The Impact of Non-Native Predators on Pollinators and Native Plant Reproduction in a Hawaiian Dryland Ecosystem
Abstract
This Final Report describes our research project that examined impacts of non-native invasive predators on pollination and native plant reproduction in Hawaii. We combined field observation, experimental manipulation, and laboratory analysis to examine interactions between eight focal native plants (endangered and common), insect pollinators (native and non-native), and predators. Synthesis of the data showed that invasive predator do affect pollinator-plant interactions both negatively and positively; however, most effects are negative. Rats and ants in particular had only negative effects on pollinator-plant interactions. Results can aid land managers in determining whether to control invasive predators in order to manage for pollination services and native plant reproduction.
