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.

GAINESVILLE, Fla. — People who live in the southeastern United States should begin to prepare for more drastically changing weather conditions – everything from heat waves to poorer air quality – caused by climate change, according to a new book, edited by a University of Florida researcher.
The book, which UF’s Keith Ingram helped write, is titled “Climate Change of the Southeast United States: Variability, Change, Impacts and Vulnerability.” Ingram was the book’s lead editor.

GAINESVILLE – Renowned scientist Michael Mann will give the keynote address at the 2013 E.T. York Lecture Series Nov.19 at the Emerson Alumni Hall at the University of Florida.
Mann, a distinguished service professor of meteorology at Penn State University, will address the “Hockey Stick and the Climate Wars: Dispatches from the Front Lines.”
In his recent book “The Hockey Stick and the Climate Wars,” Mann discusses his experiences in the center of the climate change debate resulting from a graph he and his co-authors published 15 years ago, demonstrating the unprecedented nature of modern climate change. The line of the graph charted global temperatures over the last 1,000 years, starting to spike upward in about 1850, resulting in a graph that resembled a hockey stick. (more …)
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.
Jeffrey Brecht is the leader of one of two research groups at UF awarded grant money by the National Strawberry Sustainability Initiative.

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. — Many scientists see great promise in algae as a new source of oil — a sustainable, environmentally sound way to break the world’s fossil fuel dependence.
Algal lipids from microalgae are one of the best sources for biofuels – algae grow quickly, tolerate extreme weather conditions, and do not pose the same issues as biofuel crops that are grown both for fuel and food.
Many research teams in academia and private industry are struggling, however, with one vexing problem with algae as a fuel source: The conditions that promote algal growth aren’t the same as the conditions that allow the algae to create the maximum amount of oil.
