New research from a multi-university team of biologists shows what could be a startling drop in the amount of carbon stored in the Sierra Nevada mountains due to projected climate change and wildfire events.
The loss of intact forest cover in Myanmar has accelerated over the last decade, according to a study published May 17, 2017 in the open-access journal PLOS ONE by Peter Leimgruber from Smithsonian Conservation Biology Institute, United States of America; Ned Horning from American Museum of Natural History, United States of America; and colleagues.
Central American tropical forests are beginning to disappear at an alarming rate, threatening the livelihood of indigenous peoples there and endangering some of the most biologically diverse ecosystems in North America. The culprit? Cocaine.
A new analysis of Yellowstone grizzly bear diets reveals that grizzlies in the region continue to feed upon the products of an endangered tree species currently declining at the hands of climate change. Such changes are forcing some bears to look for more varied food sources. The researchers say the results call for increased monitoring efforts in the region.
Keeping habitats connected, so that species can move in response to environmental change, is crucial to ecosystem resilience, according to researchers from McGill University and University of British Columbia.
New research in Brazil has found that rivers in the Amazon emit far more carbon dioxide (CO2) than previously estimated, suggesting that the Amazon Basin is closer to net carbon neutral. The results increase the most recent global estimates of CO2 emissions from rivers and lakes by almost 50 percent, with potentially huge implications for global climate policy.
Warming temperatures are prompting some tree species in the Rocky Mountains to 'migrate' to higher elevations in order to survive. Researchers at the University of Tennessee, Knoxville, have discovered that tiny below-ground organisms play a role in this phenomenon -- and could be used to encourage tree migration in order to preserve heat-sensitive species. Their work shows how these invisible biotic communities create 'soil highways' for young trees, meaning they could determine how quickly species march uphill, if at all.
The ability of some Western conifer forests to recover after severe fire may become increasingly limited as the climate continues to warm, scientists from the Smithsonian Conservation Biology Institute (SCBI) and Harvard Forest found in a new study published today in Global Change Biology.
For the first time, scientists have created a global map measuring the cooling effect forests generate by regulating the exchange of water and energy between the Earth's surface and the atmosphere. The information offers a valuable new tool in efforts to mitigate climate change, according to an article recently published in the journal Nature Climate Change.
Indigenous Peoples, local communities from 30 different countries are demanding respect for their land rights. Despite clear evidence that communities are the best guardians of their lands and the world's forests -- highlighted in a new policy brief -- governments are giving the go-ahead to dams, coal mines, palm oil plantations, and other projects that rob the forests' customary owners of their homes and livelihoods, and threaten the climate and resources we all depend on.
