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)

Video screenshot

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, […]

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 […]

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, […]

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 […]

Preserving evolutionary potential in the face of rapidly changing conditions: the role of genetic rescue

Screenshot of Preserving evolutionary potential in the face of rapidly changing conditions: the role of genetic rescue video

Jill Hamilton, North Dakota State University Species evolutionary potential is tightly linked to both the amount and distribution of genetic variation available through which natural selection may act. Rare species present particular challenges under rapidly changing conditions where the genetic consequences of rarity may limit species ability to adapt to ongoing change. Thus in a […]
