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.

Amphibian occurrence and aquatic invaders in a changing landscape: Implications for wetland mitigation in the Willamette Valley, Oregon Amphibian occurrence and aquatic invaders in a changing landscape: Implications for wetland mitigation in the Willamette Valley, Oregon
Despite concern about the conservation status of amphibians in western North America, few field studies have documented occurrence patterns of amphibians relative to potential stressors. We surveyed wetland fauna in Oregon's Willamette Valley and used an information theoretic approach (AIC) to rank the associations between native amphibian breeding occurrence and wetland characteristics...

Apparent predation by Gray Jays, Perisoreus canadensis, on Long-toed Salamanders, Ambystoma macrodactylum, in the Oregon Cascade Range Apparent predation by Gray Jays, Perisoreus canadensis, on Long-toed Salamanders, Ambystoma macrodactylum, in the Oregon Cascade Range
We report observations of Gray Jays (Perisoreus canadensis) appearing to consume larval Long-toed Salamanders (Ambystoma macrodactylum) in a drying subalpine pond in Oregon, USA. Corvids are known to prey upon a variety of anuran amphibians, but to our knowledge, this is the first report of predation by any corvid on aquatic salamanders. Long-toed Salamanders appear palatable to Gray...

Optical characteristics of natural waters protect amphibians from UV-B in the U.S. Pacific Northwest: Reply Optical characteristics of natural waters protect amphibians from UV-B in the U.S. Pacific Northwest: Reply
Few ecologists would dispute that exposure to high levels of ultraviolet-B radiation (UV-B) is detrimental to organisms. It is well established that UV-B has been a critical factor shaping the physiology (Blum et al. 1949, Hansson 2000), behavior (Pennington and Emlet 1986, van de Mortel and Buttemer 1998), and distribution (Williamson et al. 2001, Leavitt et al. 2003) of many aquatic...

Wildfire, fuels reduction, and herpetofaunas across diverse landscape mosaics in northwestern forests Wildfire, fuels reduction, and herpetofaunas across diverse landscape mosaics in northwestern forests
The herpetofauna (amphibians and reptiles) of northwestern forests (U.S.A.) is diverse, and many species are locally abundant. Most forest amphibians west of the Cascade Mountain crest are associated with cool, cascading streams or coarse woody material on the forest floor, which are characteristics of mature forests. Extensive loss and fragmentation of habitat resulted from logging...

Asymmetrical effects of introduced Bullfrogs (Rana catesbeiana) on native Ranid Frogs in Oregon Asymmetrical effects of introduced Bullfrogs (Rana catesbeiana) on native Ranid Frogs in Oregon
Introduced American Bullfrogs (Rana catesbeiana) have become widely established in the Pacific Northwest over the last century and are thought to be an important predator of native amphibians throughout the western United States. The Northern Red-Legged Frog (Rana aurora aurora) and Oregon Spotted Frog (Rana pretiosa) historically coexisted in portions of the Pacific Northwest now...
