Wrongly ID’d since ’74, Only Three Specimens Known
Collectors found the first two specimens of the prickly plant in 1974 and 1990 in west Texas. Then, for two decades, the 14-inch-tall plant was identified wrongly as one species, then another and then a third. (more…)
New Food Bank program makes local produce accessible to low-income community
“We want to make sure you have access to the best produce,” says University of Delaware anthropology senior Dan Reyes. “To locally-, naturally- and organically-grown fruits and vegetables. Pesticide-free. Herbicide-free. The kinds of food normally too expensive to buy in grocery stores.”
The kinds of food that low-income households can now — thanks to the Food Bank of Delaware’s Community Supported Agriculture (CSA) program, developed by two UD students — purchase using their federal food benefits. (more…)
*Plant lineages with multiple copies of their genetic information face higher extinction rates than their relatives, researchers report in Science magazine.*
While duplication of hereditary information is a relatively rare event in animal evolution, it is common in plants. Potatoes, coffee, bananas, peanuts, tobacco, wheat, oats and strawberries, to name but a few, all carry multiple copies of their genetic material, in a condition called polyploidy.
In contrast, most animals including humans are diploid, meaning an individual carries only two copies of each chromosome, the carriers of genetic information, one from each parent. (more…)
GAINESVILLE, Fla. — Over the past two decades, Florida cattle ranchers have spent as much as $16 million a year doing battle with an invasive weed called tropical soda apple, known as TSA, that takes over pastures, elbowing out the forage grasses ranchers need for their cattle.
But a beetle released by the University of Florida’s Institute of Food and Agricultural Sciences is taking a bite out of the problem by feeding on the weed and reducing its competitiveness. UF researchers describe the beetle’s success as a biological control agent in the current issue of the journal Florida Entomologist. (more…)
