Species boundaries, populations and colour morphs in the coral reef three-spot damselfish (Dascyllus trimaculatus) species complex.
Coloration patterns of tropical reef fishes is commonly used for taxonomic purposes, yet few studies have focused on the relationship between species boundaries and coloration types. The three-spot damselfish (Dascyllus trimaculatus) species complex comprises four species that vary both in geographical ranges and colour patterns making them an ideal model to study these relationships. We analys...
متن کاملAllopatric divergence and speciation in coral reef fish: the three-spot dascyllus, Dascyllus trimaculatus, species complex.
Long pelagic larval phases and the absence of physical barriers impede rapid speciation and contrast the high diversity observed in marine ecosystems such as coral reefs. In this study, we used the three-spot dascyllus (Dascyllus trimaculatus) species complex to evaluate speciation modes at the spatial scale of the Indo-Pacific. The complex includes four recognized species and four main color m...
متن کاملPopulation Regulation of Coral Reef Fishes
Populations of reef fish are widely believed to be limited by availability of larval recruits, not by density dependent processes operating during and after settlement of young stages in the reef environment. Our research explores and challenges this thinking. We are utilizing field observations and experiments to determine what factors affect spatial distribution, abundance, and population dyn...
متن کاملIsolation and characterization of 13 polymorphic nuclear microsatellite primers for the widespread Indo-Pacific three-spot damselfish, Dascyllus trimaculatus, and closely related D. auripinnis.
A set of 13 simple sequence repeat markers was developed from D. trimaculatus genomic DNA, tested for D. auripinnis and characterized using 40 individuals per species. All the loci were polymorphic with a number of alleles ranging from three to 30. Observed heterozygosities varied from 0.23 to 0.89 for D. trimaculatus and from 0.11 to 0.85 for D. auripinnis. Early results show that these will b...
متن کاملConsistent behavioural traits and behavioural syndromes in pairs of the false clown anemonefish Amphiprion ocellaris.
Using the social clown anemonefish Amphiprion ocellaris, whether individuals exhibited consistency in activity levels, boldness and sociability in a paired context, and whether these three behavioural traits were positively correlated within a single behavioural syndrome, was investigated. The results highlight that consistent individual differences in behaviour are expressed in a social fish a...
