Agricultural Natural Enemies Benefit Predominantly From Broader Scales Of Environmental Heterogeneity: A Quantitative Review, Aaron Iverson, Robyn Burnham, John Vandermeer
Agricultural Natural Enemies Benefit Predominantly From Broader Scales Of Environmental Heterogeneity: A Quantitative Review, Aaron Iverson, Robyn Burnham, John Vandermeer
The Great Lakes Entomologist
Naturally occurring predator and parasitoid communities are well known to respond to multiple scales of environmental heterogeneity within and around agroecoystems, yet our understanding of which scales are most influential on different functional guilds of enemies is limited. Using vote-counting methodology, we synthesized the results from 40 empirical studies that observed how natural enemy richness, diversity, or parasitism rate is affected by environmental heterogeneity at a local scale (e.g. a focal field), an intermediate scale (e.g. habitat in immediate proximity of a focal field), and landscape scale (e.g. habitat within >200 m radius around focal field). Heterogeneity at all scales …

Intercropping And Denisity Impacts In A Lettuce And Chard Agroecosystem, Sophia Moser
Master of Science in Environmental Sciences and Management Projects
Conventional agriculture that uses machinery management, synthetic fertilizers, and pesticides, is a contributor to greenhouse gas emissions, reduction of biodiversity and soil health. Agroecological methods, such as intercropping, have the potential to make farming more sustainable, financially feasible and to be implemented on a large scale. Gaps in agricultural research have led to limited information as to how intercropped arrangements can be adapted to be as productive as conventional systems. This research evaluates the ecological and economic performance of a lettuce and chard agroecosystem, specifically investigating the impact that density and intercropping has on plant productivity and profitability. Both species …
