Multidimensional polarization sensitivity in damselfishes
Journal of Comparative Physiology A, 2003Using electroretinogram recording and microspectrophotometry we investigated spectral sensitivity and ultraviolet polarization sensitivity in three species of coral reef fishes commonly known as damselfishes. Here we show that three species of damselfishes (three-spot damselfish, Dascyllus trimaculatus; blacktail damselfish, D.

Progression of Infection and Tumor Development in Damselfish
Marine Biotechnology, 2001The bicolor damselfish (Stegastes partitus) is a tropical marine teleost naturally affected by multiple neurofibromas and chromatophoromas on South Florida reefs. Damselfish neurofibromatosis is a transmissible disease caused by a subcellular agent. Development of tumors is associated with the appearance of a series of extrachromosomal DNAs ranging in ...

Acta ethologica, 2001
Juveniles of Stegastes nigricans occur in adult colonies, solitarily, and occasionally in juvenile colonies. We concentrated on solitary juveniles and those in adult colonies. We examined the costs and benefits of different settlement strategies, quantified the territory requirements of adults, and investigated the process of how juveniles make the ...

Kin recognition in embryonic damselfishes
Oikos, 2017Predator‐induced mortality rates are highest in early life stages; therefore, early recognition of threats can greatly increase survival chances. Some species of coral reef fishes have been frequently found to recruit back to their natal reefs; in this instance, there is a high chance of juveniles encountering their siblings, among

Territorial boundaries of the male beaugregory damselfish
Journal of Fish Biology, 2000On six separate occasions during a two month period, there were no significant differences in mean attack distances by territorial male beaugregory damselfish Stregastes leucostictus against male conspecifics, bluehead wrasse Thalassoma bifasciatus and striped parrotfish Scarus iserti.

Habitat-Limited Recruitment of Coral Reef Damselfish
Ecology, 2000Spatial variation in abundance of reef fishes with dispersing larvae often has been attributed to variation in the supply of new colonists from the plankton, which we term “supply determination.” We conducted field experiments with three species of planktivorous damselfishes (Dascyllus flavicaudus, D.

Monophyletic origin of brood care in damselfishes
Molecular Phylogenetics and Evolution, 2011The absence of a pelagic larval stage and brood care has evolved very few times in coral reef fishes. Damselfishes, a widely represented group with more than 380 species, includes only three such species, the monotypic Acanthochromis polyacanthus, and the two Altrichthys species, Altrichthys azurelineatus and Altrichthys curatus.
