Characterizing environmental stress responses of aposymbioticAstrangia poculatato divergent thermal challenges

Abstract: Temperature is an important factor in determining species distribution patterns in ectothermic organisms (Angilleta, 2009). As sea surface temperatures continue to rise, understanding how these changes will affect species distributions demands a broad understanding of organisms' physiological sensitivities to temperature across their native range. There is overwhelming evidence that temperature increases associated with anthropogenic climate change are having widespread ecological consequences on marine species Show more

“…These species tend to have sub-tropical distributions and can be found with extremely low symbiotic densities in the wild, especially at more northern latitudes, in low light environments, or in winter seasons 40 , 41 . Unlike other symbiosis models, such as Aiptasia or the upside-down jellyfish Cassiopea xamachana , facultative corals including Oculina arbuscula (this study) and Astrangia poculata (another emerging model species 42 44 ) calcify just as tropical reef-building corals do (Fig. 1 B).…”

“…Such comparisons have the potential to reveal direct genetic underpinnings and cellular mechanisms of symbiosis, which are challenging to disentangle in systems that exhibit natural variation in symbiotic densities. Future work on this and other facultative coral systems such as Astrangia poculata 44 , 102 or Oculina patagonica 103 , 104 will help elucidate the workings of a canonical and ecologically important endosymbiosis between reef-building corals and their dinoflagellate partners.…”

“…First, NF-κB and TRAF3 are coordinately induced to high levels in the stony elkhorn coral Acropora palmata following acute heat stress 55 ; and in Nv following 2’3’-cGAMP stimulation of the c-Gas-STING pathway 25 . Additionally, TRAF3 has been suggested to play a role in coral heat stress response 56,57 , and has been proposed to be a NF-κB target gene in heat-stressed E. pallida 58 . Therefore, our results provide a dataset to explore new gene network interactions, as well as leading to the identification of unannotated gene transcripts that are involved in the cnidarian immune system, some of which may be previously unknown anti-microbial agents.…”

“…They pull in their tentacles, form a puffed-up ring around their oral disc, do not respond to tactile stimulation, and do not actively feed. During quiescence there are also physiological shifts including lowered coral growth rates (Grace, 2017), polyp loss (Dimond et al ., 2013), and shifts in the coral transcriptome, associated with thermal stress and lowered motility (Wuitchik et al ., 2021). Additionally, the physiological costs of dormancy can last beyond winter into spring (Trumbauer et al , 2021).…”
