Conservation genetics of the endangered Apalachicola Rosemary, Conradina glabra.

Lauren Eserman, Atlanta Botanical Garden Conradina glabra, or Apalachicola rosemary, is a federally listed endangered species that exists only on a small area of sandhill in Liberty County, Florida. Forestry practices in the last 100 years have resulted in declining populations of C. glabra. In the wild, plants produce very few seeds, but small plants that resemble seedlings […]

Range-wide Ex Situ Seed Conservation and Population Genetic Architecture Analysis in Venus Flytrap (Dionaea muscipula)

Dr. Johnny Randall, North Carolina Botanical Garden The infamous Venus flytrap, Dionaea muscipula, found across North Carolina and into South Carolina, has been seen to be declining in recent years. It is currently under review for federal listing, is ranked G2 on NatureServe, and considered vulnerable by RedList. Threats to this charismatic plant include poaching, […]

Conservation Genetics in Lichens: The Case of the Rock Gnome

Jessica L. Allen, PhD, Southeastern Center for Conservation, Atlanta Botanical Garden Dr. Allen outlines a conservation genomics approach to assessing genetic diversity between geographically separated populations of the Rock Gnome lichen, a Southern Appalachian endemic. Her results show that each locale sampled has a genetically distinct population. This suggests that the management plan for this lichen should include protecting […]

The Ecology of Hybridizing Pitcher Plants in Isolated Mountain Bogs

Dr. Rebecca Hale, University of North Carolina, Asheville Wayne Morgan, UNC Asheville Biology Elise Powell, UNC Asheville Biology Leila Beikmohamadi, Western Carolina University, Psychology Mara Alexander, US Bureau of Land Management Caroline Kennedy, UNC Asheville Biology Jennifer Rhode Ward, UNC Asheville Biology Pitchers of the purple pitcher plant, Sarracenia purpurea, are distinctly shorter and broader […]

Dr. Jeremie Fant, Chicago Botanical Garden Many land managers are aware of the value of genetic data for making important decisions for the management of rare species. In the ever-expanding world of Genomics, practitioners now have access to more comprehensive and accurate data. However, the speed of change can make it hard to keep up […]

Ecology and Conservation of the Federally-Listed Coastal Cactus Harrisia aboriginum in SW Florida

Shawn C. McCourt, Sally M. Chambers, and Bruce K. Holst, Marie Selby Botanical Gardens The genus Harrisia (Cactaceae) comprises 20 narrowly endemic species of night-blooming cacti with two widely separated geographic ranges, including South America south of Amazonia, as well as the West Indies and southern Florida. Commonly known as aboriginal prickly-apple, H. aboriginum is […]

Conserving Genetic Diversity in Seed Collections

Joe Davitt, Institute for Conservation Research, San Diego Zoo Global Maintaining a plant species’ genetic diversity can contribute to adaptive potential, prevent inbreeding effects, and potentially preserve traits such as drought tolerance and disease resistance, all of which are critical in a changing climate. Seed collections are often the best method of conserving the genetic diversity of rare plant populations ex-situ, […]

Plant Genetics Conservation Workshop, 2019, Introductions, Overview

Christy Powell, San Diego Zoo Global San Diego Zoo Global’s Christy Powell opens the 2019 Plant Genetics Conservation workshop at San Diego Zoo Global with a welcome to participants, some background on San Diego Zoo Global, and an inspirational story about a fern that has benefitted from conservation efforts.

Ongoing investigations into population genetics of cycads

Christy Powell, Brian Dorsey, San Diego Zoo Global, Huntington Botanical Garden As the most endangered group of plants on the planet, cycads (Cycadales) face a number of threats to their continued existence. Efforts to preserve these iconic plants (in situ reserves and ex situ collections) could benefit greatly from a better understanding of population genetic […]

Conservation Genetics at the San Diego Zoo Institute for Conservation Research: A (personal) historical perspective

Oliver A. Ryder, Director, Conservation Genetics, Kleberg Endowed Chair, San Diego Zoo Institute for Conservation Research In January, 1975 genetics studies commenced at the San Diego with group of researchers who would become the core of CRES, the Center for Reproduction of Endangered Species – now the San Diego Zoo Institute for Conservation Research. Founded […]

Genetic Diversity Assessment of Sassafras albidum for Conservation Efforts

Fred Gouker, Abigail Moore, Kevin Conrad, Margaret Pooler, USDA-ARS U.S. National Arboretum, Floral and Nursery Plants Research Unit, Enviromental and Plant Biology Department, Ohio University Sassafras albidum is a well-known, ecologically important tree that is dispersed throughout the Eastern United States. Its root and bark oil were commonly used as a flavoring agent for many products […]

Applying genomic tools to aid the conservation of Torrey pines in the face of bark beetle threats

Dr. Stephanie Steele, San Diego Zoo Global The Torrey pine (Pinus torreyana) is a rare, iconic species that occurs naturally in only two locations in Southern California: in coastal San Diego County and on Santa Rosa Island. The species is of particular conservation concern due to prolonged drought which has increased susceptibility of trees to […]
