From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

Pest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Threat Integration Model for Sagebrush (TIMS): A framework for using spatial decision support tools for strategic management of invasive annual grasses and conifers in sagebrush ecosystems

Conservation Science and Practice, EarlyView.
The Threat Integration Model for Sagebrush (TIMS) combines multiple spatial decision support tools to provide a unified, actionable map of sagebrush ecosystem conditions across the western United States. TIMS improves upon existing tools by including multiple threats in the same map (invasive annual grass [IAG] and conifer encroachment), characterizing

Revisiting the Life Cycle of Dung Fungi, Including Sordaria fimicola. [PDF]

PLoS ONE, 2016
Dung fungi, such as Sordaria fimicola, generally reproduce sexually with ascospores discharged from mammalian dung after passage through herbivores. Their life cycle is thought to be obligate to dung, and thus their ascospores in Quaternary sediments ...

Intraspecific variation in an arbuscular mycorrhizal fungus affects a plant and an AMF community

New Phytologist, EarlyView.
Mesocosm placement within the growing facility. Summary Arbuscular mycorrhizal fungi (AMF) show substantial genetic, trait, and functional variation within species. Whether this intraspecific variability has community‐level consequences for plant and AMF communities is unclear.

Effects of invasive plants on fire regimes and postfire vegetation diversity in an arid ecosystem

Ecology and Evolution, 2019
We assessed the impacts of co‐occurring invasive plant species on fire regimes and postfire native communities in the Mojave Desert, western USA. We analyzed the distribution and co‐occurrence patterns of three invasive annual grasses (Bromus rubens ...

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.
