Yield responses of wheat to mulching practices in dryland farming on the Loess Plateau.

PLoS ONE, 2015
Improving farming practices of soil and water conservation has profound effects on the yield of wheat (Triticum aestivum L.) in dryland farming regions of the Loess Plateau in China. Mulching has proven to be an effective practice to increase crop yield,

Arthropod conservation in roadside verges: Unmown refuges outperform mowing equipment changes

Insect Conservation and Diversity, EarlyView.
While roadside verges might have potential as connecting corridors for grassland habitats and their inhabitants, roadside mowing negatively impacts grassland arthropod densities. In contrast to unmown refuges, all mowing techniques harmed grassland arthropods, with no significant differences between mowing equipment.

Evaluating Syrphid Fly Predation on Aphids Under Controlled and Field Conditions in High Tunnels: A Comparative Study With Lacewings

Journal of Applied Entomology, EarlyView.
ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

Embedded Pesticide Use: Exploring the Pesticide‐Land Nexus

Journal of Agrarian Change, EarlyView.
ABSTRACT Since the turn of the century, global land grabs, farmland financialization and land‐based food sovereignty movements have returned the land question to the heart of agrarian studies. Meanwhile, abiding interest in pesticides has been reanimated in the face of changes in production, regulation and knowledge of toxicity.

Multivariate trait profiling and genetic diversity in a global foxtail millet germplasm panel

Plant Biology, EarlyView.
Four elite foxtail millet groups discovered from 260 accessions: perfect for breeding climate‐resilient, high‐yielding dual‐purpose crops. Abstract Foxtail millet (Setaria italica L.), known for its climate resilience and dual‐purpose utility, is underutilized in breeding programs despite its agricultural potential.

Seeding in single species aggregations promotes evenness of diverse shrub species in Banksia woodlands in the first year of growth

Restoration Ecology, EarlyView.
Abstract Introduction Species interactions are an overlooked yet important determinant of plant community assembly in ecological restoration. Specifically, they may determine species that are helped or hindered by neighboring plants during community assembly. Evidence suggests that intraspecific aggregation in combination with interspecific segregation
