Simulated big sagebrush regeneration supports predicted changes at the trailing and leading edges of distribution shifts

Ecosphere, 2015
Many semi‐arid plant communities in western North America are dominated by big sagebrush. These ecosystems are being reduced in extent and quality due to economic development, invasive species, and climate change.

A matter of timing: sagebrush steppe restoration seeding outcomes altered by species responses to warmer spring temperatures and interannual weather variation

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Restoration outcomes in cold desert ecosystems like sagebrush steppe are affected by weather variability, particularly during the spring, a critical time period for seedling establishment. Seedling emergence phenology is also highly variable among species in these ecosystems.

Intercellular cavities in the rays of Dicotiledonous woods

Lilloa, 1938
An intercellular cavity within a radius differs from a radial gum canal because it is relatively short in length. Such cavities can be normal or traumatic.

A comparison and development of methods for estimating shrub volume using drone‐imagery‐derived point clouds

Ecosphere
Shrub volume is used to calculate numerous, essential ecological indicators in rangeland ecosystems such as biomass, fuel loading, wildlife habitat, site productivity, and ecosystem structure.

Occupancy and abundance of predator and prey: implications of the fire‐cheatgrass cycle in sagebrush ecosystems

Ecosphere, 2016
Sagebrush (Artemisia tridentata) ecosystems are declining due to biological invasions and changes in fire regimes. Understanding how ecosystem changes influence functionally important animals such as ecosystem engineers is essential to conserve ...

Potential for post‐fire recovery of Greater Sage‐grouse habitat

Ecosphere, 2019
In the western United States, fire has become a significant concern in the management of big sagebrush (Artemisia tridentata Nutt.) ecosystems. This is due to large‐scale increases in cover of the fire‐prone invasive annual cheatgrass (Bromus tectorum L.)

Asteraceae : Artemisia tridentata

, 2015
Artemisia tridentata is an erect, branching, aromatic, evergreen shrub, having both a deep taproot and a broad shallow root system, and growing from 0.5 to 3 m in height. The older stems are dark colored and are often gnarled with exfoliating bark.

Spectrophotometry of Artemisia tridentata to Quantitatively Determine Subspecies

, 2018
Ecological restoration is predicated on our abilities to discern plant taxa. Taxonomic identification is a first step in ensuring that plants are appropriately adapted to the site.
