European Journal of Organic Chemistry, Volume 29, Issue 12, 23 March 2026.The work outlined herein covers a series of novel herbicidal lead structures that possess a pyrrolidinyl pyrazole carboxamide scaffold as a key structural feature, carrying further substituted benzyl side chains. Based on scaffold hopping approaches from known fungicidal and herbicidal compounds and utilizing an optimized synthetic approach, a broader ...

Defoliation Effects On Bromus Tectorum Seed Production: Implications For Grazing [PDF]
Rangeland Ecology & Management, 2008 Abstract Cheatgrass ( Bromus tectorum L.) is an invasive annual grass that creates near-homogenous stands in areas throughout the Intermountain sagebrush steppe and challenges successful native plant restoration in these areas. A clipping experiment carried out at two cheatgrass-dominated sites in eastern Oregon (Lincoln Bench and Succor Creek ...

Inter‐seeding legumes in dryland wheat cropping systems
Agronomy Journal, Volume 118, Issue 2, March/April 2026.Abstract In Northeastern Oregon, weed infestations pose a major constraint on winter wheat (Triticum aestivum L.) yield. A field study was initiated in October 2021 and conducted for three more years (2022, 2023, and 2024) to assess the potential of inter‐seeded legumes in continuous winter wheat on weed suppression and wheat yields.

Invertebrate community response to fire and rodent activity in the Mojave and Great Basin Deserts
Ecology and Evolution, 2019 Recent increases in the frequency and size of desert wildfires bring into question the impacts of fire on desert invertebrate communities. Furthermore, consumer communities can strongly impact invertebrates through predation and top‐down effects on plant

Lack of capture‐induced mortality of neonates associated with variation in handling protocols
Wildlife Society Bulletin, Volume 50, Issue 1, March 2026.We found that handling metrics (e.g., handling time, number of collectors, and age at capture) had limited or no influence on the survival of neonatal mule deer, desert bighorn sheep, and Rocky Mountain bighorn sheep within the first few days of life. Furthermore, we found that handled mule deer and Rocky Mountain bighorn neonates were recruited at a ...
