A general cross-continent model to predict the effects of climate change on savanna vegetation isn’t as effective as examining individual savannas by continent, according to research published in Science this week.
Savannas – grasslands dotted with trees – cover about 20 percent of the earth’s land and play a critical role in storing atmospheric carbon, says Dr. William Hoffmann, associate professor of plant and microbial biology at North Carolina State University and co-author of the study. “We wanted to find out what controls savanna vegetation – essentially the density of trees within the savanna – and whether we can use a single global model to predict what will happen to savannas if global temperatures rise,” Hoffmann said.

Dr. Robert Evans, head of the college’s Department of Biological and Agricultural Engineering, recently was named to the International Drainage Hall of Fame.
Delectable food, musical entertainment and a silent auction featuring unusual plants and an eclectic array of gift items will be showcased at the annual Gala in the Garden at the JC Raulston Arboretum at North Carolina State University. The public event will take place May 4 from 3:30 p.m. to 7 p.m.
The livestock merchandising class gives students the opportunity to learn about and handle livestock and gain hands-on experience planning for, promoting and conducting a livestock auction.
Using projections of water-quality trends based on hundreds of water analyses made during a 40-day period following the release of approximately 39,000 tons of coal ash into the Dan River on Feb. 2, 2014, North Carolina State University soil scientists conclude that the river water is suitable for use as irrigation water on crops and as drinking water for livestock. Researchers caution, however, that flooding, drought conditions or other episodic events in or around the river could change the conditions measurably.
N.C. State University Extension Specialist Dominic Reisig wants to find a way to keep growers with kudzu bug problems out of the “spray continuum.” So he and his colleagues from South Carolina and Georgia will use a $168,644 U.S. Department of Agriculture Southern Regional IPM grant to find out why kudzu bugs leave their home in kudzu patches to move to soybean fields.
Almanac Gardener, a weekly horticulture program of UNC-TV, began its 31st season on April 5. The weekly show features long-time host Mike Gray and N.C. Cooperative Extension horticulture agents sharing information and tips for home gardeners.
I can remember when I was a child several decades ago (we won’t say how many) that my family worried a lot about my grandparents, says host Mary Walden. That wasn’t unusual because living in old age wasn’t easy for many economically. Once they stopped working, older folks had no labor income and pensions were meager. “Has that changed today?” she asks her husband, N.C. State University economist Mike Walden.
