Research

Evolution and Genomics/Proteomics of Adaptive Phenotypes

In the broadest sense, research in my laboratory focuses on the evolution of adaptive phenotypes – including traits related to fertilization success, behavior, and responses to environmental cues. We utilize a range of behavioral, ecological, and genetic/genomic/proteomic techniques to investigate these phenotypes and the processes that underlie their evolution. Currently, we are focusing on using comparative proteomics, RNAi, mating experiments, and natural hybrid zones to identify and functionally test the genes that underlie postmating, prezygotic reproductive isolation between species of cricket - specifically, the Allonemobius socius complex of cricket whose members are only isolated by such phenotypes (see below).


Speciation and the rapid evolution of barriers to fertilization in crickets

cricket


The Allonemobius socius complex of crickets consists of three species that have evolved from a common ancestor over the past 30,000 years. Parental genotypes are maintained within two separate hybrid zones (each involving different species pairs) even though the only barriers to gene exchange appear to be traits related to fertilization (e.g., conspecific sperm precedence and

the ability of males to induce females to lay eggs). Specifically, there are both competitive (conspecific sperm precedence) and non-competitive (a male’s ability to induce a female to lay eggs) gametic isolating barriers between these three species. These gametic isolation phenotypes are associated with species boundaries and evolving rapidly. Our current work is focusing on (1) identifying the molecular basis of these phenotypes, (2) determining how the underlying genes are evolving, and (3) studying/identifying phenotypes associated with male-female sexual conflict.
