Giant clams are important ecosystem engineers of coral reefs because they harbor large quantities of phototrophic Symbiodiniaceae dinoflagellates of mainly genera Symbiodinium, Cladocopium, and Durusdinium.

Mitigating the seductive details effect by topic and irrelevance signals
Abstract Background Seductive details (interesting digressions in learning materials) are often integrated into learning units to make them more appealing to learners. However, studies indicate that this tends to overload students cognitively and impairs their learning performance. Aims The present study investigated whether these negative consequences

Symbiodinium—Invertebrate Symbioses and the Role of Metabolomics
Symbioses play an important role within the marine environment. Among the most well known of these symbioses is that between coral and the photosynthetic dinoflagellate, Symbiodinium spp. Understanding the metabolic relationships between the host and the

Examining Marine Assemblages Across an Inverse Salinity Gradient
ABSTRACT Salinity gradients and fluctuations can create a natural ecological filter, with few species tolerating salinity above 50 practical salinity units (PSUs). We investigated how an inverse salinity gradient affected marine community diversity and composition in Shark Bay, a remote hypersaline coastal embayment in Western Australia.

The Ecological Mechanism of Coral–Algal Phase Shifts: A Case Study of Wenchang in Hainan Province
This study selected the coral reef areas in the coastal waters of Wenchang, Hainan, China, which were significantly affected by human activities. Through four consecutive years of field investigations, the key driving factors and potential mechanisms of ecological phase shifts between corals and macroalgae were identified, thus providing a scientific ...

A hypothesis linking sub-optimal seawater pCO2 conditions for cnidarian-Symbiodinium symbioses with the exceedence of the interglacial threshold (>260 ppmv) [PDF]
Most scleractinian corals and many other cnidarians host intracellular photosynthetic dinoflagellate symbionts ("zooxanthellae"). The zooxanthellae contribute to host metabolism and skeletogenesis to such an extent that this symbiosis is well recognised ...

Some hermatypic corals spawn eggs that contain zooxanthellae. We followed development of zooxanthella-containing eggs of two such species, Pocillopora verrucosa and P. eydouxi. We also documented changes in the distribution pattern of zooxanthellae during development. Oocytes of both species took up zooxanthellae 3 to 4 days before spawning.

Microbial invasion of the Caribbean by an Indo-Pacific coral zooxanthella [PDF]
SignificanceThis research documents the spread of an opportunistic coral endosymbiont,Symbiodinium trenchii, from the Indo-Pacific into the Greater Caribbean, a region afflicted by human-related impacts including climate warming and environmental degradation.

Engineering Strategies to Decode and Enhance the Genomes of Coral Symbionts
Elevated sea surface temperatures from a severe and prolonged El Niño event (2014–2016) fueled by climate change have resulted in mass coral bleaching (loss of dinoflagellate photosymbionts, Symbiodinium spp., from coral tissues) and subsequent coral ...

ASSIMILATION OF PHOTOSYNTHETIC PRODUCTS OF ZOOXANTHELLAE BY A REEF CORAL
1. The hermatypic coral, Pocillopora damicornis was incubated in the laboratory and in its reef habitat with Na214CO3 for 1-24 hours. Controls were incubated in darkness. 14C fixation in light exceeded that in darkness. 2. Fractionation of corals labeled on the reef for 24 hours revealed that 35-50% of the total 14C fixed appeared in the animal tissue ...
