Hurricane Impacts on Florida's Agriculture and Natural Resources

Young Gu Her, Ashley Smyth, Pamela Fletcher, Elias Bassil, Ulrich Stingl, Zachary Brym, and Jiangxiao Qiu

Understanding hurricane effects is the first step to preparing for hurricanes. The effects of hurricanes can be comprehensive and long-lasting, even permanent, at the spatial scales of a single molecule to whole ecosystems. Multidisciplinary collaborations are required to improve our understanding of hurricanes. Here, we review basic facts of hurricanes and their effects in Florida and speculate on how they might affect Florida’s agriculture and natural resources. Examples and speculations provided in this article demonstrate how weather, agriculture, environment, and ecosystem are connected to each other across spatial scales ranging from microorganisms to an entire landscape.

How Ecosystem Services are Measured and Why it Matters for Florida

Charles Wallace, Anna Braswell, Mysha Clarke, Andrew Ropicki, Tara Wade, Frank Asche, Ashley Smyth, Armando Ubeda, and Ed Camp

Florida has many ecosystems that are thought of as especially important such as springs, coasts, dry prairies, and the Everglades. One of the ways importance is measured is through value. The term ecosystem services describes the benefits ecosystems and their components provide humans. This publication describes some of the ways to measure ecosystem services and explains how the different approaches to assess ecosystems might be selected, depending on what is most important to the user. This publication should help Extension and outreach agents, as well as agency personnel better understand ecosystem services values and explain them to the public. It should also help interested members of the public who wish to learn more about ecosystem services for themselves.

Linking Waterbody Acidification and Aquatic Plant Metabolism: A Lesson Plan for Middle School Students

Alexandra L. Bijak, Laura K. Reynolds, and Ashley R. Smyth

Ocean acidification, the lowering of seawater pH due to increased concentrations of carbon dioxide in the atmosphere, is an emerging environmental challenge associated with climate change. This publication is intended for Florida grade eight educators and other environmental educators of middle school students. We designed a lesson plan to reinforce fundamental concepts in acid-base chemistry, including the pH scale, and to introduce students to waterbody acidification, its negative effects on shell-forming organisms, and the potential role of aquatic plant metabolism (i.e., photosynthesis and respiration) in mitigating these effects. The goal of the lesson plan is to encourage students to link water chemistry and biological processes while learning about the challenges and potential solutions to acidification within a local context. This lesson plan will contribute to state learning standards while generating appreciation for the complexity of the natural environment. 

What are urban mangroves?

Gabriela Reyes, Ashley Smyth, and Laura Reynolds

Urban mangroves are mangroves located in cities and residential areas. While urban mangroves may be highly impacted by humans, they continue to provide important ecosystem services, or benefits to society. In fact, due to their location, more people may benefit from these urban mangroves than from pristine mangroves, which are often located in protected areas. The following document describes the role of mangroves in urban areas. This document is intended for coastal residents, coastal resource managers, and urban planners who are interested in learning about mangroves and their importance in cities.

Climate Change: Effects on Salinity in Florida’s Estuaries and Responses of Oysters, Seagrass, and Other Animal and Plant Life

Ashley R. Smyth, H. Dail Laughinghouse, Laura K. Reynolds, Edward V. Camp, and Karl Havens

Florida’s economically important estuaries could be heavily impacted by sea-level rise and altered river flow, both caused by climate change. The resulting higher salinity, or saltiness of the water, could harm plants and animals, alter fish, and bird habitat, and reduce the capacity of estuaries to provide such important services as seafood production and the protection of shorelines from erosion. This publication contains information for stakeholders, students, scientists, and environmental agencies interested in understanding how changes in salinity impact Florida’s estuaries.

How Do Oysters Remove Nitrogen?

Heather Donnelly, Ashley Smyth, Shirley Baker, Laura Reynolds, and Angela Collins

Nitrogen is natural and necessary, yet nitrogen levels above natural levels can cause algal blooms and eutrophication of coastal systems. The purpose of this document is to describe how oysters and oyster reefs remove nitrogen. This new 7-page publication of the UF/IFAS Department of Soil, Water, and Ecosystem Sciences is intended for policymakers, environmental organizations, and coastal residents who want to know about oysters' role in improving water quality through nitrogen removal. Written by Heather Donnelly, Ashley Smyth, Shirley Baker, Laura Reynolds, and Angela Collins.

The Coral Holobiont: A Brief Overview of Corals and Their Microbiome

Monica D. Schul, Ashley R. Smyth, Joshua T. Patterson, Ana N. Zangroniz, Shelly L. Krueger, and Julie L. Meyer

Caribbean and tropical western Atlantic reefs have declined drastically since the 1970s. In some locales like the Florida Keys, the decline of branching corals approached 98%. These declines are widely attributed to recurring stressors such as high ocean temperatures and disease. The preservation and restoration of reefs is imperative as coral reefs support 25% of the world's known marine species and create billions of dollars in economic value. However, current restoration efforts have low success rates, so researchers are looking to better understand how stony corals respond to and overcome these stressors. Pioneering efforts to elucidate the role of the coral microbiome have shown that microbes are an important component for stony coral health, nutrition, and disease defense. This publication is for various natural resource professionals who want information on corals, microbiomes, and how coral microbial ecology research is pushing our knowledge of corals and restoration forward.

Living shorelines are an increasingly popular way to protect and stabilize waterfronts for coastal property owners. Living shorelines provide valuable benefits to humans, including water quality improvement, habitat, fisheries, and carbon sequestration. Estimating the economic value of the ecosystem services living shorelines offer is an integral part of management decisions. The living shoreline valuation tool can help quantify the costs and benefits of living shorelines projects. This publication briefly describes the ecosystem services associated with living shorelines. The purpose of this publication is to introduce the ecosystem service valuation tool. Our target audience for the living shoreline evaluation tool includes natural resource extension agents, community organizations, and coastal homeowners who want to calculate the value of ecosystem services provided by coastal restoration projects, including living shorelines. 

Repensando el papel del nitrógeno y fósforo en la eutrofización de los ecosistemas acuáticos

H. Dail Laughinghouse IV, Ashley Smyth, Karl Havens y Thomas Frazer

Históricamente, las agencias ambientales han buscado mejorar la calidad del agua de los lagos y ríos de agua dulce mediante el manejo de un solo nutriente. El fósforo era el nutriente principal de preocupación en los sistemas de agua dulce y el nitrógeno estaba regulado en los sistemas costeros y estuarios. Investigaciones recientes indican que debemos reducir tanto el fósforo como el nitrógeno para revertir los síntomas de eutrofización en todos los sistemas acuáticos. This new 5-page publication of the UF/IFAS Department of Soil and Water Sciences, written by H. Dail Laughinghouse IV, Ashley Smyth, Karl Havens, and Thomas Frazer, is a translation of SGEF190/SG118, "Rethinking the Role of Nitrogen and Phosphorus in the Eutrophication of Aquatic Ecosystems."

Oyster Habitat Restoration and Shoreline Protection

Charles Wallace, Edward Camp, and Ashley Smyth

As the climate continues to change, coastal areas and the people that live there face increasing risks from erosion and wave damage. This is made worse by declines in natural oyster reefs, which would provide some natural protection. However, oysters can be restored for the specific purposes of protecting shorelines. The practicality and cost effectiveness of using oysters in this way is described in this publication, which is intended to be used by coastal property owners, as well as local governments that must make decisions about protecting shorelines in the face of a changing climate.
