the coming of summer in June in the Rocky Mountains, United States, always marked by the development of a variety of wildflowers. Pasture in the mountains it festive with colorful flowers.
But the "party" The summer will not last forever. The scientists found a number of wildflowers, which was originally developed throughout the season, is now reduced. In mid-season no longer found a blooming flower. The findings were published in the latest Journal of Ecology.
"The shift in the flowering season mountain meadows may affect a resource for animal pollinators like bees," said David Inouye of the University of Maryland.
Biologists neighborhood with his partner, George Aldridge and William Barr of the Rocky Mountain Biological Laboratory, Jessica Forrest of the University of California at Davis, and Abraham Miller-Rushing of the USA National Phenology Network in Tucson, found that such a change would more often be found in line with climate change.
"A number of animal pollinators with short periods of activity may require only a flower of one species," they said, "but requires a pollinator is active throughout the season of flowers in sufficient quantities all the time."
Animals important pollinators, such as beetles, for example, require pollen and nectar supply throughout the growing season so that the queen can produce a colony. When the summer temperatures warm places like Elk Mountains in Colorado, the scientists found that the decline is widespread interest in the ecosystem.
"The meadow was greatly influenced by melting snow and temperatures," said Inouye. "Wild flowers using the information shown by nature to know when to arrive as they develop petalnya."
Climate at the beginning of this summer's drier and warmer in the high areas such as southern Rocky Mountains. These changes alter the conditions of humidity and time of flowering in the meadow. Inouye says the change is causing a decline in the number of wildflowers that bloom.
Flowering season changes that occur in a wide area can have serious consequences for the entire population of the animal pollinators. "Not just bees, but also hummingbirds and other animals that consume pollen and nectar," Inouye said.
In the long run, the change will affect plants require animal pollinators. If the bees and hummingbirds need flowers, plants and flowers also need bees humming.
