Calystegia stebbinsiiStebbin’s morning glory is historically rare in that it has always been restricted to three populations that occur in Nevada and El Dorado Counties. In this talk we will explain how genetic monitoring is used to understand population dynamics and genetic variation within this species. Generally speaking, high genetic variation is good because it allows species to respond to environmental change. In this presentation, we will discuss how genetic information is being used to guide management practices with the goal of maintaining high variation in populations of Calystegia stebbinsii. The presentation will be held on Tuesday evening, May 10, 2016, from 6:30–7:30 pm, at the Sierra College Nevada County Campus in the Multipurpose Center, building, N-12. Come early and enjoy a meet-and-greet and refreshments at 6:00 pm.

About our presenters:

Sandra Namoff is a PhD candidate at Rancho Santa Ana Botanic Garden and Claremont Graduate University located in southern California. She worked as a research technician studying palm biology and conservation genetics at Fairchild Tropical Botanic Garden after graduating from Florida International University with a B.S. Currently she is using molecular phylogenetic and population genetic methods to understand evolution and diversity in Calystegia, a genus in the morning glory family. Species delimitation and taxonomy within the genus have been difficult due to recent speciation, conserved morphology and putative hybridization. Coalescent methods will be used to estimate species relationships in the genus. Molecular methods will also be used to evaluate hybridization potential among taxa. Additionally, Calystegia is interesting because it contains both rare and weedy species. Genetic diversity related to species abundance will be investigated in a phylogenetic framework to inform conservation and invasive species management.

Denise Della Santina earned her B.S. in Conservation Biology at the University of Wisconsin-Madison. With the U.S. Fish and Wildlife Service, Denise monitored rare plants and animals around the S.F. Bay and Central Coast. She worked in natural resource management and designed and led habitat restoration projects at Yosemite, Lassen and Golden Gate National Parks. At Audubon Canyon Ranch in Marin County, she started a volunteer restoration and native plant propagation program. Denise grew over 30,000 plants a year as the native plant nursery manager for Save The Bay in S.F. She worked on riparian restoration projects along the Yuba River and Sacramento Delta and surveyed for rare plants throughout the Yuba and American River watersheds with the Tahoe National Forest. As the president of the Redbud Chapter of the California Native Plant Society, Denise has worked on native plant conservation projects throughout Nevada and Placer Counties, including the Stebbins morning glory project.

This presentation is free, and the public is welcome and encouraged to attend. The Nevada County Campus is located at 250 Sierra College Drive, Grass Valley, CA 95945. Parking is $3 on campus and permits can be purchased at the kiosk machine at the main entrance to the campus.
