Concentration of dinitrogen oxide – also referred to as nitrous oxide – in the atmosphere increases strongly and speeds up climate change. In addition to CO2 and methane, it is the third important greenhouse gas emitted due to anthropogenic activities.

A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where nighttime skyglow is an increasing environmental disturbance.

Food waste is one of the most important issues of current food systems: Food and Agriculture Organization (FAO) has estimated that more than one third of food is either lost or wasted along the entire food supply chain causing significant economic, social and environmental impacts.

As species across the world adjust where they live in response to climate change, they will come into competition with other species that could hamper their ability to keep up with the pace of this change, according to new CU Boulder-led research.

Watch as UNBC biologist Dr. Roy Rea and his team of student researchers spent the summer of 2020 combing the Macleod Lake Mackenzie Community Forest north of Prince George collecting moose droppings.

For the last decade, chinook salmon, commonly known in Alaska as “king salmon,” has been in decline, a trend that has stumped researchers and biologists across the state as to what is causing the salmon’s low returns.

Thousands of vessels, from enormous cargo ships to much smaller fishing boats, annually traverse the waters around Alaska.

With demand for lentils growing globally and climate change driving temperatures higher, a University of Saskatchewan (USask)-led international research team has developed a model for predicting which varieties of the pulse crop are most likely to thrive in new production environments

The final frontier is getting messy. Debris -- including defunct satellites, abandoned fuel tanks, tools dropped by astronauts and fragments from satellite collisions.

After a dry summer and despite a few recent rainy days, Connecticut is experiencing an increasingly dry autumn, with areas of the state ranging from abnormally dry to extreme drought conditions.
