Scientists have discovered that grasses are able to short cut evolution by taking genes from their neighbors.
More than half of the carbon sink in the world's forests is in areas where the trees are relatively young -- under 140 years old -- rather than in tropical rainforests, research at the University of Birmingham shows.
To help smallholder farmers adapt to climate change, scientists need to provide recommendations of crop varieties suitable to farmers' marginal and heterogeneous environments. However, existing on-farm approaches are difficult to scale. A novel scalable method using crowdsourced citizen science was employed on 12,409 trial plots in Ethiopia, India and Nicaragua. The results showed the potential of crowdsourced citizen science to improve variety recommendations and help farmers respond to climate change.
Thomas Crowther, ETH Zurich identifies long-disappeared forests available for restoration across the world. In his AAAS session, Crowther describes how such an effort, could absorb as much as 135 gigatons of atmospheric carbon. Crowther will also describe data from thousands of soil samples collected by local scientists that reveal the world's most abundant population of soil organisms in arctic and sub-arctic regions and the most dominant populations of plants and animals in tropical regions.
Recent advances to address hunger through agricultural discovery will be highlighted at this year's annual meeting of the AAAS. Session speaker and University of Illinois professor Donald Ort will discuss the global food security challenge and a recent breakthrough in Science that boosted crop growth by 40 percent by creating a shortcut for a glitch that plagues most food crops.
The key to breeding disease-resistant honeybees could lie in a group of genes -- known for controlling hygienic behaviour -- that enable colonies to limit the spread of harmful mites and bacteria, according to genomics research conducted at York University. The researchers narrowed in on the 'clean' genes known to improve the colony's chance of survival. The finding was published today in the journal Genome Biology and Evolution.
While previous studies showed elk often move into areas disturbed by fires or timber harvest to take advantage of new plant growth, that isn't happening in Wyoming's Sierra Madre Mountains, where elk strongly avoid beetle-killed areas in the summer.
A new study by researchers at the Max Planck Institute for Plant Breeding Research (MPIPZ) in Cologne has revealed that a previously unappreciated structural feature underlies the ability of the plant immune molecule EDS1 to provide a timely defense boost against pathogens.
Aloe sanguinalis, or Somali Red Aloe, forms large, conspicuous clumps and has blood red sap. Its clumps can easily be spotted from the road, but the species has only just been named and described in the open access journal PhytoKeys.
The UPV/EHU's IBeA research group has used a non-destructive methodology to determine the role of specific algae, lichens, mosses, cyanobacteria, etc. that may be causing exfoliation and delamination, which are degrading the Sacred Rock of Machu Picchu, one of the most important symbols in the Peruvian archaeological city.
