We use Lepidoptera as a test system to explore how environmental variation affects mating and foraging behavior, life history traits, population structure and dynamics, and plant-insect interactions over ecological and evolutionary time.

My research group is focused on the future course of extinction; on resulting
changes in community composition and interactions, and in the delivery of ecosystem services; and on realizing novel opportunities for conservation in agricultural landscapes.

My main lines of research are the ecology of species interactions and biodiversity conservation science. In species interactions I am concerned with the evolution of plant anti-herbivore traits, seed predation, pollination and dispersal. Work on conservation biology is aimed at complementing the traditional interests of the conservation of taxa with the increasingly needed conservation of ecological processes. Most of my tropical work is carried out in Mexico, Central Amazonia and California.

We study morphologic, genetic, population and community responses to the last several thousand years of climatic change in vertebrate ecosystems of temperate North and South America, most recently, peninsular India.

I am investigating the processes and interactions shaping coastal marine communities, and incorporating this understanding in the management and conservation of marine ecosystems.

We work on the application of molecular techniques to ecological and conservation questions in marine systems.  Current projects focus on historical population size of whales, dispersal patterns of the larvae of marine invertebrates, quantifying adaptive evolution along an environmental gradient in Strongylocentrotus purpuratus using high density oligo array technology, identifying traits in coral symbionts that may allow adaptation to increasing ocean temperatures, exploring the genomic basis for differences in sperm morphology in Strongylocentrotus purpuratus, describing the ecological correlates of gene flow along the western coast of the United States, and the effects of fishing pressure on marine population structure.

The Petrov group is interested in a wide range of questions in molecular evolution and molecular population genetics.
One key line of research is focused on understanding molecular adaptation. How frequent is adaptation? Does it generally involve mutations of small or large phenotypic effect? Does it tend to involve new mutations or use the standing variation? Are adaptive mutations typically coding or regulatory? How frequent is population-specific versus whole-species adaptations? What effect does recurrent adaptation has on patterns of neutral variation? We carry out whole genome analyses using newly developed methodology to generate putative general answers to these questions and also attempt to verify these putative answers with studies of individual test cases. As part of this research program we are investigating patterns of current adaptation that many organisms are undergoing in response to anthropogenic changes in the environment.
The second major focus is on the evolution of genomes. Why are some genomes small and others large in the sheer amount of DNA? What determined the numbers and kinds of genes found in different genomes? Chromosomal numbers? How do multigene families come to be and maintain their sizes? What role does horizontal gene transfer have on genome evolution? Mutational biases? Natural selection?

We presently study the evolution of social behavior and mutualism, emphasizing the role of cooperation, and using cooperative game theory. We are working on the ``social selection project'' to develop alternatives to sexual selection theory and its corollaries. Previous work in the lab has also investigated the evolutionary community ecology of Caribbean Anolis lizards, the role of coupled oceanic and benthic processes in the population dynamics of intertidal invertebrates, and the theory of ecological economics.

I seek to understand the biogeochemical cycles of nitrogen, phosphorus, and other elements, on scales from local ecosystems to global.  My lab's research uses the Hawaiian Islands as a model system in which we can identify and elucidate the mechanisms controlling biogeochemical cycles - including human modifications of those cycles, and their ecological consequences.  Recent work has focused on human-environment interactions in Hawaiian agriculture prior to European contact.

Developing evolutionary theory from mechanistic viewpoints. Using techniques ranging from biochemistry, DNA sequencing, and wind-tunnel flight biophysics to field ecology and mathematical population genetics, we study biochemical and physiological mechanisms of genetic variation, ecological niche structure as the source of natural-selective pressures, and the resulting patterns of evolution of metabolic organization.
