RESEARCH INTERESTS

 

I am interested in the behavior and evolutionary ecology of insects and their populations.  My projects typically involve the development of a theoretical framework (based upon biological/evolutionary principles) to derive testable hypotheses.  These hypotheses are then subject to investigation in the field and/or laboratory.  Using this approach I have studied avariety of topics which include: insect-mediated pollination in slickspot peppergrass, seed predation on slickspot peppergrass by harvester ants, predator-prey relationships between crab spiders and insects, host choice decisions in bark beetles, and the function and duration of parental care in subsocial insects.

GRADUATE STUDENT OPPORTUNITIES
 

I have several ongoing projects in the area of pollination biology and seed predation in slickspot peppergrass, a rare mustard endemic to southwestern Idaho.  I am also open to considering other projects involving insect ecology and behavior.  Please contact me for updates on research opportunities and the availability of teaching assistantships.

CURRENT & FUTURE PROJECTS

 
  1. Interactions between insects and slickspot peppergrass (Lepidium papilliferum), a rare mustard endemic to southwest Idaho. Research topics include insect-mediated pollination, seed predation by harvester ants, herbivory, and predator-prey interactions between crab spiders and the insects that pollinate L. papilliferum flowers.

  2. Mating system and population genetics of slickspot peppergrass.
    -
    the importance of outcrossing to fruit set in slickspot peppergrass
    -population genetics of slickspot peppergrass (collaboration with Drs. S. Novak and J. Smith)


  3. Host choice decisions in bark beetles (Scolytinae).  Some bark beetles are a serious threat to the health of forests throughout North America because of their ability to mass colonize and kill healthy trees.  I am interested in developing a general understanding of host choice decisions in bark beetles, as well as exploring the link between the individual host choice decisions and the dynamics of mass colonization on host trees.  A part of this research involves looking at the effects of flight on fat utilization and its consequences for host choice decisions.
