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.

GAINESVILLE, Fla. — Animal biodiversity suffers near conservation areas that border big farms, and the effects can spread for miles, according to a new study by University of Florida researchers and their colleagues.
Maintaining animal biodiversity is important as it can lead to greater control of agricultural pests and increased pollination around farmland as well as help maintain the health of an area’s ecosystem, said Robert McCleery, a study co-author.
The researchers studied small mammal populations across large-scale sugarcane production areas and adjacent to isolated pockets of conservation land in Swaziland, Africa. The study was published Monday in the online journal PLOS ONE and can be viewed here: http://dx.plos.org/10.1371/journal.pone.0074520.

GAINESVILLE, Fla. — Captive “wild” horses will cost U.S. taxpayers $1 billion by 2030 if federal management approaches don’t change, according to a new report by a pair of researchers who were part of a national committee that studied the issue.
A possible solution, they say: contraceptive vaccines.
The report by researchers Madan Oli of the University of Florida’s Institute of Food and Agricultural Sciences, and Robert Garrott of Montana State University, was published late last week in the journal Science. Oli is a professor in the wildlife ecology and conservation department, and Garrott is a professor in the MSU ecology department.

GAINESVILLE, Fla. — Despite a soggy summer, water supply remains a critical issue in the Sunshine State. University of Florida researchers now say that reducing plant material, or biomass, in forests could significantly increase water supplied to streams, lakes and aquifers.
Researchers with the UF Institute of Food and Agricultural Sciences made the finding by creating computer models that analyzed the effects of reduced forest biomass on regional hydrological supplies. Their results will be published in the August issue of the Journal of the American Water Resources Association.
In one 4,000-acre tract in Central Florida, the model predicted that converting a densely planted pine forest to one managed with slightly fewer trees per acre could supply an additional 400,000 to 1.6 million gallons of water per day to the regional water supply.
GAINESVILLE, Fla. — Depending on one’s perspective, goliath grouper are either a conservation success story or a protected species that no longer needs help, according to a new survey from the University of Florida.
Atlantic goliath grouper, part of the sea bass family, were overfished from the 1960s through the 1980s and their numbers thinned until 1990, when a harvest moratorium was put into place in U.S. waters. As the name suggests, the slow-moving fish can reach 800 pounds and more than 8 feet in length. They’re found off Florida’s coasts, throughout the Caribbean and off West Africa.

Marty Main, associate dean for University of Florida Extension and associate director of Florida Sea Grant, is being recognized for his educational outreach by the Ecological Society of America.
He has been awarded the Eugene P. Odum Award for Excellence in Ecology Education for the success of the Florida Master Naturalist Program.
The award will be presented in August at the 2013 Ecological Society of America meeting in Minneapolis. It recognizes ecologists for outstanding work in ecology education and their program’s ability to connect basic ecological principles to human affairs.

GAINESVILLE, Fla. — University of Florida researchers have found, for the first time, that crop models predicting yields for one of the world’s most important crops begin to disagree under climate change scenarios.
By knowing where those models break down, researchers will be better able to improve them. The computerized models predict crop yields for wheat, one of the world’s most-consumed foods.
Scientists use crop models to foresee which parts of the world may face the greatest food shortages, so that efforts to improve food production can be directed to those places.

GAINESVILLE, Fla. — There is no evidence that pollutants from the 2010 Gulf of Mexico oil spill contributed to the “unprecedented” decline in recent Apalachicola Bay oyster populations, according to a report this week by the University of Florida.
Instead, the report by UF’s Oyster Recovery Team cites drought, insufficient rainfall and increased salinity in the bay as factors contributing to the dramatic drop-off in oyster landings beginning in September 2012 and continuing through the year, said Karl Havens, task force leader and director of Florida Sea Grant.
“There was a whole chain of circumstances that led to this situation, some of which are beyond human control,” Havens said. “Our report makes recommendations for many things that can be done to help the oyster population through management and restoration.”
Havens and other recovery team members discussed the report and findings with a crowd of about 60 residents and seafood workers Wednesday at the Apalachicola Community Center.
