Southwest forests may decline in productivity on average as much as 75 percent over the 21st century as climate warms. The finding is based on a treasure trove of about 20,000 unanalyzed tree cores discovered in a Utah laboratory about a decade ago. The University of Arizona-led research team published their findings in the Dec. 17 issue of Nature Communications.
A new study published in Nature Ecology and Evolution presents a novel approach to identify optimal priority areas for restoration, considering multiple criteria such as biodiversity conservation, climate change mitigation and reduction of costs. In a context of multiple local, national and global targets for ecosystem restoration, the study presents a flexible tool capable of increasing restoration cost-effectiveness by up to eight times.
The biodiversity catalogue of the Iberian Peninsula spiders is now adding the discovery of a dozen new species -from seven different families- that are mainly found in edaphic environments (soil), according to an article led by Professor Miquel Àngel Arnedo, from the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona.
Scientists say more should be done to tackle the growing environmental impact of takeaway food containers. A new study estimates there are 2025 million takeaway containers per year being used in the European Union (EU) alone. It also says finding a way to recycle disposable takeaway containers could help reduce equivalent greenhouse gas emissions generated annually by 55,000 cars.
New research shows that the powerful sense of smell Pacific salmon rely on for migration, finding food and avoiding predators might be in trouble as carbon emissions continue to be absorbed by the ocean.
Despite the looming ecological consequences, glacier motion remains poorly understood. The bedrock, the ice-bed interface and the water-filled cavities all affect friction and influence how the ice will flow, but studying these poses challenges -- remote radar sensing can track glacial movement, but it can't measure detailed properties of the ice and rock. In the Journal of Chemical Physics, Bo Persson describes a new model of ice friction that offers crucial insight into glacier flows.
To counteract the damage hurricanes have caused to their canopies, trees appear to adjust key characteristics of their newly grown leaves, according to a year-long field study presented at the British Ecological Society's annual conference today.
Researchers asked more than 1,000 participants in a nationally-representative sample to rate the energy used -- and the greenhouse gas emitted -- by the production of one serving of 19 different kinds of food, and by using one of 18 different appliances for one hour. Participants underestimated the environmental impacts of appliances and food production, but they underestimated the impacts of food significantly more than those of appliances.
Consumers greatly underestimate the energy consumption and greenhouse gas emissions associated with their food choices, but they'll favor items with a lower carbon footprint if they're given clear information on the label, according to new research from the University of Technology Sydney and Duke University.
Climate change could have devastating effects on vulnerable residents in the Andes mountains and the Tibetan plateau, according to researchers at The Ohio State University who have been studying glaciers in those areas for decades.
