A trait-based approach to comparative functional plant ecology: concepts, methods and applications for agroecology. A review (2012, background): “, 2009), may be related to lower weed-crop competition (Smith et al., 2009).”
Increasing Cropping System Diversity Balances Productivity, Profitability and Environmental Health (2012, background): “Future gains in more diverse systems may depend upon the application of ecological principles surrounding this relationship to cropping system design [31,32].”
Response and effect traits of arable weeds in agro‐ecosystems: a review of current knowledge (2017, background): “These traits reflect the amount of depleted resources, for instance due to light interception that is considered as the main limiting factor for weed growth, especially in conventional cropping systems (Holt, 1995), and soil resource uptake by plants (Smith et al., 2009).”
Weed-Species Abundance and Diversity Indices in Relation to Tillage Systems and Fertilization (2018, background): “…and diversity should be intensively studied as key aspects of both biodiversity conservation within agroecosystems (Marshall et al., 2003; Gibson et al., 2006; Power, 2010; Rassam et al., 2011) and integrated weed management (Maxwell and O’Donovan, 2007; Smith et al., 2010; Travlos, I., 2013).”
