Lateralization in
Predator-Prey Interactions
A study from a population of Threespine Stickleback (
Gasterosteus aculeatus) in Drizzle Lake, QCI.
Joanna Preston, Directed Studies
The population
of Threespine Stickleback in Drizzle Lake exhibit high frequencies of morphological
asymmetries, yet predation rates by avian and fish piscivores are also high.
I am quantifying
bilateral symmetry of predator-induced injuries by avian piscivores of samples
of injured and dead stickleback to determine if behavioural asymmetry is
involved in predator-prey interactions.
Morphometrics
were completed on these samples as well as a random sample of uninjured stickleback
to determine if morphological asymmetries are a function of behavioural asymmetry.
