Late Holocene colonisation of snow petrels (Pagodroma nivea) of the Prince Charles Mountains, Antarctica
The effect of long-term environmental changes on sea bird populations with respect to changes in their breeding and foraging habitats is difficult to assess due to the scarcity of records that go beyond direct observational data. Information on the past distribution of snow petrel Pagodroma nivea (F...
