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.

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.

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...

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

Ecological models are needed to facilitate evaluation and assessment of alternative approaches to restore Greater Everglades ecosystems. However, the provision of useful and accessible models is a challenge because there is often a disconnect between model developers and model users. Joint Ecosystem Modeling (JEM) was established to meet this challenge, with the goal of getting ecological...
