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.

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, non-nativAuthorsChristopher A. Pearl, M. J. Adams, N. Leuthold, R. Bruce BuryApparent 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 Jays, and mayAuthorsM.P. Murray, C.A. Pearl, R.B. BuryWetland management for amphibians in the Willamette Valley
Introduction In the past two decades, scientists around the world have increasingly noted losses of amphibian populations. Many of these declines have occurred in protected areas like national parks, where the causes mostly remain mysterious. However, in multipleuse landscapes, resource managers frequently face more obvious conservation problems and must make decisions that will affect amphibiaAuthorsM. J. Adams, Christopher A. Pearl, R. Bruce BuryAsymmetrical 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 invaded by R. caAuthorsC.A. Pearl, M.J. Adams, R.B. Bury, B. McCrearyWildfire, 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 across approxiAuthorsR. Bruce BuryOptical 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 species.

DiamondTerrestrial movements of juvenile and adult tailed frogs in relation to timber harvest in coastal British Columbia
Tailed frog (Ascaphus truei Stejneger) populations are at risk in much of the Pacific Northwest, and recolonization of sites may be slow postlogging. To examine the terrestrial movements of Ascaphus in clearcuts and old growth, we employed pitfall traps and drift-fence arrays installed along streams and 100 m into upland habitat. In the fall, we captured frogs farther from streams in old growth thAuthorsTanya R. Wahbe, Fred L. Bunnell, R. Bruce BuryDifferences in habitat use by blanding's turtles, Emydoidea blandingii, and painted turtles, Chysemys picta, in the Nebraska sandhills
We sampled a variety of wetlands in the Nebraska sandhills at Valentine National Wildlife Refuge. Significantly more individuals of painted turtles (Chrysemys picta) occurred in lakes and open waters than in marshes or small ponds, and the opposite was true for Blanding's turtles (Emydoidea blandingii). Besides this marked difference in habitat use, 46% of the captured E. blandingii in pond/marshAuthorsR. Bruce Bury, David J. GermanoOrganochlorine pesticides, PCBs, trace elements and metals in western pond turtle eggs from Oregon
With increased concern over the status of reptile populations globally, contaminant studies should be part of species evaluations. We analyzed eggs of western pond turtles from Fern Ridge Reservoir in western Oregon for 20 organochlorine (OC) pesticides or metabolites, 42 congener-specific polychlorinated biphenyls (PCBs), and 16 trace elements or metals. These eggs represent the first of this speAuthorsCharles J. Henny, K.F. Beal, R. Bruce Bury, R. GoggansFire and amphibians in North America
Information on amphibian responses to fire and fuel reduction practices is critically needed due to potential declines of species and the prevalence of new, more intensive fire management practices in North American forests. The goals of this review are to summarize the known and potential effects of fire and fuels management on amphibians and their aquatic habitats, and to identify information gaAuthorsD. S. Pilliod, R.B. Bury, E.J. Hyde, C.A. Pearl, P. S. CornIndirect facilitation of an anuran invasion by non-native fishes
Positive interactions among non-native species could greatly exacerbate the problem of invasions, but are poorly studied and our knowledge of their occurrence is mostly limited to plant-pollinator and dispersal interactions. We found that invasion of bullfrogs is facilitated by the presence of co-evolved non-native fish, which increase tadpole survival by reducing predatory macroinvertebrate densiAuthorsM. J.
