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.
Describes the value of molecular biology genetic tools in enhancing the delineation of the genetic diversity and the effects of environmental degradation on living species. Links to research, which differentiated two species of sage-grouse.
Article from Status and Trends of the Nation's Biological Resources on the serious impacts to river systems due to damming and flow regulation, and rehabilitation, monitoring, and research on such rivers.
Links to research projects that will improve the ability to detect, monitor, and predict the effects of invasive species, including exotic animals, on native ecosystems of the Pacific Southwest (California, Nevada, Utah, and Arizona).
Plan for an upcoming study, at the microbiological scale, of the benthic communities (including corals) that reside in and around mid-Atlantic canyons, which are located at the edge of the continental shelf.
Information on the Gap Analysis Program in Ohio, a geographic approach to planning for biological diversity by mapping native aquatic and terrestrial animal species and natural communities on present-day conservation lands.
Biomonitoring projects studying the status and trends of the nation's environmental resources and programs studying amphibians and birds. Links to long-term programs, resources and references, and related links.
Change in streams accompanying land and water use may affect benthic invertebrate assemblage composition and structure through changes in density of invertebrates or taxa richness, the number of different species living in the stream.
