Dr. Taylor directs Monarch Watch and conducts research on a variety of topics related to the evolution and ecological implications of life history traits in insects and plants.


My research efforts have included studies of reproductive isolating mechanisms in sulfur butterflies, reproductive and life history patterns in plants, comparative biology of European and Neotropical African honey bees and migratory behavior of monarch butterflies. Work in progress utilizes genetic markers to quantify the interactions between invading Neotropical African bees and resident European bees in North America. These investigations should clarify why, even after 40 years of hybridization, Neotropical African bees have retained their genetic integrity. Monarch Watch, an outreach program I initiated in 1992, now occupies much of my time.
