Comparison of emperor penguin declines between Pointe Géologie and Haswell Island over the past 50 years
International audience The emperor penguin (Aptenodytes forsteri) is highly dependent on sea ice conditions, and future climate change may affect its distribution and numbers. Most studies on the demography and population dynamics of emperor penguins in relation to sea ice characteristics were condu...
