Rapidly warming conditions in the Arctic and the loss of sea ice caused by climate change are driving a steep decline in biodiversity, including among plants, fungi and lichen.
It is widely understood that thawing permafrost can lead to significant amounts of methane being released. However, new research shows that in some areas, this release of methane could be a tenth of the amount predicted from ...
Being common is rather unusual. It's far more common for a species to be rare, spending its existence in small densities throughout its range. How such rare species persist, particularly in an environment undergoing rapid ...
Santa's sleigh is famously pulled by eight reindeer, nine if you include the luminous Rudolf who pitches in when it's foggy. The classic eight are Dasher, Dancer, Prancer, Comet, Cupid, Donner, Vixen and Blitzen. Those last ...
It is the most comprehensive study of its kind to date. Researchers at the University of Bonn and the University of South-Eastern Norway have studied how two characteristic arctic-alpine plant species respond to global warming. ...
Imagine not a white, but a green Arctic, with woody shrubs as far north as the Canadian coast of the Arctic Ocean. This is what the northernmost region of North America looked like about 125,000 years ago, during the last ...
A 15-year experiment on Arctic shrubs in Greenland lends new understanding to an enduring ecological puzzle: How do species with similar needs and life histories occur together at large scales while excluding each other at ...
These days, smoke-filled summer skies and dusky red sunsets are a common occurrence across Canada and the United States. Much of that smoke is coming from large northern wildfires.
The researchers at the Swiss Federal Research Institute WSL used thin sections of roots less than two millimetres thick to identify the tree rings of several hundred spruce (Picea abies), pine (Pinus sylvestris), beech (Fagus ...
University of Virginia terrestrial ecologist Howie Epstein has won a $607,000 NASA grant to use Earth-observing satellite data to assess how vegetation diversity is changing in the Arctic tundra.
