Tetraploid Induction and Establishment of Breeding Stocks for All-Triploid Seed Production

Raw oysters on ice. Oyster, shellfish, seafood, food safety. 2009 Annual Research Report photo by Tyler Jones.

Triploid-tetraploid breeding technology has been applied to commercial oyster aquaculture worldwide. Triploid oysters are becoming the preferred aquaculture product because of their fast growth, better meat quality, and year-round harvest. Tetraploids are essential for triploid oyster aquaculture because commercial production of all-triploid seed depends on the availability of tetraploids for reproductive materials. This 8-page fact sheet written by Huiping Yang, Ximing Guo, and John Scarpa and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences, conveys basic knowledge about tetraploid induction and breeding to commercial shellfish culturists and the general public.

Biology and Management of Pusley (Richardia L.) in Tomato, Pepper, Cucurbit, and Strawberry Production

Four species of pusley (Richardia L.) are widespread and common weeds in Florida vegetable and strawberry production. We refer to the native plant Richardia scabra L. as Florida pusley. This discrimination is necessary because these species are often referred to collectively as Florida pusley due to overlapping distributions, similar growth habits and leaf morphologies, and difficulty identifying without the presence of fruit. This new 6-page publication of the UF/IFAS Horticultural Sciences Department describes the different pusley species and provides management options for strawberry, pepper, cucurbits, and tomato. Written by Shaun M. Sharpe, Nathan S. Boyd, Chris Marble, and Shawn Steed.

This 5-page fact sheet written by Mathieu Basille and Kathryn Stofer and published by the UF/IFAS Wildlife Ecology and Conservation Department is the first of a series designed to help Extension faculty and others interested in hosting citizen-science events known as BioBlitzes. Together, these documents will assist organizers in launching events in their regions, recruiting participants, and sustaining the program over time. This document will focus on the background and purpose of BioBlitzes to help these hosts understand and share with potential participants and other stakeholders the importance and value of the events. Other documents will focus on the details of organizing the events and, for participants, why and how they can get involved.

Florida water-resource professionals deciding whether to implement a costly water protection program or to invest in better tap water treatment technology may wonder: Are such investments justified? What are the benefits of the program or investment decision? Just how highly do Floridians value their water? This 5-page fact sheet written by Tatiana Borisova, Syed Irfan Ali Shah, Tara Wade, Xiang Bi, and Kelly Grogan and published by the UF/IFAS Food and Resource Economics Department reviews studies that help assess the value Floridians assign to maintaining or improving the quality of the water supply.

The hot and humid weather in Florida affects dairy cattle performance throughout the year, and producers who hope to achieve optimum production from their dairy cows must provide them with relief from heat and humidity. This 4-page fact sheet written by I. M. Toledo, G. E. Dahl, R. A. Bucklin, and D. K. Beeke and published by the UF/IFAS Department of Agricultural and Biological Engineering describes several cooling strategies to alleviate heat stress in dairy cattle.

Lethal Bronzing Disease (LBD)

Figure 5. Discoloration of the lowest (older) leaves is an early symptom of TPPD in cabbage palm.

Lethal bronzing disease (LBD), formerly Texas Phoenix Palm Decline (TPPD), is a lethal phytoplasma infection of various palm species in the state of Florida. It was first detected in Florida in 2006 and has since spread to 31 different counties and been isolated from 16 different species of palm. This three-page fact sheet describes the pathogen and hosts of LBD, its symptoms, how to diagnose it, and disease management practices. Written by Brian W. Bahder and Ericka Helmick and published by the UF/IFAS Plant Pathology Department, this article is a revision of an earlier fact sheet by Nigel A. Harrison and Monica L. Elliott.

School-Based 4-H Programming: Incorporating Family Engagement into Your Program

family sillouhetted against horizon

Family engagement in 4-H programs allows family members, youth, and the community to become more aware, cohesive, and invested in youth development. This 4-page fact sheet, written by Vanessa Spero-Swingle and published by the UF/IFAS Florida 4-H Youth Development Program, discusses how to incorporate family engagement into your 4-H school programming. For the purposes of Florida 4-H, a school-based program can be defined as school enrichment (offered to groups of youth, taught by Extension staff or trained volunteers, and designed to support the school curriculum), an in-school club following a more traditional club approach during school hours, or an after-school club operating directly after school hours.

All youth, regardless of age, are at risk for engaging in negative behaviors that can get them into trouble during the afterschool hours when parents and other family members are at work. Middle and high school-age youth are at an age where they can most benefit from increasing opportunities to participate in programs with a positive adult role model, gain necessary life skills, and increase their knowledge of accessible opportunities. Middle and high school programs have the potential to support graduation rates and increase post-secondary school success. This 4-page publication of the UF/IFAS Florida 4-H Youth Development Program provides strategies for success in developing these programs in your community. Written by Vanessa Spero-Swingle.

Partnerships open a world of possibilities. Partnerships provide an opportunity for multiple organizations to address community challenges while benefiting at the same time through shared resources, funding, personnel, and expertise. Desiring to partner with a school-based site is beneficial, but not always easy to implement. Being professional in your collaboration, prepared in your assessment, and intentional about your needs are ways to increase the likelihood of a successful partnership. This 4-page publication of the UF/IFAS Florida 4-H Youth Development program offers tips and strategies to build healthy, mutually beneficial partnerships in your program.

Using Interest Approaches in Instructional Design and Delivery

Students in an auditorium classroom.

Most educators know that it can be challenging to get students motivated to learn at the start of a lesson. The importance of student motivation, academic desire, and engagement is well noted as these factors have been directly linked to students’ academic achievement. An interest approach uses a brief activity to stimulate students’ situational interest toward a topic. Although situational interest is typically held by the learner for a short duration, establishing situational interest at the start of the lesson maximizes students’ engagement, motivation, and attentiveness toward the lesson’s topic and student learning objectives. This new 4-page publication of the UF/IFAS Department of Agricultural Education and Communication describes components of interest approaches and techniques for integrating them into a lesson, and provides real-world examples. Written by Brianna N. Shanholtzer, Andrew C. Thoron, J. C. Bunch, and Blake C. Colclasure.

Identifying and Meeting the Needs of Extension?s Target Audiences

Upfront discussions about expectations could potentially offset or defuse future problems.

This new 4-page article provides an overview of the concept of target audiences as relating to Extension education and briefly presents concepts of audience analysis and educational content selection. In contrast to the general population, a target audience is comprised of people who can take some explicit action to help solve an identified problem addressed by an Extension program. Sometimes they are also those most affected by that problem. An understanding of the concept of target audiences paired with intentional selection of appropriate educational activities and content can support an impactful Extension program. Written by Laura A. Warner, Glenn D. Israel, and John M. Diaz, this article is a publication of the UF/IFAS Department of Agricultural Education and Communication.
