A study out of The USDA Agricultural Research Service at the University of Wisconsin has evaluated the response of diverse carrot germplasm to salinity stress, identified salt-tolerant carrot germplasm that may be used by breeders, and defined appropriate screening criteria for assessing salt tolerance in germinating carrot seed.
Researchers have developed a new approach to map huckleberry distribution across Glacier National Park that uses publicly available satellite imagery. Tracking where huckleberry plants live can help biologists predict where grizzly bears will also be found.
Visible imagery from NASA's Terra satellite showed Tropical Cyclone Joaninha as it moved through the Southern Indian Ocean triggering warnings in the island nation of Mauritius.
Early on March 26, Tropical Cyclone Veronica continued to move along the coast of Western Australia and NASA-NOAA's Suomi NPP satellite provided a visible image of the storm that showed the storm was stripped of strong thunderstorm development around the center.
A team of researchers has tested how each gene within the genome of rice--one of the world's most important staple crops--senses and responds to combinations of water and nutrients.
Many insect pollinator species are disappearing from areas of Great Britain, a new study has found. Research led by the Centre for Ecology & Hydrology showed one third of wild pollinator species experienced declines in terms of areas in which they were found, while one tenth increased.
The Paris Agreement set goals of keeping global temperature rise below 2.0°C and working to keep that rise to 1.5°C to mitigate impacts of climate change. To predict how these temperature rises will intensify the hydrologic cycle, researchers developed a new metric that reflects dry and wet spell intensity and conducted multi-model ensemble experiments. The scenario with 0.5°C more warming showed significantly greater intensification. Disaster risks could be substantially reduced by reaching the 1.5°C target.
Land conservation modestly increases employment rates, a traditional indicator of economic growth, according to an analysis of New England cities and towns, led by scientists at Amherst College, Harvard Forest, the Highstead Foundation, and Boston University.
The greening or eutrophication of the world's lakes will increase the emission of methane into the atmosphere by 30 to 90 percent during the next 100 years, say authors of a March 26, 2019 paper in Nature Communications. This increased methane emission is equivalent to 18-33 percent of annual carbon dioxide emissions from burning fossil fuels. Limiting lake greening is important to preserve fragile water supplies and to avoid acceleration of climate change.
In a recently published study, UA ecologists have identified the bets that the most successful annual plants place with water resources.
