Drier summers and a decline in average snowpack over the past 40 years have severely hampered the establishment of spruce and fir trees in Colorado's Front Range.
Increased temperatures caused localized extinction of a common Rocky Mountain flowering plant, a result that could serve as a herald of future population declines.
Chemical products like household cleaners, pesticides, paints and perfumes now rival motor vehicle emissions as the top source of urban air pollution, according to a surprising NOAA-led study.
The first-ever molecular evidence of obligate symbiosis in lichens could shed new light on how and why some multicellular organisms consolidate their genomes in order to co-exist.
The changing topography of ice sheets in the Northern Hemisphere during the last Ice Age forced changes in the climate of Antarctica, a previously undocumented inter-polar climate change mechanism.
Compiling the first global atlas of soil bacteria, researchers have identified a group of around 500 key species that are both common and abundant worldwide.
Study: Birds nesting near noisy oil and gas operations had changes in stress hormones similar to those in people with PTSD. Also, some laid fewer eggs or had chicks with stunted growth.
CU Boulder researchers contributed to a new report that prioritizes Earth science research to reduce climate uncertainty, improve weather forecasts and more.
New research shows that a long-held hypothesis about the factors that govern species ranges largely holds true, but may be the result of a previously underappreciated ecological mechanism.
