Paul Bartell Lab
Research in the Paul Bartell laboratory focuses on the regulation of biological clocks in birds at the systems level. We use behavioral, molecular, and electrophysiological techniques to understand the neural and endocrine mechanisms by which these daily clocks and yearly calendars control the temporal organization of behaviors and life history stages. Current projects are broadly focused along two categories:
- We (and others)
have determined that biological clocks temporally organize pre-migratory
and migratory behaviors. Currently, we seek to identify the changes in
protein and gene expression that allows normally diurnal birds to become
nocturnally active during migration, yet still function at a high
performance level despite having very little sleep.
- The influence of
biological clocks in timing reproduction has been established, yet the
proximal mechanisms by which they do so have remained elusive.
