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.

  1. Historic plane rediscovered

    Antarctica The first ever plane to make it to Antarctica has been rediscovered as the continent’s ice cover continues to melt.

    The 1911 Vickers monoplane was found by Australian workers restoring the Mawson Huts explorers’ outpost on the Antarctic coast.

    Worker David Jenson said that although there was no evidence that the plane had actually flown over the continent – instead being used on the ground to pull supplies – it was still “a historic find.”

    “And it wouldn’t have been found if the ice cover wasn’t as low as it’s ever been,” he added.

  2. Old camera parts found in the Antarctic

    Cape Denison, Antarctica – An Antarctic expedition has found what they believe to be camera parts abandoned by a renowned Australian photographer during a historic trip to the frozen continent nearly a century ago.

    James “Frank” Hurley, who died in 1962, was the official photographer of the 1911-14 Australasian Antarctic Expedition (AAE) led by the country’s most famous polar explorer Sir Douglas Mawson. He was also the official photographer of the Australian armed forces during both World Wars.

    Members of the current expedition, which is dedicated to restoring Mawson’s original wooden huts at Cape Denison, said they had retrieved a plate-changing box from a Newman and Guardia camera dating back to between the late 19th to early 20th centuries, inside Hurley’s dark room.

    “We’re not 100-percent sure if it’s a component of Hurley’s camera’s yet, as we are waiting on verification, however it’s definitely a component of a very old camera used here in Antarctica which in itself makes it an interesting find,” expedition member and archaeologist Jody Steele told Reuters.

    Several Newman and Guardia cameras were part of the equipment used by the AAE. Details of the recent find have been sent back to Australia for more investigation.

    “This is a significant discovery because it may be one of the few camera parts that we can identify with an individual member of the AAE, Frank Hurley,” expedition member Peter Morse said.

    “Other artefacts are more general by nature where as this is specific with a member of the expedition”.

    The find has been returned to its dark room, where the cold environment has helped to preserve it so far.

    On New Year’s Day, the expedition found what it believes to be the remains of the first aeroplane brought to Antarctica on an icy shore near where it was abandoned almost a century ago by Mawson after it proved to be a failure during his expedition.

    Australia had searched for many years for the old single-propeller Vickers plane at Cape Denison, and expedition members stumbled on pieces of rusted metal tubing on the shore of Commonwealth Bay during very low tide which match structural iron tubing from the single-winged plane’s fuselage. – Reuters
