For my dissertation I investigated whether the provision of songbird nest boxes may conserve declining bird populations in California vineyards, and whether these insectivorous birds provide growers with ecosystem services in the form of pest control. As a postdoctoral fellow, I have expanded the scope and scale of this research program to model arthropod population dynamics in patchy vineyard-forest landscapes and directly link avian predation to food sources via molecular DNA analysis of predator fecal samples. My goal is to understand prey availability through time and space, so that avian conservation efforts result in successful, reproductively viable predator populations in bird-friendly agroecosystems.
