Investigating the photosynthesis of Symbiodinium in Caribbean gorgonian corals
Symbiodinium photosynthesis fuels the growth of an array of marine invertebrates, including scleractinian corals and octocorals. Studies examining the symbiosis between Caribbean octocorals and Symbiodinium are sparse, even though octocorals blanket the landscape of Caribbean coral reefs. Here, I …

Small RNA studies in Drosophila melanogaster, Stylophora pistillata and Symbiodinium sp.
… (a species of coral found in the Red Sea) and Symbiodinium sp. (a photosynthetic, symbiotic algae present in the coral cell), my collaborators and I strived to study the genome, transcriptome and proteome of both organisms. At present, there is another coral genome available — from Acropora …

Biochemical Composition of Caribbean Gorgonian Corals and Their Symbiosis Under Ambeint and Stressful Conditions
… eight gorgonian species hosted different clade B Symbiodinium, and in two gorgonian species in which the bacterial microbiomes were investigated, two distinct communities were found. In the eight gorgonian species, skeletal content varied from 75-96%, with those having more tissue also having more …

Mixing it up: Multiple symbiont acquisition strategies as an adaptive mechanism in the coral Stylophora pistillata
… acquisition. The algal symbionts (<italic>Symbiodinium</italic>) present in <italic>S. pistillata</italic> adults, juveniles, and larvae (planulae) were identified using denaturing-gradient gel electrophoresis (DGGE) and real-time PCR. DGGE confirmed previous reports that in the Gulf of …

Assessing the photosynthetic impact of inorganic carbon in symbiotic dinoflagellates in culture and in coral host complexes
… pH on the photosynthesis of the symbiotic algae Symbiodinium sp. both in vitro and in hospite. While it has been speculated that increased carbon dioxide may stimulate primary production, results presented here for short-term incubations show that Symbiodinium sp. photosynthesis is saturated at …

Assessing the risk of ocean acidification for scleractinian corals on the Great Barrier Reef
… experimental conditions in studies that observed Symbiodinium dysfunction and productivity loss. Chapter 2 presents a working hypothesis to describe the fundamental physiological aspects of coral bleaching under ocean acidification. This research investigates the response of Acropora aspera using …

HISTOLOGICAL RESPONSES OF THE SEA ANEMONE A. PALLIDA TO BLEACHING INDUCING STRESSES
… corals and unicellular algae of the genus Symbiodinium that provide them with photosynthesis-derived carbon. Unfortunately, with the climatic upheaval that we witness today, the long-term survival of coral reefs could be in jeopardy. Massive loss of symbiotic algae, a phenomenon known as …

The role of thermal history in shaping the microbiome of Red Sea corals
… compared to the central/southern Red Sea. Symbiodinium clade type (ITS2) and microbial community (16S rRNA metagenomics) associated with six key coral species persisting across five sites of the northern Red Sea (29°-20°N) were then examined. Symbiodinium clade identity associated with each …

Production of Dimethyl Sulphide (DMS) by Scleractinian Coral during Aerial Exposure – Effect of Temperature and Light
… in DMS production were not driven by changes in Symbiodinium physiology. The results of this study show that coral reefs exposed regularly at low tide can potentially act as significant contributors to the local DMS-flux. However, interspecific differences in response, as well as the effects of …

Characterisation of Nitric Oxide Synthase Activity in the Sea Anemone Aiptasia pallida and an Evaluation of Responses to Environmental Stress
… in the zooxanthellae associated with A. pallida, Symbiodinium spp. and in five scleractinian coral species. Preliminary studies were conducted to characterise NOS from A. pallida. NOS activity of this species was shown to be predominantly cytosolic and basal rates of enzyme activity were …

Ecofisiologia e resiliência do coral recifal zooxantelado siderastrea stellata verril 1868 em face às diferentes pressões ambientais
… demonstrou uma alta fidelidade em associação com Symbiodinium clado C predominantemente. Apesar disso, levantamos a hipótese de que essa associação pode ser resultado de mudanças nas populações do clado B devido a eventos estressantes. Desta maneira, a partir das discussões realizadas neste …

Phylogeography of Oculina Corals and their Algal Symbionts: Insights into the Origin and Expansion of Oculina Patagonica in the Mediterranean
In a world of rapidly changing environmental conditions, species must effectively respond to their changing habitat or risk extinction. The goal of my dissertation is to elucidate the origins and mechanisms underlying the recent successful population expansion of the invasive coral Oculina …
