Synthesis of studies in the fall low-salinity zone of the San Francisco Estuary, September-December 2011 Synthesis of studies in the fall low-salinity zone of the San Francisco Estuary, September-December 2011
In fall 2011, a large-scale investigation (fall low-salinity habitat investigation) was implemented by the Bureau of Reclamation in cooperation with the Interagency Ecological Program to explore hypotheses about the ecological role of low-salinity habitat in the San Francisco Estuary—specifically, hypotheses about the importance of fall low-salinity habitat to the biology of delta smelt...

Stream macroinvertebrate response models for bioassessment metrics: addressing the issue of spatial scale Stream macroinvertebrate response models for bioassessment metrics: addressing the issue of spatial scale
We developed independent predictive disturbance models for a full regional data set and four individual ecoregions (Full Region vs. Individual Ecoregion models) to evaluate effects of spatial scale on the assessment of human landscape modification, on predicted response of stream biota, and the effect of other possible confounding factors, such as watershed size and elevation, on model...

Enriquillo–Plantain Garden fault zone in Jamaica: paleoseismology and seismic hazard Enriquillo–Plantain Garden fault zone in Jamaica: paleoseismology and seismic hazard
The countries of Jamaica, Haiti, and the Dominican Republic all straddle the Enriquillo–Plantain Garden fault zone ( EPGFZ), a major left-lateral, strike-slip fault system bounding the Caribbean and North American plates. Past large earthquakes that destroyed the capital cities of Kingston, Jamaica (1692, 1907), and Port-au-Prince, Haiti (1751, 1770), as well as the 2010 Haiti earthquake...

Implications for future survival of delta smelt from four climate change scenarios for the Sacramento–San Joaquin Delta, California Implications for future survival of delta smelt from four climate change scenarios for the Sacramento–San Joaquin Delta, California
Changes in the position of the low salinity zone, a habitat suitability index, turbidity, and water temperature modeled from four 100-year scenarios of climate change were evaluated for possible effects on delta smelt Hypomesus transpacificus, which is endemic to the Sacramento–San Joaquin Delta. The persistence of delta smelt in much of its current habitat into the next century appears...

Effects of urban development on stream ecosystems in nine metropolitan study areas across the United States Effects of urban development on stream ecosystems in nine metropolitan study areas across the United States
Urban development is an important agent of environmental change in the United States. The urban footprint on the American landscape has expanded during a century and a half of almost continuous development. Eighty percent of Americans now live in metropolitan areas, and the advantages and challenges of living in these developed areas—convenience, congestion, employment, pollution—are...

Upper Clear Creek watershed aquatic chemistry and biota surveys, 2004-5, Whiskeytown National Recreation Area, Shasta County, California Upper Clear Creek watershed aquatic chemistry and biota surveys, 2004-5, Whiskeytown National Recreation Area, Shasta County, California
The U.S. Geological Survey, in cooperation with the National Park Service and Whiskeytown National Recreation Area, performed a comprehensive aquatic biota survey of the upper Clear Creek watershed, Shasta County, California, during 2004-5. Data collected in this study can provide resource managers with information regarding aquatic resources, watershed degradation, and regional...
