Conservation Genetics in Lichens: The Case of the Rock Gnome

Screenshot of Conservation Genetics in Lichens video.

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 […]

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 […]

Distinguishing Acuña cactus, a federally endangered species, from its close relatives using genetic information

Shannon Fehlberg, Desert Botanical Garden The Acuña cactus, Echinomastus erectocentrus var. acunensis, is an endangered species with a restricted distribution in the Sonoran Desert in southern Arizona and northern Sonora, Mexico. Population-level genetic analyses for this species are lacking, and taxonomic boundaries between E. erectocentrus var. acunensis and its close relatives E. erectocentrus var. erectocentrus […]
