What Is the ENSO Climatology Tool?

Storm rising over a farm.On a global scale, periodic anomalies in sea surface temperatures coupled with shifts in atmospheric pressure and winds, such as those associated with the El Niño Southern Oscillation (ENSO), can have profound impacts on weather conditions. ENSO affects atmospheric circulation patterns well into the midlatitudes and is the leading driver of seasonal climate variability in the United States. Tremendous advances have been made in predicting the occurrence of ENSO events with confidence three to six months in advance. This 5-page fact sheet discusses the ENSO climatology tool as well as possible challenges. Written by Caroline Staub, Clyde Fraisse, Eduardo Gelcer, and Daniel Dourte, and published by the UF Department of Agricultural and Biological Engineering, March 2017.

Hand held electronic diabetes monitoring devices. Metabolic diseases, blood sugar. Image used in the 2012 Annual Research Report.

When people have type 1 or type 2 diabetes and take multiple daily insulin injections, their blood glucose levels can rise drastically due to a cold or another minor illness. This can result in serious health problems. The best way for people with diabetes to prevent a minor illness from becoming a major illness is to have a personalized sick day plan designed with their health care provider before they become ill. This 4-page fact sheet is a major revision that discusses ways in which illness affects diabetes control, development of a sick day plan, times to call your health care provider, checking blood glucose and urine ketones, medicines, and diet. Written by Nancy J. Gal and Linda B. Bobroff, and published by the UF Department of Family, Youth and Community Sciences, revised June 2017.

Citrus Under Protective Screen (CUPS) Production Systems

Citrus can be grown under protective screen structures for fresh fruit production in order to completely exclude the Asian citrus psyllid and therefore huanglongbing disease (HLB, citrus greening). The benefits of eliminating HLB are immediate and include rapid, normal tree growth, higher yields of quality fruit, negligible fruit drop, and uncomplicated fertilizer and irrigation requirements. Because CUPS is a relatively new citrus production system with new challenges, current guidelines are preliminary and undergoing constant refinement through research. This summary of concepts, progress, and tentative recommendations from the first three years of CUPS research in Florida written by A. W. Schumann, A. Singerman, A. L. Wright, and R. S. Ferrarezi and published by the Horticultural Sciences Department was condensed from a comprehensive CUPS Quick Start Guide that will be published and updated on the UF/IFAS EDIS website.

South Florida Tropicals: Carambola

The names carambola and mamey sapote may not be household words yet, but researchers at the University of Florida's Institute of Food and Agricultural Sciences say these tropical "designer" fruits may bring sweet success for South Florida growers who lost hundreds of acres of groves and farmland in Hurricane Andrew. Tropical fruit crops specialist Jonathan Crane, shown tasting a carambola or "star fruit" at UF/IFAS' Tropical Research and Education Center in Homestead, is working with farmers to establish the new crops in the area. UF/IFAS economists say the fruits, already popular in Asian and Hispanic cultures, could create valuable new markets for South Florida.The carambola or star fruit is native to Southeast Asia. It was introduced to Florida about 100 years ago. This 4-page fact sheet is a major revision that discusses availability, selection, uses, nutritive value, and food safety during preparation of carambola. This document also includes several recipes. Written by Amy Simonne and Linda B. Bobroff, and published by the UF Department of Family, Youth and Community Sciences, revised April 2017.

Healthy Eating: Understanding the Nutrition Facts Label

University of Florida Associate Professor Linda Bobroff shows a student how to read a nutrition label on a frozen dinner, Tuesday (10/14), as part of Smart Food Shopping for Teens, a program developed at UF's Institute of Food and Agricultural Sciences. The program also teaches teens about enviroshopping, the practice of choosing products that are not overpackaged and that can be recycled. The program is aimed at teaching teens good shopping and eating habits before they form bad ones.The U.S. Food and Drug Administration (FDA) requires that most food packages have the Nutrition Facts label. This label contains information about nutrients in the food to help people make healthier food choices. Older adults can use the label to choose foods that provide required daily nutrients or fit with a diet plan to manage a disease or health condition. This 4-page fact sheet is a major revision that discusses the Nutrition Facts label, checking calories, limiting certain nutrients, % Daily Values, and consuming enough fiber, vitamin D, potassium, calcium, and iron. Written by Linda B. Bobroff and Karla P. Shelnutt, and published by the UF Department of Family, Youth and Community Sciences, revised May 2017.

Oil Spill Science: Sea Grant Programs of the Gulf of Mexico: Persistence, Fate, and Effectiveness of Dispersants used During the Deepwater Horizon Oil Spill

The large-scale applications of dispersants used at the surface and wellhead during the Deepwater Horizon oil spill raised many questions about dispersants and highlighted the importance of understanding their effects on the marine environment. Written by Monica Wilson, Larissa Graham, Christine Hale, Emily Maung-Douglass, Stephen Sempier, and LaDon Swann and published by the Florida Sea Grant College Program, the fact sheet was selected for publication on EDIS by Monica Wilson.
