Hamdi Zurqani, an assistant professor of geospatial science for the College of Forestry, Agriculture and Natural Resources and the Arkansas Forest Resources Center at the University of Arkansas at Monticello, developed the Arkansas Vegetation Drought Explorer v.2.0 as part of a drought mapping study. The user-friendly web app gives users access to maps showing drought levels in Arkansas by county, year and month.

Florida manatees are threatened by human activity, but they’re also doing better than ever, according to a study examining manatee populations since 12,000 BC, published November 20, 2024 in the open-access journal PLOS ONE by Thomas J. Pluckhahn of the University of South Florida and David K. Thulman of George Washington University, Washington DC, U.S.

Over a typical two-year rotation of corn and soybeans, 40% of nitrous oxide emissions are in the fertilizer-free soybean year, according to new Iowa State University research. Winter cover crops and planting soybeans earlier could reduce emissions of the potent greenhouse gas by one-third while increasing yields. 

Salk scientists discovered a stretch of DNA in both C3 plants, like wheat and soybeans, and C4 plants, like corn and sorghum, that is responsible for optimizing C4 plant photosynthesis and making them better at withstanding heat and drought. The findings are insightful in understanding how some plants evolved to be more efficient, and may now be used as a springboard for turning C4 photosynthesis on in C3 plants—an important step for creating sustainable crop populations in the face of climate change and a growing global population.
