Genetic structure of three Endangered Plants of the Santa Rosa Plain: Burke's goldfields (Lasthenia burkei), Sonoma sunshine (Blennosperma bakeri), and Sebastopol meadowfoam (Limnanthes vinculans)

  title={Genetic structure of three Endangered Plants of the Santa Rosa Plain: Burke's goldfields (Lasthenia burkei), Sonoma sunshine (Blennosperma bakeri), and Sebastopol meadowfoam (Limnanthes vinculans)},
  author={Debra R. Ayres and Christina M. Sloop},
Burke's goldfields (Lasthenia burkei), Sonoma sunshine (Blennosperma bakeri), and Sebastopol meadowfoam (Limnanthes vinculans) are herbaceous annual plants that inhabit vernal pool and swale habitats mainly on the Santa Rosa Plain of Sonoma County, California. All are Federallyand State-listed as endangered. The goal of our research was to determine the genetic variation between populations in order to inform conservation efforts as to the distinctiveness of populations for seed banking and ex…

Conservation genetics of Butte County meadowfoam (Limnanthes floccosa ssp. californica Arroyo), an endangered vernal pool endemic

This study confirms previous isozyme-based results and suggests that the loss of any population would represent a significant loss in the species’ genetic diversity, and recommends close comparison of microhabitats of declining populations with genetically similar populations to recover declining populations.



The clonal and population structure of a rare endemic plant, Wyethia reticulata (Asteraceae): allozyme and RAPD analysis

It is postulated that large, long‐lived clones dominated genetic relationships within populations but also provided opportunities for gene flow between populations on a longer time scale.

Microhabitat distribution of two Florida scrub endemic plants in comparison to their habitat-generalist congeners.

Comparing microhabitats of two pairs of congeners that differ in habitat specificity and co-occur in one distinct habitat type, Florida rosemary scrub, suggests that P. basiramia and L. cernua are specialized on bare sandMicrohabitat specialization may limit the distribution of these rare species.

Plant ecotypes: genetic differentiation in the age of ecological restoration

Population Genetics of Vernal Pool Plants : Theory , Data and Conservation Implications

One goal of population genetics is to quantify and explain genetic structure within and among populations. Factors such as genetic drift, inbreeding, gene flow and selection are expected to influence

Gene flow and the geographic structure of natural populations.

Of particular interest are those species for which direct methods indicate little current gene flow but indirect methods indicate much higher levels of gene flow in the recent past, and whose species probably have undergone large-scale demographic changes relatively frequently.

Effects of Cattle Grazing on Diversity in Ephemeral Wetlands

The results show that one should not assume livestock and ranching operations are necessarily damaging to native communities, and grazing helped maintain native plant and aquatic diversity in vernal pools.

Inference of population structure using multilocus genotype data.

A model-based clustering method for using multilocus genotype data to infer population structure and assign individuals to populations that can be applied to most of the commonly used genetic markers, provided that they are not closely linked.

Arlequin (version 3.0): An integrated software package for population genetics data analysis

A completely new graphical interface written in C++, a more robust semantic analysis of input files, and two new methods: a Bayesian estimation of gametic phase from multi-locus genotypes, and an estimation of the parameters of an instantaneous spatial expansion from DNA sequence polymorphism are introduced.

Adaptive evolutionary conservation: towards a unified concept for defining conservation units

This work reviews ESU concepts and provides a context‐based framework for delineating ESUs which circumvents much of this situation and accepts that differing criteria will work more dynamically than others and can be used alone or in combination depending on the situation.

Limnanthes vinculans, a New California Endemic

Limanthes vinculans (Limnanthaceae) is described as a new species belonging to section Reflexae. It is endemic to a small area of Sonoma County, California, and is most closely related toL. douglasii
