During 1998-2005, the U.S....
Modeling the human invader in the United States
Thomas J. Stohlgren, Catherine S. Jarnevich, Chandra P. Giri
2010, Journal of Applied Remote Sensing (4)
Modern biogeographers recognize that humans are seen as constituents of ecosystems, drivers of significant change, and perhaps, the most invasive species on earth. We found it instructive to model humans as invasive organisms with the same environmental factors. We present a preliminary model of the spread of modern humans in...

2010, Conference Paper, Proceedings of the 23rd Annual Symposium on the Application of Gephysics to Engrineering and Envrionmental Problems (SAGEEP)
Characterization of the hyporheic zone is of critical importance for understanding stream ecology, contaminant transport, and groundwater‐surface water interaction. A salt water tracer test was used to probe the hyporheic zone of a recently re‐engineered portion of Crabby Creek, a stream located near Philadelphia, PA. The tracer solution was tracked...
Rheologic and structural controls on the deformation of Okmok volcano, Alaska: FEMs, InSAR, and ambient noise tomography
Timothy Masterlark, Matthew M. Haney, Haylee Dickinson, Cheryl Searcy, T. Fournier
2010, Journal of Geophysical Research B: Solid Earth (115)
Interferometric synthetic aperture radar (InSAR) data indicate that the caldera of Okmok volcano, Alaska, subsided more than a meter during its eruption in 1997. The large deformation suggests a relatively shallow magma reservoir beneath Okmok. Seismic tomography using ambient ocean noise reveals two low‐velocity zones (LVZs). The shallow LVZ corresponds...

John W. Fulton, Chad R. Wagner, Megan E. Rogers, Gregory F. Zimmerman
2010, Ecological Modelling (221) 540-554
The Allegheny River in Pennsylvania supports a large and diverse freshwater-mussel community, including two federally listed endangered species, Pleurobema clava(Clubshell) and Epioblasma torulosa rangiana (Northern Riffleshell). It is recognized that river hydraulics and morphology play important roles in mussel distribution. To assess the hydraulic influences of bridge replacement on mussel habitat, metrics...
