Decorated cricket courtship behaviour: my Honours dissertation

Last year I completed my Honours Dissertation with Dr Luc Bussiére as supervisor.

Different animals expend the energy they have adopting strategies dependent on many variables. Sexual signalling is usually a very expensive trait, and so it is one of the most interesting to study. I am investigating the reasons behind a declining pattern in calling effort of decorated crickets (Gryllodes sigillatus) observed throughout a week of energy manipulation, relating it to specific levels of past activity and quality of available mates. This research of mine involved males’ diet manipulations, male calling effort recording, energy and mating history manipulations and finally behavioural trials.

Hopefully the results of my study will soon be published!
