Agricultural policy: Govern our soils
Luca Montanarella calls for a voluntary international agreement to protect the ground beneath our feet from erosion and degradation.
Agriculture: Increase water harvesting in Africa
Meeting global food needs requires strategies for storing rainwater and retaining soil moisture to bridge dry spells
Australia is ‘free to choose’ economic growth and falling environmental pressures
A multi-model framework that accounts for climate, water, energy, food, biodiversity and economic activity in Australia reveals that a sustainable society that enjoys economic improvement without ecological deterioration is possible, but that…
Beauty varies with the light
Experimental work on guppies suggests that variation in light between microhabitats is what makes females prefer different male signal combinations, thus explaining the evolution and persistence of colour variation in males.
Before we drown we may die of thirst
The island nation of Kiribati is one of the world's most vulnerable to rising sea levels. But residents may have to leave well before the ocean claims their homes.
Biodiversity increases the resistance of ecosystem productivity to climate extremes
Data from experiments that manipulated grassland biodiversity across Europe and North America show that biodiversity increases an ecosystem’s resistance to, although not resilience after, climate extremes.
Climate change and the permafrost carbon feedback
A large amount of organic carbon stored in frozen Arctic soils (permafrost) could be released as carbon dioxide and methane in a warming climate, which would accelerate the pace of climate change; this review suggests that release of greenhouse gas…
Decadal slowdown of a land-terminating sector of the Greenland Ice Sheet despite warming
Whether or not an increase in meltwater will make ice sheets move more quickly has been contentious, because water lubricates the ice–rock interface and speeds up the ice, but also stimulates the development of efficient drainage; now, a long-term…
Drought impact on forest carbon dynamics and fluxes in Amazonia
Severe drought in a tropical forest ecosystem suppresses photosynthetic carbon uptake and plant maintenance respiration, but growth is maintained, suggesting that, overall, less carbon is available for tree tissue maintenance and defence, which may…
Erosion of organic carbon in the Arctic as a geological carbon dioxide sink
Robert G. Hilton, Valier Galy, Jérôme Gaillardet, Mathieu Dellinger, Charlotte Bryant, Matt O'Regan, Darren R. Gröcke, Helen Coxall, Julien Bouchez & Damien Calmels
Evolution of endemism on a young tropical mountain
Investigating the evolutionary origins of montane biodiversity by sampling the entire biota from a single mountain, Mount Kinabalu in Borneo, allows for a better understanding not only of the origins of endemism, but also of this biota’s forecasted…
Global carbon export from the terrestrial biosphere controlled by erosion
Particulate organic carbon export from the terrestrial biosphere is primarily controlled by physical erosion, and tectonic and climatic forcing of physical erosion may favour biospheric particulate organic carbon sequestration over silicate…
Global climate agreement: After the talks
The real business of decarbonization begins after an agreement is signed at the Paris climate conference, argue David G. Victor and James P. Leape.
