Weed spatial patterns and temporal stability were shaped by species life forms and the cropping systems implemented in the plots. Weed aggregation was more pronounced in conservation agriculture and among perennials. Patch stability was primarily governed by species life form and was stronger among perennials. Abstract BACKGROUND The aggregated spatial

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Composition Theory: A Pragmatist Specification of the Mesosocial
ABSTRACT This article develops composition theory as a pragmatist specification of the mesosocial. Existing theories describe situated social life without adequately explaining the mechanisms that produce it. Recent pragmatist scholarship has established important foundations: Gross on mechanisms, Lizardo on habit, and Hallett on inhabited ...
