Antibiotic use during the intracoelomic implantation of electronic tags into fish
D.M. Mulcahy
2011, Reviews in Fish Biology and Fisheries (21) 83-96
The use of antibiotics, in particular, the use of a single dose of antibiotics during electronic tag implantation is of unproven value, and carries with it the potential for the development of antibiotic resistance in bacteria and the alteration of the immune response of the fish. Antibiotic use during electronic...
Post-breeding bird responses to canopy tree retention, stand size, and edge in regenerating Appalachian hardwood stands
Molly E. McDermott, Petra B. Wood
2011, Forest Ecology and Management (262) 547-554
Avian use of even-aged timber harvests is likely affected by stand attributes such as size, amount of edge, and retained basal area, all characteristics that can easily be manipulated in timber harvesting plans. However, few studies have examined their effects during the post-breeding period. We studied the impacts of clearcut,...
Mechanism of the 1996-97 non-eruptive volcano-tectonic earthquake swarm at Iliamna Volcano, Alaska
Diana Roman, John A. Power
2011, Bulletin of Volcanology (73) 143-153
A significant number of volcano-tectonic (VT) earthquake swarms, some of which are accompanied by ground deformation and/or volcanic gas emissions, do not culminate in an eruption. These swarms are often thought to represent stalled intrusions of magma into the mid- or shallow-level crust. Real-time assessment of the likelihood that a...

Pigeonholing pyroclasts: Insights from the 19 March 2008 explosive eruption of Kīlauea volcano
Bruce F. Houghton, Don Swanson, R.J. Carey, J. Rausch, Andrew Sutton
2011, Geology (39) 263-266
We think, conventionally, of volcanic explosive eruptions as being triggered in one of two ways: by release and expansion of volatiles dissolved in the ejected magma (magmatic explosions) or by transfer of heat from magma into an external source of water (phreatic or phreatomagmatic explosions). We document here an event...
Magmatic-vapor expansion and the formation of high-sulfidation gold deposits: Structural controls on hydrothermal alteration and ore mineralization
Byron R. Berger, Richard W. Henley
2011, Ore Geology Reviews (39) 75-90
High-sulfidation copper–gold lode deposits such as Chinkuashih, Taiwan, Lepanto, Philippines, and Goldfield, Nevada, formed within 1500 m of the paleosurface in volcanic terranes. All underwent an early stage of extensive advanced argillic silica–alunite alteration followed by an abrupt change to spatially much more restricted stages of fracture-controlled sulfide–sulfosalt mineral assemblages...
