Stream-Water Temperature Limits Occupancy of Salamanders in Mid-Atlantic Protected Areas
Abstract Stream ecosystems are particularly sensitive to urbanization, and tolerance of water-quality parameters is likely important to population persistence of stream salamanders. ForecastedExpand

Regional variation in radionuclide concentrations and radiation dose in caribou (Rangifer tarandus) in the Canadian Arctic; 1992-94.
Gamma-emitting radionuclides and 210Po, an alpha-emitting product of the 238U decay chain, were analysed in tissues from 16 caribou (Rangifer tarandus) collections in the Canadian North between 1992Expand

Bioconcentration of fallout 137Cs by fungi and red-backed voles (Clethrionomys gapperi).
Cesium-137 and 40K concentrations were measured in vegetation and in red-backed voles (Clethrionomys gapperi) in southeastern Manitoba, Canada, following the Chernobyl accident in 1986. Voles fromExpand

Breeding-season biology of the Puerto Rican Bullfinch ( Loxigilla portoricensis)
I studied the Puerto Rican Bullfinch (Loxigilla portoricensis), a frugivorous island endemic, in two sites in southwestern Puerto Rico in 2009 and 2010. I modeled nest survival of 37 nests to betterExpand

ESTIMATING OCCURRENCE, PREVALENCE, AND DETECTION OF AMPHIBIAN PATHOGENS: INSIGHTS FROM OCCUPANCY MODELS.
Understanding the distribution of pathogens across landscapes and their prevalence within host populations is a common aim of wildlife managers. Despite the need for unbiased estimates of pathogenExpand

Proactive management of amphibians: Challenges and opportunities
Abstract Delaying species management reduces the chance of successful recovery, increases the risk of extinction, and can be expensive. Acting before major declines are realized affords access to aExpand

Improving our understanding of demographic monitoring: avian breeding productivity in a tropical dry forest
The ratio of juvenile to adult birds in mist‐net samples is used to monitor avian productivity, but whether it is a “true” estimate of per capita productivity or an index proportional to productivityExpand
