[[Image:anal secretion2.jpg |thumb|200px|left|Gram stain of anal secretion]] [[Image:paula .jpg |thumb||right|Paula Philbrick]] Burying beetles are thought to control the decomposition of a small carcass by burying, removing hair or feathers, rounding, and applying antimicrobial anal and oral secretions. These secretions, however, are loaded with their own particular microbial community that will proliferate once on the carcass. Working with '''Dr. Paula Philbrick''' (UConn-Waterbury) we are investigating whether burying beetles are manipulating the microbial community to their advantage rather than simply disinfecting the carcass.

There have been three primary approaches to the study of aging: evolutionary ecology asks why and when we senesce, molecular biology examines the cellular mechanisms of aging, and behavioral ecology addresses how aging affects reproductive effort. We are examining how reproductive effort and performance vary with age, and whether all components of reproduction are similarly altered. Burying beetles provide a useful model because alternative hypotheses for improvements with age (more experience and the loss of less fit individuals from the older cohort) can be controlled easily in the laboratory.
