This study examines gene flow and population differentiation among populations of two species of the Hawaiian silversword alliance, Dubautia arborea and D. ciliolata, and compares divergence in putatively neutral microsatellite markers with divergence in leaf morphometric traits, which may be selectively important or physiologically linked to selectively important traits.

Results indicate that ecological and morphological diversification has driven genetic divergence at rapidly evolving microsatellite loci, whereas there is continuing lineage sorting at neutral sites in nuclear coding loci.

Investigation of NIDA research grade marijuana found to genetically group with Hemp samples along with a small subset of commercial drug-type Cannabis, suggesting that subjects consuming NIDAResearch grade marijuana may experience different effects than average consumers.

A PCR-based method was used to quantify genetic variation in four reintroduced populations of Abroniaumbellata ssp.
Do the island biogeography predictions of MacArthur and Wilson hold when examining genetic diversity on the near mainland California Channel Islands? Examples from endemicAcmispon(Fabaceae)
- M. Mcglaughlin, L. Wallace, K. Helenurm
- Environmental Science
- 1 March 2014
The equilibrium theory of island biogeography does not hold for measures of genetic diversity in the Channel Island endemic Acmispon based on island area and distance to the mainland, and plant diversity was a significant predictor of plastid genetic diversity when considering all samples.
Population genetic diversity and species relationships in the genus Rhinanthus L. based on microsatellite markers.

- 1 March 2014
Genetic variation and species relationships in 15 populations of six Rhinanthus species from three sections are studied, indicating close affinity between R. osiliensis, R. wagneri and R. angustifolius.
How much is enough? Minimum sampling intensity required to capture extant genetic diversity in ex situ seed collections: examples from the endangered plant Sibara filifolia (Brassicaceae)
- M. Mcglaughlin, L. Riley, M. Brandsrud, Erica Arcibal, Mark K. Helenurm, K. Helenurm

Findings indicate that theoretical guidelines for ex situ seed collections that recommend targeting 50 individuals per population overestimate the sampling effort required to adequately preserve common alleles, but may underestimate the effort necessary to capture most alleles in wild populations.

Examining the genetic integrity of a rare endemic Colorado cactus (Sclerocactus glaucus) in the face of hybridization threats from a close and widespread congener (Sclerocactus parviflorus)
- Anna L. Schwabe, J. R. Neale, M. Mcglaughlin
- Environmental Science, BiologyConservation Genetics
- 1 April 2015
Genetic integrity of sampled S. glaucus populations is intact, with relatively high diversity and low levels of inbreeding, indicating management should focus on protecting existing populations and preventing movement of material among genetically distinct regions.
Endemism in native floras of California’s Channel Islands correlated with seasonal patterns of aeolian processes
- L. Riley, M. Mcglaughlin
- Environmental Science
- 2016
This study revisits the hypothesis that dispersal to California’s Channel Islands follows a stepping-stone pattern from mainland California, based on earlier work indicating that the floras conform to classic island-biogeographic expectations, and suggests the importance of aoelian processes for island colonization.
