Abstract Details

2012, Master of Science, Miami University, Zoology.
As global demands increase for food, livestock, and biofuels, agricultural intensification could further increase the conversion of natural and semi-natural habitats into production. This intensification severely impacts natural plants and crops that rely entirely on pollination and pest control for fruit and seed production. I studied the species richness and composition of insect pollinators and natural enemies in 10 warm-season conservation grasslands. In Chapter 1, I tested richness, species composition, and trait composition (function­al diversity) of pollinating bees and predatory beetles against patch area and vegetative composition as well as landscape variables based on surrounding land use and cover. In Chapter 2, I tested richness, species composition, and functional diversity of predatory and parasitoid species against patch and landscape variables. Overall, patch-level processes regulated species richness and composition of pollinators, whereas the surrounding landscape context was more important in the species richness, composition, and functional diversity of predatory and parasitoid insects.
