Marc A. Chalupnicki, James H. Johnson, James E. McKenna Jr., Dawn E. Dittman
2010, North American Journal of Fisheries Management (30) 170-178
Walleyes Sander vitreus are stocked into Owasco Lake, New York, to provide a sport fishery, but the population must be sustained by annual hatchery supplementation despite the presence of appropriate habitat. Therefore, we evaluated walleye spawning success in Dutch Hollow Brook, a tributary of Owasco Lake, to determine whether early...

Longitudinal structure in temperate stream fish communities: evaluating conceptual models with temporal data
James H. Roberts, Nathaniel P. Hitt
2010, Conference Paper, Community ecology of stream fishes : concepts, approaches, and techniques; American Fisheries Symposium 73
Five conceptual models of longitudinal fish community organization in streams were examined: (1) niche diversity model (NDM), (2) stream continuum model (SCM), (3) immigrant accessibility model (IAM), (4) environmental stability model (ESM), and (5) adventitious stream model (ASM). We used differences among models in their predictions about temporal species turnover,...

Diel behavior of rearing fall Chinook salmon
Kenneth F. Tiffan, Tobias J. Kock, Joseph J. Skalicky
2010, Northwestern Naturalist (91) 342-345
In fisheries science, habitat use is often inferred when fish are sampled or observed in a particular location. Physical habitat is typically measured where fish are found, and thus deemed important to habitat use. Although less common, a more informative approach is to measure or observe fish behavior within given...

Sheryl Tembe, David A. Lockner, Teng-Fong Wong
2010, Journal of Geophysical Research B: Solid Earth (115)
We investigated the frictional sliding behavior of simulated quartz-clay gouges under stress conditions relevant to seismogenic depths. Conventional triaxial compression tests were conducted at 40 MPa effective normal stress on saturated saw cut samples containing binary and ternary mixtures of quartz, montmorillonite, and illite. In all cases, frictional strengths of...

Improving inferences from fisheries capture-recapture studies through remote detection of PIT tags
David A. Hewitt, Eric C. Janney, Brian S. Hayes, Rip S. Shively
2010, Fisheries (35) 217-231
Models for capture-recapture data are commonly used in analyses of the dynamics of fish and wildlife populations, especially for estimating vital parameters such as survival. Capture-recapture methods provide more reliable inferences than other methods commonly used in fisheries studies. However, for rare or elusive fish species, parameter estimation is often...

Current challenges using models to forecast seawater intrusion: lessons from the Eastern Shore of Virginia, USA
Ward E. Sanford, Jason P. Pope
2010, Hydrogeology Journal (18) 73-93
A three-dimensional model of the aquifer system of the Eastern Shore of Virginia, USA was calibrated to reproduce historical water levels and forecast the potential for saltwater intrusion. Future scenarios were simulated with two pumping schemes to predict potential areas of saltwater intrusion. Simulations suggest that only a few wells...

Gregory R. Jacobs, Charles P. Madenjian, David B. Bunnell, Jeffrey D. Holuszko
2010, Journal of Great Lakes Research (36) 312-317
We used analyses of burbot (Lota lota) and lake trout (Salvelinus namaycush) diets taken during spring gill-net surveys in northern Lake Michigan in 2006-2008 to investigate the potential for competition and predator-prey interactions between these two species. We also compared our results to historical data from 1932. During 2006-2008, lake...
