Effects of Invasive Species
The Invasive Species Program determines effects of invasive species and susceptibility of habitats to invasion. As part of their strategic plan, they strive to:
- Research to provide basic understanding of the biology, ecology and population dynamics of invasive species, including studies to determine species' environmental requirements and tolerances.
- Research on how and why nonindigenous species become invasive including biotic and abiotic factors influencing the lag time between introduction and invasion.
- Research on interacting factors (e.g., fire, erosion and deposition processes, atmospheric and climatological stresses, chemical pollution, land use changes, and management practices) that facilitate invasion of a particular species or taxonomic group in U.S. ecosystems.
- Research on factors influencing species invasiveness to facilitate risk assessment and screening of potential new invaders.
- Research to determine the individual and cumulative effects of invasive species on ecosystem processes and native species (Note: invasive species must be the primary factor under study. Research on interacting factors in ecosystem processes should be included in the Ecosystems Program).
