Current Research

My current research focuses on molecular and quantitative genetics of shrub and tree species. This research includes understanding the evolutionary relationships, population genetic structure, and adaptive genetic variation. Current projects include the following species: big sagebrush (Artemisia tridentata), blackbrush (Coleogyne ramosissima) and aspen (Populus tremuloides). This research employs various genetic techniques: common garden trials to measure adaptive variation in quantitative traits, next-generation sequencing to develop molecular markers and annotate genes, and genecology to develop association between traits and climate variables to infer seeds zones for current and future climates.

Research Interests

My research interests include population genomics, genecology, and phylogenetics of plants. I am particularly interested in using genetic approaches to address ecological interactions between plants and the environment. Knowledge from these studies can be used to inform seed transfer and assisted migration strategies. Richardson, Bryce A.; Meyer, Susan E. 2012.

Past Research

Much of a species demographic and evolutionary history is recorded into the DNA and phenotypic traits. Genetic research has an extremely broad use for basic and applied research. Molecular genetic data provide the insight into evolutionary relationships between plant taxa and assess intraspecific genetic diversity and structure. These data are critical in identifying unique or at risk populations, understand barriers to gene flow, and evaluate past climate change on demographics and biogeography. Genetics data can also assess environmental adaptation. Common gardens trials measure genetic responses to climate. This data is used to develop of seed zones for plant species. Knowledge of where to collect and plant seeds is critical to restoration success, sustainability of ecosystems and efficient use of funding.

Why This Research is Important

Knowledge of how plants are adapted to their environments is fundamental to ecological restoration and mitigating impacts from climate change. This research has applications for the development of current and future seed transfer zones, ensuring seed banks capture the genetic diversity of a species and other tools that enable restoration of natural ecosystems.

    The Seedlot Selection Tool and Climate-Smart Restoration Tool are publicly accessible web-based tools designed to match seed sources with reforestation and restoration planting sites, using user input locations and tolerance thresholds and built-in climate and genetic data. These tools fill a need for dynamic and accessible mapping tools for selecting seed sources that will be resilient to future climate change.​

    Diverse native forb communities are indicators of healthy ecosystems. Given the increasing frequency of disturbance and climate change perturbation affecting the establishment of native plant communities, restoration of native forbs is often required. RMRS staff and partners are focused on uncovering the genetic, evolutionary, and ecological underpinning of these understudied species to promote the appropriate application of native forbs in restoration.
    Students examining sagebrush with a large mountain range in the background.
    Adaptive traits can be dramatically altered by genome duplication. A common garden study of big sagebrush (Artemisia tridentata) shows that genome duplication (polyploidy) can affect below and above ground traits that have far reaching effects on reproduction, water uptake and interaction with neighbors.
    Healthy sagebrush common garden at Great Basin Experimental Range.
    Two common gardens were established for big sagebrush and blackbrush at the Great Basin and Desert Experimental Ranges in Utah, respectively. The experimental areas are ideal for studies in which plants representing multiple populations of a single species are grown together in common environments. These types of studies provide a useful approach for understanding species limits.  
    Collecting sagebrush volatiles (odors) in a common garden near Ephraim, Utah.
    Big sagebrush (Artemisia tridentata) is the dominant plant species across much of the Western U.S. and provide critical habitat and food for many endemic species, including the threatened greater sage-grouse. Sagebrush habitat is imperiled due to disturbances and increased wildfire frequency due to exotic annual grasses. Identification of big sagebrush subspecies is difficult, but critical for successful restoration. Researchers discover that volatiles emitted by sagebrush species and subspecies differ in consistent ways and can be used to accurately identify plants.

    Wildfire, invasive weeds, and climate change are threatening sagebrush ecosystems including the flora and fauna that are dependent upon them. Both Forest Service and BLM policies dictate that successful restoration requires putting the right seed in the right place. However, for many desert species little or no information is available to address these policies, including big sagebrush.
    Great Basin Native Plant Project Logo
    The Great Basin Native Plant Project seeks to increase the availability of genetically appropriate native plant materials and to provide the knowledge and technology required for their use in restoring diverse native plant communities across the Great Basin. This multi-state, collaborative research project was initiated in 2001 by the Plant Conservation Program of the BLM and the Grassland, Shrubland, and Desert Ecosystem Research Program of the Rocky Mountain Research Station.

    Sagebrush communities are the cornerstones of arid ecosystems in the West, mitigating soil erosion, fostering plant and animal biodiversity, storing carbon, and providing cover and forage for wildlife, such as the greater sage-grouse. However, these ecosystems are being compromised by increased fire frequency and climate change, coupled with encroachment of invasive plants. This research focuses on ecological genetics of big sagebrush (Artemisia tridentata). Conserving and restoring big sagebrush is critical for the recovery of sage-grouse (Centrocercus urophasianus) and other sagebrush-dependent wildlife species.
    The distribution of plant species and populations will likely be reshaped as climate changes. Understanding these changes is complex and requires the integration of multiple research disciplines including genetics, climate modeling and biogeography. This research focuses on blackbrush (Coleogyne ramosissima), a widespread shrub that straddles the ecotone, transition area between two plant communities, from the Great Basin and Mojave Desert ecosystems.
    Forbs are an integral component of terrestrial ecosystems and critical to pollinator health. However, we know very little about the biology of native forbs. Such knowledge is a prerequisite to developing restoration programs that use diverse forb species in restoration seeding.
    Plant performance for many populations of focal native forb species is being tested in experimental gardens across the Great Basin in order to improve how seeds are sourced for restoring native plant communities.
    The climate niche for Wyoming big sagebrush was model for contemporary and 2050 climate. Climate change is predicted to have a negative impact on this subspecies with a 39% reduction in climate niche space between now and 2050.
