Late-season Reproduction in Western Toads (Bufo boreas)

Instream Movements by Boreal Toads (Bufo boreas boreas)

27 Twitty 1940; Nussbaum 1969). Our observations suggest that hyporheic zones might provide important and not previously recognized habitats for amphibians in intermittent headwater streams. Additional sampling is needed to better characterize hyporheic use by Dicamptodon and other stream amphibians such as the torrent salamanders (Rhyacotriton spp.). Better information notwithstanding, managem...

Ambient Levels of Ultraviolet-B Radiation Cause Mortality in Juvenile Western Toads, Bufo boreas

—Numerous anthropogenic and natural factors affect living organisms in nature. Anthropogenic factors include a wide array of contaminants and processes that alter the habitat on both local and global scales. For example, chlorofluorocarbons (CFCs) and other industrial gases contribute to the depletion of the earth’s protective ozone layer, resulting in increased amounts of cell damaging ultravi...

Juvenile western toads, Bufo boreas, avoid chemical cues of snakes fed juvenile, but not larval, conspecifics.

Previous investigations have demonstrated the importance of predator diet in chemically mediated antipredator behaviour. However, there are few data on responses to life-stage-specific predator diets, which could be important for animals like amphibians that undergo metamorphosis and must respond to different suites of predators at different life-history stages. In laboratory choice tests, we i...
