In this indaba Dr Celia Schunter (https://www.celiaschunter.com, @celiaschunter), a Molecular Ecologist, takes us through her research into the effects of increased CO2 prevalence in fish. Dr Schunter elaborates on her ways of reverse engineering the genome, transcriptome, proteome - finding that needle in the haystack. We dip into strategies and approach changes that would better harmonize our interactions with the natural world.
