AbstractAdult organisms may “prime” their offspring for environmental change through a number of genetic and non-genetic mechanisms, termed parental effects. Some coral species can alter their thermal tolerance by shuffling the proportions of Symbiodinium types within their endosymbiotic communities, but it is unclear if this plasticity can be transferred to offspring in corals that have maternal symbiont transmission. We evaluated symbiont community composition in tagged colonies of Montipora digitata from Orpheus Island, Australia, over two successive annual spawning seasons, the second of which overlapped with the 2016 mass coral bleaching event on the Great Barrier Reef. We applied amplicon sequencing of the ITS2 locus to samples of four families (parent colonies and 10-12 eggs per family) to characterize their potential for symbiont shuffling and to determine if shuffled abundances were preserved in gametes. Symbiont cell densities and photochemical efficiencies of the symbionts’ photosystem II differed significantly among adults in 2016, suggesting differential responses to increased temperatures. Although abundances of the dominant symbiont haplotype, a representative of clade C15, did not differ among families or over time, low-abundance (“background”) ITS2 types differed more among years (2015 vs. 2016) than between life stages (parent vs. offspring). Results indicate that background symbiont shuffling can occur in a canonically ‘stable’ symbiosis, and that such plastic changes to the symbiont community are heritable. To our knowledge, this is the first evidence that shuffled Symbiodinium communities can be inherited by early life-history stages and supports the hypothesis that plastic changes in microbial communities may serve as a mechanism of rapid coral acclimation to changing environmental conditions.

Mass Bleaching

Symbiotic single-celled dinoflagellates play critical roles in providing corals with both energy and tolerances to survive over a range of environmental conditions. Stressors can cause the breakdown of this symbiosis, resulting in mass bleaching events, and are projected to increase in frequency and spatial extent, threatening the long-term survival of coral reefs. Recent studies have identified symbiont shuffling in corals towards more thermo-tolerant clades as a functional tool for their surviving thermally-induced stress events. However, this was not observed within Pocillopora damicornis colonies tracked over a complete bleaching to recovery cycle during the 2014 mass coral bleaching event in Hawai‘i. Instead, previously acquired symbiont clades were maintained following bleaching recovery. This observation suggests additional factors may be involved in thermal-stress acclimation and adaptation in this coral.
