The USGS National Wildlife Health Center: Advancing wildlife and ecosystem health
In 1975, the Federal government responded to the need for establishing national expertise in wildlife health by creating the National Wildlife Health Center (NWHC), a facility within the Department of the Interior; the NWHC is the only national center dedicated to wildlife disease detection, control, and prevention. Its mission is to provide...Moede Rogall, Gail; Sleeman, Jonathan M.

Burrowing mayflies (Hexagenia) as indicators of ecosystem health
Three State of the Lakes Ecosystem Conferences have been held since 1996 to encourage the development of Great Lakes indicators of ecosystem health for use in reporting on progress in restoring and maintaining the chemical, physical and biological integrity of the Great Lakes ecosystem. Here we report on the development of an indicator based on...Edsall, Thomas A.

Burrowing mayflies (Hexagenia) as indicators of ecosystem health at Sleeping Bear Dunes National Lakeshore, Michigan
The present study describes the provisional use of burrowing mayflies (Hexagenia [Ephemeroptera: Ephemeridae]) as an indicator organism to assess and monitor the health of the Loon Lake and lower Platte River ecosystem within Sleeping Bear Dunes National Lakeshore, Michigan.Edsall, Thomas A.; Phillips, William E.

Educating veterinarians for careers in free-ranging wildlife medicine and ecosystem health
In the last 10 years, the field of zoological medicine has seen an expansive broadening into the arenas of free-ranging wildlife, conservation medicine, and ecosystem health. During the spring/summer of 2005, we prepared and disseminated a survey designed to identify training and educational needs for individuals entering the wildlife medicine and...Mazet, J.A.K.; Hamilton, G.E.; Dierauf, L.A.
Integrating gene transcription-based biomarkers to understand desert tortoise and ecosystem health
Tortoises are susceptible to a wide variety of environmental stressors, and the influence of human disturbances on health and survival of tortoises is difficult to detect. As an addition to current diagnostic methods for desert tortoises, we have developed the first leukocyte gene transcription biomarker panel for the desert tortoise (Gopherus...Bowen, Lizabeth; Miles, A.

Environmental quality and preservation; reefs, corals, and carbonate sands; guides to reef-ecosystem health and environment
Introduction In recent years, the health of the entire coral reef ecosystem that lines the outer shelf off the Florida Keys has declined markedly. In particular, loss of those coral species that are the building blocks of solid reef framework has significant negative implications for economic vitality of the region. What are the reasons...Lidz, Barbara H.
Burrowing mayflies (Hexagenia) as indicators of aquatic ecosystem health at Sleeping Bear Dunes National Lakeshore, Michigan
With concern running high for the ecological effects of nutrient introductions in waters near the park, researchers document baseline conditions of aquatic park resources, applying a method that can be fine-tuned for future trend monitoring.Edsall, T.A.; Phillips, W.E.

Aquatic bird disease and mortality as an indicator of changing ecosystem health
We analyzed data from pathologic investigations in the United States, collected by the USGS National Wildlife Health Center between 1971 and 2005, into aquatic bird mortality events. A total of 3619 mortality events was documented for aquatic birds, involving at least 633 708 dead birds from 158 species belonging to 23 families. Environmental...Newman, S.H.; Chmura, A.; Converse, K.; Kilpatrick, A.M.; Patel, N.; Lammers, E.; Daszak, P.
Hematology of southern Beaufort Sea polar bears (2005-2007): Biomarker for an arctic ecosystem health sentinel
Declines in sea-ice habitats have resulted in declining stature, productivity, and survival of polar bears in some regions. With continuing sea-ice declines, negative population effects are projected to expand throughout the polar bear's range. Precise causes of diminished polar bear life history performance are unknown, however, climate and sea-...Kirk, Cassandra M.; Amstrup, Steven C.; Swor, Rhonda; Holcomb, Darce; O'Hara, T. M.
The use of tumors in wild populations of fish to assess ecosystem health
Evidence has linked toxicants in aquatic systems with cancer in fish and population level effects on species. Thus some types of tumors may be useful monitors of ecosystem health, at least as affected by genotoxins and promoters. However, tumors caused by purely genetic mechanisms or by virus would not be good indicators. Only neoplasms which have...Baumann, Paul C.
Urban development and stream ecosystem health—Science capabilities of the U.S. Geological Survey
Urban development creates multiple stressors that can degrade stream ecosystems by changing stream hydrology, water quality, and physical habitat. Contaminants, habitat destruction, and increasing streamflow variability resulting from urban development have been associated with the disruption of biological communities, particularly the loss of...Reilly, Pamela A.; Szabo, Zoltan; Coles, James F.
Burrowing mayflies as indicators of ecosystem health: Status of populations in two western Lake Superior embayments
The U.S. Environmental Protection Agency and Environment Canada are supporting the development of indicators of ecosystem health that can be used to report on progress in restoring and maintaining the Great Lakes ecosystem, as called for in the Great Lakes Water Quality Agreement between the United States and Canada. One indicator under...Edsall, Thomas A.; Gorman, Owen T.; Evrard, Lori M.

Manatees as sentinels of marine ecosystem health: are they the 2000-pound canaries?
The order Sirenia is represented by three species of manatees and one species of dugong distributed in tropical and subtropical regions of the world and considered vulnerable to extinction. The sentinel species concept is useful to identify indicators of the environment and may reflect the quality of health in marine ecosystems. The single species...Bonde, R.K.; Aguirre, A.A.; Powell, J.
African dust carries microbes across the ocean: are they affecting human and ecosystem health?
Atmospheric transport of dust from northwest Africa to the western Atlantic Ocean region may be responsible for a number of environmental hazards, including the demise of Caribbean corals; red tides; amphibian diseases; increased occurrence of asthma in humans; and oxygen depletion (eutrophication) in estuaries. Studies of satellite images suggest...Kellogg, Christina A.; Griffin, Dale W.
