Colonial nesting Yellow-crowned Night Herons on the San Antonio River Walk
Clint W. Boal
2010, Bulletin of the Texas Ornithological Society (43) 45-48
Yellow-crowned Night Herons (Nyctinassa violacea) typically nest as single pairs or in small colonies of about four pairs with high internest distances. They are also reported as susceptible to disturbance and to avoid habitat with high human use. However, some Yellowcrowned Night Herons habituate to human-dominated landscapes and nest in...

Hydrologic conditions in the Florida Panther National Wildlife Refuge, 2006-2007
Ronald S. Reese
2010, Open-File Report 2010-1270
Much of the surface water that flows into the Florida Panther National Wildlife Refuge (FPNWR) probably exits southward through Fakahatchee Strand as it did prior to development, because culverts and bridges constructed along I-75 allow overland flow to continue southward within the strand. During the dry season and periods of...

John E. Doherty, Randall J. Hunt
2010, Scientific Investigations Report 2010-5169
Highly parameterized groundwater models can create calibration difficulties. Regularized inversion-the combined use of large numbers of parameters with mathematical approaches for stable parameter estimation-is becoming a common approach to address these difficulties and enhance the transfer of information contained in field measurements to parameters used to model that system. Though...

Robert Peters, Bruce Jaffe
2010, Open-File Report 2010-1239
There is a need for a clear procedure to identify tsunami deposits in the geologic record. Data from published studies documenting recent tsunami deposits provide a means of developing identification criteria based on the sedimentary characteristics of unequivocal tsunami deposits. Recent tsunami deposits have many sedimentary characteristics in common. All...

The role of water in generating the calc-alkaline trend: New volatile data for aleutian magmas and a new tholeiitic index
Mindy M. Zimmer, Terry Plank, Erik H. Hauri, Gene Yogodzinski, Peter L. Stelling, Jessica Larsen, Brad Singer, Brian R. Jicha, Charlie Mandeville, Christopher J. Nye
2010, Journal of Petrology (51) 2411-2444
The origin of tholeiitic (TH) versus calc-alkaline (CA) magmatic trends has long been debated. Part of the problem stems from the lack of a quantitative measure for the way in which a magma evolves. Recognizing that the salient feature in many TH–CA discrimination diagrams is enrichment in Fe during magma...

The principal rare earth elements deposits of the United States: A summary of domestic deposits and a global perspective
Keith R. Long, Bradley S. Van Gosen, Nora K. Foley, Daniel Cordier
2010, Scientific Investigations Report 2010-5220
The rare earth elements (REE) are fifteen elements with atomic numbers 57 through 71, from lanthanum to lutetium ('lanthanides'), plus yttrium (39), which is chemically similar to the lanthanide elements and thus typically included with the rare earth elements. Although industrial demand for these elements is relatively small in tonnage...
