two centuries were caused by an over-exploitation and certain taxa are especially vulnerable to at least some of the likely environmental changes. Expand
Foraging behaviour of emperor penguins as a resource detector in winter and summer
THE emperor penguin (Aptenodytes forsteri), which feeds only at sea, is restricted to the higher latitudes of the antarctic sea-ice habitat1–3. It breeds on the winter fast ice when temperaturesExpand
Ocean circulation off east Antarctica affects ecosystem structure and sea-ice extent
It is proposed that along this coastline ocean circulation determines both the sea-ice conditions and the level of biological productivity at all trophic levels as well as the scales of local surveys and global observations. Expand
Effects of sea-ice extent and krill or salp dominance on the Antarctic food web
Data from 1995 and 1996 are provided that support hypothesized relationships between krill, salps and region-wide sea-ice conditions and suggest that decreased krill availability may affect the levels of their vertebrate predators. Expand
Abrupt mid-twentieth-century decline in Antarctic sea-ice extent from whaling records
A decline in Antarctic sea-ice extent is a commonly predicted effect of a warming climate. Direct global estimates of the Antarctic sea-ice cover from satellite observations, only possible since theExpand
Distribution of surface zooplankton and seabirds across the Southern Ocean
It is suggested that appropriate food availability rather than water temperature is important for the determination of seabird distribution and the ecological importance of the recently described frontal zone associated with the northern boundary of the maximum winter expansion of sea ice is confirmed. Expand
Ecological importance of the Southern Boundary of the Antarctic Circumpolar Current
The association of primary production, Krill, and whales with the Southern Boundary, suggests that it provides predictably productive foraging for many species, and is of critical importance to the function of the Southern Ocean ecosystem. Expand
The foraging location, diving behavior, dietary composition, and feeding rates of female Emperor Penguins from the Auster and Taylor Glacier colonies in Antarctica were investigated during the 1993 austral winter. Expand
An Antarctic circumpolar wave in surface pressure, wind, temperature and sea-ice extent
THE Southern Ocean is the only oceanic domain encircling the globe. It contains the strong eastward flow of the Antarctic Circumpolar Current, and is the unifying link for exchanges of water massesExpand

The length of the sea ice season summarizes in one number the ice coverage conditions for an individual location for an entire year. It becomes a particularly valuable variable when mapped spatiallyExpand
