In the summer of 2012, the lab is hosting Zachary Goeden as a participant of theHutton program of theAmerican Fisheries Society. Zach will be compiling an extensive dataset of well documented occurrencesof Thymallus arcticus (Arctic grayling) across Alaska and surrounding regions. In the lab, Zach will assemble a set of DNA sequences from samples representing Alaska's major freshwater regions (north, central and southern). The overall goal of the project is to establish to what extent physical and ecological barriers may shape the geographic distribution of genetic variability among populations of grayling in Alaska. Through the summer, Zach will document the project's progress and the lessons he learns in the process on his blog: graylinghutton.
