GAINESVLLE, Fla. – For years, scientists tried to find out why some small streams carry only minute concentrations of nitrogen.
Now Stefan Gerber, a University of Florida researcher with the Institute of Food and Agricultural Sciences, and Jack Brookshire, an assistant professor of biogeochemistry from Montana State University, believe they have solved the mystery. (more …)
GAINESVILLE, Fla. — Floridians value water, almost as much as they value money and their health — just don’t ask them to time themselves in the shower.
An online survey of 516 Floridians found that interest in water ranked third in a list of public issues, just behind the economy and health care, but ahead of taxes and public education. Eighty-three percent of respondents considered water a highly or extremely important issue.
GAINESVILLE, Fla. – The University of Florida Water Institute will host its fourth symposium, “Sustainable Water Resources, Complex Challenges, Integrated Solutions,” Feb. 11-12 at the J. Wayne Reitz Union.
This year’s conference focuses on what organizers call “Water Supply Planning in a Non-Stationary World.” The forum is meant to bring many professional perspectives together to focus on science, technology, management, policy and public action.

GAINESVILLE, Fla. – Captive breeding of the endangered Key Largo woodrat may not be the best solution to preserve the ecologically important rodent, an animal driven to near extinction by development, a new University of Florida study shows.
Using a computer model, scientists developed a captive breeding-and-release program to see if adding captive-reared animals outweighed the loss of rats from the wild. But it did not, the study said.
Robert McCleery, UF assistant professor in wildlife ecology and conservation and co-author of the study, estimated that fewer than 500 of the woodrats remain. That’s down from U.S. Fish and Wildlife Service estimates of about 6,000 in 1984.

GAINESVILLE, Fla. — African crocodiles, long thought of as just three known species, are among the most iconic creatures on that continent. But recent University of Florida research now finds that there are at least seven distinct African crocodile species.
The UF team’s latest discovery, led by then-doctoral candidate Matthew H. Shirley, is that what had been believed to be a single species of slender-snouted crocodile, is actually two.

GAINESVILLE, Fla. — Although some scientists suggest that coral reefs are headed for certain doom, a new study by University of Florida and Caribbean researchers indicates even damaged reefs can recover.
In a 13-year study in the Cayman Islands, warm ocean temperatures led to bleaching and infectious disease that reduced live coral cover by more than 40 percent between 1999 and 2004. But seven years later, the amount of live coral on the reefs, the density of young colonies critical to the reefs’ future health, and the overall size of corals all had returned to the 1999 state, the study showed.
GAINESVILLE, Fla. – More than half of all fresh produce in the United States is wasted every year, the vast majority due to retailers and consumers throwing out fruits and vegetables gone bad after being at the store or home for too long.

GAINESVILLE, Fla. — Restaurants and supermarkets could save millions of dollars by hanging on to bug zapper bulbs instead of tossing them every year as they normally do, a new University of Florida study has found.
What’s more, the benefits could extend to the environment by keeping some of the bulbs’ mercury out of the waste stream.
GAINESVILLE, Fla. – The University of Florida has released three smart device apps of interest to those in the irrigation business, and for the time being, users can download them for free.
The first three apps to be released were designed for citrus, strawberry and urban turfgrass irrigators, said Kati Migliaccio, an associate professor in agricultural and biological engineering, based at the UF Institute of Food and Agricultural Sciences’ Tropical Research and Education Center in Homestead, Fla.
GAINESVILLE — Using boomboxes to amplify predator bird sounds in the wild, University of Florida researchers have found that smaller birds listen to vocal cues to avoid areas populated by predators.
In her study, doctoral student Fangyuan Hua set up above-ground boomboxes mounted in camouflaged boxes on half-acre plots at the Ordway-Swisher Biological Station near Melrose.
Powered by car batteries, these boomboxes were programmed for four months to broadcast predator sounds according to a schedule that simulated when and how predators would normally call.
