Temporal variation of hydrological exchange and hyporheic biogeochemistry in a headwater stream during autumn

Creator:: Argerich, Alba, Marti, Eugenia, Sabater, Francesc, and Ribot, Miquel
Abstract:: The hyporheic zone is of great interest for stream ecologists because of its role in stream biogeochemical processing. Our study addresses the effects of leaf-litter inputs and varying discharge on surface–hyporheic water exchange and their possible consequences for the hyporheic zone biogeochemistry. Our study was conducted during autumn in Riera...

Nonlinear ⁴⁰Ar/³⁹Ar age systematics along the Gilbert Ridge and Tokelau Seamount Trail and the timing of the Hawaii-Emperor Bend

Creator:: Koppers. Anthony A. P., Staudigel, Hubert, Morgan, Jason Phipps, and Dunca, Robert A.
Abstract:: Over the last three decades the first-order correlation in morphology and orientation of seamount trails has been called upon to support the concept of a ‘‘fixed’’ Pacific hot spot frame of reference and to explain the Hawaii-Emperor bend (HEB) by a dramatic change in Pacific plate motion. In this paper,...

Displacement transfer from fault-bend to fault-propagation fold geometry: An example from the Himalayan thrust front

Creator:: Qayyum, Mazhar, Spratt, Deborah A., Dixon, John M., and Lawrence, Robert D.
Abstract:: The leading edge of the ENE-trending Himalayan thrust front in Pakistan exhibits along-strike changes in deformational style, ranging from fault-bend to fault-propagation folds. Although the structural geometry is very gently deformed throughout the Salt Range, it becomes progressively more complex to the east as the leading edge of the emergent...

Trends in Caspian Tern Nesting and Diet in San Francisco Bay: Conservation Implications for Terns and Salmonids

Creator:: Collis, Ken, Roby, Daniel D., Larson, Keith W., Adrean, Lindsay J., Nelson, S. Kim, Evans, Allen F., Hostetter, Nathan, Battaglia, Dan, Lyons, Donald E., Marcella, Tim, and Patterson, Allison
Abstract:: Colony size, nesting ecology and diet of Caspian Terns (Hydroprogne caspia) were investigated in the San Francisco Bay area (SFBA) during 2003-2009 to assess the potential for conservation of the tern breeding population and possible negative effects of predation on survival of juvenile salmonids (Oncorhynchus spp.). Numbers of breeding Caspian...

Process-Based Modeling to Assess the Effects of Recent Climatic Variation on Site Productivity and Forest Function across Western North America

Creator:: Waring, Richard H., Coops, Nicholas C., Mathys, Amanda, Hilker, Thomas, and Latta, Greg
Abstract:: A process-based forest growth model, 3-PG (Physiological Principles Predicting Growth), parameterized with values of soil properties constrained by satellite-derived estimates of maximum leaf area index (LAI[subscript max]), was run for Douglas-fir (Pseudotsuga menziesii) to contrast the extent to which site growth potential might vary across western North America between a...

Age-specific variation in apparent survival rates of male lesser-prairie-chickens

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Robel, Robert J., and Applegate, Roger D.
Abstract:: We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival...

Active dispersal in loggerhead sea turtles (Caretta caretta) during the ‘lost years’

Creator:: Briscoe, D. K., Parker, D. M., Balazs, G. H., Kurita, M., Saito, T., Okamoto, H., Rice, M., Polovina, J. J., and Crowder, L. B.
Abstract:: Highly migratory marine species can travel long distances and across entire ocean basins to reach foraging and breeding grounds, yet gaps persist in our knowledge of oceanic dispersal and habitat use. This is especially true for sea turtles, whose complex life history and lengthy pelagic stage present unique conservation challenges....

A Real-Time PCR Assay for Early Detection of Eastern Filbert Blight

Creator:: Molnar, Thomas J., Walsh, Emily, Capik, John M., Sathuvalli, Vidyasagar, Mehlenbacher, Shawn A., Rossman, Amy Y., and Zhang, Ning
Abstract:: Eastern filbert blight (EFB) is a devastating disease of European hazelnut, Corylus avellana, which causes economic losses in Oregon, where 99% of the U.S. crop is produced. The causal fungus, Anisogramma anomala, is native to eastern North America, where it is found associated with the American hazelnut (C. americana). Although...

Acoustic radiation from the head of echolocating harbor porpoises

Creator:: Au, Whitlow W. L., Kastelein, Ronald A., Benoit-Bird, Kelly J., Cranford, Ted W., and McKenna, Megan F.
Abstract:: An experiment was conducted to investigate the sound pressure patterns on the melon of odontocetes by using four broadband hydrophones embedded in suction cups to measure echolocation signals on the surface of the forehead of two harbor porpoises (Phocoena phocoena). It has long been hypothesized that the special lipids found...

Lidar-derived canopy architecture predicts brown creeper occupancy of two western coniferous forests

Creator:: Vogeler, Jody C., Hudak, Andrew T., Vierling, Lee A., and Vierling, Kerri T.
Abstract:: In western conifer-dominated forests where the abundance of old-growth stands is decreasing, species such as the Brown Creeper (Certhia americana) may be useful as indicator species for monitoring the health of old-growth systems because they are strongly associated with habitat characteristics associated with old growth and are especially sensitive to...
