Surveying Adelie Penguins in Antarctica

From Our Changing World, 9:55 pm on 17 February 2011

Adelie penguins are an iconic Antarctic species, and as one of the Antarctic's most 'easily observable organisms' they have been the focus of long-term surveys.

Phil Lyver from Landcare Research explains to Alison Ballance how a combination of aerial photography and ground-based monitoring are revealing population trends and evolutionary insights that are in turn being used in climate models to predict the impact of rising temperatures and changing sea ice regimes on Antarctic species.

They spoke at Scott Base, in November 2010, just before the annual aerial census of Adelie penguin colonies on Ross Island and along the Victoria land coast.
