Quantitative Framework to Model Risk of Collisions between Marine Wildlife and Boats
Collisons between wildlife and vehicles threaten many species, and can lead to human loss of life, injuries, and loss of property. USGS is developing models to help evaluate the effectiveness of wildlife protection zones and optimize the design of these protected areas.
A Structured Decision-Making Framework for Controlling, Monitoring, and Containment of Invasive Species through Trapping: An Application to the Argentine Black and White Tegu
USGS is applying decision analysis to identify cost-effective methods for controlling invasive species like the Argentine black and white tegu.
Climate Change Adaptation for Coastal National Wildlife Refuges
National Wildlife Refuges provide habitat for important fish and wildlife species and services that benefit coastal communities, like storm-surge protection. USGS scientists are helping coastal refuges plan for and adapt to sea-level rise.
Decision Analysis to Help Improve the Effectiveness of Invasive Plants Management
Melaleuca is an invasive tree that is highly problematic in the Everglades, threatening native wildlife and habitat. USGS is helping to improve management strategies for the invasive plant.
USGS Technical Support for Coastal/Wetlands Ecology: Spatial Analysis and Application for the Gulf Coast Prairie Landscape Conservation Cooperative (GCP LCC)
The Gulf Coastal Prairie (GCP) includes areas within Kansas, Louisiana, Mississippi, Oklahoma, and Texas as well as Mexico. The GCP Landscape Conservation Cooperative aims to conserve prairie grasslands which helps migratory birds and other wildlife that rely on these ecosystems.
Quantitative Analysis Using Structural Equation Modeling
USGS scientists have been involved for a number of years in the development and use of Structural Equation Modeling (SEM). This methodology represents an approach to statistical modeling that focuses on the study of complex cause-effect hypotheses about the mechanisms operating in systems. SEM is increasingly used in ecological and environmental studies and this site seeks to provide educational...
Modeling Past Variation in Florida Manatee Survival, Breeding, and Movements Rates to Establish Baselines for Aquatic Ecosystem and Restoration Research
Long-term monitoring data in the Manatee Individual Photo-identification System (MIPS), developed and coordinated by WARC-Sirenia Project in collaboration with Florida’s Fish and Wildlife Research Institute and Mote Marine Laboratory, are the basis for modeling manatee demography rates.
Structured Decision Making for Management of Warm-Water Habitat of Manatees
Manatees are tropical to subtropical in distribution and, with few exceptions, Florida is the northern limit of their natural winter range. The availability of warm-water habitat during winter is critical for the future persistence of the population in Florida.
Joint Ecosystem Modeling: Greater Everglades Modeling Decision Support Tools
The Joint Ecosystem Modeling team is developing and applying ecological models and other decision support tools for Greater Everglades restoration project planning.
Optimal Control Strategies for Invasive Exotics in South Florida
The establishment and proliferation of exotic plants and animals can interfere with native ecological processes and can cause severe stress to sensitive ecosystems.
Training in Structured Decision Making and Adaptive Management
The goal of this project is to educate resource professionals in the tools and techniques of structured decision making and adaptive management.
Climate Envelope Modeling for Evaluating Anticipated Effects of Climate Change on Threatened and Endangered Species
Modeling both potential changes in climate and responses of species and habitats can increase certainty in management decisions by helping managers to understand the range of possible species and habitat responses under different alternative futures. Climate envelope modeling is one type of modeling that can be useful in understanding species and habitat responses to climate change because it...
