The Vampyrum spectrum is the largest bat in the Americas, with a three foot wingspan. Wildlife biologist Carol Chambers collects data on the rare animal. She says habitat loss and human disturbance make them particularly susceptible to population decline.

The spring equinox is one of two days a year when the equator lines up with the center of the sun, creating a balance of day and night. Historically – for many indigenous people of the world – this celestial event marks a time for renewal, emergence of life and planting of crops.

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.
