2005, Chemical Geology (215) 453-472
Prior to remediation at the abandoned Cu-Zn Penn Mine in the Foothills massive sulfide belt of the Sierra Nevada, CA, acid mine drainage (AMD) was created, in part, by the subaerial oxidation of sulfides exposed on several waste piles. To support remediation efforts, a mineralogical study of the waste piles...
An evaluation of weather and disease as causes of decline in two populations of boreal toads
Rick D. Scherer, Erin L. Muths, Barry R. Noon, Paul Stephen Corn
2005, Ecological Applications (15) 2150-2160
Two populations of boreal toads (Bufo boreas) experienced drastic declines in abundance in the late 1990s. Evidence supported the hypothesis of disease (the chytrid fungus, Batrachochytrium dendrobatidis) as the cause of these declines, but other hypotheses had not been evaluated. We used an 11-year capture–recapture data set to...

Selecting a distributional assumption for modelling relative densities of benthic macroinvertebrates
B. R. Gray
2005, Ecological Modelling (185) 1-12
The selection of a distributional assumption suitable for modelling macroinvertebrate density data is typically challenging. Macroinvertebrate data often exhibit substantially larger variances than expected under a standard count assumption, that of the Poisson distribution. Such overdispersion may derive from multiple sources, including heterogeneity of habitat (historically and spatially), differing life...
