Research Article ECOLOGICAL STATUS OF PIRENELLA CINGULATA (GMELIN, 1791) (GASTROPOD: POTAMIDIDAE) IN MANGROVE HABITAT OF GHOGHA COAST, GULF OF KHAMBHAT, INDIA Devendra Solanki, Jignesh Kanejiya and *Bharatsinh Gohil Department of Life Sciences, Maharaja Krishnakumarsinhji Bhavnagar University, Bhavnagar 364 002 * Author for Correspondence ABSTRACT Studies on mangrove associated organisms were one of the old trends to studying mangrove ecosystems and their productivities. Seasonal status and movement of Pirenella cingulata according to habitat change studied from mangroves of Ghogha coast from December 2014 to November 2015. The maximum density (4.4/m2 area) of Pirenella cingulata reported during winter and lowest during monsoon (0.20/ m2 area). This mud snail was observed dependent on the mangrove during adverse climatic conditions during summer and monsoon seasons. Temperature and dissolved oxygen levels influence the density of P. cingulata. Keywords: Pirenella cingulata, Mangroves, Seasonal Conditions, Ghogha Coast INTRODUCTION Indo-West Pacific oceans are popular for the molluscan diversity, but despite more than two centuries of malacology, the basic knowledge about mangrove associated biota is still inadequate (Kiat, 2009). The mangroves are not only trees but itself an ecosystem comprises associated fauna, the biotope surrounded by the trees extensions like soil, stem, substrate, shade, tidal range etc., and are influential to the distribution of malacofauna (Lozouet and Plaziat, 2008). Indian coastline comprises three gulfs, namely Gulf of Kachchh and Gulf of Khambhat in west site while Gulf of Mannar in southeast side. -
Identity Crisis Or Split Personality? Trans-Ocean Distances and Not Within Individual Regions
Journal of Biogeography (J. Biogeogr.) (2007) 34, 2001–2008 GUEST Seamounts: identity crisis or split EDITORIAL personality? Craig R. McClain* Monterey Bay Aquarium Research Institute, ABSTRACT 7700 Sandholdt Road, Moss Landing, CA At present, researchers propose that over 14,000 seamounts exist and, like their 95039, USA terrestrial analogues, function like islands. In addition, seamounts are described as oases, biodiversity hotspots, and lush coral/sponge gardens. Here I discuss the extent to which these tenets regarding seamounts may be inappropriate, suffer from a lack of support, and be over-generalizations of a broad range of envi- ronmental types encountered on seamounts. Ultimately, for seamount science to progress, we need to challenge our conventional wisdom on these habitats and the extent to which all seamounts function in a similar manner. *Correspondence: Craig R.

August 2017 Guido T. Poppe A LISTING OF PHILIPPINE MARINE MOLLUSKS - V1.00 THE LISTING OF PHILIPPINE MARINE MOLLUSKS Guido T. Poppe INTRODUCTION The publication of Philippine Marine Mollusks, Volumes 1 to 4 has been a revelation to the conchological community. Apart from being the delight of collectors, the PMM started a new way of layout and publishing - followed today by many authors. Internet technology has allowed more than 50 experts worldwide to work on the collection that forms the base of the 4 PMM books. This expertise, together with modern means of identification has allowed a quality in determinations which is unique in books covering a geographical area. Our Volume 1 was published only 9 years ago: in 2008. Since that time “a lot” has changed. Finally, after almost two decades, the digital world has been embraced by the scientific community, and a new generation of young scientists appeared, well acquainted with text processors, internet communication and digital photographic skills. Museums all over the planet start putting the holotypes online – a still ongoing process – which saves taxonomists from huge confusion and “guessing” about how animals look like. Initiatives as Biodiversity Heritage Library made accessible huge libraries to many thousands of biologists who, without that, were not able to publish properly. The process of all these technological revolutions is ongoing and improves taxonomy and nomenclature in a way which is unprecedented. All this caused an acceleration in the nomenclatural field: both in quantity and in quality of expertise and fieldwork. The above changes are not without huge problematics. Many studies are carried out on the wide diversity of these problems and even books are written on the subject. -

Constructional Morphology of Cerithiform Gastropods
Paleontological Research, vol. 10, no. 3, pp. 233–259, September 30, 2006 6 by the Palaeontological Society of Japan Constructional morphology of cerithiform gastropods JENNY SA¨ LGEBACK1 AND ENRICO SAVAZZI2 1Department of Earth Sciences, Uppsala University, Norbyva¨gen 22, 75236 Uppsala, Sweden 2Department of Palaeozoology, Swedish Museum of Natural History, Box 50007, 10405 Stockholm, Sweden. 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. -
Coralliophiline Diversity at Mid-Atlantic Seamounts (Neogastropoda, Muricidae, Coralliophilinae)
BULLETIN OF MARINE SCIENCE, 79(1): 205–230, 2006 NEW TAXA PAPER CORALLIOPHILINE DIVERSITY AT MID ATLANTIC SEAMOUNTS NEOGASTROPODA, MURICIDAE, CORALLIOPHILINAE Marco Oliverio and Serge Gofas ABSTRACT Eleven species of the Coralliophilinae were identified on seamounts of the NE Atlantic and in the Azores. The species-level taxonomy is reviewed with empha- sis on the protoconch species-specific characters. The Meteor group of seamounts yielded six species (plus two unidentified), with 3–6 species found sympatrically. Babelomurex atlantidis is described as new, Coralliophila aedonia (Watson, 1886), Babelomurex sentix (Bayer, 1971) and B. dalli (Emerson and D’Attilio, 1963) are re- ported for the first time in the mid-North Atlantic. Species which were found either abundant (C. aedonia, B. sentix, B. atlantidis) or reproducing (B. dalli) are assumed to form established populations on the mid-Atlantic seamounts. In the Lusitanian group of seamounts only Gorringe yielded more than one species; all species are shared either with the European mainland or with the Canary Islands, and there is no evidence for established populations. The coralliophiline species found on the seamounts showed evidence of planktotrophic larval development; at least two are amphiatlantic, which illustrates the role of the seamounts as stepping stones in transoceanic dispersal. Some species are not known outside the seamounts, but this may be explained by the increased availability of bathyal hard bottoms rather than by limitations to dispersal. The Coralliophilinae include ca. 200 species of coral eating gastropods, distributed worldwide in tropical and temperate seas. Their placement within the family Muri- cidae, close to Rapaninae s.l. is strongly supported by molecular data (Oliverio and Mariottini, 2001a; Oliverio, Cervelli and Mariottini, 2002).
