7. STRONG EFFECTS OF ENVIRONMENTAL CONDITIONS ON REPRODUCTIVE SUCCESS OF PENGUINS AT KING GEORGE ISLAND

   variability in the reproductive success of Adélie, gentoo, and chinstrap penguins can be explained by simple ... reproductive success in all species. Biological variables measured during the chick-rearing phase, like krill ... chinstrap penguins which breed later in the season than gentoo and Adélie penguins.
