e0“25 seeds of each of six weed species, including velvetleaf, wild mustard, yellow foxtail, common lambsquarters, redroot pigweed, and hairy galinsoga, were placed in the field”
e1“Exclosures showed that the majority of seed predation could be attributed to invertebrates: 43% out of a total of 56% seed predation for 11 d in 2002 and 40% out of a total of 58% seed predation for 4 d in 2003”

Other claims from this paper (4)
- Association Harpalus rufipes activity-density was positively correlated with mean seed predation in 2002 in the absence of vertebrates.
- Association Harpalus rufipes activity-density was not correlated with mean seed predation in 2003.
- Intervention effect Harpalus rufipes was more abundant in vegetated treatments, particularly red clover, than in recently tilled treatments planted to a fall cover crop.
- Recommendation Cover-cropping strategies should consider late-season weed management that keeps weed seeds on the soil surface.
