*****MS or PhD Opportunity in Animal Behavior and the Evolution of Mate Choice*****

The Dopman Laboratory in the Department of Biology at Tufts University is seeking an MS or PhD student interested in animal behavior, mate choice, and sexual selection. The student will use the European corn borer moth, Ostrinia nubilalis, to investigate how variation in sexual signals and mating preferences affects mate choice, assortative mating, and the evolution of reproductive isolation.

*****Project background*****

Mate choice can shape evolution by determining which individuals reproduce and which combinations of traits and preferences are transmitted to the next generation. Fisherian models of sexual selection predict that mating preferences generate nonrandom mating, creating genetic covariance between sexual traits and preferences and allowing positive feedback in their coevolution. Although this process is well established theoretically, the behavioral steps connecting preference, mating patterns, genetic covariance, and coevolution have been incompletely explored empirically.

The European corn borer provides an unusually tractable system for studying these questions. Females produce alternative sex-pheromone blends, and males differ in their behavioral preferences for those blends. Variation in the female pheromone signal is associated with the locus pgFAR, whereas variation in male preference for the female pheromone is associated with the locus bab. These genes occur on different chromosomes but nevertheless show strong genetic covariance in some natural populations. These findings establish a foundation for studying how individual mating decisions scale up to produce population-level evolutionary change.

*****Graduate research*****

The student will develop an independent project centered on the behavior and evolution of mate choice. Possible questions include:

* How does genetic variation in female signals and male preferences affect sexual selection and assortative mating?

* How consistent are mating preferences across individuals, populations, and environmental conditions?

* How do experience, social context, or population composition alter mate choice?

* How do climate, artificial light, air pollution, host plants, or natural enemies affect pheromone communication?

* Does sexual selection act more strongly on female signals, male preferences, or both?

* How do sexual selection and genetic drift interact to maintain—or eliminate—variation in female signals and male preferences within populations?

* How does divergence in mate choice contribute to reproductive isolation between populations?

Research may involve controlled behavioral assays, population-cage experiments, pheromone manipulations, insect rearing, field experiments, and quantitative analysis of behavior. Genetic or genomic approaches may be incorporated to connect behavioral variation with the underlying signal and preference loci, but prior molecular experience is not required. The precise direction of the project will be developed collaboratively based on the student’s interests.

*****Desired qualifications*****

Applicants must have a strong interest in animal behavior and mate choice. Students interested in behavioral ecology, sexual selection, animal communication, sensory ecology, evolutionary biology, or entomology are especially encouraged to apply.

Previous experience with behavioral experiments, insect husbandry, field biology, experimental design, video or observational data, or statistical analysis would be helpful. More important are curiosity about animal behavior, careful observational skills, patience with experimental work, and enthusiasm for developing independent research questions. Students must also have an ability to work with others and a strong sense of humor, both of which are needed to make science fun and worthwhile.

*****Research environment*****

The Dopman Laboratory combines behavioral experiments with genetic, genomic, and evolutionary approaches to understand how ecological and behavioral differences arise. The student will join the Department of Biology at Tufts University in Medford, Massachusetts.

*****How to apply*****

The Tarwater Lab at the University of Wyoming seeks a highly motivated and curious Ph.D. student to study tropical birds in Panama, ideally starting Fall 2027. The student may address questions in behavior, demography, or species interactions. Projects can build on ongoing work on army ant swarms, mixed-species flocks, plant-disperser interactions, population declines, and multi-taxon interactions among birds, bats, fruits, and insects. Projects may examine environmental variation across space, using Panama’s precipitation gradient, or through time, using long-term data from a single site. A key strength of this position is access to datasets already collected in Panama. The student will divide their time between collecting new field data and analyzing existing data, allowing them to start publishing early while developing their own fieldwork. The student will have flexibility to shape the focus of their dissertation within these themes. Successful applicants will be expected to contribute to a collaborative team, present results at professional conferences, publish results in peer-reviewed journals in a timely manner, and assist with grant proposals. Support is provided through a combination of Research Assistantship and Teaching Assistantships, which include a living wage, tuition, and benefits.

Qualifications: Candidates must possess a B.S. or M.S. degree in biology, wildlife ecology, natural resource management, or a related field. Ideal candidates would have 1+ years of field experience, including experience in the mist-netting of birds, and some experience in analyses and writing manuscripts.
