While tropical species and populations exhibit high sensitivity and negative impacts of acute ocean warming, with development and cross-generational warming experience acclimation can occur. One reason why beneficial plasticity to environmental change does not always happen is due to the expected costs of making phenotypic changes. In laboratory experiments fish are generally fed to satiation and therefore have ample energy to produce phenotypic changes. This research explores whether reducing food resources to the current generation influences whether and how thermal plasticity occurs. This research found that food availably interacts with developmental thermal conditions, as the effect of food was greatest at elevated temperatures. Additionally, when grandparental fish experience warming the negative effects of developmental warming and low food were reduced, indicating that transgenerational plasticity still occurs in limited resource conditions.
