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 …

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 …

Cryptobenthic Coral Reef Fishes: Resolving Critical Gaps in Species Delimitation, Sampling Techniques, and Phylogenetic relationships
Cryptobenthic reef fishes (CRF) are the smallest vertebrates on coral reefs but represent about 40% of the fish species and about 50% of fish abundance in coral reef ecosystems. Their diversity can be explained by their extremely limited dispersal abilities and short generation times (promoting …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
… habitats, including mangroves, seagrass beds and coral reefs, is coming under increasing pressure from human activities. Many coral reef fish species are thought to use mangroves and seagrass beds as juvenile nurseries before migrating to coral reefs as adults. Identifying essential habitats and …

An evaluation of geographic variation in the life history and behaviour of anemonefishes: A common-garden approach
… adjust to different environments. In coral reef fishes, the extent and underlying causes of such patterns across large geographic scales are poorly understood. Intraspecific phenotypic variation may be evident on a broad geographic scale, for example when comparing populations that are …

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 …

Influence of resource availability on lifehistory traits in coral-feeding butterflyfishes (Pisces: Chaetodontidae)
… the highly stochastic nature of larval supply, coral reef fishes often settle in sub-optimal habitats with limited access to prey or other resources. Variation in the availability and quality of resources among different reef habitats is likely to have significant effects on the physiological …

The ecological significance of body size in tropical wrasses(Pisces : Labridae)
… in terrestrial taxa were repeated in a group of coral reef fishes, and assess reasons for differences when predicted relationships were not detected. This study employed a multispecific comparative approach to examine life history and ecological correlates of body size in coral reef fishes of the …

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 …

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 …

Feeding ecomorphology in angelfishes, f. Pomacanthidae: the implications of functional innovations on prey-dislodgement in biting reef fishes
On coral reefs, biting teleosts form a major component of reef fish assemblages. Nevertheless, they have been largely overlooked in functional research, while their ramsuction feeding counterparts have received considerable attention over the past few decades. This thesis therefore examines the …

Geographic variation in size at age of the coral reef fish, Thalassoma lunare (family: Labridae) : a contribution to life history theory.
… theoretical predictions were yet to be tested in coral reef fish. Therefore, the objective of this project was to examine age-based parameters in discrete populations of Thalassoma lunare, a widespread and opportunistic wrasse, to evaluate whether reef fish fit predictions of traditional life …
