- Pine Rockland and Saltwater Intrusion
Institute researchers Dr. Danielle Ogurcak and Dr. Michael Ross have been monitoring dwindling freshwater under the pine rockland as seas rise. Hurricanes are a frequent disturbance in the western Atlantic impacting coastal forest structure and persistence. This project addressed the hypothesis that periodic hurricane-associated winds and storm surges can interact with sea-level rise to cause the demise of coastal pine forests, based on the response of the Florida Keys' last extensive tract of slash pine (Pinus elliottii var. densa) following Hurricane Irma (September 2017).
- Optimizing Fire Regimes in Fire Dependent Ecosystems
Lead: Sparkle Malone
The Everglades provides a unique opportunity to develop an extensive monitoring system that is capable of detecting disturbances, measuring disturbance impacts and estimating recovery times. The detailed 66-year fire history (1948-2013) within Everglades National Park (ENP) can be used to understand changes in post-fire recovery rates across subtropical ecosystems. Leveraging NASA data products and geospatial fire history data from the National Park Service (NPS), this project evaluates patterns in post-fire ecosystem recovery to understand how recovery rates vary between and within Everglades fire dependent areas. Specifically, this research will enhance our understanding about how postfire recovery rates are influenced by fire history, hydrology and climate.

- Everglades Restoration and Water Flow Management
Project Title: Assessing Near-Field and Landscape Scale Ecological Effects of the Modified Water Deliveries and Comprehensive Everglades Restoration Plan Projects in Northeast Shark River Slough, Everglades National Park
This project aims to inform the planning and implementation of Modified Water Deliveries (MWD) and the Comprehensive Everglades Restoration Plan (CERP). Previous Everglades restoration efforts have resulted in an extensive network of canals, levees and impoundments and enhancements to preexisting canal systems to provide flood control and water supply in Florida. Water Conservation Areas were completed in the 1960s, resulting in impoundment and loss of ecological connectivity throughout the central and southern Everglades. The MWD and CERP plans include hydraulic restoration, via increased water flow through constructed and planned elevated bridges to allow more water to pass into the Northern portions of Everglades National Park, specifically the Northeast Shark River Slough (NESRS). This project will monitor ecological conditions before, during and after these hydraulic modifications to assess their ecological impacts.
- Direct Measurement of Net Ecosystem Exchange (NEE)
Lead: Tiffany Troxler
Project Title: Direct Measurement of Net Ecosystem Exchange (NEE) in Coastal Mangroves of Everglades National Park
Everglades National Park is currently undergoing restoration efforts that are meant to create a positive ecological response in the area. These efforts aim to improve the current state of the landscape so that Everglades National Park is protected and effectively performing its environmental services. This research is designed to directly measure how the landscape of Everglades National Park is processing carbon in response to hydrologic and/or salinity changes. This project will monitor and ensure the safe and effective operation of two eddy flux towers (one at Shark River Slough and the other at Taylor River).

- Photochemical Reactions in Aquatic Environments
Lead: Yong Cai
Project Title: Photochemical Reactions of Particulate Mercury Species at the Water-Particle Interface in Aquatic Environments
As a long recognized notorious pollutant posing health risk to millions of people worldwide, mercury (Hg) undergoes a complicated biogeochemical cycle through major environmental compartments. Understanding the global budgets of Hg cycling is extremely complicated and made even more so as potential errors arise when studying the air-water Hg exchange. Our project studies the most complex aspect of the air-water HG exchange: the unresolved role of particulate mercury (pHg) species in photochemical transformation of Hg. The potential involvement of pHg(II) and pHg(0) species in Hg photoreactions has been largely overlooked, so our researchers aim to better understand this relationship.
- Hurricanes Fertilize Mangrove Forests in the Gulf of Mexico
Lead: Dr. Edward Castaneda
Dr. Edward Castaneda studies the impacts that hurricanes can have on mangrove forests. Despite the destructive effect of hurricanes on mangrove forests in tropical and subtropical latitudes, hurricanes are major drivers controlling soil fertility gradients in the Florida Everglades mangroves, and therefore represent a positive influence in maintaining observed mangrove spatial distribution and productivity patterns. Hurricane-induced mineral inputs to near-coast mangroves in the Everglades enhance soil P concentrations in soils, increase plant P uptake, promote soil elevation gains relative to sea level, and facilitate rapid forest recovery following disturbance. The response of mangroves to large-scale P fertilization from hurricanes may be an important adaptation of neotropical mangroves in the Gulf of Mexico and the Caribbean region to withstand the impacts of both sea-level rise and P limitation.
- Vegetation Response to Changes in Hydrological Parameters
Lead: Jay Sah
Project Title: Evaluation of Vegetation Response to Changes in Hydrologic Parameters within Cape Sable Seaside Sparrow Habitat, Everglades National Park, Florida
This research focuses on understanding whether the water management activities aimed at mitigating damage to Everglades ecosystems caused by past management would affect the Cape Sable seaside sparrow (CSSS) habitat. Our project also studies how the impact on vegetation structure and composition will vary geographically and over time in relation to the preferred CSSS habitat conditions. This study will include vegetation re-sampling at the subset of existing network of vegetation monitoring sites as well as some new sites to be established in the potential CSSS habitat likely to be impacted by future managements. The periodic monitoring of these sites is helpful in determining the impact of ongoing as well as future restoration activities.

- Analyzing Change of Hydrologic Conditions in the Everglades
Lead: Joel Trexler
Project Title: Analyzing the Impact of Changing Hydrologic Conditions along the Boundary of Everglades National Park
This project provides a decade long view of the status of fish and aquatic invertebrates along the eastern boundary of Everglades National Park. Fish, macroinvertebrates, and periphyton are used as indicators of management success in efforts to improve this area of the National Park and provide more water to downstream sites. The data it produces are used in reports evaluating progress from management initiatives associated with environmental management plans implemented to conserve the Cape Sable Seaside Sparrow and assure adequate water delivery to sensitive areas like Florida Bay.
- CREST CAChE Supplements
Mangrove Ecology Supplement: Our CREST Center for Aquatic Chemistry and Environment is designed to measure the levels of contaminants in the fragile South Florida aquatic system, and develop appropriate remediation strategies for them. Specifically, CAChE will characterize and quantify contaminants and excessive nutrients, measure their transport and transformations, and model their likely impacts on ecosystem services in a gradient of urbanized freshwater ecosystems. In this Partnership Supplement focusing on Mangrove Ecology, we seek to enhance the Center by expanding the expertise on our research team to add an exploration of mangrove ecosystems, which serve as the filter and connection between the freshwater and marine ecosystems.
Near-Shore Systems Supplement: In this Supplement, we seek to further enhance the University of Puerto Rico-FIU partnership by expanding into the new research area of investigating the role of contaminants and pollutants on estuary and coral reef ecosystems. FIU CREST researchers currently utilize metagenomics methodologies to identify early indicators of ecosystem impacts due to anthropogenic stressors. The UPR CREST program investigates similar phenomena in river, estuarine and coral reef systems but utilizes neurologic indicators to predict stress.
Urban Supplement: In this Supplement, CREST researchers seek to investigate the role that contaminants and pollutants play in urban waterways. CREST scientists are currently looking at areas such as the Miami River and Biscayne Bay in order to determine their water health and quality.

- Understanding Extreme Weather Events
Lead: Shimon Wdowinski
Project Title: Cascading hazards: Understanding triggering relations between wet tropical cyclones, landslides and earthquakes
Two recent devastating earthquakes and other moderate size earthquakes occurred in tropical mountainous areas shortly after wet tropical cyclones (hurricane or typhoon) hit the same areas. This project is aimed at studying two ideas: 1) massive erosion induced by wet tropical cyclones can trigger earthquakes in seismically active mountainous areas, and 2) pore fluid increase induced by wet cyclones can trigger earthquakes in the same tectonic environment.
