Eco‐evolutionary context modifies a destructive plant invader's response to climate

New Phytologist, Volume 251, Issue 5, Page 2980-2994, September 2026.
Abiotic environment–fitness relationships can be shaped by evolutionary, ecological, and eco‐evolutionary contexts. Summary Understanding the relationship between climate and fitness will be important when predicting how plant populations respond to climate change. We conducted a replicated common garden experiment (4 sites × 2 yr) with 96 genotypes (n

Effect of Competition by Cheatgrass on Shoot Growth of Idaho Fescue [PDF]

Journal of Range Management, 1995
Ability to compete with alien weeds may be one factor enabling high-seral, native bunchgrasses to persist on degraded rangelands. This study examined the effect of competition from cheatgrass (Bromus tectorum L.) on shoot growth of Idaho fescue (Festuca idahoensis. Elmer).

Grazing intensity effects on herbaceous community composition in burned sagebrush steppe

Ecosphere, 2023
There is limited knowledge of grazing impacts on longer term plant community dynamics following fire in sagebrush steppe. This study evaluated vegetation response to different intensities of deferred rotation cattle grazing over 16 years (2007–2022) on ...

De novo genome assembly of the fungal plant pathogen Pyrenophora semeniperda. [PDF]

PLoS ONE, 2014
Pyrenophora semeniperda (anamorph Drechslera campulata) is a necrotrophic fungal seed pathogen that has a wide host range within the Poaceae. One of its hosts is cheatgrass (Bromus tectorum), a species exotic to the United States that has invaded natural

Trajectories and drivers of compositional and functional variation in sagebrush steppe restoration

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Restoration success is often challenged by unpredictable and undesirable outcomes, especially in arid systems like the sagebrush steppe. In an 11‐year study in Grand Teton National Park, climatic conditions during establishment and local soil texture drove long‐term differences in plant community composition and functional traits.

Post-Fire Vegetation Response in a Repeatedly Burned Low-Elevation Sagebrush Steppe Protected Area Provides Insights About Resilience and Invasion Resistance

Frontiers in Ecology and Evolution, 2020
Sagebrush steppe ecosystems are threatened by human land-use legacies, biological invasions, and altered fire and climate dynamics. Steppe protected areas are therefore of heightened conservation importance but are few and vulnerable to the same impacts ...

Ten‐year ecological responses to fuel treatments within semiarid Wyoming big sagebrush ecosystems

Ecosphere, 2022
Sagebrush ecosystems of western North America are threatened by invasive annual grasses and wildfires that can remove fire‐intolerant shrubs for decades. Fuel reduction treatments are used ostensibly to aid in fire suppression, conserve wildlife habitat,

Quantifying avian resilience to habitat change to support conservation decision‐making

Ecological Applications, Volume 36, Issue 5, July 2026.
Abstract Habitat loss and degradation are two of the main drivers of contemporary avian population declines. Wildlife managers are increasingly advocating for tools that provide decision support to set priorities for restoration or conservation efficiently.

Invasion of perennial sagebrush steppe by shallow-rooted exotic cheatgrass reduces stable forms of soil carbon in a warmer but not cooler ecoregion

Environmental Research Communications
Soil organic carbon (‘SOC’) in drylands comprises nearly a third of the global SOC pool and has relatively rapid turnover and thus is a key driver of variability in the global carbon cycle.

Multi-Species Inference of Exotic Annual and Native Perennial Grasses in Rangelands of the Western United States Using Harmonized Landsat and Sentinel-2 Data

Remote Sensing, 2022
The invasion of exotic annual grass (EAG), e.g., cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), into rangeland ecosystems of the western United States is a broad-scale problem that affects wildlife habitats, increases wildfire ...
