Survey and Spatial Distribution of Shoreline Malacofauna in Grande Island, Subic Bay Philippine Journal of Science 139 (2): 149-159, December 2010 ISSN 0031 - 7683 Survey and Spatial Distribution of Shoreline Malacofauna in Grande Island, Subic Bay Gizelle A. Batomalaque*, Bryan Geoffrey P. Arce, Ma. Brenda M. Hernandez, and Ian Kendrich C. Fontanilla Institute of Biology, Quirino St., University of the Philippines, Diliman, Quezon City 1101 Grande Island, Subic Bay is an excellent site for studying spatial distributions on a local scale because of its topographic heterogeneity. This study aimed to provide a systematic survey and spatial distribution of shoreline malacofauna of the island using a total of 956 continuous 2 x 2 m plots. Substrate types were classified as sand, sand-pebble, rock-sand, rock-pebble, pebble- rock-coral rubble, boulder, and wood. One hundred mollusk species were identified from 44,465 individuals with 54 additional individuals still unresolved. Mollusks were found to be distributed according to the substrate type (composition and particle size) and are independent of the total area sampled. Substrates that are loose or unstable tend to have only few species while those that are compact have more species. Only bivalves were found in the sand substrate. Planaxids, nerites, trochids, and siphonarids were the dominant groups in substrates with rocks, pebbles, and coral rubble. Nudibranchs only occurred in rocky substrates. Nacellids and littorinids predominate particularly in boulders. Littorinids were also numerous in woody substrates. Juvenile trochids and planaxids were most abundant in regions with calm water while Cellana species and adult trochids were particular in areas exposed to strong currents. The morphological adaptations of different species enabled them to occur in specific habitat types.

At present, no systematic studies have been medical applications. The global estimate of described executed on the biodiversity of marine mollusks around molluscan species is 70,000 (IUCN 2004), and around Luzon as confirmed by the scarcity of published literature. 22,000 species are believed to be present in the Philippines There is, however, one study in Mindoro Island conducted (PBCPP 2002). Mollusks are the second most diverse by Berdach (1981) that focused on the inventory of marine invertebrates in the Philippines, with an estimated species gastropods in the Man and Biosphere (MAB) Reserve endemism of 2-4% (PBCPP 2002). Much of the published area in Puerto Galera where Berdach (1981) found a total information regarding Philippine molluscan species is of 343 species from 45 families.

Temporal distribution was not studied focused on regional scales according to ocean basins due to limited data-gathering time and less on local scales according to physical gradients (Vallejo 2001). Little is known of the correlation between habitat types and species composition on a smaller scale. MATERIALS AND METHODS Determining spatial distribution patterns among mollusk species is important in studying the ecology of these species. An accurate description of these patterns Species survey also provides an index for studying relationships and All five sides of the island were surveyed. Sampling was interactions between different mollusks (Springsteen and conducted from May 20 to 22 and May 26 to June 1, 2008 Leobrera 1986). These also reflect how abiotic and biotic during low tide, since the area of interest was the subtidal factors collectively affect species zonations (Azouzi et zone (zone always submerged in water even at low tide). al. 2002). Abiotic factors identified are substrate grain Systematic snorkel-surveys were done in continuous 2 x 2 m size, wave action, water content, and temperature and plots along the edge of the shoreline around nearly the whole salinity of interstitial water (water contained in crevices stretch of the island. The plots were bounded by standard and within the particles of the substrate). Among these, PVC pipes that could sink under water. A maximum of 10 De Arruda and Amaral (2003) pointed to morphodynamic minutes per plot was allotted to search for mollusks. Pebbles states (substrate types and wave action) as the primary and rocks were moved and replaced in order to thoroughly determinant of distribution patterns in environments with survey each plot. For sandy substrates, the surface was a variation of physical characteristics. Biotic factors, slightly swept or dug up for burrowing mollusks. on the other hand, include recruitment (addition of Habitat description was limited only to the type of members to the population or community), predation, substrate.

Received: 31 May 2017; Accepted: 13 July 2017; Published: 18 July 2017 Abstract: Conotoxins in the venom of cone snails (Conus spp.) are a mixture of active peptides that work as blockers, agonists, antagonists, or inactivators of various ion channels. Recently we reported a high-throughput method to identify 215 conotoxin transcripts from the Chinese tubular cone snail, C. betulinus. Here, based on the previous datasets of four transcriptomes from three venom ducts and one venom bulb, we explored ion channel-based conotoxins and predicted their related ion channel receptors. Homologous analysis was also performed for the most abundant ion channel protein, voltage-gated potassium (Kv; with Kv1.1 as the representative), and the most studied ion channel receptor, nicotinic acetylcholine receptor (nAChR; with α2-nAChR as the representative), in different animals.

Population energy budgets estimated on the assumption of steady state conditions for C. testudinaria (Linnaeus, 1758) on the rocky shore of Ohoiwait, are presented. Large difference in population structure, and hence energetics, occurred at different localities along the rocky shore. Relatively high proportions (98 %) of the assimilated energy was lost via metabolism. Assimilation efficiency is 39 %, net growth efficiency is 1.8 %, and ecological efficiency 0.3 %. Production (P), energy flow (A) and total energy consumption (C) were expressed as functions of animal size, in order to facilitate gross estimations of the energy component for which data on size frequency and density are available.

India 4Veer Wajekar Arts, Science & Commerce College, Phunde, Uran, Dist. – Raigad, Navi Mumbai, (M.S.) India Abstract Diversity of macrobenthos from Panvel creek remain poorly known. Here, the species composition and abundance of macrobenthos is explored from June 2018 to May 2019 to assess the ecological status of the creek. 18 species of macrobenthic fauna consisting of 14 genera, 12 families, 06 orders and 05 classes were recorded. The most abundant taxa were polychaetes, crustaceans, gastropods and pelecypods. Species belonging to Polynoidae, Cerithiidae, Potamididae, Neritidae and Trapezidae shows highest distribution and abundance. The creek is dominated by Perinereis cultrifera, Clypeomorus bifasciata, Potamides cingulatus, Nerita oryzarum and Neotrapezium sublaevigatum. N. sublaevigatum of the family Trapezidae from the class Bivalvia is recorded as an opportunistic taxa which exploits disturbed condition due to environmental stress. This study showed that at present though the creek is resourceful and supports the coastal marine life, is under considerable stress of anthropogenic inputs. Coastal environment of Panvel creek is deteriorating due to ongoing construction of Navi Mumbai International Airport and unplanned development activities. Present information could be helpful as a baseline data for further study of anthropogenic inputs on coastal ecosystem of Panvel creek.

  • Nansei Islands Biological Diversity Evaluation Project Report 1 Chapter 1
    Introduction WWF Japan’s involvement with the Nansei Islands can be traced back to a request in 1982 by Prince Phillip, Duke of Edinburgh. The “World Conservation Strategy”, which was drafted at the time through a collaborative effort by the WWF’s network, the International Union for Conservation of Nature (IUCN), and the United Nations Environment Programme (UNEP), posed the notion that the problems affecting environments were problems that had global implications. Furthermore, the findings presented offered information on precious environments extant throughout the globe and where they were distributed, thereby providing an impetus for people to think about issues relevant to humankind’s harmonious existence with the rest of nature. One of the precious natural environments for Japan given in the “World Conservation Strategy” was the Nansei Islands. The Duke of Edinburgh, who was the President of the WWF at the time (now President Emeritus), naturally sought to promote acts of conservation by those who could see them through most effectively, i.e. pertinent conservation parties in the area, a mandate which naturally fell on the shoulders of WWF Japan with regard to nature conservation activities concerning the Nansei Islands. This marked the beginning of the Nansei Islands initiative of WWF Japan, and ever since, WWF Japan has not only consistently performed globally-relevant environmental studies of particular areas within the Nansei Islands during the 1980’s and 1990’s, but has put pressure on the national and local governments to use the findings of those studies in public policy. Unfortunately, like many other places throughout the world, the deterioration of the natural environments in the Nansei Islands has yet to stop.

    PHYLOGENY AND HISTORICAL BIOGEOGRAPHY OF LIMPETS OF THE ORDER PATELLOGASTROPODA BASED ON MITOCHONDRIAL DNA SEQUENCES TOMOYUKI NAKANO AND TOMOWO OZAWA Department of Earth and Planetary Sciences, Nagoya University, Nagoya 464-8602,Japan (Received 29 March 2003; accepted 6June 2003) ABSTRACT Using new and previously published sequences of two mitochondrial genes (fragments of 12S and 16S ribosomal RNA; total 700 sites), we constructed a molecular phylogeny for 86 extant species, covering a major part of the order Patellogastropoda. There were 35 lottiid, one acmaeid, five nacellid and two patellid species from the western and northern Pacific; and 34 patellid, six nacellid and three lottiid species from the Atlantic, southern Africa, Antarctica and Australia. Emarginula foveolata fujitai (Fissurellidae) was used as the outgroup. In the resulting phylogenetic trees, the species fall into two major clades with high bootstrap support, designated here as (A) a clade of southern Tethyan origin consisting of superfamily Patelloidea and (B) a clade of tropical Tethyan origin consisting of the Acmaeoidea. Clades A and B were further divided into three and six subclades, respectively, which correspond with geographical distributions of species in the following genus or genera: (AÍ) north­ eastern Atlantic (Patella ); (A2) southern Africa and Australasia ( Scutellastra , Cymbula-and Helcion)', (A3) Antarctic, western Pacific, Australasia ( Nacella and Cellana); (BÍ) western to northwestern Pacific (.Patelloida); (B2) northern Pacific and northeastern Atlantic ( Lottia); (B3) northern Pacific (Lottia and Yayoiacmea); (B4) northwestern Pacific ( Nipponacmea); (B5) northern Pacific (Acmaea-’ânà Niveotectura) and (B6) northeastern Atlantic ( Tectura). Approximate divergence times were estimated using geo­ logical events and the fossil record to determine a reference date.
