To quantify how coral reef invertebrates will cope under future climate conditions, its necessary to understand the mechanisms that underpin acclimatisation to ocean warming and ocean acidification. by identifying these molecular mechanisms, we will gain a better understanding of the adaptive capacity of coral reef organisms. The model sponge species Ircinia ramosa, was exposed to varying temperature and pCO2 stress based on current, and forecasted 2050 and 2100 environmental conditions within the National Sea-simulator at AIMS to determine their capacity to acquire tolerance to future climate conditions. As a part of this experiment, metatranscriptome data was collected from sponges exposed to future climate conditions and is presented within this Bioproject.
