Our work in cloud forests of the Amazonian slopes of the Andes and throughout the Andean cordillera is quantifying the impact of chytridiomycosis disease on amphibian biodiversity, and tracing the spread of the fungal pathogen and associated amphibian declines in the region.
- Disease Ecology in Megadiverse Tropical Amphibian Communities
Lead: Alessandro Catenazzi
Project Title: Disease ecology in megadiverse tropical amphibian communities
The pathogenic fungus Batrachochytrium dendrobatidis has been associated with amphibian population declines and extinctions throughout the world. Such declines have been particularly dramatic in the tropical Andes, which are among the most amphibian rich regions in the world. Our work in cloud forests of the Amazonian slopes of the Andes, and throughout the Andean cordillera is quantifying the impact of disease on amphibian biodiversity, and tracing the spread of the fungal pathogen and concomitant amphibian declines in the region.
A major ongoing effort is to examine the disease dynamics of fully terrestrial amphibians, a guild of tropical frogs that have been experiencing cryptic population declines and extinctions ostensibly linked to disease, droughts, shifts in host behavior, spatial aggregation, and pathogen spillover. We are comparing spatiotemporal disease dynamics among co-occurring terrestrial-breeding and aquatic-breeding amphibian species, with particular attention on divergent host movement patterns and responses to climatic variability. We will use field survey and experimental data to produce a multi-host disease modeling framework using recently developed models accounting for imperfect host and pathogen detection, and population viability analyses to examine long-term host population stability under future climate trends.

- Dominica's Parrots
Residing exclusively on Dominica, the Imperial parrot is this Caribbean island’s national bird. It's also one of the most endangered in the world. The Rare Species Conservatory Foundation has been partnered with Dominica’s Forestry, Wildlife and Parks Division for over 20 years, studying and protecting the parrots and helping establish protected areas for wildlife. The partnership is now launching a post-Hurricane Maria rapid wildlife assessment, to be followed by long-term monitoring and additional conservation actions.
- Dwarf Crocodiles
The Congo dwarf crocodile (Osteolaemus osborni), a partially protected species endemic to the Congo Basin, is an important top-down and bottom-up trophic regulator and is traded in the tens of thousands annually as a key local and regional wild meat resource. Ensuring the sustainability of this important wildlife resource has significant implications for local livelihoods and wildlife conservation in places like Congo's Lac Tele Community Reserve.
- Evolutionary Reversals of Growth in Lizards
Lead: Christian Cox
Project Title: "Evolutionary Reversals" in the Hormonal Regulation of Growth Across Lizard Species
The hormone testosterone is classically viewed as a promoter of growth, but this generalization is based on model species in medicine, agriculture, and aquaculture. In most of these model species, males also happen to be larger than females. However, in several lizard species in which females are larger, testosterone inhibits growth. This raises the intriguing possibility that, far from being hard-wired, the effects of testosterone (and other hormones) on growth and other processes may change considerably during evolution.
This project will test for such "evolutionary reversals" in the hormonal regulation of growth across lizard species. These species have been selected to span repeated evolutionary shifts between those in which males are larger and those in which females are larger. By simultaneously characterizing the effects of testosterone on the expression of thousands of genes, this project will also determine how such "evolutionary reversals" in the hormonal regulation of growth are accomplished at the genetic level. The results of this collaborative study will broaden understanding of the endocrine system. It may also challenge generalizations derived from traditional animal models by investigating how closely related species evolve different responses to the same hormone. The project will also contribute to filling national teaching needs and will involve high school teachers in research experiences in an intensive summer program.

Pangolins are the world’s only scaly mammal and are in dire need of urgent conservation action. Eight species occur in Africa and Asia, where they have been exploited locally for food and traditional medicine throughout history. Despite their importance to local communities as a protein source, their ecological role in tropical forest trophic webs, and their general charisma, pangolins are likely the least-known mammals in the world. We are researching pangolin basic biology, resource use, and utilization by local communities in Cote d'Ivoire to better support their in and ex situ management.
- Pygmy Hippos
The pygmy hippopotamus (Choeropsis liberiensis) is listed as Endangered on the IUCN Red List and is one of the least studied of Africa's charismatic, endangered fauna. Continuing population declines are due to habitat loss and degradation, industrial agriculture, logging, mining and an ever-expanding human population. We are implementing the most comprehensive study of wild pygmy hippo to date, producing the necessary ecological, health and abundance data to support the implementation of in and ex situ conservation action.
- Red-browed Amazon Parrots
Our scientists are leading a 25-year captive-breeding program for the Red-browed parrot, South America’s most endangered Amazon parrot. Starting with 11 birds 30 years ago, we have produced a self-sustaining captive population and integrated recovery techniques and methods with Brazilian partners. The Red-brow is now recovering in the wild.
- Slender-Snouted Crocodiles
African slender-snouted crocodiles (Mecistops spp.) are the least-known crocodile species, and our estimates suggest that fewer than 500 adult West African slender-snouted crocodiles (Mecistops cataphractus) are left in the wild. We aim to ensure the survival of the Critically Endangered West African slender-snouted crocodile through scientific research, capacity building and support of West African national partners.
- Small Primates
Our scientists have participated in the international Lion Tamarin Conservation Program for more than 25 years. This program works closely with agencies in Brazil to protect wild populations and expand protected areas. Our efforts in small primate conservation also benefit the pygmy marmoset; we have maintained North America's largest pygmy colony for over 25 years.
- Atlas of Florida Plants
Lead: Alan Franck
Project Title: Atlas of Florida Plants
Humans have occupied Florida and studied its flora for the past 14,000 years. Today there are over 3,200 species of land plants native to Florida, more than 200 being endemic to the state and more than 500 considered endangered or threatened by the state. An exceptionally high number of naturalized, non-native plant species also occur in Florida (over 1,500 species) with several added each year. The flora is dynamic and much remains to be studied. The Atlas of Florida Plants is a regularly updated website that provides information on each native and naturalized plant species occurring in Florida.
- Environmental Education in Urban Food Forests
Lead: Cara Rockwell
Project Title: Environmental Education in Urban Food Forests: measuring students’ knowledge and attitudes about the natural sciences in a participatory setting
Food forests are perennial, multi-storied agroforestry systems that provide a broad diversity of services and mimic the structure and diversity of a natural forest system. In partnership with The Education Fund, Dr. Rockwell recently received funding from the U.S. Environmental Protection Agency to measure elementary school students’ knowledge about the natural sciences via these outdoor eco-labs. To help support this effort, the FIU team is collecting data on the plant and insect communities in several food forests, which will help determine the integrated pest management benefits of this system. Results from the study will contribute directly to ongoing teacher workshops and improvement of students’ knowledge of pesticide-free food production systems in this subtropical climate.
- Fungi of Florida
Lead: Alan Franck
Project Title: Fungi of Florida
Fungi are one of the most diverse kingdoms of life, nearly as ubiquitous as prokaryotes and spanning a wide range of ecological roles. About 90% of the species are solely microscopic, while the remaining species are macrofungi (e.g. mushrooms) that are readily seen without magnification. In total, there are probably around 10,000-20,000 species of fungi in Florida. Despite their widespread importance, the diversity of fungi in Florida is very poorly known. As biodiversity is inextricably linked to ecosystem processes and human wellbeing, improved knowledge of fungal diversity and their ecological roles is essential. Field work and morphological and molecular analyses will greatly improve knowledge of Florida fungi.

- Plant Taxonomy and Conservation
Lead: Javier Francisco-Ortega
A native of the Canary Islands, Prof. Javier Francisco-Ortega has developed most of his projects on taxonomy, population genetics and phylogenetics of island plant. Member of his lab has been primarily working with species restricted the Macaronesian region (Azores, Canaries, Cape Verdes, and Madeira) to the Caribbean Islands. His laboratory is located in Fairchild Tropical Botanic Garden and the vast majority of these projects are being performed with botanists of this botanic garden. Montgomery Botanical Center (Miami) is also major research partners. It is well known that island floras have a high proportion of threatened species; therefore a high proportion of these endeavors target plants groups that are Critically Endangered or Endangered. All of these initiatives are conducted with partners working in research institutions from the region.
To learn more on Caribbean Island projects performed by Prof. Francisco-Ortega's lab, read this article published in the 2019 issue of Hemisphere devoted to Climate Change in Latin America and the Caribbean (pages 6-8).

- Post-logging Forest Recovery
Lead: Cara Rockwell
Project Title: Post-logging Forest Recovery: legacies of 20th century natural resource exploitation in Big Cypress National Preserve
South Florida claims extensive areas of recuperating forest that were heavily logged in the 19th and 20th centuries, including bald cypress (Taxodium distichum) tracts in Big Cypress National Preserve. Together with our research partners from Big Cypress National Preserve, we are implementing a pilot study of forest recovery in secondary cypress forest. We are also partnering with the FIU’s Special Collections Department, which houses the historical archives of a former student, Cesar Becerra. Cesar interned at Big Cypress in the 1990s, interviewing retired loggers about the logging history of the Preserve. These primary sources will provide insight into the historical logging practices in the Preserve and help inform management practices. This research will provide critical information on secondary forest health in Big Cypress National Preserve and inform conservation and management strategies.
Seed funding for this project has been provided by the Curtis & Edith Munson Foundation.

- Trees of FIU
Lead: Alan Franck
Project Title: Trees of FIU
Urban forests are incredibly economically valuable, with generally positive impacts to human health, soil stability, stormwater reduction, storm surge reduction, wind mitigation, carbon sequestration, cooling costs, property value, wildlife habitat, and education. Since FIU held its first classes in 1972, it has been planting trees across the campus, much of it catalyzed by the work of Charles M. Henington, the first supervisor of grounds. The MMC campus now is home to nearly 10,000 trees, including a forest of native tree species at the FIU Nature Preserve. Our goal is to inventory all trees on the FIU campuses to understand the species diversity and their value to humans and the environment.

- Conservation Planning for Biodiversity
Lead: Clinton Jenkins
Project Title: Conservation Planning for Biodiversity
We share this planet with millions of other species, yet we know surprisingly little about most of them. Most do not even have names. At the same time, the growth of human civilization has placed much of this biodiversity at risk of extinction. This research program focuses on understanding the distribution of life on the planet, where it faces risks, and where to best save species from possible extinction. Groups that we have studied so far include most of the world’s terrestrial vertebrates, many marine species, ants, and a large portion of global plant diversity.
Results, maps, and publications can be found here.

- Integrating Responses to Environmental Change Across the Biological Hierarchy
Lead: Christian Cox
Project Title: RoL: Collaborative Proposal: Integrating responses to environmental change across the biological hierarchy: interactions between behavior, plasticity, and genetic change
Throughout the history of life on earth, organisms have experienced rapid changes in their environments. These can include changes in abiotic or biotic variables that arise from local shifts in climate, the colonization of new habitats, or anthropogenic disturbances (e.g., habitat alteration, pollution, invasive species). Many populations have persisted in the face of ancient climatic fluctuations, and others have experienced environmental change as they disperse and establish on new continents and islands, with successful colonizers often radiating into new branches on the tree of life. In the modern world, human activities are dramatically altering many environments, and it is important to be able to predict the effects of these changes on the viability of populations.
Here, we build on an existing transplant experiment that moved Anolis lizards from a single source population to islands in the Panama Canal that vary in habitat structure and local climate.

- Sustainable Brazil
Lead: Clinton Jenkins
Project Title: Sustainable Brazil
Brazil is the most biological diverse country in the world, home to tropical forests in the Amazon and Atlantic Forest, as well as the unique ecosystems of the Cerrado savanna, Caatinga scrublands, and the Pantanal. At the same time, the country has a growing human population and rapidly developing economy, placing stress on those natural systems. Our group focuses on understanding those threats to the natural environment, including policy evaluation and recommendations. This work ranges from collaborating with the Brazilian government to assess Priority Conservation Areas, evaluating infrastructure impacts in the Amazon, to measuring the benefits of restoration for connectivity and ecosystem services. The goal is to guide Brazil to a more sustainable future for both nature and people.
- Connecting undergraduate students with plants: Alleviating plant blindness
Title: Connecting undergraduate students with plants: Alleviating plant blindness
Plant blindness is the widespread lack of awareness of plants in one’s environment by the general public. At an undergraduate level this has consequences regarding how our highly skilled future workforce will value plant conservation, services, and research. Starting in 2016, the team has developed educational initiatives centered in Fairchild Tropical Botanic Garden (FTBG) to identify and alleviate plant blindness among freshman undergraduate students. This educational project focuses on FIU undergraduates who are taking one of the two introductory courses of biology. Graduate/undergraduate students and botanists working in FTBG have also actively engaged in this initiative. Preliminary results have led to a project funded by NSF to discuss future educational actions on this issue. This new project involves the participation of other US universities and botanic gardens.
Learn more about results of this project in The Tropical Garden, the magazine of Fairchild Tropical Botanic Garden.
- Farmers' Outreach Program
Project Title: Farmers' Outreach Program
The Farmer’s Outreach Program aims to empower small and under-represented farmers in urban sustainable agriculture, as well as beginning farmers who are interested in starting their own business. This program is predominantly geared towards assisting veterans, small farmers, minorities, and the socially disadvantaged by offering hands-on farming experience through apprenticeships, agricultural-related workshops, and technical one-on-one advice on USDA loans/grant programs. We have collaborated with several farms, nurseries, and organizations throughout South Florida to provide this engaging and practical learning experience.
The apprenticeship entails of 100 paid hours working alongside experienced farm hosts to learn what it takes to be a South Florida grower. Once completed, apprentices may choose to apply for the second stage of the program. This advanced apprenticeship provides the opportunity for apprentices to develop their own agricultural business plan and have a deeper understanding on what it takes to run a farm or nursery business. This program has been supported through various grants from the USDA Office of Partnerships and Public Engagement (2501 Program) and USDA National Institute of Food and Agriculture’s Beginning Farmers and Ranchers Program.

- FIU Organic Garden
Project Title: FIU Organic Garden
The FIU Organic Garden was established by the Agroecology Program in 2005 to provide a hands-on teaching facility for students to gain experiential and experimental learning in sustainable food production and its relationship to the ecosystem through gardening, field research, and challenge-based community engagement. In 2019, a massive effort was undertaken to redesign and improve Organic Garden resources. With the University’s support, we have built 27 new raised beds, one meeting accessibility standards set through the Americans with Disabilities Act. Numerous nursery benches were constructed for the shade house, seeds stores were restocked, and 26 tropical fruit trees were transplanted into the food forest. An herb spiral, composting area, and drip irrigation system are also currently being installed.
The Organic Garden is committed to promoting a tranquil and inviting environment for agricultural learning and often serves as a setting for technical workshops open to both students and the general public. The FIU Organic Garden is designated as USDA People’s Garden and has been supported through various USDA National Institute of Food and Agriculture’s grants over the years.

- Supply Chain Study
Lead: Mahadev Bhat
Project Title: Florida Tomato and Strawberry Supply Chain Study: Strategies for a Resilient Future
FIU is working to ensure people can work and eat despite climatic and logistical challenges.
With support from The Walmart Foundation, researchers in FIU's College of Arts, Sciences & Education and the College of Business conduct a thorough assessment of Florida's tomato and strawberry production systems. They evaluate the entire supply chain - from farmer to processor, distributor, retailer and consumer - to identify what works, what doesn't, and why.
Tomato and strawberry, are the two major cash crops grown in Florida. Florida is the second largest producer of tomato and strawberry in the US after California, and Florida contributes almost 90% of the domestic winter tomato and strawberry supplies. However, 50% of the Florida tomato production was declined over the years due to the market pressure from cheaper imports, weather uncertainties, and growing costs of inputs and labor. This project is currently evaluating (a) environmental and social sustainability components of Florida tomato and strawberry industries, (b) the impact of climate change on production scenarios and (c) the resiliency in supply chain system, and (d) the feasibility to develop a comprehensive sustainability certification on fresh produce.
