Coral Reef Flood Protection and Coral Growth Typology
… chosen to be studied in this thesis is the coral and more specifically, how the form and material of coral reefs are able to mitigate the damages of incoming waves as a result of storm surges. The form and materiality of the coral reefs are translated into a modular coastal protection …

Examining coral reef ecosystem dynamics using microorganisms and metabolites
… of biodiverse and economically important coral reef ecosystems and are also tightly connected. Metabolites are small organic compounds produced by reef organisms and are the chemical currencies exchanged by unicellular microorganisms (bacteria and archaea) within the seawater. Although …

Ecological evaluation of coral reef resources at Kahaluʻu Bay, Hawaiʻi
… objectives of this research were to: assess coral reef resources (coral and fish communities) present at Kahalu´u Bay, Hawai´i; and integrate scientific ecological observations with Traditional Environmental Knowledge (TEK) and cultural practices. This localized assessment is the first to …

Behavioral ecology of coral reef fishes at spawning aggregation sites
Coral reef fishes aggregate to spawn on certain locations of reefs. This thesis is an extensive investigation of the behavioral and ecological relations between spawning reef fishes, predators and their environment at a spawning aggregation site. Many hypotheses have been proposed regarding the …

Coral reef soundscapes : spatiotemporal variability and links to species assemblages
Coral reefs are biodiverse ecosystems that are at risk of degradation as a result of environmental changes. Reefs are constantly in a state of flux: the resident species assemblages vary considerably in space and time. However, the drivers of this variability are poorly understood. Tracking these …

A scientific framework for evaluating coral reef resilience to climate change
… oceans will impact the structure and function of coral reef ecosystems. Consequently, conservation efforts are increasingly focused on identifying and protecting reef communities that demonstrate resilience to these changes. In this thesis, I develop a scientific framework for identifying climate …

The structure and dynamics of spawning aggregations of coral reef fish
… and dynamics of spawning aggregations of coral reef fish The specific aims are to identify and characterise: (1) the species of coral reef fishes that formed spawning aggregations, (2) the locations where spawning aggregations were formed, (3) the periodicity with which these aggregations …

Parametric, Non-Parametric And Statistical Modeling Of Stony Coral Reef Data
Like coral reefs worldwide, the Florida Reef Tract has dramatically declined within the past two decades. Monitoring of 40 sites throughout the Florida Keys National Marine Sanctuary has undertaken a multiple-parameter approach to assess spatial and temporal changes in the status of the ecosystem. …

Coral Reef Valuation and Perceptions of the Tourism Industry in Akumal, Mexico
… residents have toward the Mesoamerican Barrier Reef System (MBRS) in Akumal, Quintana Roo, Mexico, a coastal community located on the Yucatán peninsula. Data were collected during May 2005 from two distinct groups who utilize the unique coral reef resource for different reasons. The study sample …

Coral reef health indicators: integrating ecological and perceptual assessments of anchor damage
… is explored here by assessing the condition of coral reefs associated with different intensities of anchoring, using both an ecological and a social perspective. Specifically, the research aims to: 1) identify environmental indicators to evaluate management strategies; 2) identify perceptual …

Effects of fishing on a coral reef fish assemblage in Northeastern Brazil
Reef fisheries are important activities that support the livelihoods of millions of people. Reef fisheries exploit different habitats and typically target a diversity of species caught with a matching diversity of fishing gears. However, previous studies of reef fisheries have generally lacked …

The population genetic structure of coral reef fishes on the Great Barrier Reef
… investigated the population genetic structure of coral reef fishes on the Great Barrier Reef (GBR), Australia to better understand how these various processes may interact in a natural system. I firstly examined the spatial genetic structure of a low dispersal species to determine if its genetic …

Characterizing the ecology of coral reef microorganisms across different scales within the Caribbean
Microorganisms sustain the high productivity of coral reefs and support one of the most diverse, valuable, and threatened ecosystems on Earth. Despite the importance of reef microorganisms, there is a lack of understanding about their ecology, especially on Caribbean reefs. Furthermore, the …

Energy harvesting using ocean data acquisition system (ODAS) buoy for coral reef monitoring
The threat to coral reefs in the ocean and coastal areas is growing, the main thing that threatens coral reefs is weather changes and human activities. If this is not in concern it will damage the coral reef which is the habitat of most marine life. There are several methods to monitor the coral …
