  • (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: the Genera Nodilittorina, Austrolittorina and Afrolittorina
    © Copyright Australian Museum, 2004 Records of the Australian Museum (2004) Vol. 56: 75–122. ISSN 0067-1975 The Subfamily Littorininae (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: The Genera Nodilittorina, Austrolittorina and Afrolittorina DAVID G. REID* AND SUZANNE T. WILLIAMS Department of Zoology, The Natural History Museum, London SW7 5BD, United Kingdom [email protected] · [email protected] ABSTRACT. The littorinine gastropods of the temperate southern continents were formerly classified together with tropical species in the large genus Nodilittorina. Recently, molecular data have shown that they belong in three distinct genera, Austrolittorina, Afrolittorina and Nodilittorina, whereas the tropical species are members of a fourth genus, Echinolittorina. Austrolittorina contains 5 species: A. unifasciata in Australia, A. antipodum and A. cincta in New Zealand, and A. fernandezensis and A. araucana in western South America. Afrolittorina contains 4 species: A. africana and A. knysnaensis in southern Africa, and A. praetermissa and A. acutispira in Australia. Nodilittorina is monotypic, containing only the Australian N. pyramidalis. This paper presents the first detailed morphological descriptions of the African and Australasian species of these three southern genera (the eastern Pacific species have been described elsewhere). The species-level taxonomy of several of these has been confused in the past; Afrolittorina africana and A. knysnaensis are here distinguished as separate taxa; Austrolittorina antipodum is a distinct species and not a subspecies of A. unifasciata; Nodilittorina pyramidalis is separated from the tropical Echinolittorina trochoides with similar shell characters. In addition to descriptions of shells, radulae and reproductive anatomy, distribution maps are given, and the ecological literature reviewed.

Ser. / Reproduction of the Continuously Breeding Tropical Hermit Crab Clibanarius clibanarius Sudha Varadarajan* and T. Subramoniam Department of Zoology, University of Madras, Madras 600005,India ABSTRACT: On the Indian east coast, the hermit crab Clibanarius clibanarius breeds continuously with peak activity from September to January, corresponding to the onset of the retreating monsoon. Individuals within the population breed asynchronously and vary widely in their carapace lengths. probably because of steady, year-round recruitment. Our data on reproduction emphasize the flexible use of an apparently stable, tropical environment by these crabs. INTRODUCTION 18 m. In January and February, 1976 and January, 1977 all crabs were scarce and few could be collected. In tropical marine waters, where sea temperatures Females, smaller in size than males, often occupied fluctuate little seasonally, many invertebrates are smaller gastropod shells of different species of Murex, known to reproduce throughout the year (Giese and Bursa, Babylonia or Turitella. After removal from the Pearse, 1974). In Indian waters a major factor that shell, the length from the tip of the rostrum to the influences intertidal as well as offshore forms is the posterior indentation on the mid-dorsal line of the monsoon rain that differs in time and intensity on the cephalothorax was taken as carapace length.

  • The Chiton Radula: a Unique Model for Biomineralization Studies
    4 The Chiton Radula: A Unique Model for Biomineralization Studies Lesley R. Brooker1 and Jeremy A. Shaw2 1University of the Sunshine Coast 2Centre for Microscopy, Characterisation & Analysis University of Western Australia Australia 1. Introduction Over the course of evolution, a range of strategies have been developed by different organisms to produce unique materials and structures perfected for their specific function. This biological mastery of materials production has inspired the birth of the new discipline of biomaterials through biomimicry (Birchall, 1989). Chitons (Mollusca: Polyplacophora) are slow moving, bilaterally symmetrical and dorso- ventrally flattened molluscs that are commonly found on hard substrata in intertidal regions of coastlines around the world (Kaas & Jones, 1998). All species are characterized by a series of eight dorsal, articulating shell plates or valves, which may be embedded, to varying degrees, in a fleshy, muscular girdle (Kaas & Jones, 1998) (Figure 1). Approximately 750 living species are known, and while intertidal regions are home to the majority of chitons, a number of species can be found at depths of up to 8000m where they feed on detrital material (Kaas & Jones, 1998). Fig. 1. Photograph of the dorsal surface of the chiton Acanthopleura gaimardi, showing the eight overlapping aragonite plates surrounded by the fleshy girdle, which, in this species, is covered in small aragonite spines. Chitons feed by rasping macro- and micro-algae from the rocks on which they live through the use of a radula. The radula has been coined as a conveyor belt of continuously developing www.intechopen.com 66 Advanced Topics in Biomineralization teeth, replaced by new teeth as they are worn and lost.

  • Taxonomy of Tropical West African Bivalves V. Noetiidae
    Bull. Mus. nati. Hist, nat., Paris, 4' sér., 14, 1992, section A, nos 3-4 : 655-691. Taxonomy of Tropical West African Bivalves V. Noetiidae by P. Graham OLIVER and Rudo VON COSEL Abstract. — Five species of Noetiidae are described from tropical West Africa, defined here as between 23° N and 17°S. The Noetiidae are represented by five genera, and four new taxa are introduced : Stenocista n. gen., erected for Area gambiensis Reeve; Sheldonella minutalis n. sp., Striarca lactea scoliosa n. subsp. and Striarca lactea epetrima n. subsp. Striarca lactea shows considerable variation within species. Ecological factors and geographical clines are invoked to explain some of this variation but local genetic isolation could not be excluded. The relationships of the shallow water West African noetiid species are analysed and compared to the faunas of the Mediterranean, Caribbean, Panamic and Indo- Pacific regions. Stenocista is the only genus endemic to West Africa. A general discussion on the relationships of all the shallow water West African Arcoidea is presented. The level of generic endemism is low and there is clear evidence of circumtropical patterns of similarity between species. The greatest affinity is with the Indo-Pacific but this pattern is not consistent between subfamilies. Notably the Anadarinae have greatest similarity to the Panamic faunal province. Résumé. — Description de cinq espèces de Noetiidae d'Afrique occidentale tropicale, ici définie entre 23° N et 17° S. Les Noetiidae sont représentés par cinq genres.

  • The Haifa–Beirut–Tripoli Railway
    APPENDIX 2 THE HAIFA–BEIRUT–TRIPOLI RAILWA Y By A. E. FIEL D Syria does not lend itself easily to railway construction . Very little such work was undertaken between the two world wars. In 1940, however, the possibility of Allied occupation of the Lebanon, and the hope that Turke y would join the Allies, made it very desirable that there should be a direct link between the standard gauge line from the British bases i n Egypt and Palestine then terminating at Haifa, and the northern Syrian system ending at Tripoli . Earlier the French administration had considered the linking of Haifa and Tripoli by a route along the coast, but the project had been shelved for fear that the port of Haifa would benefit at the expense of Beirut. In 1940 and 1941 Middle East Command had surveys made of various routes as far as the Lebanon border . From a map study the first route favoured was from Haifa round the north o f the Sea of Galilee to Rayak where the proposed railway would join th e Homs-Aleppo-Turkey standard gauge line . This was ruled out because it involved very heavy cutting in basalt . The next possibility considered was an extension of the line northwards from Haifa along the coast to th e Litani River and thence inland to Metulla-Rayak, but the route could not be explored before the conquest of Syria in July 1941 . It then became evident that much heavy bridge work would be necessary in the Litani gorges which would not be economically justifiable as a wartime project .

  • Pagurid Crabs (Decapoda Anomura) from St
    PAGURID CRABS (DECAPODA ANOMURA) FROM ST. JOHN, VIRGIN ISLANDS, WITH DESCRIPTIONS OF THREE NEW SPECIES 1) BY ANTHONY J. PROVENZANO, Jr. Institute of Marine Science,University of Miami, Florida, U.S.A. INTRODUCTION As part of a survey of the marine fauna and flora of the recently established U. S. Virgin Islands National Park at St. John, a series of collections have been made by Marine Laboratory personnel. Among the Crustacea taken were a number of new records for the Virgin Islands, including three species not referable to any yet named. The present report deals with the hermit crabs of the families Diogenidae and Paguridae; these families corresponding to those of MacDonald, Pike & Williamson ( 1 9 5 7 ) . Synonymies are restricted to the original description and one or more references usually containing more complete information. Size of specimens where given refers to carapace length. The station numbers refer to records kept by Herman Kumpf while at St. John; the field data being on file in the Marine Laboratory Museum. Unless otherwise noted, the general locality for material examined is St. John. Holotypes are deposited in the U. S. National Museum, while most of the remaining material is deposited in the University of Miami Marine Laboratory Museum (UMML). The writer is indebted to Dr. Marvin L. Wass of the Virginia Fisheries Labora- tory for examining the three new species and for comments incorporated in the manuscript. He would also like to thank Dr. John Randall and his co-workers who made special efforts to collect hermit crabs during their general field studies.

Based on literature records and original samples, we review here the knowledge of the Lebanese marine bivalve biota, tracing its changes during the last 170 yr. The updated checklist of bivalves of Lebanon yielded a total of 114 species (96 native and 18 alien taxa), accounting for ca. 26.5% of the known Mediterranean Bivalvia and thus representing a particularly poor fauna. Analysis of the 21 taxa historically described on Lebanese material only yielded 2 available names. Records of 24 species are new for the Lebanese fauna, and Lioberus ligneus is also a new record for the Mediterranean Sea. Comparisons between molluscan records by past (before 1950) and modern (after 1950) authors revealed temporal variations and qualitative modifications of the Lebanese bivalve fauna, mostly affected by the introduction of Erythraean species. The rate of recording of new alien species (evaluated in decades) revealed later first local arrivals (after 1900) than those observed for other eastern Mediterranean shores, while the peak in records in conjunc- tion with our samplings (1991 to 2010) emphasizes the need for increased field work to monitor their arrival and establishment.
