Coral reefs are some of the most diverse and productive ecosystems on the planet and function as important spawning, breeding and feeding areas for many organisms in the tropical seas. The persistence of these ecosystems relies on spawning events with remarkable synchronicity during limited periods each year and the ability of coral holobionts (animal host and symbiotic community) to acclimatize and/or adapt to environmental change. The goal of this dissertation was to advance our understanding about the spatial and temporal variation in coral reproductive capability and parental effects in scleractinian corals. Specifically, this work explored for the first time (1) the spawning dynamics of a major reef building coral (broadcast spawner) from the central Pacific using a systematic sampling of the gametes in the field, (2) the ultrastructure of the egg-sperm bundle and (3) how the variability in parental environmental and physiological conditions (host and Symbiodinium) relates to the phenotype of gametes in a scleractinian coral. Spawning dynamics of Montipora capitata varied among years, months and lunar days. Synchrony and proportion of spawning colonies did not reflect differences in coral colony morphology or environment between sites. Major changes in spawned material occurred in different years, suggesting that reproductive output may have been controlled by changes in the coral's phenology and/or stress associated with larger temperature fluctuations. M. capitata is a coral with extraordinary phenotypic plasticity that can release a diverse array of gametes (depending on the parental environment) within a mass spawning event. Oocytes released by different parents were seeded with different Symbiodinium assemblages and had different biochemical traits, yielding taxonomic and phenotypic variability that may have profound implications for the early development, settlement and survival of coral offspring. Further research is necessary to understand the causes of variability in spawning at different temporal scales and how spawning cues may interact and affect the reproductive physiology at the population, organism and polyp level. Understanding these relationships will help us to better predict the effects of climate change on the phenology and reproductive success of corals, which are critical for the resilience and persistence of coral reef ecosystems.

▼ With over ~2600 oil and gas platforms (platforms) remaining in the northern Gulf of Mexico (Gulf), the Gulf States have access to one of the most unique fisheries in the world. Because of high abundances of game fishes around platform legs and the popular belief that platforms enhance fish stocks, both Louisiana and Texas have created artificial reef programs based upon the decommissioning of platforms. As oil and gas fields continue to be retired, oil and gas companies may find that “reefing” or toppling a platform may be a more economically viable alternative to complete removal of material. Questions remain about how platforms should be decommissioned and whether the moved material affects fish density by changing habitat complexity. In this study, I define habitat complexity as a change in one or all of three variables: vertical relief, footprint and volume of the structure. The objective of this study was to show which of these variables has the greatest effect on changes in fish density with depth in the water column and distance from the site. Mobile hydroacoustic surveys were taken over a period of four years, yielding target strength (TS) (dB) values and mean volume backscattering strength (MVBS) values that could be converted into fish per cubic meter, or fish density. Upon reefing, fish density at the site increased. There was no significant change in density with distance from the site but depth proved to be an important factor. Overall density increased after reefing, with the most substantial increase shown in between 40-60 m depth within the water column, the layer that contained most of the platform material after reefing. The reefed site decreased in vertical relief but increased in footprint and volume. A regression tree revealed that volume was the variable responsible for the greatest variability among densities. Even though there was a much greater percent change in overall footprint compared to volume after reefing (1,024% increase in footprint versus 55% increase in volume) volumes are 3 dimensional (m3 vs. m2) and the platforms permeable, allowing fish to seek refuge within the site.

▼ Coral reefs are particularly vulnerable to climate-change impacts such as warming sea-surface temperatures, ocean acidification and increased storm activity. In response to these changes, corals may alter their geographical distributions and expand their ranges into higher latitudes. Coral reef range expansions have occurred during past periods of warming and coral populations have survived in regions protected from adverse conditions, termed ‘refugia’, until conditions improved and reefs replenished. Modern-day climate refugia have been hypothesised in higher latitudes as well as deeper, mesophotic waters (30-150 m depth). Few studies have investigated the role of higher latitude, mesophotic environments in supporting modern corals and their potential as habitat for coral refugia and expansion.
This thesis investigates past and present coral distribution around the subtropical, mesophotic Balls Pyramid shelf and draws comparisons to the adjacent Lord Howe Island shelf. Balls Pyramid is a steep, 552 m high volcanic pinnacle in the southwest Pacific Ocean. The pinnacle occurs 24 km south of Lord Howe Island, which was considered to be the southernmost limit of modern and Late Quaternary reef development in the Pacific Ocean. This thesis aims to: 1) determine the extent to which the Balls Pyramid shelf may have supported past coral reef development; 2) establish the extent to which modern coral populations colonise the shelf; 3) predict suitable areas of coral habitat; and 4) assess whether an understanding of past and present reef development can inform on the future potential of the shelves as substrates for coral refugia and expansion.

▼ The magnitude of ocean acidification (OA) and warming predicted to occur within the next century could have significant negative effects for organisms that inhabit coral
reefs. Our
understanding of how these stressors will impact coral reef organisms is complicated by the diverse behavioral and ecological interactions that exist on these
reefs. In a series of experiments, I explored interactions between coral reef organisms, evaluated how some of these interactions may be affected by OA and warming, and then studied how environment may shape an organism’s response to a changing climate. First, through a sensory manipulated tank and a twochamber choice flume, I demonstrated that anemonefish respond to both chemical and visual conspecific cues, but they require a combination of these two cues to correctly identify conspecifics. Given that previous research indicates that fish behavioral responses to chemical cues are altered under conditions of future OA, this inability to compensate for the loss of one cue through a second cue could affect their ability to acclimate as climate changes. Second, I found that the common Caribbean mounding coral Porites astreoides, is unaffected by competition with Montastraea cavernosa and Orbicella faveolata under ambient environmental conditions, but exhibits significant reductions in photosynthetic efficiency in areas of direct contact with M. cavernosa and O. faveolata under conditions of elevated CO2 and temperature that are anticipated to occur by the year 2100. These results demonstrated that climate change can interact with competition to alter the rate and severity of coral-coral interactions on
reefs of the future. Next, I compared the effects of OA and warming on the physiology of two congeneric coral species (Oculina arbuscula and Oculina diffusa) representing temperate (O. arbuscula) and tropical (O. diffusa) environments and found that, although both corals were negatively impacted by ocean acidification and warming, the temperate coral was slightly more resistant to these stressors. This suggests that temperate species may not be as disadvantaged by climate change as one might expect and may not be easily displaced by more tropical species moving poleward as global oceans warm. Finally, I evaluated the effect of elevated temperature on the well-being of the temperate coral, O. arbuscula when collected from deeper more physically stable environments versus shallower more physically variable environments. I found that corals from both deep and shallow sites were negatively impacted by elevated temperature, but that corals from deeper sites were more strongly impacted. These findings suggest that the physiologies, biotic interactions, and behaviors of reef organisms may all be affected by climate change and that outcomes of these interactions may not be simple to predict as global oceans warm and acidify and as tropical organisms shift poleward and intermix with temperate species to form novel communities.

▼ Coral cover worldwide is in decline largely due to anthropogenic influence. In some areas
reefs are transitioning into alternative states dominated by sponges, which remain largely understudied despite their abundance and functional importance. Coral
reefs in the Wakatobi National Marine Park (WNMP), Indonesia are among the most diverse in the world but remain vulnerable to a multitude of stressors, including coastal development and the resultant sedimentation. Some degraded
reefs are characterized by high levels of sedimentation and low coral cover in this area, but support large populations of the ecologically important giant barrel sponge Xestospongia spp. Giant barrel sponges in the genus Xestospongia may be among the largest benthic invertebrates providing habitat and fulfilling ecosystem services on
reefs where coral is declining. The large size of these sponges is of particular importance as body size is mechanistically linked to pumping and nutrient cycling. This thesis examines the demographic structure and connectivity of Xestospongia spp. in four core sites within the WNMP, and attempts to elucidate the mechanisms allowing them to tolerate sedimentation.
In my first data chapter I examined the influence of environmental variability on Xestospongia spp. growth and longevity over the course of two years at four sites. Specific growth rate, density, mean volume, and environmental variables were examined and compared. Four candidate growth models were fitted to the volume data each site and compared using Akaike’s Information Criterion. Best fit models were determined using a multi-model inference (MMI) approach. Models were averaged to extrapolate size-at-age, which were validated by sponge growth on an artificial structure of known age. There was no difference in model-averaged growth rates between depths or sites of varying habitat quality despite differences in density and mean volume, perhaps suggesting that Xestospongia spp. may be less reliant on their photosynthetic symbionts and feeding heterotrophically, or are able to switch between these trophic modes to maintain growth. Size-at-age estimates placed the largest measured sponges between 24 and 30 years, in contrast with published estimates of Caribbean Xestospongia muta of over 240 years for sponges of comparable size. My results highlight the accelerated growth of these massive sponges compared to estimates from the Caribbean; these differences have important implications for how these ecologically important species should be managed.
In the second data chapter I used empirical data to construct an integral projection model (IPM) to explore population dynamics at two sites. My aim was to quantify the extent that the relationship between sponge size and growth, survival, and fecundity (vital rate parameters) influences population-level outcomes (growth or decline). Indicators of asymptotic population dynamics (stable size distributions and long term growth rate) and elasticities of vital rate parameters were calculated. The importance of…

▼ Cnidarian–dinoflagellate symbioses, particularly those between anthozoans and
dinoflagellates of the genus Symbiodinium (commonly referred to as zooxanthellae)
are widespread in the marine environment. They are responsible for the formation of
coral
reefs and are thus of great ecological importance. In recent years there has been
an increase in the frequency and severity of episodes of coral bleaching resulting in
degradation and mortality of coral
reefs on a global scale. In order to gain a deeper
understanding of how corals can adapt to changing environmental conditions, the
effect that symbiont type has on the persistence and physiology of an association
needs to be ascertained. The aim of this research was to determine how different
symbiont types affect the nutritional biology and intracellular physiology of the
symbiosis when in association with the sea anemone Aiptasia pulchella. The specific
objectives of the study were to; (1) determine whether different symbiont types are
equally as adept at supporting the energetic demands of the same host; (2) determine
if internal pH (pHi) is a reflection of symbiont type and whether the optimal pH for
photosynthesis coincides with the host cell pHi; and (3) test the influence of
Symbiodinium type on host tissue glycerol and glucose pools.
In order to answer these questions, aposymbiotic (i.e. symbiont-free) sea anemones
were infected with different Symbiodinium types and the relationship between
symbiont type, photosynthetic performance and autotrophic potential was tested. A
range of ‘normal’ and novel cnidarian–dinoflagellate symbioses was also used to
measure host cell pHi and to determine the optimal pHi of isolated intact
symbiosomes (i.e. the vacuoles that house the symbionts), as well as to compare the
amounts of free glycerol and glucose (metabolites) present in the host tissues.
Different host-symbiont combinations were found to have different photosynthetic
and respiratory attributes. Earlier onset of full autotrophy (i.e. when all metabolic
carbon demands of the symbiosis were met by photosynthesis) and higher CZAR
values (i.e. the contribution of zooxanthellae to animal respiration) were
demonstrated by symbioses hosting Symbiodinium B1 both from the original
(homologous) and different (heterologous) host. The study showed that Symbiodinium
types differ in their pH optima and that the optimal pHi for
photosynthesis does not always match the actual measured pHi. Symbiont type was
also shown to have an effect on host tissue glycerol and glucose pools, with the
associations harbouring the homologous Symbiodinium B1 attaining the highest
concentrations of both metabolites.
Findings from this study suggest that corals may be able to maintain an association
with a range of Symbiodinium types, and hence potentially switch as a consequence
of bleaching. The new symbiont type may not be as nutritionally advantageous as the
original type however, which could have implications for the growth and
survivorship of the coral, unless it is able to supplement its carbon…

▼ Oyster reef restoration is an increasingly used tool to combat habitat loss and restore
ecosystem services that reefs provide. A limited supply of oyster shell for restoration practices
has prompted research focused on understanding the value of alternative substrates for reef
construction. We restored 6 acres of subtidal oyster reef complex in the Mission-Aransas
Estuary, TX, in July 2013 using replicated sections of concrete, limestone, river rock, and oyster
shell substrates. Oyster and reef-associated faunal development were assessed for 18 months
post-construction. Oyster populations varied seasonally and by substrate; the highest oyster abundance across all substrates was observed during July 2014 (X= 1288 m-2). Concrete (X =1022 m-2) and limestone (X = 939 m-2) supported the greatest number of oysters over all dates. Motile macrofauna also varied with season and substrate type; abundance and was highest during July 2014 (X = 2766 m-2) and October 2014 (X = 1748 m-2). Oyster shell (X =1533 m-2) and concrete (X = 1047 m-2) substrates supported the highest abundances of motile fauna. Faunal diversity (Hill's NI) peaked in April 2014 (X = 4.1) and did not vary by substrate material. All substrates were successful at providing habitat for oyster and faunal communities-but were
effective to varying degrees for different metrics-suggesting that substrate choice should be dependent on restoration goals. We developed a simple benefit-cost ratio to determine which substrates had the best return on investment for our restoration goals. The metric is flexible so practitioners can adapt it to suit their own project goals and substrate costs. As oyster reef
restoration activities continue at small and large scales, substrate selection criteria are critical for assisting stakeholders in ensuring restoration investments are maximizing enviromnental benefits per dollar spent.

▼ Abiotic variables are well known community regulators and can strongly influence species distributions when they are outside of a species physiological tolerance limits. However, environmental variables within tolerance limits may also alter species distributions, morphology, predator-prey interactions, and influence the structure and function of communities. The purpose of this study was to determine how abiotic variables (notably turbidity) alter diversity, species distributions and abundances, predation rates on and species morphology.
Texas Parks and Wildlife Department Fisheries Independent Survey Data from 1991-2008 were used in addition to field surveys of St. Charles Bay to determine the effects of turbidity on fish and crab diversity and abundance. Feeding assays were conducted in the field using groups of 5 mud crabs and 10 juvenile oysters to assess feeding rates in high and low turbidity. Juvenile oysters were also allowed to grow in the field to test the effects of turbidity on oyster growth. In addition, the effects of wave energy on oyster reef species composition and size were assessed using field surveys.
I found that turbidity affects top-down control and biodiversity in estuaries and has similar effects to salinity and temperature. Elevated turbidity reduced fish diversity and abundance (p < 0.01), while increasing the diversity and abundance of crabs (p < 0.01). Predation by visual fish predators was also reduced in elevated turbidity (p = 0.02), which leads to an increase in the abundance of crabs and increased predation on mud crabs in high turbidities (p = 0.03). Juvenile oysters respond to increased crab abundance by growing heavier shells, which may lower fecundity. In laboratory assays, increased turbidity decreased the predation efficiency of visual predators (fish) but not of chemosensory predators (crabs). Differences were found between wave exposed and wave protected areas. Areas with higher wave energy had fewer species (p < 0.001) and the average size of species was smaller.
This research identifies turbidity as an important variable within estuarine systems and extends the effects of wave energy from rocky intertidal systems to oyster reef communities. Both of these variables should be considered for effective management and restoration of estuarine communities.

▼ Coral reef ecosystems have been degrading globally for decades due to global climate change and anthropogenic pressure, and corals are expected to continue declining in the future. Some coral reef sponges, although also vulnerable to warmer seawater, are more tolerant than corals to the combined effects of projected ocean warming and acidification. As a result, sponges have been proposed as potential winners on future coral
reefs. Shifts towards sponge dominance on coral
reefs may result into altered reef trophodynamics. However, there is limited information on how ecological processes on coral
reefs will be affected by an increase in sponge dominance. Therefore, the potential ecological functioning of sponge-dominated
reefs is unclear. To understand how reef ecosystems could function if sponges will become dominant, it is important to clarify: how perturbations that have a negative effect on corals propagate through the reef ecosystem; how sponge assemblages can develop over time; and how increased sponge dominance will affect other coral reef organisms. Focusing on Indo-Pacific coral
reefs, this thesis investigates the temporal dynamics and the ecological processes that characterise
reefs where sponges form abundant and highly diverse assemblages. Aims of this thesis were: 1) to explore the ecosystem-level effects of climate change-induced shifts towards sponge dominance on coral reef ecosystems; 2) to quantify the temporal variability of sponge abundance and biodiversity on coral
reefs; 3) to understand how benthic sessile organisms benefit from free substrate that becomes available when corals die; 4) and to determine whether sponges can provide structural complexity similar to that of corals.
In my first data chapter, I use qualitative mathematical modelling to identify the key ecological processes that determine the functioning of a sponge-dominated reef. With a set of qualitative models, I obtain qualitative predictions of the ecosystem-level effects of increased temperature, acidity, and turbidity on a coral reef ecosystem, and of a shift towards sponge dominance. Model predictions showed that simulated environmental change caused coral decline, subsequent loss of reef structural complexity, and increased sponge and macroalgal abundance, while enhancing secondary productivity and detrital pathways. By analysing the uncertainty around model predictions, I highlight the need to elucidate some aspects of sponge ecology to better understand how sponge-dominated reef may function. These processes include temporal changes in sponge assemblages, competitive interaction between sponges and algae, and the contribution of sponges to reef structural complexity. I address these aspects in the following chapters.
In my second data chapter, I characterise the temporal variability of an abundant and diverse sponge assemblage on an Indonesian coral reef (Hoga Island, Wakatobi Marine Park, SE Sulawesi), studying temporal changes in sponge abundance and biodiversity over 13 years (2005-2017). Mean sponge abundance showed…

▼ Marine communities in the Anthropocene are changing rapidly with potentially severe consequences for ecosystem functioning. Recently, there has been increased interest in the ecological role of sponges, particularly on coral
reefs, driven by evidence that sponges may be less affected by this period of environmental change than other benthic organisms. The Sampela reef system in the Wakatobi Marine National Park, Indonesia, is an example of a reef that has shifted to sponge dominance following a decline in hard corals and an increase in sponge density. Previous research suggests that the Sampela reef system may support a greater abundance of spongivorous fishes relative to surrounding
reefs, however, uncertainties remain regarding spongivore identity and predated sponges. In addition, little is known about how shifts towards sponge dominance affect the trophic structure of
reefs. The primary aim of my thesis was to investigate sponge trophic interactions to gain insight into the way sponge-dominated
reefs of the future might function. This information is essential to predict the broader functional consequences of increasing sponge dominance on
reefs in the Anthropocene.
In my first data chapter, I measured the functional impact of spongivorous fishes by quantifying sponge biomass consumption on Wakatobi
reefs. Video analysis identified 33 species from 10 families of reef fish grazing on Xestospongia spp., although 95% of bites were taken by only 11 species. Gut content analysis indicated that Pygoplites diacanthus and Pomacanthus imperator were obligate spongivores and Pomacanthus xanthometopon, Zanclus cornutus and Siganus punctatus regularly consumed sponges. In situ feeding observations revealed that sponges from the family Petrosiidae are preferred by P. diacanthus and Z. cornutus. Spongivores were estimated to consume 46.6 ± 18.3 g sponge 1000 m- 2 of reef day-1 and P. diacanthus had the greatest predatory impact on sponges. While estimates provided here are conservative and likely underestimate the true magnitude of spongivory on Indo-Pacific coral
reefs, this chapter provides the first known estimate of reef wide sponge biomass consumption. Comparisons with published data estimating coral consumption by Chaetodontids in the Pacific suggests that biomass transferred through both pathways is similar in magnitude. Hence spongivory is an important, yet overlooked, trophic pathway on Indo-Pacific
reefs.
In my second data chapter, I developed genetic methods to identify sponges from the stomach contents of spongivorous angelfishes sampled in my first chapter. A range of primers and associated predator-blocking primers targeting the 18S rDNA gene were designed and tested on extracts of sponge and spongivore DNA. Sequences were successfully amplified from 14 sponges spanning 6 orders of Porifera, with the majority of samples identified belonging to the order Haplosclerida. This study is the first to successfully sequence sponges from the gut contents of spongivorous fishes. Sequence data indicated that Pygoplites…

▼ Ph.D. University of Hawaii at Manoa 2013.
Coral reefs are some of the most diverse and productive marine ecosystems on earth. They are also among the most threatened by human disturbance. On a local scale, many of these systems are subject to over-fishing and land-based pollution, and on a global scale, these systems are impacted by climate change and ocean acidification: human activities clearly influence the structure of coral reef communities. However, before considering anthropogenic influence, it is necessary to consider the influence of local and regional environmental forcings on these ecosystems.
In this research, I investigate natural environmental and anthropogenic drivers of benthic community organization in 41 coral reef ecosystems across the Pacific (14.2°S – 28.4°N, 144.8°E – 155.4°W). These systems have been the focus of a long-term, multi-disciplinary NOAA-led monitoring effort. I present a new methodological approach to spatially constrain environmental forcings at the scale of individual islands and atolls. The results indicate considerable spatial heterogeneity in environmental forcings, namely sea surface temperature, waves, chlorophyll-a concentration (a proxy for phytoplankton biomass) and irradiance. Further examination of long-term (10-year) chlorophyll-a concentrations revealed sustained increased phytoplankton biomass just offshore of reefs compared to surrounding oceanic waters around a majority (91%) of islands and atolls, providing widespread evidence of the occurrence and scale of the "island mass effect". Additionally, significant differences in horizontal gradients in chlorophyll-a between island and atoll systems were observed. Variations in reef area, bathymetric slope, geomorphic type (e.g. atoll versus island), and human population were identified as important drivers of increased phytoplankton biomass, together explaining 77% of the variability observed. In order to investigate biological-physical relationships at a smaller spatial scale, I focused on one oceanic atoll with a history of minimal human influence, Palmyra Atoll (5.8°N, 162.1°W). At intra-island scales, wave forcing and reef geomorphology were important drivers of benthic community organization. Model performance improved when hard coral cover was modeled in distinct morphological groups (encrusting, plating, branching), highlighting the response of coral reef communities to extrinsic physical forcings. Superimposed on natural variations in coral reef benthic community organization are the effects of anthropogenic disturbance.

▼ A detailed investigation of the internal and external architecture of the shelf-edge reefs (SERs) of the Great Barrier Reef (GBR), Australia is presented here, constituting the most comprehensive seismic stratigraphy study of these drowned reefs. In two sites of the central GBR, seismic reflectors and facies were identified, ground-truthed against core and downhole data from the Integrated Ocean Drilling Program, Expedition 325. Marked depositional differences between the two sites were found and linked to local and regional physiographic and environmental contrasts. A sequential stratigraphy framework was established for these sites, which exhibit a complete depositional sequence dominated by transgressive reefs, bounded by two flooding surfaces. The postglacial flooding of the GBR shelf was also simulated. The measured parameters suggest a strong influence of the local antecedent substrate and of the interplay of regional physiographic variations and sea level change in the development of the SERs. Supported in these new interpretations, local and regional SERs CaCO3 accumulation were estimated. It was found that the Pleistocene SERs of the GBR are equivalent to ca. 20 % of the GBR's Holocene reef mass. Both the magnitude and the timing of the shelf-edge reef accumulation suggest that the drowned reefs in the GBR (and globally) had the potential to influence postglacial climate change. In addition, forward stratigraphic simulations were run on models based on this dataset, which suggest that the ensemble of conditions for reef growth deteriorated as the transgression advanced, resulting in shelf-edge reef demise. The role of the basement substrate was significant, but limited. All together, the multidisciplinary reconstructions in this study represent a useful framework to constrain the development of these under-studied formations, which according to the findings had a significant role in shaping the Quaternary GBR and, possibly, in postglacial climate change.

▼ Coral reefs are among the world’s most biodiverse and valuable ecosystems, but they are in global decline. One major concern for the future of reefs is mass coral bleaching, a phenomenon where corals turn white after expelling their endosymbiotic algae (Symbiodinium) during periods of elevated sea surface temperatures. Unfortunately, the frequency and severity of mass coral bleaching is increasing as climate change results in global sea surface temperature rise. Extensive research has examined how Symbiodinium variation influences bleaching susceptibility, yet Symbiodinium is only one part of a complex coral holobiont that also include bacteria and archaea. This dissertation investigates variation in coral microbiomes in the world’s largest and most diverse coral reef ecosystem, the Indonesian Archipelago. Using a common garden approach, Chapter 1 investigates how the microbiome of Porites lobata varies with water temperature among two nearby reef ecosystems that experience different levels of coral bleaching—Amed and Pemuteran, Bali. Results reveal significant local variation in microbiomes, but no consistent changes in microbiomes with temperature. Chapter 2 examines how the coral microbiomes of three species of coral with different bleaching susceptibility (Acropora millepora, Pocillopora verrucosa, and Porites lobata) respond to elevated water temperatures in a single location, Manokwari, West Papua. Results show significant differences in microbiomes in all three species, indicating species-specific relationships between coral host and microbial symbionts. However, while microbiomes changed with elevated temperature, there were no consistent patterns by species or by propensity to bleach. Lastly, chapter 3 examines natural variation in microbiomes of these same three species of coral across 5000 km of the Indonesian Archipelago, including reefs with historically low, moderate, and high bleaching susceptibility. Results varied by species: microbiomes of Acropora millepora showed no significant geographic variation; microbiomes of Pocillopora verrucosa were significantly different among most locations, but not among regions; and microbiomes of Porites lobata showed significant variation based on regional variation in bleaching susceptibility, but not among individual localities. Combined, these studies show that coral microbiomes are complex, varying by species, reef, and geographic region, providing novel insights into the nature and specific relationship of microbiomes to coral host and their environment.

▼ Mechanisms of change in coral colonies are necessary components to accurately predict trajectories of coral reef health. Yet, little in-field data has been quantified regarding the demographic rates of change in colonies and the factors that influence them. In this study, we use a large-area imaging approach to estimate baseline demographic rates of the coral genus Pocillopora and test for the influence of colony-specific predictors on growth, shrinkage (i.e. colony survivorship with loss of live tissue), and mortality (i.e. whole colony loss). We found that a colony’s fate was linked to its initial size, with larger colonies experiencing far lower mortality rates but higher shrinkage rates than smaller colonies. In addition, historical effects also significantly affected colony fate, as colonies with recent history of shrinkage experienced further shrinkage and mortality the following year. Finally, we found that significant variability in growth and mortality rates were linked to in inter-island site differences, which we suspect is driven by differences in heterotrophic feeding rates.

▼ This dissertation was carried out with an aim of advancing the concept of establishing small, no take MPAs as a solution to sustainable reef use and conservation in the tropical atoll of Agatti, India. This was done by first carrying out a review of literature based on coral reef atoll management using co-managed MPAs. Second, a case study approach was used to analyse documents pertinent to Agatti’s socio-ecological system (SES). After careful analysis of the Agatti atoll and its parent archipelago, it was realised that the said atoll has certain inherent obstacles which hinder its sustainable development. However, this study also found out that the island community has latent potential for co-management. Therefore it was recommended that this aspect needs to be further explored and exploited through intensive consultations by the government. An indicative SES Framework was developed for Agatti with an element of a co-managed MPA fortifying the reef and its people. Implementation of this framework has the potential to lead Agatti towards sustainable development.

▼ For hundreds of years, coastal and marine ecosystems have experienced increasing threats due to the cumulative effects of increasing population growth and dependence on these ecosystems. Thus, there has been increased enthusiasm to mitigate the negative effects of human actions through the use of cleaner sources of energy, like marine renewable energy (MRE). The U.S. West Coast shows potential for tidal, wave, and offshore wind energy. Concern about MRE deployments has motivated research on the environmental effects of these new man-made hard structures in the ocean. Although this kind of development is relatively new in the U.S, placing man-made hard structure in coastal and marine ecosystems around the world has shown to create new habitat for algae, invertebrates, and fish and create foraging opportunities for birds and mammals, eventually becoming an artificial reef. The overall goal of my research was to use existing artificial structures to investigate a few specific effects of MRE development in Oregon waters. My research had two components: to assess the extent to which soft-sediment habitats are influenced by the presence of artificial structures deployed in Yaquina Bay, OR, and to characterize the biofouling communities present on bottom and surface artificial structures deployed offshore. Previous research indicates artificial structures modify sediment composition by increasing the erosion around a structure and that there is a close link between infaunal communities and sediment composition. Grain size analyses confirmed artificial structures change the physical environment around them, although these
differences were not sufficient to cause a visible change in infaunal communities. Sediment characteristics also did not explain the greater infaunal abundances, mainly of Capitellidae polychaetes, closer to the structures than further away. Results indicated there were significant differences in sediment characteristics between locations in Yaquina Bay, most likely because of the greater amount of fine sediment at the sites located further upstream than those located closer to the mouth of the estuary. These differences in sediment characteristics appeared to be large enough to see a grouping of infaunal communities with location in Yaquina Bay. This study provided additional evidence that artificial structures alter their physical environment, but these structures and physical effects did not change the composition of the infaunal communities after a period of eight years. Assessing the biofouling cover on the offshore bottom and surface artificial structures showed that after a period of two years, the biofouling communities on the offshore bottom structures mostly consisted of balanoid barnacles, which resulted in little biomass. The bottom structures appeared to have been tipped over during their time in the water, potentially preventing the biofouling communities from developing more. In contrast, the surface artificial structures had greater overall cover, although cover mostly consisted of algae…

▼ Mass bleaching events induced by climate change are threatening coral reef ecosystems worldwide. Elevated seawater temperatures cause breakdown of the coral’s endosymbiotic relationship with dinoflagellate algae from the genus Symbiodinium. Corals rely on these symbionts for the majority of their metabolic carbon (provided by photosynthetic products) and for efficient nitrogen cycling in the reef ecosystem. Researchers have predicted that corals may potentially adapt to higher ocean temperatures according to the Adaptive Bleaching Hypothesis (ABH), which states that bleaching can facilitate a change in symbiont communities, allowing more thermally tolerant symbionts to become dominant. Hosting thermally tolerant symbionts thus grants the coral a higher resistance to bleaching. However, confidence in this adaptation method has wavered due to the nutritional impairments of hosts harbouring thermally tolerant symbionts under normal environmental conditions. It is also unknown if coral species that do not currently associate with thermally tolerant symbionts would be able to successfully switch their symbiont communities. Here, I explore the mechanisms driving nutritional exchange in the symbiosis and determine the effect of establishing a non-native (heterologous) association with a thermally tolerant symbiont. A combined approach of bioinformatic analysis with proteomic and isotopic labelling experiments is used to uncover a link between host-symbiont cellular integration, the potential for nutrient exchange, and the success of establishing a symbiosis.
In Chapter 2, I characterized membrane protein sequences discovered in publicly available cnidarian and Symbiodinium transcriptomes and genomes to identify potential transporters of sugars into cnidarian cells and nitrogen products into Symbiodinium cells. I examined the facilitated glucose transporters (GLUT), sodium/glucose cotransporters (SGLT), and aquaporin (AQP) channels in the cnidarian host as mechanisms for sugar uptake, and the ammonium and high-affinity nitrate transporters (AMT and NRT2, respectively) in the algal symbionts as mechanisms for nitrogen uptake. Homologous protein sequences were used for phylogenetic analysis and tertiary structure deductions. In cnidarians, I identified putative glucose transporters of the GLUT family and glycerol transporting AQP proteins, as well as sodium monocarboxylate transporters and sodium myo-inositol cotransporters homologous to SGLT proteins. I predict that cnidarians use GLUT proteins as the primary mechanism for glucose uptake, while glycerol moves into cells by passive diffusion. I also identified putative AMT proteins in several Symbiodinium clades and putative NRT2 proteins only in a single clade. I further observed a high expression of putative AMT proteins in Symbiodinium, which may have resulted from adaptations to conditions experienced inside the host cell. This study is the first to identify transporter sequences from a diversity of cnidarian species and Symbiodinium clades.

Environmental and biotic controls affecting recruitment and proliferation of algal turf communities in coral reef systems.

▼ Worldwide, coral reef communities are collapsing and shifting from coral to algal dominance. While human activities changing top-down (overfishing of grazers) and bottom-up (increases in nutrients and sediments) forces can initiate shifts, complex, non-linear interactions among stressors limit predictability (Hughes et al., 2007;Bellwood et al., 2004). Further, while top-down control is known to limit algal dominance (Knowlton & Jackson 2008; Jackson et al., 2001), less is known about bottom-up controls that may facilitate algae. One functional group of algae is turf algae, which are multi-species and often filamentous, ranging from 0.01-10cm in height (Fong & Paul 2011). Short, closely-cropped turf algae provide ecosystem functions such as primary productivity, trophic support, and nutrient cycling (Fong & Paul 2011). Under environmental stress, however, turf algae can shift to long sediment-laden turf, which may be an alternative stable state that inhibits coral recovery (Adjeroud et al., 2009). My first objective was to compare variation in the assembly of turf algae under a suite of top-down and bottom-up contexts at six sites on fringing reefs in Mo’orea French Polynesia. At each site, 10 settlement tiles were deployed and monitored for two-months and then after twelve months. During the first two months I also measured herbivore abundance, grazing pressure, sediment composition, nutrient availability, benthic community structure, and sediment deposition rates at each site. After two months turf did not vary among plots, despite significantly different herbivore abundances and nutrient availability. This implies that early successional forms are easily controlled, even by low numbers of herbivores, due to their high palatability. In contrast, after one year, tiles in highly grazed sites with low sedimentation rates were dominated by crustose coralline algae, and sites with low herbivores and high sedimentation rates dominated by long turf and macroalgae. As crustose coralline algae can facilitate coral recruitment, these results imply that herbivory can mediate the successional trajectory of algal communities toward recovery by coral or stability of the shifted algal state. A robust herbivorous fish community is the paradigm of a healthy coral reef, however, altered sediment regimes can negatively influence their grazing patterns (Tebbett et al., 2018;Bellwood & Fulton 2008), leading to algal proliferation. While increases in sediment can lead to algal proliferation through reduced grazing and release from nutrient limitation, too much sediment can lead to negative turf responses (Tebbett et al., 2018) due to the buildup of anoxic-inducing bacteria (Clausing et al., 2014). Turf are particularly prone to the influence, both positive and negative, of sediment fluxes due to their filamentous nature that trap deposited sediment (Rogers 1990). The second objective of my dissertation was to establish the non-linear relationship between sediment and turf at two sites that varied in environmental context.…

▼ The Rabigh coast (Saudi Arabia) in the study area stretches for about 12 km between Al Kharrar Lagoon in the north and Sharm Rabigh in the south. Seven prominent Pleistocene coral reef sites were investigated with terrace heights ranging from 1 to 5 m above present sea level. In addition to field descriptions, 86 samples were collected from these seven sites to provide the data for this research. Of these seven sites, 4 of the sites were front reef, and 3 were back reef. In each of the front reef sites, there was a beach rock, upper and lower reef. The elevation of the upper and lower reef in the front reef sites ranges from 0.5 m to 3.20 m above present sea level. The two layers of beach rock and a back reef were identified in the study area. In the upper and lower reefs, corals were observed in almost all of the samples, with higher proportions for the upper than lower reef. Silicate minerals were rare in both lower and upper reef. The back-reef features much less coral compared to the lower and upper reef and algae was the dominant element in the beach rock. The upper reef can be part of the reef crest or the algal ridge in the reef system, such that erosion can occur at the front reef. The lower reef indicates an outer reef flat where this zone is a combination of the fore reef and lagoon environment with wave-breaking algal structures. The coral framework in the upper reef indicates a low energy environment during the formation of this reef. Within the back-reef calcareous mud was dominant, which indicates a low energy environment behind the reef crest, or a lagoon environment. Such an interpretation for the upper and lower reefs connects with transgression phases of the sea and represents slightly higher sea levels. The XRD results for the upper and lower reefs, and beach rock revealed variable percentages of aragonite followed by high-Mg calcite, and calcite, with a small increase in calcite and high-Mg calcite comparative to the lower reef. Calcite was the dominant mineral in the back reef area, with variable percentages of high-Mg calcite. The dominant diagenetic process in the Rabigh reefs was cementation. Fibrous calcite occurred in many upper and lower reef samples, and blocky calcite spar was the most common cement type in the back-reef area. Lower and upper reef were exposed to freshwater dissolution and cementation. There was also more cementation and diagenesis in the lower reef compared to the upper reef, and an equal distribution of calcite cement around most of the grains, with an average porosity of 14.8%, consistent with fresh water phreatic environment. The beach rock was suggestive of marine phreatic diagenesis. Amino Acid Racemisation (AAR) and 14C dating of bivalve shells from upper and lower reef were unsuccessful for deducing the age of these reefs. U/Th dating produced the most reliable results for the age of the reefs. The reefs were probably formed during the major highstand of isotope stage 5 where the age of the upper reef is more likely to be 122.8 ka (MIS 5e) whereas…

▼ Coral reef degradation has been observed worldwide over the past few decades resulting in significant decreases in coral cover and abundance. However, there has not been a clear framework established to address the crucial need for more sophisticated understanding of the fundamental ecology of corals and their response to environmental stressors. Development of a quantitative approach to coral population ecology that utilizes formal, well established principles of fishery systems science offers a new framework to address these issues. The goal of this dissertation is to establish a quantitative foundation for assessment of coral
reefs by developing some essential ecological and population-dynamic components of a size-structured demographic model for coral populations of the Florida Keys coral reef ecosystem. The objective provides the potential to build a quantitative systems science framework for coral populations. A two-stage stratified random sampling design was implemented during two separate survey periods to assess coral populations. Results include precise estimates of adult (> 4 cm) population abundance for several coral species by spatially partitioning abundance and variance into species-relevant reef habitat types. Adult size structure and juvenile abundance were used to evaluate individual coral populations and infer spatial variation in recruitment, growth and survival across habitat types. Partial mortality was characterized in terms of surface area, prevalence, and size-relationships. The development of some ecological and population-dynamic components of a size-structured demographic model for coral populations demonstrates the statistical framework and metrics required for monitoring and assessment of coral reef ecosystems to meet the pressing needs of conservation of coral reef ecosystems specifically in Florida, and throughout the Caribbean and Pacific in general.

▼ The island Territory of Guam is about to experience a large U.S. military buildup. This buildup will set Guam as host of the largest U.S. military presence in all of Asia, with correspondingly advanced Naval base facilities. Part of Naval Base Guam capacity improvements will include significant dredging in Apra Harbor, home to the island’s only deep-water lagoon. This lagoonal area is not only host to a United Stated Naval base, but is also host to Guam’s commercial port and a highly attractive area for many recreational tourism activities. As a preparatory step before dredging activities occur, the island’s dive businesses have been surveyed in order to establish baseline socioeconomic information on the use of Apra Harbor’s coral
reefs and to assess the potential impacts a Navy dredge project might have on dive businesses utilizing Apra Harbor coral
reefs. This study concludes that Apra Harbor’s coral
reefs are an incredibly important asset to Guam’s dive businesses, as the
reefs are used for approximately 60% of dives annually conducted by surveyed businesses. One hundred percent of surveyed businesses utilize Apra Harbor coral
reefs for dive and/ or snorkel trips, which cater mostly to the industry’s largest clientele: novice divers/ snorkelers. Depending on the amount of dredge-based sediment settling on Apra Harbor’s reef areas, the Navy dredge project has the potential to impact $1,253,340 in annual total revenues made by surveyed dive businesses. Given that Apra Harbor’s coral
reefs are highly utilized and depended upon by surveyed businesses, it is presumed that dredge-based sediment settling on the Harbor’s coral
reefs will directly impact dive business activity occurring within Apra Harbor both during and after dredging occurs.

▼ Over the last two decades there has been a proliferation of reports documenting the decline of coral reef systems across the globe (Gardner et al. 2003, Bellwood et al. 2004, Cote et al. 2005, Bruno and Selig 2007). In response, multiple studies have attempted to establish conservation baselines for benthic and fish communities using observations from remote, uninhabited coral
reefs (Sandin et al. 2008, Edwards et al. 2011, Williams et al. 2011, Smith et al. 2016). These efforts have highlighted drastic differences in the composition and abundance of benthic and fish communities between remote and populated coral
reefs. However, previous studies have focused on island- and archipelago-wide comparisons of reef communities that mask finer-scale spatial variability of coral reef communities within remote, unpopulated reef systems. The focus of my thesis was to describe the spatial variability of benthic and herbivorous fish communities across populated and unpopulated islands in the Hawaiian Archipelago and to examine how such variability affects views about coral reef conservation. I chose to focus on benthic and herbivorous fish communities because: (1) the decline of coral
reefs is often associated with persistent shifts in benthic composition from abundant reef building organisms (coral and crustose coralline algae) to abundant fleshy algae (Done 1992, Hughes 1994) and (2) the prevailing view is that herbivorous fishes are the main driver of benthic community composition and thus overfishing of herbivorous fishes contributes to benthic community shifts (Hughes 1994, Bellwood et al. 2004, Mumby et al. 2006, Adam et al. 2015). Furthermore, this topic is highly relevant in Hawaii where herbivore fishing bans are being considered and implemented to conserve and promote healthy benthic habitats. The first chapter of my thesis addressed the view that herbivorous fish are main drivers of benthic community composition in the remote Northwestern Hawaiian Islands (NWHI). I described three benthic community types (reef builder, mixed-turf, and Microdictyon) whose occurrences varied across forereefs in the NWHI. Using these community groups, I found herbivorous fish biomass to be associated with benthic composition which is consistent with prevailing views about the importance of these consumers to benthic community structure. However, herbivorous fish-benthic community relationships varied across islands and patterns suggested that environmental factors may have stronger influences on benthic community composition across some parts of the NWHI. The second chapter of my thesis examined environmental influences on four measures of herbivorous fish community biomass (total, scraper, grazer, and browser) across the Hawaiian Archipelago and their effects on estimates of unfished biomass (Bunfished) and depletion in the Main Hawaiian Islands (MHI). I found environmental factors were strongly associated with herbivorous fish biomass in Hawaii and accounting for environmental differences across islands in the archipelago resulted in…

▼ Coral reefs are one of the most diverse ecosystems on the planet, harbouring approximately twenty-five percent of the diverse eukaryotic life in the oceans, while also being important economically for millions of people worldwide. Despite their importance, coral reefs are menaced of a very steep decline due to pollution and anthropogenic climate change. In this thesis, we investigate the microbes that live close-by and inside coral reefs. It is believed that microbiomes, both environmental and coral-associated, play an important role in coral health, both by contributing to nutrient cycling, such as carbon and nitrogen fixation as well as photosynthesis, and by protecting the corals against environmental stressors such as pathogens. These microbiomes can be studied using targeted approaches, such as metabarcoding, or more general and powerful approaches, called metagenomics. Metagenomics is a relatively new field of study and the first part of this thesis focuses on method development for metagenomics. In paper I, we present InSilicoSeq, a software package to simulate metagenomic Illumina reads. InSilicoSeq is useful for testing new bioinformatics methods as well as benchmarking existing ones. In paper II and III, we study the composition of the coral microbiome from previously published studies, and the composition and function of the microbiome of the water and upper sediment layer from reefs of the Kenyan coast of the west Indian ocean. We define a putative coral core microbiome at the genus level and take a look at the metabolic pathways that may be active in the surrounding environment of the corals. While the coral core microbiome was largely dominated by one genus, Endozoicomonas, the surrounding environment showed great diversity both in taxonomy and in metabolism. We found evidence of antibiotics resistance in the water, which we hypothesise mainly comes from agriculture. We also publish a catalogue of putative expressed pathways and discovered 174 new bacteria in the water and sediment samples.

▼ Tropical marine macroalgae perform an essential role in coral reef function and health, however, their persistence in a rapidly changing ocean remains uncertain. The rise in sea surface temperatures and decrease in pH (ocean acidification = OA) are predicted to have damaging effects on marine calcifiers. Calcifying macroalgae have varied, often negative, responses to these conditions, however our lack of understanding about the mechanisms involved with calcification prevent us from interpreting these results fully. Thus, I conducted a series of experiments on five calcifying species, utilizing microsensors, radioisotopes, and mesocosms, in an attempt to define biotic and abiotic mechanisms involved in calcification and dissolution under OA. Microsensor work demonstrated that all species elevate the thalli surface pH 2-3X higher under OA, which promoted calcification. The use of a photosynthetic inhibitor revealed species-specific light-triggered thalli pH control that stimulated calcification, indicating strong biotic control over calcification. When exposed to OA conditions, stronger organismal control over calcification was shown to maintain calcification in the light. A major gap in our understanding of calcification under OA is whether it affects organismal capacity to form new calcium carbonate, or if dissolution occurs, reducing calcification rates. Using radioisotopes, I found that the ability to form new calcium carbonate under OA in the light was not affected in any species. This suggested that species with reduced net calcification were actually experiencing dissolution. This study also highlighted that all species were experiencing dissolution in the dark under OA. Finally, in a short-term growth experiment, I examined the combined effects of OA and increased temperature and found complex responses in species that are negatively affected by OA. This included a crustose coralline that appears to have an additive negative effect where temperature enhances the effect of OA but also a species that exhibited a negative effect which was evidently offset with increased temperature. Here, I define distinct abiotic (light, temperature, dissolution) and biotic (proton pump & photosynthesis), that are essential for understanding macroalgae persistence on future coral reefs.

▼ Prokaryotic and eukaryotic microbes regulate key processes in reef ecosystems but very little is known about the biodiversity of microorganisms living inside coral skeletons (i.e. endolithic). Endolithic microalgae, for example, are among the main contributors of reef bioerosion and can facilitate coral survival during bleaching events, but their phylogenetic diversity, distribution and evolutionary origins are largely unknown. We developed a high-throughput sequencing procedure to assess the biodiversity of prokaryotic and eukaryotic microbes in coral skeletons. A surprisingly high biodiversity of green algae was found, including entirely new lineages that are distantly related to known genera. This technique was then applied to study the relative effects of niche specialisation and neutral processes on the spatial distribution of endolithic communities. The results indicated that stochastic processes and dispersal limitation create a high rate of bacterial species turnover within colonies, while niche specialisation explains most of the distribution of endolithic microbes at larger spatial scales. Finally, we studied whether signatures of an endolithic lifestyle could be observed in the chloroplast genome of a common endolithic alga. The results suggested that chloroplast genome streamlining and slow rates of molecular evolution are associated with the low light inherent of endolithic lifestyles.
