More Arctic sea ice is entering the North Atlantic Ocean than before, making it increasingly dangerous for ships to navigate those waters in late spring, according to new research led by the University of Manitoba.

Nature is rife with symbiotic relationships, some of which take place out of sight, like the rich underground exchange of nutrients that occurs between trees and soil fungi.

Scientists calculate ‘speed limit’ for pumping pollutant to hungry algae, bacteria.

After a 100-year flood struck south central Oklahoma in 2015, a study of the insects, arthropods, and other invertebrates in the area revealed striking declines of most invertebrates in the local ecosystem, a result that researchers say illustrates the hidden impacts of natural disasters.

They might seem like unlikely allies, but ranchers and prairie conservationists have a future working together.

More than a decade after beekeepers first raised the alarm about a dangerously low global bee population, much progress has been made in understanding the mystery of colony collapse.

The new Arctic Now product developed by the Finnish Meteorological Institute shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow.

More accurate maps of bed topography reveal physical processes controlling retreat.

The mountains of East Africa are a treasure trove of biodiversity. However, their ecosystems may be at a higher risk than previously realized. Dr. Andreas Hemp and Dr. Claudia Hemp have discovered that Mount Kilimanjaro is turning into an "ecological island". Agriculture and housing construction have eliminated the natural vegetation that used to serve as a bridge to the surrounding area, enabling the diversity of species to develop to its current levels. Neighbouring mountain regions are presumably also being isolated from their surrounding areas. The researchers have published their study in the journal Global Change Biology.

Homeowners concerned about the decline of bees, butterflies and other pollinating insects need look no further than their own back yards, says ecologist Susannah Lerman at the University of Massachusetts Amherst and the USDA Forest Service. In new research, she and colleagues suggest that homeowners can help support bee habitat in suburban yards, specifically their lawns, by changing lawn-mowing habits.
