dc.description.abstractThe populations of many amphibian species appear to be in decline. The loss of amphibians contributes to the overall loss of biodiversity that is occurring on a global scale. Amphibians are well-known bioindicators and can perhaps aid in # pinpointing factors responsible for the loss of biodiversity. Habitat patch size is a crucial variable to species persistence. I examined the relationship between wetland area and population occupancy for three amphibian species of the Western Montana Rockies: Ambystoma macrodactylum (long-toed salamander), Bufo boreas (Western toad), and Rana luteiventris (spotted frog). A logistic regression analysis revealed significant associations between increasing wetland area and breeding activity for spotted frogs and long-toed salamanders. I observed a threshold wetland area required to sustain breeding populations, and suggest that this minimum area is essential for amphibian persistence. Although a significant association was not observed for Western toads, this absence was most likely due to small sample size.
