How climate change could disrupt the dance between wildflowers and bees, according to a CU study

It’s a snapshot of climate change in action: Plants and pollinators on the slopes of one of Colorado’s most famous mountains are falling out of sync with one another.

Researchers say rising temperatures and early snowmelt atop Pikes Peak are causing some noticeable shifts in the ecosystem and throwing off some important life cycles.

Wildflowers on the mountain are blooming earlier, and pollinators like bees and butterflies are emerging at different times. And that’s concerning because we rely on pollinators to make our crops grow.

Julian Resasco, an associate professor of ecology and biology at the University of Colorado Boulder studied these cycles with a team of researchers. The findings were published last month in American Naturalist.

He joined Erin O’Toole to discuss what the researchers found, and how the work began with a study from a century ago looking at flowers and bees in the same area of Pikes Peak.

KUNC's In The NoCo is a daily slice of stories, news, people and issues. It's a window to the communities along the Colorado Rocky Mountains. The show brings context and insight to the stories of the day, often elevating unheard voices in the process. And because life in Northern Colorado is a balance of work and play, we celebrate the lighter side of things here, too.
As the host of KUNC’s news program and podcast In The NoCo, I work closely with our producers and reporters to bring context and diverse perspectives to the important issues of the day. Northern Colorado is such a diverse and growing region, brimming with history, culture, music, education, civic engagement, and amazing outdoor recreation. I love finding the stories and voices that reflect what makes NoCo such an extraordinary place to live.
