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. – A computer model developed, in part, by University of Florida researchers can help coastal managers better understand the long-term effects of major storms, sea-level rise and beach restoration activities and possibly save millions of dollars.
Researchers used erosion data following tropical storms and hurricanes that hit Santa Rosa Island, off Florida’s Panhandle, and sea-level rise projections to predict beach habitat changes over the next 90 years. But they say their model can be used to inform nourishment decisions at any beach.
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.— The National Academy of Inventors named as a Fellow this month Lonnie O. Ingram, a distinguished professor in the University of Florida’s microbiology and cell science department.
Academic inventors and innovators elected to the rank of NAI Fellow were nominated by their peers and it is considered a high professional distinction. NAI members chose Ingram because he has “demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on quality of life, economic development, and the welfare of society.”
“It’s an unexpected honor and I’m happy to be included among this group,” Ingram said Thursday. (more …)

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. — A University of Florida researcher is exploring whether the latest plant, animal or human health threats will come from the sky.
Using the first ever high-altitude sampling device designed to collect microorganisms from the upper atmosphere, Andrew Schuerger, an aerobiologist with UF’s Institute of Food and Agricultural Sciences, will examine the massive dust clouds that roll into Florida from Africa each year.
The maiden flight of the device, known as Dust at Altitude Recovery Technology or DART, was flown on an F-104 Starfighter jet Tuesday at the Kennedy Space Center in Cape Canaveral.
GAINESVILLE, Fla. – University of Florida researchers will use $1.45 million in federal grants to develop trait-prediction models and accelerate the growth of loblolly pine trees to produce more bioenergy.
In his grant application, UF associate professor Matias Kirst, the principal investigator for the study, said Southern pines can be used as renewable biomass for bioenergy and renewable chemicals. However, for pines to meet their potential as a bioenergy crop, researchers must develop more productive cultivars that can be efficiently converted into liquid fuels, said Kirst, who teaches in the School of Forest Resources and Conservation, part of UF’s Institute of Food and Agricultural Sciences.
