The Status of Mollusk Diversity and Physical Setting of the Mangrove Zones in Catanduanes Island, Luzon, Philippines
BIOTROPIA Vol. 17 No. 2, 2010: 62 - 76 THE STATUS OF MOLLUSK DIVERSITY AND PHYSICAL SETTING OF THE MANGROVE ZONES IN CATANDUANES ISLAND, LUZON, PHILIPPINES JIMMY T. MASAGCA1,2 ANGELICA V. MENDOZA² and ESTRELLA T. TRIBIANA² ¹Pacific Island Institute for Pedagogy, Technology, Arts & Sciences, Inc. De La Salle University-Dasmarinas,~ Philippines ²Catanduanes State Colleges, Calatagan, Virac 4800, Catanduanes, Philippines Received 06 August 2010 / Accepted 13 September 2010 ABSTRACT The status of mollusk diversity and physical setting of mangrove areas in Catanduanes island, Luzon (Philippines) are described. A total of 57 species of mollusks, consisting of 27 gastropods and 30 bivalves were recorded in the island. Registering higher values of species diversity indices (Margalef) and species richness (Menhinick) are the prosobranch, Terebralia sulcata; corbiculid bivalve, Geloina coaxans; potamidiids, Cerithidea cingulata and Cerithidea rhizophorarum; and two other species of the genus Littorina (Littorinopsis). Using the physiographic model, majority of the mangrove areas under study follow the composite river and wave-dominated setting with some few areas having the wave-dominated, tide-dominated allochthonous setting. Keywords: Mollusk diversity, mangrove areas, Philippines INTRODUCTION In recent years, there had been an increased interest on the status of mangrove areas in tropical coastal ecosystems for economic and ecologic reasons (McNeely et al. 1990, Maler 1997, Masagca 2006). These are the most biologically diverse of all marine ecosystems but are being degraded worldwide by human activities potentially leading to numerous extinctions (Rios-Jara 2009). Conservation efforts targeted toward these ecosystems could help in averting the loss of tropical biodiversity. The first step according to Hamilton and Snedaker (1984) towards the attainment of the goals of conservation and sustainable use of the mangrove ecosystem is to develop data base. -
Constructional Morphology of Cerithiform Gastropods

Present address: The Kyoto University Museum, Yoshida Honmachi, Sakyo-ku, Kyoto 606-8501, Japan (email: [email protected]) Received December 19, 2005; Revised manuscript accepted May 26, 2006 Abstract. Cerithiform gastropods possess high-spired shells with small apertures, anterior canals or si- nuses, and usually one or more spiral rows of tubercles, spines or nodes. This shell morphology occurs mostly within the superfamily Cerithioidea. Several morphologic characters of cerithiform shells are adap- tive within five broad functional areas: (1) defence from shell-peeling predators (external sculpture, pre- adult internal barriers, preadult varices, adult aperture) (2) burrowing and infaunal life (burrowing sculp- tures, bent and elongated inhalant adult siphon, plough-like adult outer lip, flattened dorsal region of last whorl), (3) clamping of the aperture onto a solid substrate (broad tangential adult aperture), (4) stabilisa- tion of the shell when epifaunal (broad adult outer lip and at least three types of swellings located on the left ventrolateral side of the last whorl in the adult stage), and (5) righting after accidental overturning (pro- jecting dorsal tubercles or varix on the last or penultimate whorl, in one instance accompanied by hollow ventral tubercles that are removed by abrasion against the substrate in the adult stage). Most of these char- acters are made feasible by determinate growth and a countdown ontogenetic programme. -

Evolution, Distribution, and Phylogenetic Clumping of a Repeated Gastropod Innovation
Zoological Journal of the Linnean Society, 2017, 180, 732–754. With 5 figures. The varix: evolution, distribution, and phylogenetic clumping of a repeated gastropod innovation NICOLE B. WEBSTER1* and GEERAT J. VERMEIJ2 1Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada T6G 2E9 2Department of Earth and Planetary Sciences, University of California, Davis, CA 95616, USA Received 27 June 2016; revised 4 October 2016; accepted for publication 25 October 2016 A recurrent theme in evolution is the repeated, independent origin of broadly adaptive, architecturally and function- ally similar traits and structures. One such is the varix, a shell-sculpture innovation in gastropods. This periodic shell thickening functions mainly to defend the animal against shell crushing and peeling predators. Varices can be highly elaborate, forming broad wings or spines, and are often aligned in synchronous patterns. Here we define the different types of varices, explore their function and morphological variation, document the recent and fossil distri- bution of varicate taxa, and discuss emergent patterns of evolution. We conservatively found 41 separate origins of varices, which were concentrated in the more derived gastropod clades and generally arose since the mid-Mesozoic. Varices are more prevalent among marine, warm, and shallow waters, where predation is intense, on high-spired shells and in clades with collabral ribs. Diversification rates were correlated in a few cases with the presence of varices, especially in the Muricidae and Tonnoidea, but more than half of the origins are represented by three or fewer genera. Varices arose many times in many forms, but generally in a phylogenetically clumped manner (more frequently in particular higher taxa), a pattern common to many adaptations. -
Johannes Thiele and His Contributions to Zoology. Part 2. Genus-Group Names (Mollusca)
NEMOURIA Occasional Papers of the Delaware Museum of Natural History NUMBER 39 SEPTEMBER 30, 1991 JOHANNES THIELE AND HIS CONTRIBUTIONS TO ZOOLOGY. PART 2. GENUS-GROUP NAMES (MOLLUSCA) Kenneth J. Boss 1 and Rudiger Bieler2 ABSTRACT. This is the second part of a series on the German zoologist Johannes Thiele (1860-1935) and comprises a critical listing of the genus-group taxa which he described as new to malacology. Each of these names is accompanied by author and bibliographic references, original status, type-species with its original binominal spelling and bibliographic source and some data on subsequent taxonomic placements. Thiele introduced a total of 291 such names in the Phylum Mollusca, distributed as follows: 11 Aplacophora; 39 Polyplacophora; 200 Gastropoda (138 Prosobranchia; 20 Opisthobranchia and 42 Pulmonata); 31 Bivalvia; 10 Cephalopoda; there were no new scaphopod or monoplacophoran names. Of these, later authors recognized as valid 85 at the generic level, 110 at the subgeneric level; 71 are considered to be synonyms, and the remaining 25 are unjustified emendations or errors. INTRODUCTION As part of a series on the scientific contributions of Johannes Thiele, the eminent German zoologist, we provide here an alphabetical listing and analysis of all the genus-group taxa introduced by him in his publications on mollusks as delineated by Bieler & Boss (1989). A total of 291 names is included in the following format: (1) genus-group name; (2) author(s); (3) year of publication; (4) condensed bibliographic reference; (5) original status as given by Thiele; (6) subsequent status 1Museum of Comparative Zoology, Harvard University, Serial Publication Cambridge, Massachussetts 02138, U.S.A. -

Tel./Fax. +0435-821752 e-mail: [email protected] ABSTRACT The aim of the current study is to calculate the value of the abundance, diversity, and the density of phyla mollusks in the Tutuwoto mangrove area of Anggrek District. The survey method is used in this study as a method, which means that it collects the data directly at the research area. The observations were carried out under mangrove stands. The area of the observation plot is 5m x 5m. Phylum mollusks collected at the study site were counted by the number of individuals, abundance, diversity, and density of the types of each species. Sanon-Wienner formula is used to calculate the species diversity, Brower formula is used to calculate the density, and Odum formula is used to calculate the abundance of the species. The findings show that it is found that the reasearch about phylum mollusks in Tutuwoto mangrove area consisted of 6 (six) types namely Terebralia sulcata, Terebralia palustris, Nerita articulate, Hexaplex trunculus, Anadara granosa, and Mactra grandis. Based on the calculation of the abundance, diversity, and density of the mollusks phylum at the research site, there are several types that have the highest value.
