Triple Oxygen and Hydrogen Isotopes of Soil Water Across Climates, Seasons, and Depths

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Soil waters are a central component of the terrestrial water cycle. Their δ2H, δ18O, and d‐excess values contain rich information about hydroclimate, including the source of moisture and its evaporative history. Paleoclimate workers seek to investigate ancient hydroclimates via triple oxygen isotope geochemistry, termed Δ′17O, which is ...

A matter of timing: sagebrush steppe restoration seeding outcomes altered by species responses to warmer spring temperatures and interannual weather variation

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Restoration outcomes in cold desert ecosystems like sagebrush steppe are affected by weather variability, particularly during the spring, a critical time period for seedling establishment. Seedling emergence phenology is also highly variable among species in these ecosystems.

Downy Brome (Bromus tectorum) Is a Host for the Causal Agents of Fusarium Crown Rot of Winter Wheat in the Dryland Pacific Northwest

PhytoFrontiers
Fusarium crown rot (FCR) causes significant yield and quality loss of wheat in the Pacific Northwest (PNW) of the United States. The green bridge, defined in the 1980s as a phytopathological phenomenon at a landscape level, refers to any living plant ...

Green foxtail (Setaria viridis) and puncturevine (Tribulus terrestris) control in imazamox‐, quizalofop‐, and nicosulfuron‐resistant grain sorghum in semiarid Central Great Plains

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Recent commercialization of herbicide‐resistant (HR) grain sorghum [Sorghum bicolor (L.) Moench] hybrids, including iGrowth, DoubleTeam, and Inzen enables the use of imazamox, quizalofop, and nicosulfuron, respectively, for annual grass weed control.

Group effects of a non‐native plant invasion on rodent abundance

Ecosphere, 2019
Cheatgrass (Bromus tectorum) is the most prolific invading plant in western North America. Investigations determining the impact of this invasion on population state variables and community dynamics of rodents have largely occurred at the community or ...

Biosecurity risks from weeds in crop seed lots imported into Canada: prevalence, trends, and herbicide resistance [PDF]

NeoBiota
The international crop seed trade is a major pathway for the unintentional introduction of non-native invasive plant species and herbicide-resistant weeds, posing biosecurity threats to agriculture and ecosystems.

Phenology forecasting models for detection and management of invasive annual grasses

Ecosphere
Non‐native annual grasses can dramatically alter fire frequency and reduce forage quality and biodiversity in the ecosystems they invade. Effective management techniques are needed to reduce these undesirable invasive species and maintain ecosystem ...

Consequences of seed origin and biological invasion for early establishment in restoration of a North American grass species.

PLoS ONE, 2015
Local, wild-collected seeds of native plants are recommended for use in ecological restoration to maintain patterns of adaptive variation. However, some environments are so drastically altered by exotic, invasive weeds that original environmental ...

Associated eulophids (Hymenoptera: Eulophidae) with some Poaceae in the northwestern Iran [PDF]

نامه انجمن حشره‌شناسی ایران
During a survey conducted in West Azarbaijan Province, northwestern Iran, various grasses (Poaceae) were collected from 2021 to 2023. Plant tissue samples of Bromus tectorum (L.) Nevski, Dactylis glomerata L., Lolium perenne L., Phalaris minor Retzand ...
