Where have all the flowers gone?
Date:6/16/2011

It's summer wildflower season in the Rocky Mountains, a time when high-peaks meadows are dotted with riotous color.

But for how long?

Once, wildflower season in montane meadow ecosystems extended throughout the summer months. But now scientists have found a fall-off in wildflowers at mid-season.

They published their results, funded by the National Science Foundation (NSF), in the current issue of the Journal of Ecology.

"Shifts in flowering in mountain meadows could in turn affect the resources available to pollinators like bees," says David Inouye of the University of Maryland, currently on leave in NSF's Division of Environmental Biology.

Inouye and colleagues 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, Ariz., found that such changes could become more common as climate change progresses.

"Some pollinators with short periods of activity may require only a single flower species," write the ecologists in their paper, "but pollinators active all season must have flowers available in sufficient numbers through the season."

For example, bumblebees, important pollinators in many regions, need a pollen and nectar supply throughout the growing season to allow the queen bee to produce a colony.

As mid-summer temperatures have warmed in places like the Elk Mountains of Colorado, the researchers have found that the mid-season decline in flowering totals is ecosystem-wide.

"These meadows are heavily affected by snowmelt and temperature," says Inouye. "Wildflowers use information from these natural cues to 'know' when it's time to unfurl their petals."

The early-season climate is becoming warmer and drier in the high altitudes of the southern Rocky Mountains.
