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.

    A survey of fishes associated with Hawaiian deep-water Halimeda kanaloana (Bryopsidales: Halimedaceae) and Avrainvillea sp. (Bryopsidales: Udoteaceae) meadows Ross C. Langston1 and Heather L. Spalding2 1 Department of Natural Sciences, University of Hawai`i- Windward Community College, Kane`ohe,¯ HI, USA 2 Department of Botany, University of Hawai`i at Manoa,¯ Honolulu, HI, USA ABSTRACT The invasive macroalgal species Avrainvillea sp. and native species Halimeda kanaloana form expansive meadows that extend to depths of 80 m or more in the waters off of O`ahu and Maui, respectively. Despite their wide depth distribution, comparatively little is known about the biota associated with these macroalgal species. Our primary goals were to provide baseline information on the fish fauna associated with these deep-water macroalgal meadows and to compare the abundance and diversity of fishes between the meadow interior and sandy perimeters. Because both species form structurally complex three-dimensional canopies, we hypothesized that they would support a greater abundance and diversity of fishes when compared to surrounding sandy areas. We surveyed the fish fauna associated with these meadows using visual surveys and collections made with clove-oil anesthetic. Using these techniques, we recorded a total of 49 species from 25 families for H. kanaloana meadows and surrounding sandy areas, and 28 species from 19 families for Avrainvillea sp. habitats. Percent endemism was 28.6% and 10.7%, respectively. Wrasses (Family Labridae) were the most speciose taxon in both habitats (11 and six species, respectively), followed by gobies for H. kanaloana (six Submitted 18 November 2016 species). The wrasse Oxycheilinus bimaculatus and cardinalfish Apogonichthys perdix Accepted 13 April 2017 were the most frequently-occurring species within the H.

  • Microdesmidae)
    BULLETIN OF MARINE SCIENCE, 70(1): 33–39, 2002 TAXONOMY AND ZOOGEOGRAPHY OF MICRODESMUS CARRI GILBERT (MICRODESMIDAE) Felipe Amaya, Arturo Acero P. and María M. Criales ABSTRACT This contribution describes juvenile specimens of the cienaga wormfish Microdesmus carri (Microdesmidae) collected at the entrance of the estuarine lagoon Ciénaga Grande de Santa Marta on the Colombian Caribbean. This is the first report of M. carri for South American waters and the third of the species since it was originally described from the Caribbean coast of Costa Rica and later reported for Belize and the Gulf of Mexico. Meristic and morphometric data of the Colombian material are similar to those described for Costa Rica but differences from the Belize and Gulf of Mexico material were found in the fin counts. The species is considered here a southern Caribbean endemic, whose distribution may be explained by geological and oceanographic factors. The gobioid fish family Microdesmidae is widespread in marine tropical waters and includes two subfamilies: Microdesminae (wormfishes) and Ptereleotrinae (dartfishes or firefishes) (Nelson, 1994). However, Thacker (2000) excluded the dartfishes from the Microdesmidae. Wormfishes burrow in soft muddy and sandy bottoms in shelf ecosys- tems from coral reefs to estuaries and from tidepools to about 40 m depth (Robins et al., 1986; Nelson, 1994). Seven species of wormfishes have been described for the western Atlantic, two in the genus Cerdale (C. fasciata and C. floridana) (Dawson, 1974) and five in the genus Microdesmus (M. bahianus, M. lanceolatus, M. longipinnis, M. lucus and M. carri) (Gilbert, 1966; Dawson, 1977). The only wormfish previously recorded from the Colombian Caribbean is C.

Bellwood IUCN RESILIENCE SCIENCE GROUP WORKING PAPER SERIES - NO 7 IUCN Global Marine Programme Founded in 1958, IUCN (the International Union for the Conservation of Nature) brings together states, government agencies and a diverse range of non-governmental organizations in a unique world partnership: over 100 members in all, spread across some 140 countries. As a Union, IUCN seeks to influence, encourage and assist societies throughout the world to conserve the integrity and diversity of nature and to ensure that any use of natural resources is equitable and ecologically sustainable. The IUCN Global Marine Programme provides vital linkages for the Union and its members to all the IUCN activities that deal with marine issues, including projects and initiatives of the Regional offices and the six IUCN Commissions. The IUCN Global Marine Programme works on issues such as integrated coastal and marine management, fisheries, marine protected areas, large marine ecosystems, coral reefs, marine invasives and protection of high and deep seas. The Nature Conservancy The mission of The Nature Conservancy is to preserve the plants, animals and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive. The Conservancy launched the Global Marine Initiative in 2002 to protect and restore the most resilient examples of ocean and coastal ecosystems in ways that benefit marine life, local communities and economies.
