R. Bruce Bury
I am a Scientist Emeritus at the USGS Forest and Rangeland Ecosystem Science Center. My research focuses on amphibians and reptiles.
My research interests include ecology of aquatic and forest ecosystems, conservation biology of amphibians and reptiles, the effects of perturbations on animal populations, biological invasions, and inventorying and monitoring.

Western pond turtles (Clemmys marmorata) in the central valley of California: Status and population structure Western pond turtles (Clemmys marmorata) in the central valley of California: Status and population structure
A sensitive resettable odometer reading to 0.01 mile facilitated censusing breeding male redwinged blackbirds (Agelaius phoeniceus) from a vehicle. Territorial males along roadsides were 'marked' with recorded mileage readings rather than with landmarks of the types employed by Hewitt for censuses based on the Lincoln index principle. Sensitive odometers that can be reset have many...

Response of hatchling and yearling turtles to thermal gradients: Comparison of Chelydra serpentina and Trachemys scripta Response of hatchling and yearling turtles to thermal gradients: Comparison of Chelydra serpentina and Trachemys scripta
In laboratory tests, young Chelydra serpentina and Trachemys scripta altered their distribution in the presence of a temperature gradient. Selection of temperatures in the gradient for hatchlings and yearlings showed that body temperatures (Tbs) of C. serpentina were lower than T. scripta, but the difference was insignificant. Relatively low Tbs could allow greater activity range and...

Klamath-Siskiyou herpetofauna: Biogeographic patterns and conservation strategies Klamath-Siskiyou herpetofauna: Biogeographic patterns and conservation strategies
The Klamath-Siskiyou region of southwest Oregon and northwest California (USA) has some of the most complex landscape mosaics and plant communities in western North America, reflecting its marked diversity of precipitation and topography. With 38 native species of amphibians and reptiles, the Klamath-Siskiyou region has the most species-rich herpetofauna of any similarly sized mountain...

Variation in age at metamorphosis across a latitudinal gradient for the tailed frog, Ascaphus truei Variation in age at metamorphosis across a latitudinal gradient for the tailed frog, Ascaphus truei
Tailed frogs (Ascaphus truei) occur in permanent, cold streams in northwestern North America. Their tadpoles reportedly undergo metamorphosis after 2-4 years. Coastal populations that we examined transformed in 2 yr from the Olympic peninsula in Washington to northern Oregon, but in 1 yr from central Oregon to northern California. One inland site in northern California had a 2-yr period...
