Population dynamics of the Columbia spotted frog (Rana luteiventris): inference from long-term demography
… dynamics of a high elevation population of the Columbia spotted frog (Rana luteiventris) in relation to climate variation over a ten-year period.</p> <p>I documented an increase in survival and breeding probability as severity of winter decreased. Therefore, a warming climate with less severe …

Interactive effects of wildfire and disturbance history on amphibians and their parasites
… salamander (Ambystoma macrodactylum) and Columbia spotted frog (Rana luteiventris) were resistant to change during the first 6 years after wildfire, but declined over longer time periods in areas of high-severity fire. In contrast, boreal toad (Anaxyrus boreas) occupancy increased greatly …

The role of the skin microbiome in amphibian pathogen susceptibility in Turnbull National Wildlife Refuge
… examined in this region. We hypothesized that frogs with lower Bd infection intensities would have higher skin bacterial diversity and more abundant anti-Bd bacteria, indicative of a more protective function. Our study combined cultureindependent and culture-dependent methods to assess the …

Bioassessment and the Partitioning of Community Composition and Diversity Across Spatial Scales in Wetlands of the Bonneville Basin
… the least chub, Iotichthys phlegethontis and the Columbia spotted frog, Rana luteioventris, depend on these wetlands for their continued existence, many of which are already imperiled. The continued decline and loss of these wetlands would further push many of these species toward endangerment …
