RESEARCH
INTERESTS
My
M .Sc. research involved using physiological information to address
ecological questions concerning the migration of the Western Sandpiper
(Calidris mauri). Westerns migrate from their breeding grounds
in the arctic to their wintering grounds in Latin America and southern
California. It takes them weeks to make this trip as they "hop"
from site to site, stopping along the way for some R&R and to eat
in order to restore fat reserves for the remaining trip. The overall
goal of my project was to use physiological data to evaluate and compare
several of these migratory stopover sites throughout the Georgia Basin
in Washington State and BC
In evaluating these sites, the ultimate expression of site quality in
the western sandpiper is fat deposition. If a site allows individuals
to obtain a high rate of fattening, it is allowing the birds to achieve
their ultimate goal better than a site at which the birds are not able
to fatten. Previous studies have focused on mass to evaluate condition
at these sites; however this only gives us a snapshot of one moment
in time. If two populations have equal mean mass but one population
is gaining and the other is losing, the conditions of the two populations
differ considerably while the mass data alone would not detect this.
