Species boundaries and evolutionary lineages in the blue green damselfishes Chromis viridis and Chromis atripectoralis (Pomacentridae)
نویسندگان
چکیده
The blue green damselfishes were described as a complex of two species (Chromis viridis and Chromis atripectoralis), mainly based on the colouration of the pectoral fin base. In this study, the authors analysed the mitochondrial control region of 88 blue green damselfishes from Indonesia, the Philippines, Red Sea and the Great Barrier Reef. The phylogenetic analysis revealed four major monophyletic clades. Two clades included specimens of C. atripectoralis from the Great Barrier Reef and individuals of C. viridis from the Red Sea, respectively. The remaining individuals of C. viridis from Indonesia and the Philippines were grouped into two clades without phylogeographic structure. The obtained results (1) verified that C. viridis and C. atripectoralis are distinct species and (2) revealed three deep evolutionary lineages of C. viridis in the Indo-Malay Archipelago and the Red Sea. # 2008 The Authors

Behavioural discrimination of polarized light in the damselfish Chromis viridis (family Pomacentridae).
In this study, we demonstrate the capacity for damselfish (green chromis, Chromis viridis) to discriminate between different e-vector orientations of ultraviolet polarized light. We examined the ability of green chromis to resolve small differences in e-vector orientation of ultraviolet polarized light. Fish were successfully trained to swim towards an e-vector orientation of polarized light us...
متن کاملSpecialization in habitat use by coral reef damselfishes and their susceptibility to habitat loss
While it is generally assumed that specialist species are more vulnerable to disturbance compared with generalist counterparts, this has rarely been tested in coastal marine ecosystems, which are increasingly subject to a wide range of natural and anthropogenic disturbances. Habitat specialists are expected to be more vulnerable to habitat loss because habitat availability exerts a greater limi...
متن کاملPatterns of morphological evolution of the cephalic region in damselfishes (Perciformes: Pomacentridae) of the Eastern Pacific
Pomacentridae are one of the most abundant fish families inhabiting reefs of tropical and temperate regions. This family, comprising 29 genera, shows a remarkable diversity of habitat preferences, feeding, and behaviours. Twenty-four species belonging to seven genera have been reported in the Eastern Pacific region. The present study focuses on the relationship between the diet and the cephalic...
متن کاملMolecular systematics of the damselfishes (Teleostei: Pomacentridae): Bayesian phylogenetic analyses of mitochondrial and nuclear DNA sequences.
Damselfishes in the family Pomacentridae represent one of the few families of reef fishes found on coral reefs irrespective of location. At a local scale, damselfishes are often the most abundant coral reef fish, and their study has provided much of our current understanding of the ecology of tropical reef animals. The study of phylogenetic relationships among the Pomacentridae has lagged ecolo...
متن کاملComparative trophic morphology in eight species of damselfishes (Pomacentridae).
Damselfishes show significant biodiversity in the coral reefs. To better understand such diversity, an ecomorphological approach was investigated in the trophic morphology of eight species of Pomacentridae (Chromis acares, C. margaritifer, Dascyllus aruanus, D. flavicaudus, Pomacentrus pavo, Plectroglyphidodon johnstonianus, Pl. lacrymatus and Stegastes nigricans) belonging to different trophic...
