Sedgwick Reserve

30 Jun, 05 PM - 29 Jun, 05 PM

Hybridization between plants native to restoration sites and individuals from distant populations may cause reduced vigor in subsequent generations due to ?hybrid breakdown? - the loss of locally adapted gene combinations through the process of genetic recombination. We propose to examine the genetic consequences of recent introductions of California native grass seeds from distant populations to Sedgwick Reserve of the U.C. Natural Reserve System. In this study, we will continue work to track gene flow between introduced and local grasses at Sedgwick and also reciprocal transplant experiments of three grass species between Sedgwick Reserve and Vandenberg Air Force Base. Thus far, we have found evidence of local adaptation in 2 out of 3 of the species and the investigation of the third species (Nassella pulchra) is underway.
