Relationships Between Otolith Size and Body Size for Hawaiian Reef Fishes1 Relationships between Otolith Size and Body Size for Hawaiian Reef Fishes1 Ken Longenecker2 Abstract: Estimating body size of fishes from remains recovered from pisci- vores, archaeological sites, and sedimentary deposits is desirable but rarely ac- complished because the relationships between the size of a fish and its durable anatomical structures are largely unknown. Regression equations to predict the size or weight of 41 common Hawaiian reef fishes from sagittae (saccular oto- liths) are presented. Data are also grouped into higher taxa to permit size pre- dictions when otoliths cannot be assigned to species.

SPRINGER m SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 367 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoo/ogy Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world cf science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.

Our understanding of their evolutionary ecology, morphology and function has often been advanced by increasingly detailed and accurate molecular phylogenies. Here we present the next stage of multi-locus, molecular phylogenetics for the group based on analysis of 12 nuclear and mitochondrial gene sequences from 330 of the 422 damselfish species.

Endemic marine species at remote oceanic islands provide opportunities to investigate the proposed correlation between range size and dispersal ability. Because these species have restricted geographic ranges, it is assumed that they have limited dispersal ability, which consequently would be refected in high population genetic structure. To assess this relationship at a small scale and to determine if it may be related to specifc reef fsh families, here we employ a phylogeographic survey of three endemic Hawaiian damselfshes: Abudefduf abdominalis, Chromis ovalis,andChromis verater.

Bicolour damselfish, Stegastes partitus. [http://reefguide.org/carib/bicolordamsel.html, downloaded 14 March 2015] TRAITS. Stegastes partitus is one of the five most commonly found fishes amongst the coral reefs within Trinidad and Tobago. Length: total length in males and females is 10cm (Rainer, n.d.). Contains a total of 12 dorsal spines and 14-17 dorsal soft rays in addition to a total of 2 anal spines and 13-15 anal soft rays. A blunt snout is present on the head with a petite mouth and outsized eyes. Colour: Damsels show even distribution of black and white coloration with a yellow section separating both between the last dorsal spine and the anal fin (Fig. 1), however during mating, males under differentiation in their coloration (Schultz, 2008). There are colour variations depending on the geographic region and juveniles differ from the adults. UWI The Online Guide to the Animals of Trinidad and Tobago Ecology DISTRIBUTION. Distribution is spread throughout the western Atlantic (Fig. 2), spanning from Florida to the Bahamas and the Caribbean with possible extension to Brazil (Rainer, n.d.). They are also found along the coast of Mexico. HABITAT AND ACTIVITY. Found at a depth of approximately 30m, damsels are found in habitats bordering coral reefs, that is areas of dead coral, boulders and man-made structures where algae is most likely to grow.

Habitat, biology, and fisheries: Cirrhitids are bottom-dwelling fishes of coral reefs or rocky substrata; the majority occur in shallow water. They use their thickened lower pectoral-fin rays to wedge themselves in position in areas subject to surge. All species are carnivorous, feeding mainly on benthic crustaceans.

Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region.
