Assessing landscape complexity using remotely sensed and field based measurements : does landscape complexity drive leafroller parasitism rates on Oregon caneberry farms?

Creator:

Winfield, Tammy L.

Abstract:

Landscape heterogeneity is thought to differ among farm management types (i.e. organic and conventional), and this difference is hypothesized to result in variations in pest control by natural enemies. However, it is unclear if these variations in pest control are driven by landscape structure or by farm management practices themselves....

Quantifying the Potential of Native Plants for Improving Pollination and Biological Control in Agroecosystems

Creator:

Winfield, Tammy L.

Abstract:

Agricultural areas can be inhospitable to the attraction and maintenance of beneficial insects like natural enemies and pollinators and this can result in a decrease in the ecosystem services of pollination and pest control that these insects supply. If habitat can be created and maintained on-farm, an increase in the...
