William F. Morris

Bill Morris studies the population ecology of plants and insects (both herbivores and pollinators). Current projects include: the population dynamic consequences of constitutive and inducible resistance in plants, the maintenance of mutualistic interactions between flowering plants and nectar-robbing pollinators, the use of population-level attributes to detect biotic responses to ongoing environmental changes, and the use of mathematical models to assess viability of threatened and endangered populations. The common thread uniting these projects is that they combine field experiments and mathematical models to study population dynamics in natural and managed systems.
