Major progress has been made towards a global target on protected and conserved area coverage set in 2010, but commitments on the quality of these areas have fallen far short, according to a new report from the UN and IUCN.
Invasive alien species - harmful species introduced by human activity to an area in which they are not native - are estimated to cost the African agricultural sector $3.66 trillion per year - approximately 1.5 times the gross domestic product of all African countries combined. The findings are published in the open access journal CABI Agriculture and Bioscience.
Blocked blood vessels in the brains of stroke patients prevent oxygen-rich blood from getting to cells, causing severe damage. Plants and some microbes produce oxygen through photosynthesis. What if there was a way to make photosynthesis happen in the brains of patients? Now, researchers reporting in ACS' Nano Letters have done just that in cells and in mice, using blue-green algae and special nanoparticles, in a proof-of-concept demonstration.
Cornell University scientists have worked with the University of California, Davis, to identify the DNA markers that determine grape flower sex. In the process, they also pinpointed the genetic origins of the perfect flower.
The wild relatives of modern peanut plants have the ability to withstand disease in ways that peanut plants can't. Researchers at the University of Georgia have been homing in on the genetics of those wild relatives to make use of the advantageous ancient genes.
Five years after a disastrous wildfire in Fort McMurray, Alberta, researchers are warning that the complex role of peatlands, a factor critical to projecting the risk and behaviour of future fires, is missing from the forecasting model.
Fields of opium poppies once bloomed where the Zurich Opera House underground garage now stands. Through a new analysis of archaeological seeds, researchers at the University of Basel have been able to bolster the hypothesis that prehistoric farmers throughout the Alps participated in domesticating the opium poppy.
In the quest for more sustainable agriculture, engineered crops that tackle photorespiration, a highly energy-consuming process, hold enormous potential. Researchers from the EU-funded Gain4Crops project have now succeeded in engineering a solution that connects photorespiration and C4 metabolism, two of the main targets in plant metabolism. This first proof of concept opens the door to strategic crops with improved productivity and reduced consumption of resources.
A new study led by Russ Van Horn, Ph.D., takes the most detailed look yet at the dens of this species. Van Horn, a population sustainability scientist, leads San Diego Zoo Wildlife Alliance's Andean bear conservation program. He was joined by colleagues from the University of British Columbia's Department of Forest and Conservation Sciences and the Spectacled Bear Conservation Society. The study's findings may aid conservation planners in locating den sites or guiding management for suitable bear habitat.
University of California scientists have discovered genetic data that will help food crops like tomatoes and rice survive longer, more intense periods of drought on our warming planet.
