Genecology of Thurber's Needlegrass (Achnatherum thurberianum [Piper] Barkworth) in the Western United States

Publications Posted on: October 02, 2019
Thurber’s needlegrass (Achnatherum thurberianum [Piper] Barkworth) is a key restoration species in the Great Basin and surrounding areas, yet comprehensive studies of how climate relates to genetic variation and seed zones for restoration projects are lacking. Potentially adaptive phenotypic traits of 66 diverse populations of Thurber’s needlegrass were measured in common gardens at Central Ferry, Washington and Reno, Nevada in 2012 and 2013.

Plasticity in native perennial grass populations: Implications for restoration

Publications Posted on: September 14, 2019
Increasing the evolutionary potential of restored populations has become a viable objective of restoration activities. Choosing plant materials genetically adapted to the restoration environment is critical for success, and phenotypic plasticity may also contribute to establishment and persistence in disturbed environments.

Phenotypic selection on growth rhythm in whitebark pine under climatic conditions warmer than seed origins

Publications Posted on: May 22, 2019
Growth rhythm that is well synchronized with seasonal changes in local climatic conditions is understood to enhance fitness; however, rapid ongoing climate change threatens to disrupt this synchrony.

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.

Climate-related genetic variation in a threatened tree species, Pinus albicaulis

Publications Posted on: September 25, 2017
PREMISE OF THE STUDY: With ongoing climate change, understanding of intraspecific adaptive variation is critical for conservation and restoration of plant species. Such information is especially scarce for threatened and endangered tree species, such as Pinus albicaulis Engelm. Therefore, our principal aims were to assess adaptive variation and characterize its relationship with climate of seed origin. METHODS: We grew seedlings from 49 P.

Relating adaptive genetic traits to climate for Sandberg bluegrass from the intermountain western United States

Publications Posted on: October 07, 2015
Genetic variation for potentially adaptive traits of the key restoration species Sandberg bluegrass (Poa secunda J. Presl) was assessed over the intermountain western United States in relation to source population climate. Common gardens were established at two intermountain west sites with progeny from two maternal parents from each of 130 wild populations.

Genecology and seed zones for tapertip onion in the US Great Basin

Publications Posted on: October 03, 2014
The choice of germplasm is critical for sustainable restoration, yet seed transfer guidelines are lacking for all but a few herbaceous species. Seed transfer zones based on genetic variability and climate were developed using tapertip onion (Allium acuminatum Hook.) collected in the Great Basin and surrounding areas in the United States.

Comparative genetic responses to climate in the varieties of Pinus ponderosa and Pseudotsuga menziesii: clines in growth potential

Publications Posted on: October 02, 2014
Height growth data were assembled from 10 Pinus ponderosa and 17 Pseudotsuga menziesii provenance tests. Data from the disparate studies were scaled according to climate similarities of the provenances to provide single datasets for 781 P. ponderosa and 1193 P. menziesii populations.

Comparative genetic responses to climate for the varieties of Pinus ponderosa and Pseudotsuga menziesii: realized climate niches

Publications Posted on: October 02, 2014
The Random Forests classification algorithm was used to predict the occurrence of the realized climate niche for two sub-specific varieties of Pinus ponderosa and three varieties of Pseudotsuga menziesii from presence-absence data in forest inventory ground plots. Analyses were based on ca. 271,000 observations for P. ponderosa and ca. 426,000 observations for P. menziesii, with ca.
