Identifying seed fill and health predictors to expand seed‐based restoration of a foundational bunchgrass

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Seed quality is vital for the success of seed‐based ecological restoration programs. Components like viability, germination, and dormancy often receive the most attention. But other aspects of seed quality, like seed fill and infection, are equally important.

Evolution of the North American seed‐harvester ant genus Veromessor (Hymenoptera: Formicidae)

open access: yesSystematic Entomology, EarlyView.
Phylogenomics resolves evolutionary relationships among Veromessor seed‐harvesting ants across arid western North America. Ecological and morphological traits evolved rapidly and repeatedly in response to habitat. Genomic and morphological species delimitations are broadly congruent despite polymorphisms in colour and colony founding.

Impacts of long‐fallow wheat stubble management on soil water, microclimate, and wheat yield in a Mediterranean climate

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Inadequate soil water for timely crop establishment in dryland agricultural production systems of the inland Pacific Northwest is a key limiting factor in crop production. It is important to identify management practices that reduce soil water evaporation in the long fallow season prior to seeding wheat (Triticum aestivum L.) in the fall. In a

Floral hemp biomass and cannabinoid yield response to moisture stress under irrigation in a semi‐arid climate

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Hemp (Cannabis sativa L.) was re‐legalized as an agricultural crop through the USDA 2018 Farm Bill, but cropping guidelines remain limited, especially for floral hemp grown for cannabinoid extraction. In this study, the response of direct‐seeded, field‐grown autoflower and full‐season hemp cultivars to varying rates of applied irrigation was ...

Soil health unaltered by conversion from no‐till to occasional tillage

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Achieving greater productivity and ecological sustainability of agricultural soils requires moving beyond conventional management practices. No‐till (NT) enhances soil health while presenting weed management and nutrient stratification challenges.
