Functional trait heritability and local climatic adaptation among grasses: A meta-analysis

Publications Posted on: October 02, 2019
Variation in climate has been demonstrated to be a powerful driver of selection and local adaptation among plant populations. Variation in functional traits among populations can also be indicative of the drivers of local adaptation. However, it is not clear to what extent species exhibit consistent patterns of local adaptation as revealed by common, heritable trait–environment relationships among populations.

Strong patterns of local adaptation in Great Basin plants

Science Spotlights Posted on: July 31, 2019
Natural selection varies across landscapes and populations often adapt to local environmental conditions. Using a literature review of common garden studies published between 1941 and 2017, we documented the commonness of three signatures of local adaptation in plants native to North America's Great Basin. Our results demonstrate widespread habitat‐related population differentiation and local adaptation across the Great Basin. 

Strong patterns of intraspecific variation and local adaptation in Great Basin plants revealed through a review of 75 years of experiments

Publications Posted on: June 25, 2019
Variation in natural selection across heterogeneous landscapes often produces (a) among‐population differences in phenotypic traits, (b) trait‐by‐environment associations, and (c) higher fitness of local populations.

Informing native plant sourcing for ecological restoration: cold-hardiness dynamics, flowering phenology, and survival of Eriogonum umbellatum

Publications Posted on: April 09, 2019
Despite advances in restoration of degraded lands around the world, native plants are still underutilized. Selection of appropriate plant materials is a critical factor in determining plant establishment and persistence.

Developing pollinator-dependent plant materials for use in a growing restoration economy

Projects Posted on: March 08, 2019
Located on the Sierra Ancha Experimental Forest, this project uses a common garden approach to determine which plant species are best suited for supporting pollinator communities and are most appropriate for restoration activities. Findings from the study will be used to 1) improve pollinator habitat, 2) increase seed stocks of native flowering species for use in restoration, 3) inform U.S. seed zone guidelines and 4) help predict plant-pollinator response to climate change. This carries on a long tradition at the Sierra Ancha Experimental Forest of using common gardens in botanical research. As far back as the 1920s and 30s common gardens were used to study evapotranspiration rates of native herbaceous and shrub species as well as evaluate the potential use of certain species for erosion control. Some of these the same gardens are now being restored nearly a century later for use in this study.

Flower phenology and climate data for Artemisia tridentata populations

Datasets Posted on: March 15, 2018
This data publication contains 2012 flowering data for the 52 populations of big sagebrush (Artemisia tridentata) grown in 3 garden locations: Majors Flat and Ephraim in Idaho, as well as Orchard, Idaho. Data include geographical details, subspecies, julian date of flowering, and population climate variable information.

International Limber Pine Provenance Study (ILPPS): Rocky Mountain adaptive variation experiment

Projects Posted on: August 14, 2017
Limber pine is threatened by climate change, white pine blister, dwarf mistletoe, and mountain pine beetle. Scientists have planted limber pine in two contrasting environments to assess adaptive trait variation and plasticity, as well as climate interactions. Research such as the International Limber Pine Provenance Study (ILPPS) will support proactive managment to keep limber pine populations sustainable and prevent limber pine from following the same trajectory as whitebark pine.

Will phenotypic plasticity affecting flowering phenology keep pace with climate change?

Publications Posted on: December 30, 2016
Rising temperatures have begun to shift flowering time, but it is unclear whether phenotypic plasticity can accommodate projected temperature change for this century. Evaluating clines in phenological traits and the extent and variation in plasticity can provide key information on assessing risk of maladaptation and developing strategies to mitigate climate change.

Range-wide vulnerability of limber pine: White pine blister rust resistance and climate interactions

Projects Posted on: October 21, 2016
Forest surveys alone cannot predict species vulnerability as they cannot determine if the remaining healthy trees are at risk for disease or if they have heritable genetic resistance to support future populations. This project takes range-wide common garden (198 families) and artificial inoculation with Cronartium ribicola (causal agent of white pine blister rust) in order to better undertand host population vulnerability and sustainability.

Research helps conserve and restore shrub dominated ecosystems

Science Spotlights Posted on: October 14, 2016
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.
