North American Waterfowl Management Plan
The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats.
Quantitative and Statistical Research Collaboration
Mathematical and statistical models are powerful research tools that play several important roles in conceptualizing and understanding the structure and dynamics of complicated ecological systems, including developing mechanistic hypotheses pertaining to ecological systems, designing studies that elucidate ecosystem structure and function, and extracting information from data.
Ecology and Control of Invasive Reptiles in Florida
This project involves ongoing development of tools for the detection and capture of invasive reptiles in Florida, with an emphasis on Burmese pythons (Python bivittatus) and Black and white tegu lizards (Salvator merianae). The goals are to reduce the risk of reptile invasions in high-value resources such as Everglades National Park and the Florida Keys, to access early detection methods of...
Control and Landscape-Scale Suppression of the Invasive Brown Treesnake
The Brown Treesnake is a highly destructive reptile species that has extirpated many native species of birds, bats, and lizards from the U.S. Territory of Guam. For more than two decades branch scientists with the Invasive Reptile Project have developed, validated, and tested the feasibility of Brown Treesnake control and suppression at various spatial scales.
Status and Trends of Emergent Wetlands in the Northern Gulf of Mexico: 1950-2010
Throughout the past century, emergent wetlands have been declining across the Gulf of Mexico. Emergent wetland ecosystems provide a plethora of resources including plant and wildlife habitat, commercial and recreational economic activity, water quality, and natural barriers against storms.
Monitoring of Amphibians at St. Marks National Wildlife Refuge in Northwest Florida
Freshwater wetlands provide critical habitat for a diverse array of organisms, including many amphibians. Yet, under the threat of climate change, these habitats are among the most imperiled ecosystems on Earth.
Statistical Models for the Design and Analysis of Environmental DNA (eDNA) Surveys of Invasive and Imperiled Species
Detecting invasive species at low densities or prior to population establishment is critical for successful control and eradication. For example, Burmese pythons occupy thousands of square kilometers of mostly inaccessible habitats.

Adapterama II: Universal amplicon sequencing on Illumina platforms (TaggiMatrix)
Next-generation sequencing (NGS) of amplicons is used in a wide variety of contexts. In many cases, NGS amplicon sequencing remains overly expensive and inflexible, with library preparation strategies relying upon the fusion of locus-specific primers to full-length adapter sequences with a single identifying sequence or ligating adapters onto PCR...

Catalog of microscopic organisms of the Everglades, part 2—The desmids of the Arthur R. Marshall Loxahatchee National Wildlife Refuge
The Arthur R. Marshall Loxahatchee National Wildlife Refuge (refuge), Boynton Beach, Florida, contains approximately 147,000 acres southeast of Lake Okeechobee. Water quality in the interior portion of the refuge is strongly influenced by rainfall, resulting in slightly acidic waters with low dissolved ions. Desmids, a unique, ornate group of...

Withdrawal and consumption of water by thermoelectric power plants in the United States, 2015
The U.S. Geological Survey has developed models to estimate thermoelectric water use based on linked heat and water budgets. The models produced plant-level withdrawal and consumption estimates using consistent methods for 1,122 water-using, utility-scale thermoelectric power plants in the United States for 2015. Total estimated withdrawal for...

Groundwater/surface-water interactions along Ellerbe Creek in Durham, North Carolina, 2016–18
An assessment of groundwater/surface-water interactions along Ellerbe Creek, a major tributary to upper Falls Lake in Durham County, North Carolina, was conducted from July 2016 to March 2018 to determine if groundwater is a likely source of elevated nitrate input to the stream. Groundwater/surface-water interactions were characterized by synoptic...
Antolino, Dominick J. Standardizing a non-lethal method for characterizing the reproductive status and larval development of freshwater mussels (Bivalvia: Unionoida)
Actively monitoring the timing, development, and reproductive patterns of endangered species is critical when managing for population recovery. Freshwater mussels are among the most imperiled organisms in the world, but information about early larval (glochidial) development and brooding periods is still lacking for many species. Previous studies...
Beaver, Caitlin; Geda, Susan; Johnson, Nathan Prediction and inference of flow-duration curves using multi-output neural networks
We develop multi-output neural network models (MNNs) to predict flow-duration curves (FDCs) in 9,203 ungaged locations in the Southeastern United States for six decades between 1950-2009. The model architecture contains multiple response variables in the output layer that correspond to individual quantiles along the FDC. During training,...

Coastal Salinity Index along the southeastern Atlantic coast and the Gulf of Mexico, 1983 to 2018
Coastal droughts have a different dynamic than upland droughts, which are typically characterized by agricultural, hydrologic, meteorological, and (or) socioeconomic effects. Drought uniquely affects coastal ecosystems because of changes in the salinity conditions of estuarine creeks and rivers. The location of the freshwater-saltwater interface...
