E.S. Long, Duane R. Diefenbach, C.S. Rosenberry, B.D. Wallingford, M.D. Grund
2005, Journal of Mammalogy (86) 623-629
Animal dispersal patterns influence gene flow, disease spread, population dynamics, spread of invasive species, and establishment of rare or endangered species. Although differences in dispersal distances among taxa have been reported, few studies have described plasticity of dispersal distance among populations of a single species. In 2002-2003, we radiomarked 308...

S.J. Oyler-McCance, J. St. John, S.E. Taylor, A.D. Apa, T.W. Quinn
2005, Journal of Wildlife Management (69) 630-637
The newly described Gunnison sage-grouse (Centrocercus minimus) is a species of concern for management because of marked declines in distribution and abundance due to the loss and fragmentation of sagebrush habitat. This has caused remaining populations to be unusually small and isolated. We utilized mitochondrial DNA sequence data and data...

An autonomous, electromagnetic seepage meter to study coastal groundwater/surface-water exchange
Peter W. Swarzenski, Matt Charette, Christian D. Langevin
2004, Open-File Report 2004-1369
The bi-directional exchange of groundwater with coastal surface waters may influence not only coastal-water and geochemical budgets, but may also impact and direct coastal ecosystem change. For example, the widespread discharge of nutrient-enriched submarine groundwater into an estuary or lagoon may contribute directly to the onset and duration of eutrophication,...
