Some animals won't adapt to climate change

11-13-2006 · EurekAlert!

In a fascinating study appearing in the November issue of the American Naturalist, biologists investigated the response of small animals to climate change on a remote sub-Antarctic Island. From an evolutionary standpoint, acclimatizing to a change in circumstances seems to make evolutionary sense. However, Steven Chown and Jacques Deere (both of Stellenbosch University) found that terrestrial animals don't adapt. Why not?

  1. Climate change could trigger 'boom and bust' population cycles leading to extinction
    04-16-2007 · EurekAlert!
    Climate change could trigger "boom and bust" population cycles that make animal species more vulnerable to extinction. Dramatic population fluctuations make species more vulnerable to extinction due to disease, inbreeding and other causes; in addition, each crash reduces the genetic diversity of a species, lowering its ability to adapt and making it more prone to extinction.

  2. Latest IPCC report highlights need for integrated climate/human behavior models
    04-06-2007 · EurekAlert!
    How can humans adapt to climate change without adding even more stress to the environment? Scientists are now looking at ways to integrate the human dimension of climate change -- the choices we need to make to adapt to a changing global climate -- with the sophisticated climate prediction models used for the IPCC Assessment Reports. The goal: To evaluate the best ways forward.

  3. Tropical plants go with the flow ... of nitrogen
    05-07-2007 · EurekAlert!
    Tropical plants are able to adapt to environmental change by extracting nitrogen from a variety of sources, according to a new study. By demonstrating that not all plants specialize in one specific source of nitrogen, the result turns a commonly held theory on its head. It also provides a dose of optimism that tropical forests will be able to withstand environmental shifts in nutritional cycles brought on by global climate change.

  4. Mosquito genes explain response to climate change
    04-23-2007 · EurekAlert!
    University of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate -- and are apparently evolving -- in animals in response to climate change. The map will allow researchers to narrow their focus to identify specific genes that control the seasonal development of animals.

  5. Want to monitor climate change? P-p-p-pick up a penguin!
    04-03-2007 · EurekAlert!
    We are used to hearing about the effects of climate change in terms of unusual animal behavior, such as altering patterns of fish and bird migration. However, scientists at the University of Birmingham are trying out an alternative bio-indicator -- the king penguin -- to investigate whether they can be used to monitor the effects of climate change.

  6. Age is more than a number -- In barn owls, it reveals how susceptible one is to climate change
    01-10-2007 · EurekAlert!
    Fluctuations in weather and the environment affect survival and reproduction of animals. But are all individuals within a population equally susceptible? Theory on the evolution in age-structured populations suggests not -- those life stages that are more important for overall fitness should be less susceptible to environmental variation than other life stages.

  7. Dung happens and helps scientists
    02-15-2008 · EurekAlert!
    A scientist at Northern Arizona University is in charge of the largest animal dung collection in the world, used for clues about animal evolution and extinction, Ice Age existence and climate change. Researcher Jim Mead admits it is a bizarre resource, but he is one of many around the globe who access dung for DNA information. Mead, a dung authority, continues to grow the collection with specimens from as far away as Siberia.

  8. Ocean's 'twilight zone' may be a key to understanding climate change
    04-27-2007 · EurekAlert!
    A major study sheds new light on the role of carbon dioxide once it's transported to the oceans' depths. The research indicates that instead of sinking, carbon dioxide is often consumed by animals and bacteria and recycled in the "twilight zone," a dimly lit area 100 to 1,000 meters below the surface.

  9. Stanford researchers say climate change will significantly increase impending bird extinctions
    12-05-2007 · EurekAlert!
    Where do you go when you've reached the top of a mountain and you can't go back down? It's a question increasingly relevant to plants and animals, as their habitats slowly shift to higher elevations, driven by rising temperatures worldwide. In one of the first analyses of extinction rates to incorporate the most recent climate change scenarios set forth in the IPCC 2007 reports, Stanford researchers say that by 2100 up to 30 percent of land-bird species may be extinct.

    Countering Charles Darwin's view that evolution occurs gradually, UC-Irvine scientists have discovered that plants with short life cycles can evolutionally adapt in just a few years to climate change.
