Abstract
Relationships between changing environmental variables and amphibian populations have been understudied. Yet, alterations to temperature and precipitation have been suggested as contributors to the decline of some pond-breeding species, such as the Oregon Spotted Frog (Rana pretiosa). R. pretiosa has been classified as the most endangered amphibian within Canada, yet the cause for its decline is unknown. Therefore, this paper examined associations between temperature and precipitation and R. pretiosa population trends using a 10-year data set from two breeding populations in the Lower Mainland of British Columbia. Timing of oviposition was positively related to higher temperature and increased precipitation within both populations (p
