Carr Lab, Memorial
University of Newfoundland
I am interested in
patterns and processes of molecular
phylogeography and evolution within and among species and
natural populations of vertebrate animals, and novel genomic biotechnology
approaches to these questions. My investigations include:
(1) Mitogenomic
Phylogeography of the pre- & post-glacial Nearctic &
North Atlantic, including Atlantic Cod, Wolffish, Harp Seals,
and Newfoundland Caribou
(2) Genomic diversity &
origins of ancient and modern peoples of Newfoundland
(3) Phylogeography of "Species At Risk" of
extinction, including the occasional "sea monster"
For further details and other
projects, please see the PDF MSS below, and (or) contact
Steve at scarr@mun.ca.
My laboratory has
taken a mitogenomic approach to the interrelated problems
of evolutionary and population genetics and systematic biology.
Analyses based on complete maternally-inherited mitochondrial
DNA genomes provide well-resolved, highly-corroborated
molecular phylogenies within and among species that can generate
and test hypotheses about morphological, biogeographic, and
behavioral evolution. Phylogeographic analysis
[the analysis of genetic relationships in their geographic
context] of completely-resolved intraspecific gene trees, based on
full-length mtDNA genomes,
provides the detailed historical information and necessary
statistical power to evaluate vicariance and dispersal phenomena
at scales of interest to fisheries managers and population
biologists. I have combined this with novel analytical methods,
including a Monte Carlo simulation test of population
structure, and a non-parametric Kolmogorov-Smirnoff test
of coalescent offsets.
I am
cross-appointed to the Department of Computer Science,
where my interests are in Computational Biology of DNA
sequences and Next-Generation DNA data
signal analysis.
