Potential Trade‐Off Between Temperature and Tissue Loss Resistance in Corals Associating With Algal Symbionts in the Genus DurusdiniumNARA Subscribed
The symbioses between corals and microorganisms, including the endosymbiotic dinoflagellates (family Symbiodiniaceae) and bacteria, are central to coral health and functioning. Certain species of Symbiodiniaceae in the genus Durusdinium are known to confer enhanced thermotolerance to corals and could therefore be beneficial under global climate change. However, association with thermotolerant algal symbionts may come with trad...
Enhancing Interest and Confidence of Students in Research Through a Cross-Disciplinary Undergraduate-Initiated Medical Research ProgramNARA Subscribed
Introduction Incorporating research activities into the undergraduate curriculum of medical and biomedical engineering studies is essential to nurture research talents and bring about future innovations. However, students may not understand the relevance of conducting research to their future career during undergraduate studies, as it involves little clinical-related work and takes time away from their hectic schedule. In addi...
Skeletal morphometrics suggests high fitness of hybrid coral recruits under ocean warming and acidificationNARA Subscribed
Anthropogenic greenhouse gas emissions increase sea surface temperature and acidification, inhibiting calcification of reef-building corals. While ocean acidification is known to hinder skeletal development of newly settled coral recruits, little is known of its effects on older purebred or interspecific hybrid recruits, or its combined effects with temperature. Using 3D X-ray microscopy, we found that predicted mid-century oc...
Heat‐Evolved Microalgae (Symbiodiniaceae) Are Stable Symbionts and Influence Thermal Tolerance of the Sea Anemone Exaiptasia diaphanaNARA Subscribed
Symbiotic cnidarians, such as sea anemones and corals, rely on their mutualistic microalgal partners (Symbiodiniaceae) for survival. Marine heatwaves can disrupt this partnership, and it has been proposed that introducing experimentally evolved, heat‐tolerant algal symbionts could enhance host thermotolerance. To test this hypothesis, the sea anemone Exaiptasia diaphana (a coral model) was inoculated with either the heterologo...
Heat‐evolved algal symbionts enhance bleaching tolerance of adult corals without trade‐off against growthNARA Subscribed
Ocean warming has caused coral mass bleaching and mortality worldwide and the persistence of symbiotic reef‐building corals requires rapid acclimation or adaptation. Experimental evolution of the coral's microalgal symbionts followed by their introduction into coral is one potential method to enhance coral thermotolerance. Heat‐evolved microalgal symbionts of the generalist species, Cladocopium proliferum (strain SS8), were ex...
Adaptive responses of free‐living and symbiotic microalgae to simulated future ocean conditionsNARA Subscribed
Marine microalgae are a diverse group of microscopic eukaryotic and prokaryotic organisms capable of photosynthesis. They are important primary producers and carbon sinks but their physiology and persistence are severely affected by global climate change. Powerful experimental evolution technologies are being used to examine the potential of microalgae to respond adaptively to current and predicted future conditions, as well a...
Maternal effects have been well documented for offspring morphology and life history traits in plants and terrestrial animals, yet little is known about maternal effects in corals. Further, few studies have explored maternal effects in gene expression. In a previous study, F1 interspecific hybrid and purebred larvae of the coral species Acropora tenuis and Acropora loripes were settled and exposed to ambient or elevated temper...
The roles of age, parentage and environment on bacterial and algal endosymbiont communities in Acropora coralsNARA Subscribed
The bacterial and microalgal endosymbiont ( Symbiodiniaceae spp.) communities associated with corals have important roles in their health and resilience, yet little is known about the factors driving their succession during early coral life stages. Using 16S rRNA gene and ITS2 metabarcoding, we compared these communities in four Acropora coral species and their hybrids obtained from two laboratory crosses ( Acropora tenuis × A...
