Fluorescence in reef corals
… systems. Prior measurements from Caribbean corals identified five fluorescing pigments in reef corals. In this thesis I study coral fluorescence spectra. I wanted to learn if fluorescence could be useful for large scale mapping and monitoring of the reef as a part of an effort to stop the …

Ordovician corals of the Williston Basin periphery
<p> Tabulate and rugose corals are described from the Ordovician Red River) Stony Mountain, and Stonewall Formations in southern Manitoba and the Ordovician Bighorn Formation in northern Wyoming. Fifty-four species, 12 of which are new, are distributed in 20 genera. The Flower Model of coral …

Microbial Communities of Healthy and Diseased Corals
The extent of phenotypic plasticity in the corallite morphology of colonies of M. annularis s.s. was determined by analyzing the three-dimensional morphology of calical surfaces and the two-dimensional corallite morphology as represented in transverse thin sections. Significant phenotypic …

Tropical stony corals host diverse microbial nitrogen dynamics
… (N) fixation has been well quantified in corals in accounting for the source of their fixed N, but no complementary loss term had been directly detected. This pathway is important for understanding sources and sinks of nitrogen on reefs and how they may impact coral success. Here we use …

Taxonomy and ecology of South African reef corals
… of South African hermatypic Scleractinian reef corals, a description of coral communities on northern Natal coral reefs, experiments isolating the influence of the most important abiotic factors forcing these communities and finally management suggestions for the marine reserves within which …

The Environmental Sensitivity of Cold-water Corals Lophelia pertusa
… and cuttings (discharges). In addition, live corals were exposed to 4-h sedimentation events of increasing rates and polyp behaviour analysed. Sediment removal mechanisms were also examined. Finally, skeletal characteristics and trace<br/>metal concentrations were measured in skeletons sampled …

Investigating the photosynthesis of Symbiodinium in Caribbean gorgonian corals
… 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 compared the photosynthetic characteristics of …

The mineralogy and chemistry of modern shallow-water and deep-sea corals
… conflicting predictions about the fate of corals under OA. Rather than investigating the mechanism directly, I use a mineralogical approach to study the aragonite end-products of coral biomineralization. I hypothesize that coral mineralogy and crystallography will lend insights into how …

Cellular and molecular characterisation of regeneration in calcareous sponges and soft corals
… investigates the regenerative capacities of soft corals from the genus Xenia and calcareous sponges from the genus Sycon. Cnidarians, which include corals, sea anemone, and jellyfish, are renowned for their remarkable regenerative abilities. Occupying a key phylogenetic position as the sister …
