Mission Areas
Ecosystems
The USGS Ecosystems Mission Area, the biological research arm of the Department of the Interior (DOI), provides science to help America achieve sustainable management and conservation of its biological resources. This work is done within the broader mission of the USGS to serve the Nation with science that advances understanding of our natural resources and inform land and water stewardship.

Monitoring wetland water quality related to livestock grazing in amphibian habitats
Land use alteration such as livestock grazing can affect water quality in habitats of at-risk wildlife species. Data from managed wetlands are needed to understand levels of exposure for aquatic life stages and monitor grazing-related changes afield. We quantified spatial and temporal variation in water quality in wetlands occupied by threatened...
Smalling, Kelly; Rowe, Jennifer; Pearl, Christopher; Iwanowiczl, Luke R.; Givens, Carrie E.; Anderson, Chauncey W.; Mccreary, Brome; Adams, Michael J. Comparison of specimen and image-based morphometrics in Cisco
Morphometric data from fish are typically generated using one of two methods: from direct measurements made on a specimen, or by extracting distances from a digital picture. We compared data on twelve morphometrics collected with these two different methods on the same collection of Cisco Coregonus artedi to assess the degree of bias in...
O'Malley, Brian; Schmitt, Joseph; Holden, Jeremy P.; Weidel, Brian C. Historic population estimates for bottlenose dolphins (Tursiops truncatus) in Aragua, Venezuela indicate monitoring need
This study reports historic capture-mark-recapture survival and abundance estimates of common bottlenose dolphins (Tursiops truncatus) based on photo-identification surveys of coastal Venezuela (along the Aragua coast between Turiamo Bay and Puerto Colombia). We used the most recent data available: dolphins identified by unique dorsal fin marks...
