Purple sea urchin larvae alter their transcriptome in response to ocean acidification

ABSTRACT: In this research we present a transcriptomics analysis of the physiological response of a marine calcifier, Strongylocentrotus purpuratus, to ocean acidification, a decline in ocean pH that results from the absorption of anthropogenic carbon dioxide (CO2). Larvae were raised from fertilization to prism stage in seawater with elevated CO2 conditions based upon IPCC emissions scenario B1 (540ppm CO2) and A1FI (1020ppm CO2). Adult S. purpuratus were collected using SCUBA from Goleta Pier (Goleta,CA, USA) and maintained in flowing seawater tables at 15-16°C. Spawning was induced by coelomic injection of 0.5M KCl following standard methods (Strathmann 1987). Eggs were collected from 3 females and separately fertilized by sperm from a single male (i.e. all larvae were full or half-siblings). Eac
