Pre‐fire grazing and herbicide treatments can affect post‐fire vegetation in a Great Basin rangeland
Ecological Solutions and Evidence, 2023 Management of wildfire associated with spread of the highly invasive annual grass Bromus tectorum (cheatgrass) is a critical need in the western U.S. We investigated the utility of coupling common rangeland management strategies pre‐fire to modify post ...

INFLUENCE OF AGRICULTURAL SYSTEM ON THE CONTROL OF BROMUS TECTORUM ON WINTER WHEAT
LIFE SCIENCE AND SUSTAINABLE DEVELOPMENT, 2022 Bromus tectorum causes special problems because of its ability to reproduce through seeds and also because it’s relative tolerance to numerous herbicides. Extending new tillage systems, conservative systems specific to conservative sustainable agriculture, is a difficult task to accomplish under the circumstances of strong monocotyledonous weed ...

LONG-TERM EFFECTS OF TEBUTHIURON ON BROMUS TECTORUM
Western North American Naturalist, 2006 Abstract Use of herbicides to thin dense stands of Artemisia spp. (sagebrush) can free up resources for herbaceous plants and increase forage production, but may also facilitate weed invasion. We revisited a sagebrush thinning experiment in a north central Wyoming big sagebrush–grassland 11 years after application of tebuthiuron (N-[5-(1,1 ...

Pest Management Science, EarlyView.Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

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 ...

Functional traits can explain coordinated seedling responses to drought and freezing stress
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Limited plant establishment creates demographic bottlenecks that can alter vegetation trajectories in changing environments, yet it is unclear how common eco‐evolutionary indicators of plant strategy shape early response to key stressors.
