Research in the Nason Lab

Announcement

Research in the Nason Lab lab focuses on both pattern and process in the evolution of plants and their associated insect herbivores and pollinators. From a population genetic standpoint, “pattern” includes the organization or structuring of molecular genetic variation within and among individuals, populations, and species. Because genetic structure is an evolving character, when viewed from a multilocus or genomic perspective, observed patterns in the data can be seen to reflect different evolutionary forces and histories. While molecular tools provide a powerful approach for quantifying genetic variation, inferring the relative importance of these forces can be problematic when explanatory hypotheses are generated post hoc from the genetic evidence alone. As a result, in our work we combine genetic data analysis with a sound knowledge of a species’ natural history, and, when appropriate, hypotheses generated from historical biogeographical data. In my experience this integrative approach often provides a more insightful and statistically rigorous means of inferring evolutionary “process” than do purely ecological or genetic methods.
