Research Description

Pollination Ecology, Conservation, and Restoration

Harmon-Threatt is a pollination ecologist with broad interests in understanding the patterns and processes that govern plant-pollinator interactions for conservation. Pollinators play a vital role in plant reproduction, food production and ecosystem stability but are believed to be declining globally. Her work focuses on identifying and understanding patterns in natural environments to help conserve and restore pollinator diversity. With a particular focus on bees, she investigates how a number of factors at both the local and landscape scale, including plant diversity, isolation and bee characteristics, effect bee diversity in local communities.
