Study Description

Title:
Genetic Evaluation of the Great Basin Distinct Population Segment in Columbia Spotted Frogs (Rana luteiventris)

Status: Completed

Synopsis:
Columbia Spotted Frogs (CSF) are highly aquatic frogs native to the Great Basin, northern Rocky Mountains, British Columbia, and southeast Alaska. Populations of CSFs have declined in Oregon, Nevada, and Idaho due to habitat loss, introduced predators, and emerging infectious diseases. CSFs in these states are considered part of the Great Basin Distinct Population Segment (GB DPS), although this designation is not based on genetic delineation. Lack of genetic sampling efforts has lead to poor understanding of the geographical distribution of the GB DPS. USGS scientists are using genetic information to define the range of GB DPS CSFs. This work is critical for assessing the status of the GB DPS in a way field work cannot.
