Hungry polar bears are increasingly a threat to seabirds in the Canadian Arctic than traditional "outlaws" like foxes and gulls, researchers say in a study conducted in Canada. Polar bears are already seven times more likely to visit colonies of birds in the area of Hudson Strait between rockport tx northern Quebec and Baffin Island, than in 1980, showing more study. It shows that increased predation is closely related to the shrinking of the Arctic ice during the season, which is almost two months shorter than it was 30 years ago. "Significant areas of open water that are typical for May, already with less ice, and land on which they depend polar bears has changed dramatically," says the study. Polar bears use the ice as a platform for hunting seals - their favorite food, but resorted to eating eggs and everything else you can find when the ice melts. "Debeloklyunestite birds that nest on the cliffs, they have one goal. Even more vulnerable are large sea ducks because lay 3-4 eggs in a nest on the ground, "said Samuel Iverson biologist at the University" Carlton ", lead author of the study. Scientists have discovered that the bears - usually rockport tx a single or females with cubs have fallen about 34% of the down colonies. Gulls, which usually can not get anything from birds mothers tend to join when bears begin to crush the eggs. Researchers say that the destruction is usually done quickly and often leads to "almost complete reproductive failure" for seabirds, which incubate only one egg per season. The study found that visits the Bears have risen sharply in the nesting places for the period of 24 years. Before bears roamed the colonies a day or at most two of the season. "What we see now is close to 12 days a season," Iverson rockport tx informed in an interview. He believes that a more thorough evaluation of the "storage" of birds. "I definitely think this is a big problem," he concludes.
Faith must be a priority. She held us in bondage, we would have preserved and is now on the decline and degradation that we see everywhere. But this would happen only if that belief has it. And this does not depend on anyone else but ourselves. Learn more
