GAINESVILLE, Fla. — Two faculty members in the UF/IFAS Department of Agricultural and Biological Engineering have won prestigious global awards for outstanding contributions to their field.

One has also been elected to an advisory panel to the government of Spain.

Professor Rafael Muñoz-Carpena, has won the 2015 Hancor Soil and Water Engineering Award for “accomplishments in hydrological and integrated environmental modeling and education of next-generation soil and water scientists and engineers.”

Muñoz-Carpena, who specializes in hydrology and water quality, remembers when, as a doctoral student at North Carolina State University, his mentor, Wayne Skaggs, won the award. Skaggs later became a member of the National Academy of Sciences. Skaggs “is one of the fathers of modern agricultural drainage,” says Muñoz-Carpena.

The Hancor award means every bit as much to Muñoz-Carpena now.

“It has additional meaning to me,” he said, because his former mentor won the award. “It’s recognition of your work among peers. The fact that I got it surprises me.”

UF/IFAS study: Non-native grass invasion, prescribed fires, deadly ecological combination

INVASIVE BURNS 051115 from Flory

GAINESVILLE, Fla. — Invasive stiltgrass is bad enough by itself, crowding out native plant and insect species in about 25 eastern U.S. states, including Florida. It can also inhibit tree seedling survival and growth, and it can change the availability of nitrogen in the soil.

In general, invasions of non-native plant species can reduce biodiversity and alter ecosystems. In 2013, 1,585 prescribed fires were used to burn about 290,000 acres in eight eastern U.S. states. Scientists have used prescribed fires to effectively control some invasive plants, but new evidence suggests fires may promote stiltgrass invasions.

If land managers perform prescribed fires — normally used to manage ecosystems and prevent wildfires – in stiltgrass-invaded areas, native trees can be killed by the more intense fires caused by burning stiltgrass, said Luke Flory, an assistant professor of ecology at the University of Florida Institute of Food and Agricultural Sciences.

GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences faculty have developed a new app for avocado growers that provides an irrigation schedule so users save an estimated 20 to 50 percent on the water they apply to their orchards.

“Weather changes daily, and the app takes into account these changes in the irrigation schedule it provides,” said Kati Migliaccio, an associate professor in agricultural and biological engineering at UF’s Tropical Research and Education Center in Homestead, Florida.

Fishermen, communities need more than healthy fish stocks

The Alaska salmon fishery is touted as one of the best in the world. When measured with an ecological yardstick, it is – fish stocks are healthy and the fishery is certified by the Marine Stewardship Council as consistently meeting rigorous biological standards. Fish are individually counted as they swim upstream to ensure there are enough to breed.

But Alaska salmon falls behind some of the world’s fisheries in how it benefits local fishermen, processing workers and nearby rural communities, according to a new assessment that ranks the vitality of a fishery by looking at its economic and community benefits as well as its ecological health.

“We wanted to develop a new set of metrics to determine how well fisheries management systems work and to test what factors are most effective in improving them,” said James Anderson, professor of Food and Resource Economics and director of the new Institute for Sustainable Food Systems at the University of Florida Institute of Food and Agricultural Sciences. Anderson is a lead author of a paper published May 6 in the journal PLOS ONE, describing the new methodology.

 “These new Fishery Performance Indicators (FPIs) are designed to help us evaluate a fishery system’s performance toward achieving economic, community and ecological sustainability – the ‘triple bottom line,'” he said.

GAINESVILLE, Fla. — As Florida Sea Grant’s new Gulf oil spill research Extension specialist, Monica Wilson translates oil spill science to Gulf Coast residents and stakeholders.

Her audiences include commercial, recreational and for-hire fishermen, natural resource managers, elected officials, emergency responders and managers, tourism specialists, port and harbor employees and more.

Wilson works with three other specialists, one from each of the Sea Grant programs in the Gulf – Mississippi-Alabama, Louisiana and Texas — to create a new science education program that disseminates key oil spill research results to industry and community audiences. They hope to disseminate bulletins soon about dispersants as well as fisheries.

As Wilson works with Sea Grant programs in nearby Gulf states, she and other specialists bring different expertise to foster a more comprehensive understanding of oil spill science.

GAINESVILLE, Fla. — A University of Florida scientist has developed a fertilizer for palm trees that should keep them healthy and reduce water pollution.

Environmental horticulture Professor Tim Broschat found that applying a palm fertilizer with no nitrogen or phosphorus could prevent the harmful effects of lawnfertilizers on palms.

“We also found that most palms do not need any phosphorus in their fertilizer to be healthy, and by not applying this element, we can eliminate one possible source of water pollution in Florida,” said Broschat, a faculty member at UF’s Fort Lauderdale Research and Education Center.

GAINESVILLE, Fla. — When the University of Florida’s School of Forest Resources and Conservation (SFRC) holds its annual Spring Celebration, there’s plenty of focus on the School’s storied past, but the event also salutes current students, their achievements and future aspirations, said Tim White, SFRC director and a professor with the School, part of UF’s Institute of Food and Agricultural Sciences.

The two-day event, scheduled for April 10-11, is part social gathering and part scientific symposium, welcoming all SFRC personnel, students and alumni, supporters and friends, he said. All three of SFRC’s academic divisions take part in the Celebration – Forest Resources and Conservation; Fisheries and Aquatic Sciences, and Geomatics, which includes surveying, map making and other disciplines involving geographic information.

“This is our one opportunity each year to bring together everyone connected with the School,” White said. “Spring Celebration is supposed to be inclusive, so we try to offer something for everybody.”

Events this year include a barbecue, 5K run, trap and skeet shooting competition, displays and demonstrations, and an awards ceremony for students and alumni, he said. Much of the activity will take place at the school’s new Austin Cary Learning Center, dedicated in April 2014.

UF/IFAS study: Forest managers hindered in efforts to use prescribed burns to control costly wildfires

See cutline below

GAINESVILLE, Fla. — Forest managers would prefer to use prescribed burns every few years to help prevent costly wildfires and rebuild unhealthy ecosystems, but hurdles like staffing, budget, liability and new development hinder them, a new University of Florida study shows.

Fighting wildfires is costly. The U.S. government now spends about $2 billion a year just to stop them, according to the National Interagency Fire Center. That’s up from $239 million in 1985.

Leda Kobziar, an associate professor of fire science and forest conservation in UF’s School of Forest Resources and Conservation, led a web-based survey of 523 public and private land managers across Region 8 of the U.S. Forest Service, which consists of 13 Southern states, including Florida. She and her colleagues wanted to see whether front-line experts think prescribed burns prevent wildfires and maintain vegetation and healthy ecosystems. And if they do, what are the circumstances under which such burns work best.

As it turns out, prescribed burns should be done every few years to prevent wildfires or reduce their severity, depending on weather and the type of ecosystem land managers are trying to protect, according to the survey.

GAINESVILLE, Fla. – Global experts, including three from the University of Florida Institute of Food and Agricultural Sciences, will share knowledge at an international symposium focused on the economics of urban tree management, March 18-19, in Tampa, Florida.

The meeting brings together experts from around the world and innovative professionals working with some of America’s largest and longest-standing urban forestry programs: New York and Milwaukee.

Those attending the conference will explore the value of trees as part of urban green infrastructure, try to quantify the costs associated with poor urban forest management practices and examine the potential benefits that can be reaped from proper planning and maintenance.

Once these costs and benefits have been evaluated, urban foresters, utility vegetation managers and elected officials can make effective management decisions, according to the program’s website, http://www.isa-arbor.com/events/eventsCalendar/index.aspx?ID=2077.
