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.
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.
