Predation and the risk of predation seem to encourage greater
among individual variation in behavior and correlations among different
behaviors. Other traits, like body shape and coloration, are likely
related to behavior, but how these traits might co-evolve under
predation is not clear. Why do predators seem to encourage greater
variation among individuals in general, and what genes might be
involved?
Predation and the risk of predation are seemingly a major driving
force in shaping animal ‘personalities’ (i.e. shy vs bold behaviours),
body shape (i.e body size, or shape that facilitates escape from
predators) and even body colour (i.e. camouflage from predators). Using
lab populations of fish that have been living and breeding for 3 years
in ponds either without predators, We have preliminary observations that
fish show evolved differences in these traits.
Project details and work involved:
The project will involve measuring behavior (such as activity
levels), body shape and color of individuals from each treatment, and
testing if the presence of predators does indeed favor evolution of
greater variation of these traits. Assessment of demography, size
structure and life history parameters may also be measured. The project
could also involve some limited genetic analyses to identify genes
associated with evolved trait changes.
We are based near Melbourne, Australia. We are a small but tightly
knit group, and have had several French students here in the past that
have enjoyed their stay and interaction with post graduate students
here.
Students for a PhD would apply for a competitive scholarship, usually
helped by having one or more publications. Post-doc applicants would
apply for an Alfred Deakin fellowship. Both are well paid positions
relative to cost of living in Australia.
