Our Behavioral Ecophysics lab focuses on the study of organismal mechanisms (e.g., physiology, biomechanics) in light of biotic and abiotic interactions, with the goal of establishing explicit links between physical laws and rules of life, from individual to ecological scales. A central challenge of biological studies is to describe functional links between underlying architecture (e.g., genotype, phenotype) and emergent phenomena (e.g., performance, ecological patterns).

Viruses have been recognized as abundant but virtually unknown members of the soil microbiome. Here we will explore early results in the burgeoning field of soil viral community ecology as we begin to understand viral diversity, biogeography, and impacts on microbial ecology and biogeochemical cycling in terrestrial ecosystems.

Social mating systems describe the socio-spatial relationship between members of the opposite sex for reproduction. While entire avian lineages are predisposed to particular social mating systems by traits that evolved millions of years ago, present ecological conditions facilitate differences in social mating systems between closely related species or between populations of the same species. Hence, the study of geographic variation of social mating systems can shed new light on our understanding of how ecological variables shape extant mating associations.

Inclusive fitness theory is a widely invoked mechanism for explaining the evolution of altruistic workers in insect societies. Inclusive fitness is the sum of direct and indirect fitness components. In testing this theory, however, the indirect component of inclusive fitness has received much attention while the direct component has been rather neglected. This is especially inappropriate for primitively eusocial species where workers are often potentially capable of direct reproduction.

Many animals are highly visual. They view their world through photoreceptors sensitive to different wavelengths of light. Animal survival and optimal behavioral performance may select for varying photoreceptor sensitivities depending on animal habitat or visual tasks. Our goal is to understand what drives visual diversity from both an evolutionary and molecular perspective. The group of more than 2000 cichlid fish species are an ideal system for examining such diversity. Cichlid are a colorful group of fresh water fishes.

A fundamental source of conflict in viviparous organisms stems from differences between maternal and paternal interests in resource allocation to offspring (i.e. parental conflict). Under parental conflict, variance in paternity drives the evolution of paternally derived, resource-acquiring alleles, and maternally derived alleles that distribute resources equally among offspring. In hybrids, mismatches between these parent-of-origin effect alleles can cause inappropriate development of essential nutritive tissues (e.g.

The coexistence of multiple species competing for a finite set of resources is a widely debated topic in community ecology. Species with strongly overlapping niches are expected to drive each other towards exclusion, but such species may also coexist if they have similar competitive abilities. This compromise can lead to a peculiar pattern of clumped coexistence, where multiple species share similar niches, leaving gaps open in the theoretically available niche space.
