Q&A: Colwell on cracking the biodiversity code

April 12, 2017

Robert Colwell, adjoint curator in entomology at the Museum of Natural History on campus, has a paper published today in Methods in Ecology and Evolution on using novel mathematical approaches to estimate the number of fish species on coral reefs. We caught up with him to discuss his lifelong fascination with the Earth’s biodiversity, and his latest research, which could be applied to any species.

Local efforts appear to be helping bumblebee populations

April 12, 2017

None of the 22 native species of bumblebees in Boulder County showed declines over a recent five-year period, according to a new CU Boulder study. Two species previously believed to be disappearing were present in several locations. "It shows that Boulder County is doing something right," the study authors say.

Humans have dramatically increased extent, duration of wildfire season

Feb. 27, 2017

Humans have dramatically increased the spatial and seasonal extent of wildfires across the U.S. in recent decades and ignited more than 840,000 blazes over a 21-year period, according to new University of Colorado Boulder-led research.

Long-term ecological study to continue at very special site, Niwot Ridge

Feb. 22, 2017

Thanks to a six-year $6.8 million renewal grant, decades-long data collection will continue on Niwot Ridge. It is the only site of its kind on the continent comprising alpine and sub-alpine environments, and CU Boulder researchers sometimes brave harsh weather conditions to get there.

Coal mine dust hastens Arctic snow melt

Feb. 1, 2017

Dust released by an active coal mine in Svalbard, Norway, reduced the spectral reflectance of nearby snow and ice by up to 84 percent, according to new University of Colorado Boulder-led research.

Colorado's wildfire-stricken forests showing limited recovery

Jan. 30, 2017

A study of Front Range forests burned by wildfires between 1996 and 2003 shows they are not regenerating as well as expected and large portions may become grasslands or shrub lands in coming years.

Recent storms recouped 37 percent of California’s five-year snow-water deficit

Jan. 27, 2017

The recent “atmospheric river” weather pattern that pummeled California with storms from late December to late-January may have recouped 37 percent of the state’s five-year snow-water deficit.
