  • Teleostei: Perciformes: Leiognathidae): Phylogeny, Taxonomy, and Description of a New Species
    CORE Metadata, citation and similar papers at core.ac.uk Provided by American Museum of Natural History Scientific Publications PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK, NY 10024 Number 3459, 21 pp., 8 ®gures, 2 tables October 28, 2004 A Clade of Non-Sexually Dimorphic Pony®shes (Teleostei: Perciformes: Leiognathidae): Phylogeny, Taxonomy, and Description of a New Species JOHN S. SPARKS1 AND PAUL V. DUNLAP 2 ABSTRACT A phylogeny was generated for Leiognathidae, commonly known as pony®shes, using nu- cleotide characters from two mitochondrial genes. Results indicate that Leiognathidae com- prises two major clades, one consisting of species that exhibit internally sexually dimorphic light-organ systems (LOS), and the Leiognathus equulus species complex, whose members exhibit neither internal nor external sexual dimorphism of the LOS. Species with internally sexually dimorphic LOS generally also exhibit associated male-speci®c external modi®cations in the form of transparent patches on the margin of the opercle, the midlateral ¯ank, or behind the pectoral ®n axil. The L. equulus species complex is the sister group to all other leiog- nathids, and a new species, L. robustus, recovered within this clade is described herein. Results demonstrate that Leiognathus is paraphyletic, whereas Gazza and Secutor are each monophy- letic and are nested within the sexually dimorphic clade. The morphology of the LOS of non- sexually dimorphic leiognathids is compared to the more common sexually dimorphic state, and differences in these systems are discussed and illustrated. In the context of a family-level phylogeny, we can trace the evolution of the leiognathid LOS from a ``simple'' non-sexually dimorphic circumesophageal light organ to a complex and species-speci®c luminescence sys- tem involving not only major structural modi®cations of the light organ itself but also nu- merous associated tissues.

BAUN Abstract Sardines (Clupeidae) make up a substantial proportion of the fish catch across the Philippines and consequently are the most accessible source of animal protein for millions of Filipinos. Further, this fishery is an economic engine providing thousands of jobs and generating revenue at the individual, municipal, and national levels. Ecologically, sardines are basally positioned in a food web that supports pelagic tuna and mackerel, as well as numerous sea birds and marine mammals. Philippine sardine biodiversity is among the highest in the world and includes the only known freshwater sardine species.

The South China Sea is a major water body containing a large and diverse fish fauna. However, many areas of the South China Sea, particularly in Malaysia and Vietnam, have been poorly studied in terms of fish taxonomy and diversity. Local fish scientists and students have frequently faced difficulty when try- ing to identify fishes in their home countries.

  • Parasites of Coral Reef Fish: How Much Do We Know? with a Bibliography of Fish Parasites in New Caledonia
    Belg. J. Zool., 140 (Suppl.): 155-190 July 2010 Parasites of coral reef fish: how much do we know? With a bibliography of fish parasites in New Caledonia Jean-Lou Justine (1) UMR 7138 Systématique, Adaptation, Évolution, Muséum National d’Histoire Naturelle, 57, rue Cuvier, F-75321 Paris Cedex 05, France (2) Aquarium des lagons, B.P. 8185, 98807 Nouméa, Nouvelle-Calédonie Corresponding author: Jean-Lou Justine; e-mail: [email protected] ABSTRACT. A compilation of 107 references dealing with fish parasites in New Caledonia permitted the production of a parasite-host list and a host-parasite list. The lists include Turbellaria, Monopisthocotylea, Polyopisthocotylea, Digenea, Cestoda, Nematoda, Copepoda, Isopoda, Acanthocephala and Hirudinea, with 580 host-parasite combinations, corresponding with more than 370 species of parasites. Protozoa are not included. Platyhelminthes are the major group, with 239 species, including 98 monopisthocotylean monogeneans and 105 digeneans. Copepods include 61 records, and nematodes include 41 records. The list of fish recorded with parasites includes 195 species, in which most (ca. 170 species) are coral reef associated, the rest being a few deep-sea, pelagic or freshwater fishes. The serranids, lethrinids and lutjanids are the most commonly represented fish families. Although a list of published records does not provide a reliable estimate of biodiversity because of the important bias in publications being mainly in the domain of interest of the authors, it provides a basis to compare parasite biodiversity with other localities, and especially with other coral reefs. The present list is probably the most complete published account of parasite biodiversity of coral reef fishes.
