GAINESVILLE, Fla. — Floridians would likely support a 1 percent sales tax bump to prevent and eradicate disruptive invasive species, a new University of Florida Institute of Food and Agricultural Sciences public opinion survey shows.

The survey also shows that residents say they’re not as up to speed on endangered and invasive species as they would like to be.

Study: Endangered elephants’ outlook bleak without more room to roam

Topic(s): Conservation, Research

GAINESVILLE, Fla. — Intelligent and beautiful, the Asian elephant is running out of time unless humans step aside and give it some room.

Shrinking habitat and conflicts with humans could hurt the endangered elephant’s numbers and throw the species’ viability into question.

In a new study published this month in the journal Biological Conservation, University of Florida researchers looked at what must happen for the species to avoid extinction.

UF/IFAS study shows flavor trumps health for blueberry buying

GAINESVILLE, Fla. — Taste trumps health benefits for blueberry buyers, sending a strong message that fruit consumers value flavor most, new University of Florida research shows.

About 61 percent of blueberry consumers buy the fruit for its flavor, while 39 percent do so for psychological reasons, according to two national online surveys. By “psychological,” researchers mean those consumers may buy blueberries because they believe the fruit, which contains antioxidants, provides health benefits.

UF horticultural sciences assistant professor Jim Olmstead will use the data as he breeds new types of blueberries. Olmstead uses traditional breeding methods to create blueberry cultivars that have traits consumers want.

“What we’re trying to determine is: What is the consumer’s perception of the ideal blueberry? What should it look, taste and feel like?” said Olmstead, a faculty member with UF’s Institute of Food and Agricultural Sciences.

UF/IFAS study: Strawberry monitoring system could add $1.7 million over 10 years to some farms

GAINESVILLE, Fla. – A University of Florida-developed web tool can bring growers $1.7 million more in net profits over 10 years than a calendar-based fungicide system because it guides growers to spray their crop at optimal times, a new UF study shows.

The Strawberry Advisory System, devised by an Institute of Food and Agricultural Sciences researcher, takes data such as temperature and leaf wetness and tells growers when to spray fungicide to ward off diseases. Growers can use the system by logging onto www.agroclimate.org/tools/strawberry or use the website to sign up for email or text alerts.

Before the system was developed, strawberry farmers traditionally sprayed weekly during the November-to-March growing season. Spraying more often than is needed wastes money and can lead to fungicide resistance, said Natalia Peres, associate professor in plant pathology, who led the system’s development.

Not all strawberry growers use the system, but this research might persuade them to do so, said Tatiana Borisova, an assistant professor in UF/IFAS food and resource economics department.

Predicting disease and improving crops through genetics

GAINESVILLE, Fla. – Can scientists accurately predict when an individual will develop a disease? What if we could predict how to increase drought resistance in plants? Or offer patients personalized medicine?

Researchers are looking for answers to these questions and more using a plant or animal’s obvious traits, called phenotype prediction, a field that will be discussed in a free workshop presented by the University of Florida Forest Genomics Lab, the Forage Breeding and Genomics Lab and Genetics Institute Aug. 11 from 8 a.m. to 1:30 p.m.

Held in the UF Cancer & Genetics Research Complex auditorium, the event can be streamed live online. Faculty, students, researchers and breeders working with plant, animal or human genomic data locally or worldwide are invited to participate. In its first year, the workshop attracted participants from 64 countries.
