Kin discrimination in plants: overview and implications for population and community ecology

Biological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Addressing multiple management goals during roadside restoration: reducing weed invasion and fire risk while enhancing native plants and pollinator habitat in semiarid, invaded grasslands

Restoration Ecology, EarlyView.
Abstract Introduction Roadside vegetation management efforts often target a single desirable outcome; however, we frequently have multiple management goals for restoration. Multiple goals may be achieved concurrently, but the efficacy of roadside revegetation methods is largely unclear, especially when multiple methods are combined.

Earlier fall precipitation and low severity fire impacts on cheatgrass and sagebrush establishment

Ecosphere, 2020
In arid and semiarid ecosystems, invasion by exotic grasses may be driving state changes in vegetation defined by losses of native shrub communities.

Herbivory Amplifies Adverse Effects of Drought on Seedling Recruitment in a Keystone Species of Western North American Rangelands

Plants, 2022
Biotic interactions can affect a plant’s ability to withstand drought. Such an effect may impact the restoration of the imperiled western North American sagebrush steppe, where seedlings are exposed to summer drought.

DNA metabarcoding reveals key floral resources for native pollinators in post‐fire landscapes

Ecological Applications, Volume 36, Issue 7, October 2026.
Abstract Wildfires are a natural disturbance in dry ponderosa pine forest ecosystems, and are increasing in frequency and severity across western North America. The effects of wildfire on biotic and abiotic conditions have important implications for higher trophic levels, including native bees. We sought to quantify the responses of flowering plants to

Fuel reduction treatments reduce modeled fire intensity in the sagebrush steppe

Ecosphere, 2022
Increased fire size and frequency coupled with annual grass invasion pose major challenges to sagebrush (Artemisia spp.) ecosystem conservation, which is currently focused on protecting sagebrush community composition and structure. A common strategy for

Cytotype and local adaptation drive phenotypic variation in two subspecies of big sagebrush (Artemisia tridentata)

Ecosphere
Big sagebrush (Artemisia tridentata) is a widespread and locally dominant shrub throughout many ecosystems in western North America. A. tridentata ssps. tridentata and wyomingensis are two subspecies whose populations occupy the warm‐arid regions of the ...

Fire regime shift reveals 17th century socio‐ecological change in the Rio Grande del Norte National Monument, New Mexico

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Humans have influenced ecosystems for millennia, and social changes can have notable ecological effects. Recent human influence on ecosystems is exemplified by the collapse of fire regimes circa 1900 in the western United States due to increased grazing, fire suppression, and declining Indigenous fire use.

Effects of wildfire on the distribution of mammals and birds in a working shrub‐steppe landscape

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract The intensity, frequency, and extent of wildfire have increased drastically in the sagebrush (Artemisia spp.) ecoregion within Washington, USA, over the last few decades. Wildfire on this landscape, already modified and fragmented by agriculture and other disturbances, may challenge the persistence of wildlife that depend on continuous ...
