Matthew S. Recsetar, Scott A. Bonar, Olin Feuerbacher
2014, Transactions of the American Fisheries Society (143) 1247-1254
Increasing stream temperatures have important implications for arid-region fishes. Little is known about effects of high water temperatures that fluctuate over extended periods on Apache Trout Oncorhynchus gilae apache, a federally threatened species of southwestern USA streams. We compared survival and growth of juvenile Apache Trout held for 30 d in...
Lateritic, supergene rare earth element (REE) deposits
Mark D. Cocker
2014, Conference Paper, Arizona Geological Survey Special Paper 9
Intensive lateritic weathering of bedrock under tropical or sub-tropical climatic conditions can form a variety of secondary, supergene-type deposits. These secondary deposits may range in composition from aluminous bauxites to iron and niobium, and include rare earth elements (REE). Over 250 lateritic deposits of REE are currently known and many...

Micro-seismicity and seismic moment release within the Coso Geothermal Field, California
J. Ole Kaven, Stephen H. Hickman, Nicholas C. Davatzes
2014, Conference Paper, Proceedings, Thirty-Ninth Workshop on Geothermal Reservoir Engineering
We relocate 16 years of seismicity in the Coso Geothermal Field (CGF) using differential travel times and simultaneously invert for seismic velocities to improve our knowledge of the subsurface geologic and hydrologic structure. We expand on our previous results by doubling the number of relocated events from April 1996 through...

Qiang Yang, Charles W. Culbertson, Martha G. Nielsen, Charles W. Schalk, Carole D. Johnson, Robert G. Marvinney, Martin Stute, Yan Zheng
2014, Science of the Total Environment (505) 1291-1307
To understand the hydrogeochemical processes regulating well water arsenic (As) evolution in fractured bedrock aquifers, three domestic wells with [As] up to 478 μg/L are investigated in central Maine. Geophysical logging reveals that fractures near the borehole bottom contribute 70-100% of flow. Borehole and fracture water samples from various depths...

Charles R. Bacon, Christina A. Neal, Thomas P. Miller, Robert G. McGimsey, Christopher J. Nye
2014, Professional Paper 1810
Aniakchak is a Pleistocene to Holocene composite volcano of the Alaska–Aleutian arc that suffered at least one caldera-forming eruption in postglacial time and last erupted in 1931. The oldest recognized postglacial eruption, Aniakchak I, produced andesite ignimbrite ca. 9,500–7,500 14C yr B.P. Subsequently, a vent northeast of the summit issued dacite–rhyodacite magma...

Why bother about wildlife disease?
Milton Friend
2014, Circular 1401
In most developed countries, the maintenance of the numbers of wildlife1 is vested in the natural resource agencies of those countries. During earlier times, game species were the primary focus of natural resource agencies2,3 however, current wildlife conservation continues to transition towards a more holistic focus on biodiversity4 and environmental health5,6. Nevertheless, that...
