Estimating Migration Rates Between Populations Of Zostera Marina In The San Francisco Bay, Elizabeth S. Gutierrez
Estimating Migration Rates Between Populations Of Zostera Marina In The San Francisco Bay, Elizabeth S. Gutierrez
STAR Program Research Presentations
Eelgrass (Zostera marina) is a highly clonal marine angiosperm that can also reproduce sexually through flowering and seed formation. In a previous study, Fst values from six microsatellite loci suggested that a perennial San Francisco Bay subpopulation at Point Molate (Richmond, California) was able to recover from a drastic 2006 die-off through seed recruitment from neighboring eelgrass subpopulations, changing its reproductive strategy from clonal to sexual. Although Fst measures continue to be widely used in population genetics, the assumptions under which they operate are not always appropriate given certain circumstances, such small population sizes and/or asymmetrical migration rates. Our summer …

Mammalian cells are known to express genes that are associated with repairing damaged DNA. The transcript CDKN1A is one of several cell cycle regulator genes expressed in response to cell damage by ionizing radiation (IR). In this study, male and female lymphocytes; previously exposed ex vivo to IR, were used to demonstrate linear gene expression responses that may vary between genders. We used qRT-PCR to generate response curves for CDKN1A. No differences were identified for the endogenous control gene GAPDH. CDKN1A expression demonstrated average fold changes well above three fold for three of the four healthy patient donors at 24 …
