Kids love to play in the dirt. So Flagstaff ecologist Anita Antoninka is channeling that love into learning… using it as a way to teach kids about the effects of climate change on the earth’s biocrust. Today, she’s working with a seventh grade science class at Northland Preparatory Academy to see how a warming planet affects moss.

Scientists are dismissing a popular theory about mass extinction since the last ice age. The Younger Dryas Impact Hypothesis contends an asteroid hit Earth 13,000 years ago changing the climate instantly and dramatically. Scott Anderson, a paleoecologist at Northern Arizona University, is part of an international research team that looked for evidence to support this explanation, but didn't find any.

Bach and Mozart have one. ZZ Top has one. And of course all of The Beatles have them. They are asteroids.

Auto exhaust at the Grand Canyon may be ruining more than just the view; it might be harming native plants, in particular. The National Park Service wants to know just how harmful excess nitrogen is to the ecosystem, so they offered a grant to soil ecologist Nancy Johnson at Northern Arizona University. Her study involved taking samples of soil, air and pinyon pine needles at the heavily trafficked South Rim.

More than 170 different kinds of bees are pollinating plants in Arizona’s high elevation forests. Flagstaff ecologist Lindsie McCabe wants to know what will happen to them as global temperatures warm. She’s conducting experiments with bees on the San Francisco Peaks, simulating the impact of climate change on native pollinators.
