Abstract
Developmental plasticity can play an important role in marine invertebrate thermal tolerance. To understand the genomic basis of this observation, we characterized the transcriptomic response to elevated developmental temperature and subsequent acute exposure to two higher temperatures using the copepod Acartia tonsa. We observed massive baseline gene expression differences between developmental treatment groups, however following acute exposure we observed a largely shared transcriptomic response. We found that genes involved in mitochondrial function were associated with variation in a thermal tolerance trait. These results suggest that differences in developmental temperature drive differences in gene expression that underlie variation in thermal tolerance.
