Key research
- In collaboration with Rick Mayden (University of St Louis), Francois
Chapleau (University of Ottowa), Kevin Roe (University of Mississippi)
and Claude Renaud (Canadian Museum of Nature), used cladistic analyses
of morphological data to construct a phylogeny of the living lampreys.
Molecular data will subsequently be incorporated with the morphological
information to produce a phylogeny based on total evidence.
- Pippa Milton and Howard Gill – Use of both sequence
and gene order mitochondrial DNA data to clarify more precisely the relationships
between the two southern hemisphere and single northern hemisphere families.
- In collaboration with Associate Professor Shaun Collin (University
of Queensland), elucidating aspects of the evolution of colour vision
in vertebrates.
- Karen Marshall and Max Cake – Investigation of the
carbohydrate and lipid metabolism of the lamprey Geotria australis
during their upstream migrations, during which it does not feed. An understanding
of the ways in which ovarian development is facilitated during the extended
non-feeding stage of lampreys.
