Integrated Science: Florida Manatees and Everglades Hydrology
Catherine A. Langtimm, Eric D. Swain, Bradley Stith, James P. Reid, Daniel H. Slone, Jeremy Decker, Susan M. Butler, Terry Doyle, R.W. Snow
2009, Fact Sheet 2009-3002
Predicting and monitoring restoration effects on Florida manatees, which are known to make extended movements, will be incomplete if modeling and monitoring are limited to the smaller areas defined by the various res-toration components. U.S. Geological Survey (USGS) efforts, thus far, have focused on (1) collecting manatee movement data throughout...

Evaluation of the effects of precipitation on ground-water levels from wells in selected alluvial aquifers in Utah and Arizona, 1936-2005
Philip M. Gardner, Victor M. Heilweil
2009, Scientific Investigations Report 2008-5242
Increased withdrawals from alluvial aquifers of the southwestern United States during the last half-century have intensified the effects of drought on ground-water levels in valleys where withdrawal for irrigation is greatest. Furthermore, during wet periods, reduced withdrawals coupled with increased natural recharge cause rising ground-water levels. In order to manage...

Juliet C. Stromberg, Matthew K. Chew, Pamela L. Nagler, Edward P. Glenn
2009, Restoration Ecology (17) 177-186
Initially introduced to western United States to provide ecosystem services such as erosion control, Tamarix by the mid-1900s had became vilified as a profligate waster of water. This large shrub continues, today, to be indicted for various presumed environmental and economic costs, and millions of dollars are expended on its eradication. In...
Predator avoidance performance of larval fathead minnows (Pimephales promelas) following short-term exposure to estrogen mixtures
Meghan R. McGee, Matthew L. Julius, Alan M. Vajda, David O. Norris, Larry B. Barber, Heiko L. Schoenfuss
2009, Aquatic Toxicology (91) 355-361
Aquatic organisms exposed to endocrine disrupting compounds (EDCs) at early life-stages may have reduced reproductive fitness via disruption of reproductive and non-reproductive behavioral and physiological pathways. Survival to reproductive age relies upon optimal non-reproductive trait expression, such as adequate predator avoidance responses, which may be impacted through EDC exposure. During...
Persistence of dragonfly exuviae on vegetation and rock substrates
Maria A. Aliberti Lubertazzi, H. S. Ginsberg
2009, Northeastern Naturalist (16) 141-147
Surveys of dragonfly exuviae have been used to assess rare species' habitats, lake water quality status, and wetland restoration programs. Knowledge of the persistence of exuviae on various substrates is necessary to accurately interpret exuvial surveys. In 2006, we recorded exuvial persistence at defined areas in a variety of small...

Judith Z. Drexler, Christian S. de Fontaine, Steven J. Deverel
2009, Wetlands (29) 372-386
Throughout the world, many extensive wetlands, such as the Sacramento-San Joaquin Delta of California (hereafter, the Delta), have been drained for agriculture, resulting in land-surface subsidence of peat soils. The purpose of this project was to study the in situ effects of wetland drainage on the remaining peat in the...

2009, Southeastern Naturalist (8) 503-514
We compared the density and biomass of resident fish in vegetated and unvegetated flooded habitats of impounded salt marshes in the northern Indian River Lagoon (IRL) Estuary of east-central Florida. A 1-m2 throw trap was used to sample fish in randomly located, paired sample plots (n = 198 pairs) over 5...

Steven L. Markstrom, Lauren E. Hay
2009, Water Resources Impact (11) 8-10
As the questions of climate change has moved from “if” it is happening to “how” it is changing our environment, it has become important to have regional assessment designs to allow us to better understand how changes are occurring now and in the future. The authors are using the Precipitatation...
Mapping Hurricane Rita inland storm tide
Charles Berenbrock, Mason Jr., Stephen F. Blanchard
2009, Journal of Flood Risk Management (2) 76-82
Flood‐inundation data are most useful for decision makers when presented in the context of maps of affected communities and (or) areas. But because the data are scarce and rarely cover the full extent of the flooding, interpolation and extrapolation of the information are needed. Many geographic information systems provide various...

Joel A. Schmutz
2009, Open-File Report 2009-1040
Yellow-billed loons (Gavia adamsii) breed in low densities in northern tundra habitats in Alaska, Canada, and Russia. They migrate to coastal marine habitats at mid to high latitudes where they spend their winters. Harvest may occur throughout the annual cycle, but of particular concern are recent reports of harvest from...
