Evaluation of Cytotoxicity of Sagebrush Plain Extract on Human Breast Cancer MCF7 Cells

open access: yesArmaghane Danesh Bimonthly Journal, 2013
Background & aim: Several studies have reported anti-cancer properties of sagebrush plain. The aim of this study was to evaluate the cytotoxicity of the methanol extract of sagebrush plain on human breast cancer MCF7 cells.

Growth and age dynamics of juvenile plants of a dominant shrub in North American drylands

open access: yesEcosphere
Long‐lived perennial species in drylands tolerate a range of environmental conditions over their lifespan, but young plants are more vulnerable to stressful conditions than mature plants.

Effects of uncrewed aerial vehicle–applied triclopyr plus fluroxypyr rates on weeds and desirable forbs in Kansas tallgrass prairie

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract We studied the impacts of uncrewed aerial vehicle (UAV)‐applied triclopyr + fluroxypyr on rangeland weeds and other forbs in native tallgrass prairie. Two rates were tested: high (0.63 kg ae ha−1 triclopyr + 0.21 kg ae ha−1 fluroxypyr) and low (0.21 kg ae ha−1 triclopyr + 0.07 kg ae ha−1 fluroxypyr).

Field research guided by citizen science and monitoring data reveal a novel alpine breeding distribution and vegetation associations of a declining, habitat-specialist songbird in Colorado, USA

open access: yesAvian Conservation and Ecology
Documenting the breeding habitat and distribution of migratory songbirds is essential for accurately assessing their conservation status. The “sagebrush” subspecies of the Brewer’s Sparrow ( Spizella breweri breweri ) breeds in greatest abundance in ...

Hemiparasitic Castilleja presence is correlated with increased plant biodiversity across montane plant communities

open access: yesAmerican Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Premise Root hemiparasites form haustoria in belowground roots of hosts to extract nutrients and water from the surrounding hosts. Through parasitic symbiosis, these plants disproportionately affect plant communities relative to their abundance by reducing host size, altering nutrient flow, and eventually increasing local biodiversity.

Ecosystem resilience is evident 17 years after fire in Wyoming big sagebrush ecosystems

open access: yesEcosphere, 2016
Recent policy has focused on prevention of wildfire in the sagebrush steppe in an effort to protect habitat for the greater sage grouse (Centrocercus urophasianus).

Comparative Patterns of Cuticular Hydrocarbon Diversity in Termites Across Castes and Nesting Life Types

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Cuticular hydrocarbon (CHC) profiles in termites show strong ecological structuring across life type, climate, and caste, based on a comparative analysis of published datasets. Despite this ecological signal, phylogenetic patterns are weak, indicating high evolutionary lability relative to other social insects.

Effects of Gunnison Sage-Grouse habitat treatment efforts on associated avifauna and vegetation structure

open access: yesAvian Conservation and Ecology, 2015
Conservation efforts over the last 20 years for the Gunnison Sage-Grouse (Centrocercus minimus) have involved extensive habitat manipulations done predominantly to improve brood rearing habitat for the grouse.

Decadal effects of fuel treatments and annual grass invasion on sagebrush ecosystem carbon stocks

open access: yesEcosphere, Volume 17, Issue 8, August 2026.
Abstract Fuel treatments are implemented across large spatial scales in sagebrush (Artemisia spp.) ecosystems of the US Intermountain West to limit wildfire risk and spread, but treatment effects on ecosystem carbon storage remain poorly understood. Fuel treatments can reduce aboveground carbon storage and may also influence belowground carbon storage ...
