URAP students Bri Baumbach and Marc Bonnot have been working hard all semester on a project led by Max Lambert to quantify morphological differences across the range of the Cascades Frog (Rana cascadae). This species is undergoing review for listing under the United States Endangered Species Act. Bri and Marc will provide evidence for morphological differences among populations that will help in assessing whether Cascades Frog should become a listed species. The data will be merged with an ongoing genomic analysis by the Washington Department of Fish and Wildlife (led by Max) to determine whether there is any important genetic and anatomical differentiation among Cascades Frog populations.

As the semester winds down, we were able to set up a visit for URAP students Bri and Marc to visit the CAS Herpetology collection (thanks Lauren for hosting!) to measure more Rana cascadae specimens. Lauren made time to show us the irreplaceable Galapagos tortoise shell collection. We learned that the animals were collected in 1905, and that during the collection trip the CAS burned down in the SF earthquake. The tortoises were then the new foundation of the collection when they arrived. At the time of their collection, more than 15,000 tortoises were being killed annually for various reasons (many for meat or other animal products).
