Pacific Plate Biogeography, with Special Reference to Shorefishes
Pacific Plate Biogeography, with Special Reference to Shorefishes VICTOR G. 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. -

The most diverse order was perciformes with 175 species, 100 genera and 43 families. The top four families with the highest number of species were gobidae (28 species), carangidae (23 species), engraulidae (15 species) and lutjanidae (14 species). Conservation status of all taxa includes one species as endangered, five species as vulnerable, 14 near threatened, 93 least concern and 16 data deficient.

The two alien species constitute very rare occurrences in the Mediterranean; the first record of H. intermedius dates back to 2002 and only a few P. indicus individuals were collected between the 1950s and 1970s. Their presence in the Mediterranean is discussed as well as possible future trends in light of recent environmental changes.

Gilbertese and Ellice Islander Names for Fishes and Other Organisms
Gilbertese and Ellice Islander Names for Fishes and Other Organisms PHIL S. LOBEL Museum of Comparative Zoology Har vard University Cambridge. Massachusel/s 02138 Abstract.- A compilation of 254 Gilbertese and 153 Ellice Island~r fish names is given which includes names for species from sixty families of fishes. The Gilbertese names (25) and Ellice Islander names ( 17) are also given for anatomical parts of fishes. Gilbertese names for lizards (3), marine invertebrates (95) and algae (2) are listed. The names were compiled from the literature and from interviews with Gilbertese and Ellice Islander fisherman living on Fanning Island in the Line Islands. Introduction Names used by Pacific Islanders for fishes are well known only for Hawaiians (Titcomb, 1953), Tahitians (Randall, 1973) and Palauans (Helfman and Randall, 1973). Banner and Randall (1952) and Randall (1955) have reported some Gilbertese names for invertebrates and fishes, but these were relatively few. A listing ofGilbertese names for plants and animals was compiled from the literature by Goo and Banner ( 1963), but unfortunately this work was never published. To my knowledge, no lists of Ellice Islander names have yet been published. I have compiled the common names used by the people of Fanning Atoll, Line Islands. The people are of Gilbertese and Ellice Islander descent having been brought to the Atoll within the last 50 years to work for the copra plantation. In addition, I have included previously published names to make this listing as complete as possible. I add about 200 new Gilbertese and 150 Ellice Islander names. I have not included names for terrestrial plants (see Moul 1957 for these). -

Competition and distribution model predictions vary based on dominance hierarchies, but most assume differences in dominance are constant across habitats. More recent evidence suggests dominance and competitive advantages may vary based on habitat. We quantified dominance interactions between two species of sharks Carcharhinus amblyrhynchos and Carcharhinus melanopterus, across two different habitats, fore reef and back reef, at a remote Pacific atoll. We used Baited Remote Underwater Video (BRUV) to observe dominance behaviors and quantified the number of aggressive interactions or bites to the BRUVs from either species, both separately and in the presence of one another. Blacktip reef sharks were the most abundant species in either habitat, and there was significant negative correlation between their relative abundance, bites on BRUVs, and the number of grey reef sharks. Although this trend was found in both habitats, the decline in blacktip abundance with grey reef shark presence was far more pronounced in fore reef habitats. We show that the presence of one shark species may limit the feeding opportunities of another, but the extent of this relationship is habitat specific. Future competition models should consider habitat-specific dominance or competitive interactions.
