Conservation genomics of Dithyrea maritima (Brassicaceae) beach spectaclepod

Kristen Hasenstab-Lehman, C. Matt Guilliams, Santa Barbara Botanic Gardens Dithyrea maritima (Davidson), or beach spectaclepod, is a dune specialist endemic to coastal dunes from central California, United States, to northwestern Baja California, Mexico. Individuals of this perennial herb spread by rhizomes, forming a diffuse colony of ramets, each terminating in rosette of 1 to several fleshy leaves, […]

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, […]

Genetic diversity, structure and distribution of Australian Cycas

Manuel Luján, Jian Liu, Nathalie Nagalingum, California Academy of Sciences, Kunming Institute of Botany, Chinese Academy of Sciences Rare plant species exhibit narrow geographic distribution and are often considered to have smaller populations and lower levels of genetic diversity compared to their more common relatives. The genus Cycas includes about 117 species, 32 of which are […]

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 […]

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

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 […]

Encephalartos heenanii – A Pollination Success Story

Paul Mills, Ganna Walska Lotusland Ganna Walska Lotusland has many important plant collections, but none are more important from a conservation standpoint than the cycad collection. In the collection there are three mature individuals of Encephalartos heenanii which is now believed to be extinct in the wild. Ganna Walska Lotusland is working with the IUCN […]

ddRADseq Approach for Conservation Management of Ex-situ Populations

Cynthia Steiner, Aryn Wilder, Debra Shier and Natalie Calatayud, San Diego Zoo Institute of Conservation Research Among the main roles of conservation management is to mitigate the negative effect of anthropogenic activities in nature by ensuring the persistence of biodiversity and species in the wild. Conservation geneticists have recently developed a new toolbox of genomic […]

Trials and Tribulations of Using RADseq for Large and Complex Genomes

Dr. Sally M Chambers, Marie Selby Botanical Gardens Next generation sequencing technologies have rapidly developed over the past decade, providing new avenues for scientists working on non-model organisms to study patterns at the genome level. Techniques can be used to drastically simplify a complex genome and multiplex samples, which help make these sequencing platforms more […]

Applying Genomics to Conservation

Dr. Aryn Wilder, Institute for Conservation Research, San Diego Zoo Global Human activity has left species worldwide on the brink of extinction, where they are susceptible to the loss of genetic diversity and the accumulation of deleterious mutations that reduce adaptive potential and increase extinction risk. The application of modern genomic tools allows us to more […]
