A draft genome provides hypotheses on drought tolerance in a keystone plant species in Western North America threatened by climate change

Ecology and Evolution, 2021
Climate change presents distinct ecological and physiological challenges to plants as extreme climate events become more common. Understanding how species have adapted to drought, especially ecologically important nonmodel organisms, will be crucial to ...

Neutrophil Immunomodulatory Activity of Farnesene, a Component of Artemisia dracunculus Essential Oils

Pharmaceuticals, 2022
Despite their reported therapeutic properties, not much is known about the immunomodulatory activity of essential oils present in Artemisia species. We isolated essential oils from the flowers and leaves of five Artemisia species: A.

Essential Oil Yield, Composition, and Bioactivity of Sagebrush Species in the Bighorn Mountains

Plants, 2022
Sagebrush (Artemisia spp.) are dominant wild plants in large areas of the U.S., Canada and Mexico, and they include several species and subspecies. The aim was to determine if there are significant differences in essential oil (EO) yield, composition ...

Burial increases seed longevity of two Artemisia tridentata (Asteraceae) subspecies

• Premise of the study: Seed longevity and persistence in soil seed banks may be especially important for population persistence in ecosystems where opportunities for seedling establishment and disturbance are unpredictable. The fire regime, an important

Influence of directional side of sagebrush canopies and interspaces on microhabitats

Basic and Applied Ecology, 2023
Shrubs can contribute to spatial heterogeneity in plant communities by creating distinct microsites under their canopies compared to between their canopies (interspaces).

Seasonal Trap Abundance of Two Species of Psilochalcis Kieffer (Hymenoptera: Chalcididae) in Rangelands of the Eastern Great Basin of Utah, USA

Land, 2022
Two species of Psilochalcis (Hymenoptera: Chalcididae) wasps occurring in the Great Basin region of the western United States were sampled from three locations in central Utah (USA) over a two-year period using Malaise traps. Each location is composed of

Grazing effects on shrub-induced resource islands and herbaceous vegetation heterogeneity in sagebrush-steppe communities

Global Ecology and Conservation, 2022
Spatial heterogeneity in plant communities promotes coexistence and diversity by providing a variety of niches for different species. In shrub-steppe communities, shrubs create distinct microsites under their canopies (canopy microsites) compared to ...

Insights into transcriptomes of big and low sagebrush.

PLoS ONE, 2015
We report the sequencing and assembly of three transcriptomes from Big (Artemisia tridentata ssp. wyomingensis and A. tridentata ssp. tridentata) and Low (A. arbuscula ssp. arbuscula) sagebrush.

Preference of Pygmy Rabbits (Brachylagus idahoensis) for Various Populations of Big Sagebrush (Artemisia tridentata)

, 1982
Pygmy rabbits were used in feeding trials to rate preference of 15 populations of 2 subspecies of big sagebrush (Artemisia tridentata ssp. vaseyana, Artemisia tridentata ssp. tridentata).
