Invasive Species

Research, monitoring, and technology development for containment or eradication of non-indigenous species that have potential to cause significant ecologic or economic damage and those that impact human health. Scientists test and develop methods to better detect invasive species, determine the likelihood of their spread and impact, report distribution to track their spread, methods to contain and control harmful invasive species, as well as means to restore ecosystems after control efforts. Recent emphasis has been on using advanced technologies such as remote sensing and genetics methods to develop species-specific detection and control tools for terrestrial and aquatic species, with recent focus on Asian carp, sea lamprey, and snakes. Includes studies on ecologic impacts, invasion biology, and basic life history to help determine risk and develop control strategies.

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.

Fish Slam - Spring 2016

May 23, 2016 – Five teams of fishery biologists from the U.S. Geological Survey (USGS), Florida Fish and Wildlife Conservation Commission (FWC), the National Park Service (NPS), Florida Museum of Natural History (FLMNH), University of Florida (UF), and Florida International University (FIU) sampled 12 sites for non-native fishes in Broward and Miami-Dade counties in southeastern Florida.

Impacts of Sea Level Rise & Ecosystem Restoration on Wildlife

The interior marshes of the Ten Thousand Islands National Wildlife Refuge (TTINWR) are currently negatively impacted by sea level rise through saltwater intrusion from the south which furthers mangrove encroachment into the freshwater marsh.

Assessment of Small Mammal Demographics and Communities in Everglades National Park

The decline of mammal populations in Everglades National Park (ENP) over the last 20 years is likely to influence the ecology of the Everglades system and the likelihood of successful Everglades restoration.

Detection, tracking, and removal of non-native marine fishes in Florida

Thirty-four species of non-native marine fishes have been documented in Florida, and their distributions are currently being tracked via the US Geological Survey’s Nonindigenous Aquatic Species (USGS-NAS) database.

A Novel Technique to Control Invasive Species – Trojan Y

In this project, USGS scientists are developing a new genetic technique – Trojan Y – to help eradicate invasive species. Although the methodology has been well-developed in theory, this is the first test of its practical application.

Trojan Y Invasive Species Control - Sex Marker Identification

To control or possibly eliminate non-native species without harm to native fauna, a genetic technique using sex-reversed females with two Y chromosomes (Trojan Y) is being developed to reduce the breeding success of the species, ultimately resulting in population decline or loss.
