Effects of tillage and irrigation in cereal fields on weed seed removal by seed predators (2009, background): “When combined with other (non-chemical) control tactics, seed predation may foster reductions in herbicide use (Westerman et al. 2005) and thus cut environmental and monetary costs.”
Influence of glyphosate-resistant cropping systems on weed species shifts and glyphosate-resistant weed populations (2009, background): “…rotation, the more diverse the weed species will be in he community (Anderson and Beck, 2007; Anderson et al., 2007; ardina et al., 2002; Heggenstaller and Liebman, 2005; Murphy t al., 2006; Swanton et al., 2006; Westerman et al., 2005) thus ncreasing the opportunity for weed specie shifts.”
How can we target the weed seedbank? (2006, methodology): “Conceptual (Liebman and Gallandt 1997) and simulation (Westerman et al. 2005) models indicate that the efficacy of management at one stage may contribute to practices targeting subsequent stages; system-level performance may not be apparent when a practice is considered in isolation.”
The Role of Ground Beetles (Coleoptera: Carabidae) in Weed Seed Consumption: A Review (2015, background): “The predicted losses can reduce weed populations substantially, and any further seed loss would result in a significant decrease in weed species such as velvetleaf in these cropping systems (Westerman et al. 2005).”
Crop Diversification for Improved Weed Management: A Review (2021, unknown): “[69] in CS and CS-triticale+ alfalfa-alfalfa).”
Stacked Crop Rotations Exploit Weed-Weed Competition for Sustainable Weed Management (2014, methodology): “Westerman et al. (2005) used matrix models to compare weed population dynamics in a 2-yr (maize-soybean) and reduced-input 4-yr (maizesoybean-triticale [3 Triticosecale Wittmack]-alfalfa) crop rotation and showed that despite only 18% of the herbicide input of the 2-yr rotation, population growth…”
Weed seed predation increases with vegetation cover in perennial forage crops (2010, unknown): “Several studies compared theweed seed predation rates and/or the abundances of seed predators in different crop species (Andersson, 1998; Zhang et al., 1998; Cromar et al., 1999; Kromp, 1999; Macdonald et al., 2000; Westerman et al., 2005; Menalled et al., 2006; O’Rourke et al., 2006, 2008).”
Feeding Preferences of Weed Seed Predators and Effect on Weed Emergence (2007, background): “Empirical studies and modeling have shown postdispersal seed mortality to be one of the most sensitive parameters in predicting velvetleaf and green foxtail densities the following year (Cardina et al. 1996; Jordan et al. 1995; Westerman et al. 2005).”
Integrating measurements of seed availability and removal to estimate weed seed losses due to predation (2006, methodology): “…that in a corn–soybean–triticale 1 alfalfa–alfalfa crop-rotation system, seed losses of 40% in the soybean phase or 27% in each phase would be sufficient to stabilize velvetleaf populations (Westerman et al. 2005); seed losses in excess of that would result in declining velvetleaf populations.”
Agronomic and Economic Performance Characteristics of Conventional and Low-External-Input Cropping Systems in the Central Corn Belt (2008, background): “, 2006), but this ecological interaction appears to have been particularly important for suppressing weed densities in the LEI systems (Davis and Liebman, 2003; Davis et al., 2003; Westerman et al., 2005).”
Functional biodiversity in the agricultural landscape: relationships between weeds and arthropod fauna. (2010, background): “Westerman et al. (2005) showed that predation by opportunist invertebrates can substantially reduce the surface weed seed stock.”
Impact of agricultural management on carabid communities and weed seed predation (2007, background): “This result is particularly significant because it further supports the notion that increasing predator abundance may lead to enhanced weed suppression in many agricultural systems (Westerman et al., 2005; Gallandt et al., 2005).”
