Tundra disappearing at rapid rate

...slow because conditions are so harsh at these high latitudes and altitudes," said Dr. Ryan Danby, from the Department of Biological Sciences. "But what our data indicates is that there was an upslope surge of trees in response to warmer temperatures. It’s like it waited until conditions were just right and the...

Tropical forests -- Earth's air conditioner

...ing snowy tundra." Forests in colder, sub-polar latitudes evaporate less water and are less effective at producing clouds. As a result, the main climate effect of these forests is to increase the absorption of sunlight, which can overwhelm the cooling effect of carbon storage. However, Caldeira believes ...

Evolution of Old World fruit flies on three continents mirrors climate change

...d, is that the chromosome inversions common in low latitudes seemingly provide the flies with protection against warmer temperatures. The genetic composition found in the newest samples corresponded almost exactly to the composition of insects that in earlier studies were collected from sites 70 miles, or 1...

Important gene controlling tree growth and development found

.... This means that trees originating from different latitudes (different origins in the north to south direction, so called "provenances", display different critical daylengths. For instance, an aspen tree from the middle of Germany stops growing and sets buds when the days get shorter than 16 hours. Compare th...

Atmospheric ozone recovering in mid-latitudes, report shows

... occurs in the tropics, but affects ozone in other latitudes because of atmospheric transport. Despite the natural fluctuations, Yang, Cunnold and their co-authors are very confident in the conclusions they reached from the data they analyzed. "We know from the study we've just published that the Montreal Pro...

Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species

...ith differences in ocean temperatures at different latitudes ranging from the tropics to the arctic. The results agreed closely with predictions of their model. "It takes more energy than all the fossil fuel people burn on the planet in a year to form one new species of plankton," said Andrew Allen, Ph.D., th...

Vegetables inhibit growth of prostate cancer in mice with human tumors

...t, whereas the Laysan albatrosses forage at higher latitudes near Alaska. So it appears that the California Current system has significantly higher concentrations of these contaminants," Finkelstein said. The researchers published their findings in the April issue of the journal Ecological Applications. Mer...

Albatross study shows regional differences in ocean contamination

Sociality of sweat bees evolved simultaneously during climate change

... altitude such that species and populations at low latitudes and in warmer regions are often fully social, whereas they are solitary at higher latitudes and altitudes, which are colder." Warmer regions have longer growing seasons, he explained, which ...

2005 was the warmest year in a century

...everywhere at the same time and is largest at high latitudes in the Northern Hemisphere. Over the last 50 years, the largest annual and seasonal warmings have occurred in Alaska, Siberia and the Antarctic Peninsula. Most ocean areas have warmed. Because these areas are remote and far away from major cities, it...

On a wing and a prayer - Alaska researchers seek clues to bird flu

...s of bird flu - strains that could spread to lower latitudes and possibly jump to other species, including humans. University of Alaska (UAF) scientists and state and federal biologists from across Alaska have joined forces and formed the University of Alaska Program on the Biology and Epidemiology of Avian I...

South America's vast pantanal wetland may become next everglades, UNU experts warn

...eratures rise, species will migrate towards higher latitudes and altitudes in both hemispheres, and the species composition and functioning of plants will be altered, particularly the efficiency with which they use water. If the climate changes rapidly, as projected, mismatches may occur between the new clima...
