Background
B.Sc. Honours Biology - University of Ottawa
Thesis title: Sexual size dimorphism and diet
specialization in the common map turtle (Graptemys
geographica)
Proposed Research
Teleost fish providing parental care: individual
and intergenerational costs and consequences of
nest predator burden
My PhD research thesis will examine the effects
of nest predator burden on the parental behaviour,
physiology and energy status of a fish that provides
sole paternal care, the smallmouth bass. In addition
to this, I intend to test for intergenerational
consequences of nest predator burden and test
for environmental and genetic effects on offspring
performance and behaviour.
Side Project 1: Effects of barotrauma
on the post-tournament behaviour and survival
of smallmouth bass in Rainy Lake, Ontario
Barotrauma occurs when a fish is rapidly brought
from depth and experiences dramatic changes in
ambient pressure. In the fall of 2006 and 2007
we traveled to Rainy Lake in Northwestern Ontario
to examine the incidence and effects of barotrauma
at a smallmouth bass tournament, as well as the
potential mitigating effects of 'fizzing'. These
projects were done with the financial support
of the Rainy Lake Fisheries Charity Trust.
Side Project 2: Latitudinal variation
in the energetics and physiology of smallmouth
bass parental care
