Team studies greenhouse gas emissions from Appalachian streams

Freshwater ecosystems can be substantial sources of greenhouse gases to the atmosphere, but it can be difficult to figure out how unique aquatic habitat arrangements and connections influence carbon cycling at different scales.

Analysis finds US ecosystems shifting hundreds of miles north

Whole ecosystems are shifting dramatically north in the Great Plains, a phenomenon likely linked to human influences such as climate change, says new University of Nebraska-Lincoln research that analyzed nearly 50 years' ...

Mount Kilimanjaro: Ecosystems in global change

2019 marks the 250th anniversary of Alexander von Humboldt. He was one of the first naturalists to document the distribution and adaptation of species on tropical mountains in the 19th century. Humboldt also observed that ...

Researchers make a key discovery on how alpine streams work

An EPFL study has prompted scientists to rethink a standard approach used to calculate the velocity of gas exchange between mountain streams and the atmosphere. Research conducted in streams in Vaud and Valais indicate that ...

Health checkups for alpine lakes

The best tool for assessing the health of mountain lakes comes in a very small package. According to new research by University of Alberta biologists, alpine species of zooplankton are excellent bioindicators of lake health. ...

Tropical mountain species in the crosshairs of climate change

Lack of varied seasons and temperatures in tropical mountains have led to species that are highly adapted to their narrow niches, creating the right conditions for new species to arise in these areas, according to a new study ...
