Major natural carbon sink may soon become carbon source

Tue, 20 Nov 2018 07:36:35 EST ~ Peatlands in some parts of the world, including Canada, Siberia and Southeast Asia, have already turned into significant carbon sources. The same fate may be coming soon for the Peruvian peatlands. Find out more...

Hidden giants in forest soils

Mon, 19 Nov 2018 13:31:56 EST ~ Only a fraction of the microbes residing in, on and around soils have been identified through efforts to understand their contributions to global nutrient cycles. Soils are also home to countless viruses that can infect microbes, impacting their ability to regulate these global cycles. Giant virus genomes have been discovered for the first time in a forest soil ecosystem. Find out more...

PNW woodlands will be less vulnerable to drought, fire than Rocky Mountain, Sierra forests

Fri, 16 Nov 2018 14:00:00 EST ~ Forests in the Pacific Northwest will be less vulnerable to drought and fire over the next three decades than those in the Rocky Mountains and Sierra Nevada, computer modeling shows. Find out more...

Climate change/biodiversity loss: Inseparable threats to humanity that must be addressed together

Thu, 15 Nov 2018 14:49:49 EST ~ Demand for biofuels to fight climate change clouds the future for biodiversity. The demand could cause a 10- to 30-fold expansion of green energy-related agricultural land use, adding crushing pressure on habitat for plants and animals and undermining the essential diversity of species on Earth.

Presence of textile microfibers from washing machines in marine floors

Thu, 15 Nov 2018 11:53:55 EST ~ A study quantifies the presence of textile microfibers in south European marine floors. Researchers analyzed the amount of these colored fibers, which vary between 3 to 8 mm but are extremely fine, with less than a 0.1 mm diameter, and which come mainly from washing machines. The results show the dominance of cellulosic fibers over synthetic polymers, and highlight several oceanographic processes pile and transport microfibers to marine hollows. Find out more...

Competition for shrinking groundwater

Wed, 14 Nov 2018 14:43:12 EST ~ Groundwater, which has been used to irrigate crops, satiate livestock and quench thirst in general for thousands of years, continues to be a vital resource around the world. Find out more...

Tropical trees in the Andes are moving up -- toward extinction

Wed, 14 Nov 2018 13:20:22 EST ~ In the most comprehensive study of its kind, biologists have found that tropical and subtropical forests across South America's Andes Mountains are responding to warming temperatures by migrating to higher, cooler elevations, but probably not quickly enough to avoid the loss of their biodiversity, functional collapse, or even extinction. Find out more...

Large areas of the Brazilian rainforest at risk of losing protection

Wed, 14 Nov 2018 13:20:17 EST ~ Up to 15 million hectares of the Brazilian Amazon is at risk of losing its legal protection, according to a new study. Find out more...

Carbon goes with the flow

Tue, 13 Nov 2018 14:17:55 EST ~ Many people see the carbon cycle as vertical -- CO2 moving up and down between soil, plants and the atmosphere. However, new research adds a dimension to the vertical perspective by showing how water moves massive amounts of carbon laterally through ecosystems -- especially during floods. These findings -- which analyzed more than 1,000 watersheds, covering about 75 percent of the contiguous US -- have implications for climate change and water quality. Find out more...

Business as usual for Antarctic krill despite ocean acidification

Tue, 13 Nov 2018 08:09:30 EST ~ A new study has found that Antarctic krill are resilient to the increasing acidification of the ocean as it absorbs more C02 from the atmosphere due to anthropogenic carbon emissions. Krill are one of the most abundant organisms on Earth and a critical part of the Southern Ocean marine ecosystem. Find out more...
