Zoogeography, conservation, and ecology of crayfishes within the Cheat River basin of the Upper Monongehela River drainage, West Virginia
Stuart A. Welsh
2009, Proceedings of the West Virginia Academy of Science (81) 25-40
During summer 2008, we studied the geographic distribution and conservation status of crayfishes within the Cheat River basin of the upper Monongahela River drainage. Stream sites (n = 73) were selected with a probabilistic sampling design, whereas one reservoir (Cheat Lake) and seven terrestrial sites for burrowing crayfishes were selected...

We studied the distribution of Pasteurella trehalosi genotypes isolated from oropharyngeal tissues of Rocky Mountain bighorn sheep (Ovis canadensis canadensis) in Waterton Lakes National Park, Alberta, Canada and Glacier National Park, Montana, USA. A separate radio-telemetry study indicated the bighorn metapopulation consisted of at least three neighborhoods of multiple ewe...
Population dynamics of long-tailed ducks breeding on the Yukon-Kuskokwim Delta, Alaska
Jason L. Schamber, Paul L. Flint, J. Barry Grand, Heather M. Wilson, Julie A. Morse
2009, Arctic (62) 190-200
Population estimates for long-tailed ducks in North America have declined by nearly 50% over the past 30 years. Life history and population dynamics of this species are difficult to ascertain, because the birds nest at low densities across a broad range of habitat types. Between 1991 and 2004, we collected...

Extending nearly 400 km from Sabine Pass on the Texas-Louisiana border east to the Chandeleur Islands, the Louisiana coastal zone (Fig. 11.1) along the north-central Gulf of Mexico is the southern terminus of the largest drainage basin in North America (>3.3 million km2), which includes the Mississippi River delta plain...
Constraints on the stress state of the San Andreas fault with analysis based on core and cuttings from SAFOD drilling phases 1 and 2
Cheryl Tembe, David A. Lockner, Teng-fong Wong
2009, Journal of Geophysical Research - Solid Earth (114)
Analysis of field data has led different investigators to conclude that the San Andreas Fault (SAF) has either anomalously low frictional sliding strength (μ < 0.2) or strength consistent with standard laboratory tests (μ > 0.6). Arguments for the apparent weakness of the SAF generally hinge on conceptual models involving intrinsically weak...
Methane sources and production in the northern Cascadia margin gas hydrate system
John W. Pohlman, Masanori Kaneko, Verena B. Heuer, Richard B. Coffin, Michael Whiticar
2009, Earth and Planetary Science Letters (287) 504-512
The oceanographic and tectonic conditions of accretionary margins are well-suited for several potential processes governing methane generation, storage and release. To identify the relevant methane evolution pathways in the northern Cascadia accretionary margin, a four-site transect was drilled during Integrated Ocean Drilling Program Expedition 311. The δ13C values of methane...
Hydrodynamic control of phytoplankton loss to the benthos in an estuarine environment

2009, Limnology and Oceanography (54) 952-969
Field experiments were undertaken to measure the influence of hydrodynamics on the removal of phytoplankton by benthic grazers in Suisun Slough, North San Francisco Bay. Chlorophyll a concentration boundary layers were found over beds inhabited by the active suspension feeders Corbula amurensis and Corophium alienense and the passive suspension feeders...

Methane gas hydrates, crystalline inclusion compounds formed from methane and water, are found in marine continental margin and permafrost sediments worldwide. This article reviews the current understanding of phenomena involved in gas hydrate formation and the physical properties of hydrate‐bearing sediments. Formation phenomena include pore‐scale habit, solubility, spatial variability, and...

2009, Fire in the Ice: NETL Methane Hydrate Newsletter (9) 6-9
The potential interactions between climate change and methane hydrate destabilization are among the most societally-relevant aspects of gas hydrates research. Massive dissociation of deep marine methane hydrates following rapid Earth warming is the most plausible explanation for carbon isotopic data that imply widespread release of microbial methane during the Late...

L. David Mech, H. Dean Cluff
2009, Canadian Field-Naturalist (123) 68-69
Wolves, Canis lupus, on Ellesmere Island traveled a daily round-trip distance of 40.2 km from their den to a landfill during July 2008, plus an undetermined distance hunting after leaving the landfill. Although long travels by Wolves are well known, this appears to be the first documentation of long daily...

Kevin A. Haas, John C. Warner
2009, Ocean Modelling (26) 91-103
Predictions of nearshore and surf zone processes are important for determining coastal circulation, impacts of storms, navigation, and recreational safety. Numerical modeling of these systems facilitates advancements in our understanding of coastal changes and can provide predictive capabilities for resource managers. There exists many nearshore coastal circulation models, however they...

Harvey E. Belkin, R. MacDonald, F. Wall, B. Baginski
2009, Mineralogical Magazine (73) 777-796
Electron microprobe analyses are presented of chevkinite-group minerals from Canada, USA, Guatemala, Norway, Scotland, Italy and India. The host rocks are metacarbonates, alkaline and subalkaline granitoids, quartz-bearing pegmatites, carbonatite and an inferred K-rich tuff. The analyses extend slightly the range of compositions in the chevkinite group, e.g. the most...

Kathleen M. Longshore, Chris E. Lowrey, Matthew Jeffress, Daniel B. Thompson
2009, Desert Bighorn Council Transactions (50) 18-31
Adequate management of a species requires complete knowledge of its ecology, including both nocturnal and diurnal behavior. Knowledge of the movement behavior of bighorn sheep can provide insight for understanding spatial population processes as the combined result of individual behavior, physiological constraints, and fine-scale environmental influences. However, because of past...
