Landscape structure influences modularity patterns in farm food webs: consequences for pest control.

The article presents a study which examines the effects of landscaping on modularity patterns in farm food webs. The study uses organic and conventional farms, wherein modularity, habitat groups, and interactions among herbivores, plants, and parasitoid species were observed. Result shows modularity of 0.70 to 0.82 in organic, while conventional farms show 0.73 to 0.88 modularity and lower module links. Moreover, landscaping is shown to have little effects on habitat groups diversity.
