Pygoscelid penguins breeding distribution and population trends at Lions Rump rookery, King George Island
Abstract Long term changes (46 years) in the abundance of pygoscelid penguins breeding populations and nests distribution in the Lions Rump (King George Island) colony were in− vestigated in three time intervals, according to previously published two censuses and one original study conducted in 2010...
