2015 Lab Retreat

We had our annual lab retreat to UW Friday Harbor Labs on San Juan Islands at the end of September. A few out of town visitors joined us for a “Biodiversity Genomics” workshop, including Dr. Matt Fujita (University of Texas, Arlington), Dr. Caleb Ofori-Boateng (Forestry Research Institute of Ghana), and Dan Portik (University of California, Berkeley). The four undergraduate summer interns  presented their research results on the phylogeography of various reptiles and amphibians in West and Central Africa.

Everything is Not Lost

Congratulations to Itzue on her new paper in the journal Mesoamerican Herpetology, “Everything is not lost: recent records, rediscoveries, and range extensions of Mexican hylid frogs“. The paper summarizes fieldwork results from the Mexican highlands. One significant finding is the rediscovery of five frog species that were considered possibly extinct in the wild. In addition, five new populations were discovered that expand the restricted distributions of three microendemic and one endemic species.frogs

Clay Toads

Matt McElroy published his research on toad coloration. He studied disruptive coloration in toads (Rhinella alata) on Barro Colorado Island in Panama using clay models (see figure below). Matt determined that the highly polymorphic colors and color patterns of Rhinella toads are functionally cryptic. What’s the consequence for the toads? Lower predation rates by birds.

Our collaborator from the Czech Republic, Dr. Václav Gvoždík (a.k.a. Vasek) from the Institute of Vertebrate Biology at the Czech Academy of Sciences is currently visiting the lab to collect SNP data for a new African frog phylogeography project. The project is focused on phylogeography of the “golden puddle frog” from across Central Africa. We have nearly 150 samples to work with of this wide-ranging species, which spans many of the significant riverine barriers in the Congo Forest. Vasek has studied a number of African frogs from East, West, and Central Africa using genetic methods, and he has also done work on tree frogs from across Europe. His main research interests are evolution, speciation and phylogenetic diversification of vertebrates using molecular-genetic approaches, and analyses of phenotype and biogeographic applications. You can read more about Vasek and his research at his website, including his current project focused on Amphibian diversification across sky-island and lowland rain forests in Africa.

Titanoboa: Monster Snake

titanoboa

Titanoboa is at the Burke Museum!

The exhibit includes a full-size replica of the giant snake, plus fossils, photos and videos that reconstruct Earth’s earliest-known rainforest and the lost world of life in the Paleocene following the demise of dinosaurs. We also have exhibit space devoted to snakes of Washington, Leonard’s research on Thamnophis population genetics on the San Juan Islands, and we are actively tanning snake skins in the exhibit. You can even watch the snake skin tanning process on a live webcam.
