From British daily The Morning Star:
Penguin mapping plan to aid climate scientists
Monday 14 December 2009
Genetic “featherprints” are being used to map the movements of penguins to see how they are affected by global warming, scientists have said.
Scientists have found genetic markers in DNA from collected feathers that can help them track Antarctic penguins as they migrate between colonies.
They hope the technique will reveal whether climate change is driving the birds from their favoured breeding sites.
The DNA allows scientists to determine the relatedness of birds within a colony, enabling them to follow the movements of individuals and populations.
The markers have already been used to make a population map of macaroni penguins around South Georgia.
Genetic tracking is now being extended to all penguin species on the Antarctic peninsula.
Zoological Society of London scientist Dr Tom Hart said: “Knowing how penguins are responding to climate change is vital to conservation efforts.
“If we understand how their populations are changing, we can do something about it, such as making sure that our protected areas are in the right place for penguins in 100 years’ time.”

ScienceDaily (Dec. 21, 2009) — All insect-eating migratory birds who winter in Africa and breed in the Dutch woods have decreased in numbers since 1984. This has been revealed by research conducted by the University of Groningen, the SOVON Dutch Centre for Field Ornithology, Statistics Netherlands (CBS), Radboud University Nijmegen and Alterra, published on 16 December in the Proceedings of the Royal Society B: Biological Sciences: here.
