19 November 2020. We are happy to announce that the Journal of Experimental Biology just published the latest paper on CO2 effects in the early life stages of Atlantic silversides! For her PhD research at Stony Brook University, Teresa meticulously measured oxygen consumption in developing silverside embryos and newly hatched larvae exposed to contrasting oxygen and CO2 conditions throughout multiple experiments in 2017 and 2018. Her work shows that the metabolism of embryos but not larvae is sensitive to elevated CO2 conditions, leading to higher metabolic rates at normoxic levels, but reduced metabolic rates under low oxygen conditions, compared to controls. These basic empirical data confirm the emerging picture that CO2 effects in marine fish manifest largely if at all during early ontogeny, i.e., during the embryo stages. Well done, Teresa, and congratulations to your first lead-author paper!
