[email protected] [email protected] Disentangling coral stress and bleaching responses by comparing Spatial and Ecological Niche Partitioning in Congeneric Scorpions gene expression in symbiotic partners Species in the scorpion genus Centruroides Marx, 1890 (Scorpiones: Coral bleaching—the disruption of the symbiosis between a coral Buthidae) are good candidates to study ecological niche partitioning host and its endosymbiotic algae—is associated with environmental due to their habitat plasticity, widespread geographic distribution, stressors. However, the molecular processes are not well understood, and presence of cryptic species. Currently, three species belonging to and no studies have disentangled the transcriptional bleaching three subgroups of Centruroides are distributed along the Isthmus of response from the stress response. In order to characterize general Tehuantepec in southern Mexico, presenting a rare opportunity to stress response, specific stress responses, and the bleaching response, study niche partitioning within a single genus. We examined the we isolated host and symbiont RNA from fragments of Acropora environmental, substrate, and habitat preferences of Centruroides millepora which were exposed to 5 different stress treatments.
