GAINESVILLE, Fla. — Among his legacies, Ed Gilman wants to make sure trees don’t snap in Florida’s tropical storm-force winds.
When Gilman retires this month from the University of Florida Institute of Food and Agricultural Sciences, he can point at several crowning achievements in his career.
Now, at age 62, Gilman will spend more time with family, of course, and do more woodworking, “working with dead trees instead of live trees,” he deadpanned.
GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers will introduce genetic biotechnology as a potential means to preserve forests at a national conference next week in Washington, D.C.
Jiri Hulcr, an assistant professor in the UF/IFAS School of Forest Resources and Conservation, and one of his doctoral students, Caroline Storer, will host the symposium at the North American Forest Insect Work Conference May 31 to June 3.
Hulcr sees this conference as an opportunity for the UF/IFAS forest entomology team to disseminate innovative solutions to maintain tree health.
“Exploring the use of biotechnology in tree health protection is important to us, because we are increasingly running out of other options,” Hulcr said.
Additionally, he said: “Trees and forests provide jobs and benefits for everyone. Yet, around city neighborhoods and rural forests, anyone can witness the diminishing health of trees. The culprit is exotic pests and diseases. Forget pollution or drought: It is destructive tree diseases and pests — imported by overseas travelers or business people — that are nearly eliminating some tree species from our forests and orchards.”

GAINESVILLE, Fla. — Heat from city sidewalks, streets, and parking lots, along with insect pests, can damage trees planted in urban landscapes. Thus, it is critical to plant trees in the right places so they will do well in harsh urban environments, a University of Florida Institute of Food and Agricultural Sciences researcher says.
More than half the world’s people and 80 percent of the U.S. population live in urban areas. Trees benefit these residents by filtering the air, reducing temperatures and beautifying landscapes. According to a new study led by Adam Dale, a UF/IFAS assistant professor of entomology, these benefits are reduced when trees are planted in unsuitable urban landscapes. However, guidelines can be developed to lead urban tree- planting decisions in a more sustainable direction.
Dale spearheaded the study while at North Carolina State University in Raleigh, North Carolina. Previous research by Dale and his colleagues found that impervious surfaces raise temperatures, which increase pest abundance and tree stress, ultimately reducing tree health. He and his team examined the so-called “gloomy scale insect,” which feeds on tree sap and appears as small bumps on the bark of trees.
GAINESVILLE, Fla.— Arbor Day is approaching and Seffner, Florida, residents are geared up to celebrate with an Arbor Day mail art contest presented by the University of Florida Institute of Food and Agricultural Sciences Extension Hillsborough County.
National Arbor Day, April 29, is a time for the global community to come together and celebrate the importance of trees by planting new ones and taking care of the trees already in existence. Trees play an essential part in the ecosystem because they provide clean air and water as well as slow climate change. They also prevent species loss and alleviate poverty and hunger.
This year’s Arbor Day theme for the mail art contest is titled “I appreciate trees because…” Contestants will submit their art, along with their name, age and number, to the Extension office for a chance to be one of three winners. The categories are divided by three age groups: child, youth and adult. Three winners will receive a tree planting kit worth $100, and their art work will be displayed in the lobby of the UF/IFAS Extension Hillsborough County office.
The winners from each age group will be chosen before Arbor Day, and they must be present at Kerby’s Nursery on April 29 at 6 p.m. to receive their prizes.

GAINESVILLE, Fla. — When you think of wildfires, you may not think of wetlands. But the seldom-seen blazes may help some endangered species, according to a newly published study by a former UF/IFAS researcher.
Severe wetland fires — so rare they occur only a few times per century – also can change vegetation and patterns of water movement, said Adam Watts, who led the study as a post-doctoral researcher in the UF/IFAS School of Forest Resources and Conservation.
During a smoldering fire, wetlands can become deeper if the fires burn muck or peat soils.
“In some cases, this could help improve habitat for endangered species, such as wood storks,” said Watts, now a research assistant professor at the Desert Research Institute in Reno, Nevada. But wetland fires can also kill many trees and shrubs, causing changes to the vegetation that returns.
GAINESVILLE, Fla. — The next time you take a stroll through the woods here in Gainesville, you might want to look down – you could be walking on an undiscovered species of fungus.
University of Florida post-doctoral researcher Keisuke Obase did just that recently, finding the newly named Cladophialophora floridana, in honor of the state, at Split Rock Conservation Area and C. tortuosa at Bivens Arm Nature Park. The discoveries have been accepted for publication in the journal Mycoscience. (more …)
GAINESVILLE, Fla. — Two former doctoral students from the University of Florida Institute of Food and Agricultural Sciences are running a genetics startup company in Gainesville and recently were recognized by Gov. Rick Scott as “Young Entrepreneurs.”
Marcio Resende said he came up with the idea for RAPiD Genomics while in Brazil due to a demand from a forestry company that needed someone to do some genotyping for them. Several factors, including costs, kept him from pursuing the notion.
But when he came to the United States to pursue his doctorate, he started talking to Leandro Gomide Neves, a fellow doctoral student, and Matias Kirst, a professor of forest genomics at UF/IFAS. They decided to open RAPiD Genomics. At the same time, they teamed up with some colleagues to invent a genotyping method, which gave them extra motivation to pursue the idea of opening a business.
GAINESVILLE, Fla. — The next time a storm tears up your yard, let an expert assess the damage to any trees. A study from the University of Florida Institute of Food and Agricultural Sciences shows that homeowners perceive the risk of a damaged tree differently than trained professionals.
The survey of tree experts and homeowners in the Tampa Bay area assessed the perceptions of both groups when it came to assessing tree damage, said Andrew Koeser, an assistant professor in environmental horticulture and study author.
“While there are a number of factors tied to tree risk, most respondents were fixated on tree defects,” Koeser said. “Only experienced professionals considered other pertinent factors—namely whether the tree was actually a threat to a person, vehicle or house.”
GAINESVILLE, Fla. — A UF/IFAS scientist, who has helped design a tree risk-management app and is co-writing tree identification books, has been named as a co-recipient of the International Society of Arboriculture’s Early Career Scientist Award.
The award is given to professionals showing exceptional promise in arboriculture research.
Andrew Koeser, an assistant professor in environment horticulture at the UF/IFAS Gulf Coast Research and Education Center in Baum, is also a faculty member at the UF/IFAS Center for Landscape Conservation and Ecology.
One of Koeser’s projects is a mobile app for risk-assessment data collection and mapping. He is also co-writing a series of tree identification books unique to the different regions of Florida.
Koeser hopes his research enhances efforts to improve risk-assessment and storm response processes. The app project is designed to give cities an easy and efficient means of taking inventory and assessing the safety of their trees. Should a severe storm hit, the data collected will help managers more quickly estimate debris levels for cleanup.
“My research in tree risk assessment carries on the goal of enhancing current efforts being made to improve assessment processes,” said Koeser, a faculty member with the University of Florida Institute of Food and Agricultural Sciences. “I think the app project has the potential to gather user data needed in order to make reasonable assessments of potential tree failure.”
GAINESVILLE, Fla. — After three decades of outstanding forestry research, A UF/IFAS professor will receive one of the top global awards in his field.
Eric J. Jokela, a professor of silviculture – managing and producing better forests — and forest nutrition will receive the Barrington Moore Memorial Award in Biological Science by the Society of American Foresters (SAF). Since 1955, this annual award recognizes “distinguished individual research in any branch of the biological sciences that has resulted in substantial advances in forestry,” according to a release from the society.
“Being the recipient of this award is indeed very humbling as I reflect back on the previous awardees who have made lasting contributions to the field of forest science,” Jokela said. “I find it especially gratifying to know that results from our long-term, cooperative research efforts have found strong applications and also contributed to the advancement of sustainable forest management systems used in the South and elsewhere.”
