Enrichment of reef environments with dissolved inorganic nutrients is considered a major threat to the survival corals living in symbiosis dinoflagellates (Symbiodinium sp.). We argue, however, that direct negative effects on are not necessarily caused by nutrient enrichment itself but phosphorus starvation algal symbionts can be skewed nitrogen (N) (P) ratios. exposed imbalanced N:P ratios long-term experiments and found undersupply phosphate severely disturbed symbiosis, indicated loss...
Abstract Climate change-induced global warming threatens the survival of key ecosystems including shallow water coral reefs. Elevated temperatures can disrupt normal physiological functioning photosynthetic organisms by altering fluidity and permeability chloroplast membranes that is defined regulated their lipid composition. Since habitat-forming reef corals rely on obligatory symbiosis with dinoflagellates family Symbiodiniaceae , heat stress response be expected to strongly influenced...
Reef building corals associated with symbiotic algae (zooxanthellae) can access environmental nutrients from different sources, most significantly via the uptake of dissolved inorganic by algal symbiont and heterotrophic feeding coral host. Climate change is expected to alter nutrient environment in reefs potential benefit or disturb reef resilience. At present, relative importance two major sources not well understood, making predictions responses changes their difficult. Therefore, we have...
The mutualistic cnidarian-dinoflagellate symbiosis underpins the evolutionary success of stony corals and persistence coral reefs. However, a molecular understanding signalling events that lead to successful establishment maintenance this remains unresolved. For example, phosphatidylinositol (PI) pathway has been implicated during multiple parasitic interactions across kingdoms life, yet its role within unexplored. Here, we aimed confirm presence assess specific enzymatic composition PI...
Ocean warming and marine heatwaves induced by climate change are impacting coral reefs globally, leading to bleaching mortality. Yet, resistance resilience not uniform across reef sites corals can show inter- intraspecific variability. To understand changes in health elucidate mechanisms of thermal tolerance, baseline data on the dynamics holobiont performance under non-stressed conditions needed. We monitored seasonal algal symbionts (family Symbiodiniaceae) hosted from a chronically warmed...
Intracellular lipid body (LB) biogenesis depends on the symbiosis between coral hosts and their Symbiodinaceae. Therefore, understanding mechanism(s) behind LB biosynthesis in corals can portentially elucide drivers of cellular regulation during endosymbiosis. This study assessed formation gastrodermal tissue layer hermatypic Euphyllia glabrescens . Diel rhythmicity size distribution was observed; solar irradiation onset at sunrise initiated an increase formation, which continued throughout...
