The UF/IFAS EDIS website is a comprehensive, single-source repository of all current UF/IFAS numbered peer-reviewed publications.

Sources and Transformations of Nitrogen in Urban Landscapes -- With 80% of Florida's residents living within 10 miles of the coast, Florida's aquatic resources are directly affected by urbanization. The intent of this new 6-page publication of the UF/IFAS Department of Soil and Water Sciences is to describe the urban nitrogen cycle for a nontechnical audience. Ultimately, this document is intended for individuals working in urban environments and concerned about nutrient pollution and water quality issues, but do not have a technical background and want to improve their understanding of nitrogen cycling. Written by Alexander J. Reisinger, Mary G. Lusk, and Ashley R. Smyth.

How Effective and Humane Is Trap-Neuter-Release (TNR) for Feral Cats? As the number of feral cats continues to increase, land managers, public health officials, and private citizens are voicing concerns about how to address the nuisance and public health impacts, as well as animal welfare concerns, that feral cats create. Trap-neuter-release programs aimed at reducing feral cat populations without euthanasia are gaining popularity in the United States. But do they work? Authors Mark Hostetler*, Samantha M. Wisely, Steve Johnson, Elizabeth F. Pienaar, and Martin Main discuss the pros and cons of trap-neuter-release programs in this 8-page fact sheet published by the UF/IFAS Department of Wildlife Ecology and Conservation.

Ocean Acidification: Calcifying Marine Organisms -- Rising atmospheric carbon dioxide concentration leads to ocean acidification and threatens coastal and marine ecosystems and organisms. This 4-page fact sheet written by Joseph Henry, Joshua Patterson, and Lisa Krimsky and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences explores the impacts of ocean acidification on calcification, the process corals, bivalves, echinoderms, and planktonic organisms use to build their shells and skeletons. Understanding how ocean acidification affects calcification is important for scientists seeking to determine the real-world implications and impacts of ocean acidification on some of the most important species in the marine environment.

Ocean Acidification: Fish Physiology and Behavior -- Increased atmospheric carbon dioxide has led to increased levels of dissolved carbon dioxide in the oceans and acidified ocean water, which could have direct effects on the physiology and behavior of fishes. This 5-page fact sheet written by Joshua Patterson, Lisa Krimsky, and Joseph Henry and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences will summarize the current state of our understanding on the topic, with special emphasis on Florida fishes. It will also address current challenges in understanding the real-world effects of a complex global process using data largely collected on isolated fish in laboratory experiments.

Economic Value of Florida Water Resources: Contributions of Tourism and Recreation to the Economy -- Recreation is only one of the benefits people receive from water resources. Water is essential for fisheries and aquaculture, for drinking and bathing, for sanitation, and for spiritual and symbolic purposes, among myriad other uses described in the Economic Value of Florida Water Resources series. This 6-page fact sheet written by Tatiana Borisova*, Kurt Oehlbeck, Xiang Bi, Tara Wade, Alan Hodges, Kelly Grogan, and Fe Hei and published by the UF/IFAS is the second part of the series. It discusses the contribution of water-based tourism to the economy in various Florida regions, summarizing a number of economic studies and focusing on freshwater-based recreation, such as canoeing, freshwater angling, wildlife watching, lake- or river-shore hiking, spring diving, and more. Readers can pick and choose the studies most relevant to their geographic area or their area of interest.

Quantum GIS (QGIS): An Introduction to a Free Alternative to More Costly GIS Platforms -- Geographic information system (GIS) software packages can be prohibitively expensive, causing many to shy away from mapping and spatial analysis. This 7-page fact sheet written by Jeffry M. Flenniken, Steven Stuglik, and Basil V. Iannone III and published by the UF/IFAS School of Forest Resources and Conservation introduces the reader to a free GIS software package called Quantum GIS (QGIS), walking the reader through simple GIS processes that can be used to visualize spatial patterns of importance to a variety of fields, including natural resources, agriculture, and urban planning. Learn how to create a land-cover map for a county of interest and create heatmaps that illustrate the density of a given attribute (Florida Springs for this example). This publication will benefit those interested in incorporating GIS into their work but who are unable to afford expensive proprietary GIS software packages, as well as anyone interested in learning a new GIS software package.

Basic Tips for Designing Efficient Irrigation Systems -- As freshwater resources become increasingly scarce and droughts become more frequent, there is a need for efficient use of water resources. Designing efficient irrigation systems and equipment will not only save money but also conserve water. This 10-page fact sheet discusses factors to consider when designing irrigation systems. Written by Haimanote K. Bayabil, Kati W. Migliaccio, Michael Dukes, and Laura Vasquez, and published by the UF/IFAS Department of Agricultural and Biological Engineering, February 2020.

Effectiveness of Retail Promotions in the Green Industry by Age Group: A Case Study -- Do people of different ages shop differently for their garden plants? This 6-page fact sheet published by the UF/IFAS Food and Resource Economics Department shares results from a study investigating differences between younger and older consumers and their visual attention to in-store signage and plant tag information. Authors Hayk Khachatryan and Alicia Rihn provide a deeper understanding of how end consumers use point-of-sale information to determine their purchases in the retail center. Green industry growers, marketing intermediaries, and retailers will find the information useful as they design in-store marketing materials.

How to Properly Dispose of Unwanted Medications -- Properly disposing of expired or unused medications can help reduce the prevalence of prescription drug abuse in Florida. It also helps prevent accidental ingestion by children or pets, helps prevent accidentally taking the wrong medication, and prevents medications from entering water sources. This new 3-page publication of the UF/IFAS Department of Soil and Water Sciences provides some dos and don'ts for disposing of your medications. Written by Alexander J. Reisinger.

Termite Prevention and Control -- This 16-page guide written by F. M. Oi, J. Davis, J. McConnell, J. Corbus, N. Nelson, and M. Atkinson* and published by the UF/IFAS Entomology and Nematology Department is intended to help homeowners make informed choices about the best termite protection for their homes.
