One of the main focus of coral reef ecology has been to shed light on the importance of all microbial members of coral holobiont and how their interactions contribute to the coral’s resilience. However, knowledge is lacking about the composition of microbial communities inhabiting the surface mucus layer of corals including Fungia fungites, a species that lives under stressful conditions close to fish farms in Vietnam. I investigated the prokaryotic communities that are thriving in Fungia fungit...

石珊瑚是具有自營及異營功能的生物，近年來，異營功能被認為是石珊瑚很重要的營養來源，可令牠們從珊瑚白化中復原。香港每年的海水溫度可由冬天的攝氏十三度升到夏天的三十度，這季節性的溫度變異令香港成為石珊瑚生存的邊緣地方，石珊瑚只能組成群落但不能成礁。雖然環境因素對於石珊瑚的生長並不理想，但大型的珊瑚白化仍沒有發生，這意味著香港的珊瑚比較能夠適應香港的嚴峻困難環境，珊瑚具有的異營功能或許能夠提供牠們額外的能量，作為日常新陳代謝之用。所以，這研究的目標是找出異營功能對香港石珊瑚的重要性，這研究以豐年蝦的無節幼體(Artemia salina nauplii)及團塊角孔珊瑚(Goniopora lobata)作為實驗對象，以找出石珊瑚怎樣應用異營功能來加快生長、提高生理反應及增加能量儲備。此外，這研究還成立了一種量化珊瑚白化的方法，以提供一種簡單、快捷、客觀及不破壞珊瑚為前提的方法來監測珊瑚的健康。 / 本研究紀錄了七種香港常見但具有不同珊瑚蟲大小的石珊瑚的攝食速率，結果發現團塊角孔珊瑚的攝食速率最高，每小時每公升每平方厘米珊瑚表面積的攝食率在白天和晚上分別為203±90隻及145±79隻豐年蝦的...

Ecosystems comprise large groups of highly interdependent organisms. Cnidarians, such as sea anemones and corals, are keystone species in many marine ecosystems, especially coral reefs. Each individual cnidarian also constitutes an ecosystem unto itself, a "holo- biont", consisting of the host animal and accompanying microbial symbionts. To interro- gate cnidarian holobionts, I used computational approaches to analyze the transcriptomes of three cnidarians and build mechanistic models of th...

Coral reefs are the proverbial rainforests of the ocean, but these spectacular structures are under threat from globally rising sea surface temperatures and ocean acidification. The Red Sea and the Persian/Arabian Gulf (PAG) display unusually high sea surface temperatures, and therefore, provide a model for studying environmental change. Corals are so-called holobionts consisting of the coral host, photosynthetic algae (Symbiodiniaceae), along with other microorganisms, such as bacteria, ar...

Herbivory is a key process that mediates the abundance of primary producers and community composition in both terrestrial and aquatic ecosystems. On tropical coral reefs, changes in herbivory are often related to phase shifts between coral-dominance and dominance by seaweeds, or foliose macroalgae. Resilience or capacity to resist and reverse such phase shifts is, therefore, viewed as a critical function on coral reefs. This thesis used grazer exclusion and assay experiments at six sites within ...

Cuba is an ecological rarity in Latin America and the Caribbean region. Its complex political and economic history shows limited disturbances, extinctions, pollution, and resource depletion by legal or de facto measures. Vast mangroves, wetlands, and forests play key roles in protecting biodiversity and reducing risks of hazards caused or aggravated by climate change. Cuba boasts coral reefs with some of the region's greatest fish biomass and coral cover. Although it has set aside major protecte...

Coral reefs have one of the highest levels of biodiversity of all ecosystems in the world and are important for both human livelihood and food security throughout many tropical countries. However, due to increased anthropogenic pressure on marine ecosystems, especially during the last couple of decades, coral reefs have become critically over-fished, and many reefs are now in a degraded state and are facing additional future threats due to further over-exploitation, chemical pollution, sedimenta...

Coral ecosystems are highly diverse and productive ecosystems in tropical and subtropical oceans, playing a significant role in marine ecosystems. They have many important functions: a carbon sink in the global carbon cycle via calcification, habitats for many economically important species, acting as shoreline buffers, and a potential source of natural chemical substances of medical importance (Moberg et al. 1999). Growth and erosion are the two driving forces that determine the fate of a coral...

<p> Coral reef ecosystems worldwide are facing increasing degradation due to disease, anthropogenic damage, and climate change, particularly in the Tropical Western Atlantic. Mesophotic coral ecosystems (MCEs) have been recently gaining attention through increased characterization as continuations of shallow reefs below traditional SCUBA depths (>30 m). As MCEs appear to be sheltered from many stressors affecting shallow reefs, MCEs may act as a coral refuge and provide larvae to nearby shallow ...

Buglass, Salome

The rise of ocean temperatures globally has become a grave threat to coral reefs, as it is increasing the severity and frequency of mass coral bleaching events and post-bleaching coral mortality. The continued existence of productive coral reefs will rely on corals’ ability to undergo recovery. In 2010, Tobago’s coral reefs were exposed to severe heat stress leading to mass bleaching of up to 29-60% of colonies at observed sites. This study evaluated the impact of coral bleaching and recovery of...

Growing human populations place multiple pressures on social-ecological systems, including coastal oceans. However, the effects of long-term and/or overlapping stressors remain poorly understood, particularly over large spatial scales. My dissertation evaluated how pressures from fishing and co-occurring stressors correspond to current ecological conditions in the Danajon Bank, a coral reef ecosystem in the central Philippines. I used long-term local ecological knowledge (LEK) to map fishing pra...

Both local and global threats are affecting the health of coral reefs worldwide. In addition to endangering the livelihoods and source of food for millions of people, threats to coral reefs may result in flattening reefs, which reduce habitat complexity and the ability of reefs to protect shorelines from erosion. This could be particularly detrimental to low-lying Pacific atolls like those found in the Republic of the Marshall Islands (RMI). I examined the influence of local human disturbance an...

Genetic variation was examined in bluehead wrasse, Thalassoma bifasciatum, populations along the Florida Keys. Interpretion of mean heterozygosity (H), percent polymorphic loci per population (P), genetic similarity, and F and G statistics demonstrated a clear division of wrasse populations into "northern" and "southern" groups. Correlation and cluster analyses indicated the six reefs can be grouped in a similar fashion based on genetic and environmental data. The conclusion from this analysis o...

Biology / Ph.D. / Ocean acidification is the reduction in seawater pH due to the absorption of anthropogenic carbon dioxide by the oceans. Reductions in seawater pH can inhibit the precipitation of aragonite, a calcium carbonate mineral used by marine calcifiers such as corals. Lophelia pertusa is a cold-water coral that forms large reef structures which enhance local biodiversity on the seafloor, and is found commonly from 300-600 meters on hard substrata in the Gulf of Mexico. The present stud...

This study conducted the first high-resolution investigation of the ichthyofaunal assemblages on a high-latitude coral reef in the Western Indian Ocean (WIO). Two-Mile reef, in South Africa, is a large, accessible patch-reef, and was selected as a candidate study area. Although the effect of season in structuring coral reef fish communities is most-often overlooked, the relationship between these fish communities and their habitat structure has been investigated. In South Africa, however, neithe...

In order to properly assess human impacts and appropriate restoration goals, baselines of pristine conditions on coral reefs are required. In Saudi Arabian waters of the central Red Sea, widespread and heavy fishing pressure has been ongoing for decades. To evaluate this influence, we surveyed the assemblage of offshore reef fishes in both this region as well as those of remote and largely unfished southern Sudan. At comparable latitudes, of similar oceanographic influence, and hosting the same ...

Bermudez, Edgar F.

Acoustic telemetry is an important tool for studying the movement patterns, behaviour, and site fidelity of marine organisms; however, its application is challenged in coral reef environments where complex topography and intense environmental noise interferes with acoustic signals, and there has been less study. Therefore, it is particularly critical in coral reef telemetry studies to first conduct a long-term range test, a tool that provides informa- tion on the variability and periodicity of t...

Compared to extensive study in the northern hemisphere, very little is known of southern African palaeoclimates. This study aimed to extend understanding of the nature of and controls on southern African palaeoclimates of the last 40 000 years. Through a study of the approximately 20 000 year long Makapansgat and Wonderkrater palaeoclimatic records, and an extensive literature review of southern African palaeoclimatic studies, a number of common rainfall and temperature fluctuations were detecte...

Coral reefs are among the most diverse and productive ecosystems on earth, and are critical to the survival of tropical marine ecosystems and sustenance of local human populations. However, coral reefs are quite vulnerable to disturbances, both natural and anthropogenic. This thesis looks at how coral reef communities have responded to climactic disturbances, particularly the 1997-98 El Niño Southern Oscillation (ENSO) and subsequent coral bleaching and mortality that affected much of the Indian...

Sex-change (or sequential hermaphroditism) is a phenomenon whereby an organism functions first as one sex, and then as the other in the later stage of its life. Sex change is an adaptation that has evolved to allow certain organisms to increase fitness through resource allocation of male and female functions in a single lifespan. Since the timing of sex change in an organism is critical to its reproductive output, the size or age at sex change is expected to be plastic in response to different e...

Understanding the dynamics of open marine populations is difficult. Ecological processes may vary with the spatial structure of the habitat, and this variation may subsequently affect demographic rates. In a series of observational and experimental studies in the Bahamas, I examined the roles of emigration, mortality, and predation in the local population dynamics of juvenile coral-reef fishes. First, I documented mortality and emigration rates in populations of bluehead and yellowhead wrasse. A...

Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate local populations of coral-reef fish. In the Exuma Keys, Bahamas, fairy basslets (Gramma loreto) live in aggregations on the undersides of coral-reef le...

Thesis (Ph.D.)--University of Hawaii at Manoa, 2008. / Over the past thirty years, coral reefs have experienced extensive degradation worldwide. One etiology for this global degradation is a syndrome known as coral bleaching, a process whereby corals lose their algal symbionts or the symbiont's photosynthetic pigments degrade. Coral bleaching can be induced by diverse factors including high temperature, intense light or high-energy light, cold temperature, salinity changes and bacterial infectio...

Twenty-seven species of known or suspected coral skeletal borers were identified from shallow Hawaiian reefs. In comnarison to inventories of the borer communities collected from other tropical areas Hawaiian corals had an abundance of polychaetous annelids, fewer species of sipunculans,and acrothoracican barnacles, and far fewer boring sponges. Polychaetes were responsible for the majority of the bioerosion of dead coral in Kaneohe Bay, Oahu. Comparisons of living and dead sections of coral co...

The reef corals Pocillopora damicornis and Montipora verrucosa were cultured under various controlled temperatures and light conditions at Ulupau Head Microcosm facility. The skeletal carbonate deposited under different experimental regimes was analyzed for 13C and 18O. Coral skeletal 013C values varied with light dose and correlated with changes in zooxanthellar pigment. The o13C value of skeletal aragonite seems to be controlled by oxidation of photosynthetically produced organic matter. Funct...

The coral reefs of Kane'ohe Bay, on the windward coast of O'ahu, Hawai'i, have changed markedly over the last half century. Some of the most spectacular coral reefs in Hawai'i were reported from Kane'ohe Bay in the late 1800's and early 1900's, but with the beginning of extensive military dredge and fill operations during the World War IT era, conditions in the bay began to change dramatically. After the War, rapid urbanization of the area began and conditions in the bay continued to decline unt...

TIlis study, covering a period of eight months, was undertaken to determine if measurable changes in characteristics occur in sea water passing over a shallow coral reef. The parameters studied include salinity, temperature, current velocities, dissolved oxygen, pH, dissolved organic carbon and particulate organic and suspended inorganic carbon. Staining and microscopic observations were made to supplement the other data. The results showed noticeable increases in oxygen, pH, particulate organic...

The assessment of clonal diversity in populations of the endemic Hawaiian coral Porites compressa was undertaken using four independent assays of genotypic identity: colony morphology, immunocompatibility testing by tissue grafting, electrophoresis of soluble proteins, and chromatography of ultra-violet absorbing compounds. All methods were corroborative, but electrophoresis of soluble proteins provided the single most efficacious assay of genotypic diversity, with a 7-locus (21 alleles) system ...

Focusing on coral reef policy, this thesis challenges orthodox understanding of international environmental policy, studying environmental crises as political assemblies, and policy endeavours as power-filled networks. This requires first rendering the subject accessible for critical research by constructing a 'multiperspectival' base from which to view it, thus elucidating how a Foucauldian discourse of modernisation hides the politics of orthodox understandings of international environmental p...

A monthly resolved coral δ18O record from Sabine Bank, Vanuatu (SBV; 166.04° E, 15.94°S), extending from 2006 to 1929 CE, is used to assess the influence of sea surface salinity (SSS) on the oxygen isotopic composition of coral aragonite at this location. Monthly SSS anomalies at SBV between 2006 and 1970 are strongly correlated with monthly anomalies in sea surface temperature (SST) variations in the central Pacific cold tongue, as recorded by SST anomalies in the Niño 3.4 grid box (i.e., cano...
