Abstract

This thesis looks at the effects of macronutrients and micronutrients on different life history traits in the Australian field cricket, Teleogryllus oceanicus. It shows that different macronutrients are not simply calories to be allocated to different traits, but directly determine the expression of different life history traits and mediate their trade-offs. Moreover, specific nutrients affect the relative abundances of different bacterial species in the cricket's gut and impact gut microbial diversity. As a result, the bacterial gene pool and its metabolic capabilities are altered by diet, with the potential to change the interaction between the gut microbiome and its host.
