Given the high cost of restoration and the underlying assumption that reducing annual grass
abundance is a necessary precursor to rangeland restoration in the Intermountain West …

Intercrops have been associated with greater yields and pest and weed control compared
with sole crops. In this field experiment, we investigated agronomic performance and weed …

Organic producers often rely heavily on tillage for weed management, which can create
compaction, especially in headlands, and favor weed growth. To address Illinois organic …

Weeds are selected to produce overwhelming propagule pressure, and while vertebrate and
invertebrate seed predators destroy a large percentage of seeds, their ecosystem services …

Questions Is conifer colonization on primary successional sites limited by propagule
availability or environmental filters? How do nitrogen‐fixing pioneer species (L upinus …

At the field scale, weeds generally appear aggregated rather than randomly distributed, and
this aggregation is linked to the spatial heterogeneity of biotic and abiotic factors. Crop …

Summary 1 Seed banks are important to many plant populations, yet we lack clear
understanding of how environmental factors promote seed bank formation. We …
