Along with other conifers of the Sierra Nevada, giant sequoia is threatened by climate change related mortality. This can have devastating effects in some of the groves that are limited in size. This particularly true of northern isolated groves. Population isolation can lead to elevated levels of inbreeding that could be detrimental to their health and success under climate change. In this study, we will be attempting to determine levels and causes of genetic diversity in different sized groves of giant sequoia. We have collected seed from a number of groves in the northern and southern range of the species and have already shown signficant variation in the size of genetic demes that will likely influence the long-term success of groves. We are extending these analyses to include more groves and to better understand landscape processes that affect deme sizes.
Spur student will assist in a gene diversity and gene-flow study of Sequoiadendron giganteum (giant sequoia). This research work will provide student with extensive laboratory experience and training. Specifically, students will develop skills in seed germination, DNA extraction, DNA amplification, data collection, and data analysis. In addition, spur student will have the opportunity to conduct field collections of giant sequoia.
The undergraduate should have taken coursework in biochemistry and molecular biology. Should be willing to do field work as well as laboratory work.
