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 study reconstructs past interactions among ecosystem factors, native species, and human land use in the Greater Yellowstone ecosystem to provide a context for future management to sustain both ecological and human communities.
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.
