Satellite imagery shows seasonal changes to American deciduous forests from space.

Social networking, even between competing species, plays a much bigger role in ecology than anyone previously thought, according to three biologists at the University of California, Davis.

Although concentrations of chemicals and pollutants like salt and nutrients have increased in the deep waters of Lake George, they’re still too low to harm the ecosystem at those depths, according to an analysis of nearly 40 years of data published today in Limnology and Oceanography.

Scientists have developed artificial intelligence that can identify 200 species of birds from just a single photo, offering another way to quickly and cheaply monitor bird populations than the traditional in-person counts often used today.

New technology developed by engineers at the University of Alberta shows potential in cleaning and decontaminating process water from oilsands production.

Kudzu and emerald ash borer are widely known examples of an invasive plant and an invasive insect, respectively, that cause harm to our native plants.
