Population Genomics of a Cosmopolitan Weed Provides Insights Into Its Local Adaptation and Recent Demographic History

open access: yesMolecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Invasive plant species present a growing ecological and economic challenge, and often adapt rapidly to their novel environments through complex demographic and evolutionary processes. Invasion genomics offers powerful tools to disentangle these processes, but most studies rely on geographically narrow sampling across native and non‐native ...

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

open access: yesEcosphere, 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.)

Novel Approaches to Invasive Annual Grass Management: Assessing Efficacy and Impacts on Target Species and Plant Diversity

open access: yesApplied Vegetation Science, Volume 29, Issue 2, April/June 2026.
Understanding how target weeds and surrounding plant communities respond to traditional and novel management is essential to meeting agricultural sustainability goals. We monitored target species cover (Bromus tectorum) and plant community diversity for 3 years following management.

Detecting Pteridium arachnoideum and Tithonia diversifolia in a Multiclass Land‐Cover Framework in the Cerrado: A Deep Learning Time‐Series Benchmark With Spatial Cross‐Validation

open access: yesTransactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT This study presents the first deep‐learning time‐series benchmark for detecting two encroaching species in the Brazilian Cerrado: the native super‐dominant fern Pteridium arachnoideum and the invasive alien shrub Tithonia diversifolia. We evaluate 43 architectures across six families (CNNs, RNNs, Transformers, and three hybrid groups) on ...

Pre‐fire vegetation drives post‐fire outcomes in sagebrush ecosystems: evidence from field and remote sensing data

open access: yesEcosphere, 2019
Understanding the factors that influence vegetation responses to disturbance is important because vegetation is the foundation of food resources, wildlife habitat, and ecosystem properties and processes.

Invaders break assembly rules to beat the natives: how cheatgrass cheats [PDF]

open access: yesNeoBiota
Understanding how some introduced plants achieve invasive status while most simply become naturalized is a fundamental question in invasion ecology. Traditional approaches comparing native and introduced plants have linked ruderal traits such as annual ...

Cheatgrass is favored by warming but not CO2 enrichment in a semi‐arid grassland

open access: yesGlobal Change Biology, 2016
AbstractElevated CO2 and warming may alter terrestrial ecosystems by promoting invasive plants with strong community and ecosystem impacts. Invasive plant responses to elevated CO2 and warming are difficult to predict, however, because of the many mechanisms involved, including modification of phenology, physiology, and cycling of nitrogen and water ...

From vegetation to vulnerability: Integrating remote sensing and AI to combat cheatgrass-induced wildfire hazards in California

open access: yesEnvironmental and Sustainability Indicators
Wildfire risk is on the rise around the world. In places like California, this risk is further instigated by the invasive species cheatgrass (Bromus tectorum).

Understanding the Anomalies in Exotic Annual Grass Cover in Precipitation Scenario Maps of Rangelands in the Western United States

open access: yesRemote Sensing
In rangeland ecosystems of the western United States, invasion by exotic annual grass (EAG) poses a substantial threat to native biodiversity. Studies have shown that weather, especially precipitation, can greatly influence the rate of invasion and EAG ...
