Background information and genetic sequencing data for more than 1,000 individual field isolates of the fish virus Infectious Hematopoietic Necrosis Virus (IHNV) collected in western North America from 1966 to the present, updated annually.
Using genetic analysis of organic material found in aquatic environments it is possible to detect the presence of organisms without necessarily observing or capturing individuals. Explains terms, methods, and prospective utility of this approach.
Previous analysis showed this area to have reduced macroinvertebrate biodiversity, an important measure of ecosystem health. New observations indicate that conditions have improved; report includes methods and results of sampling.
Detailed information on capture-and-release surveying as well as acoustic monitoring of bats indicates prevalence of various species and, for the captured specimens, physiological characteristics.
A chapter of the publication: Land Use History of North America on general patterns of plant species diversity in North America that shows how these patterns have changed over time.
Coverage of the Coastal Prairie Ecology Research (CPER) Team, National Wetlands Research Center, providing scientific information to aid the conservation, management, and restoration of ecosystems in the greater coastal prairie region.
Describes research to assess the effectiveness of the current system and distribution of marine reserves and protected areas in the Virgin Islands and Puerto Rico for conserving reef ecosystems and resources.
This program is focused on the study of fishes, fisheries, aquatic invertebrates, and aquatic habitats, and evaluates factors that affect aquatic organism health, population fitness, biological diversity, and aquatic community and habitat function.
Program to keep common species common by identifying those species and plant communities that are not adequately represented in existing conservation lands. Links to projects, applications, status maps, and a searchable database.
Explains the types of genetic analysis we carry out, and how those methods help us understand biological populations so that people who manage those populations can devise effective strategies.
