In the ancillariid genus Amalda, the shell is character rich and 96 described species are currently treated as valid. Based on shell morphology, several subspecies have been recognized within Amalda hilgendorfi, with a combined range extending at depths of 150–750 m from Japan to the South-West Pacific. A molecular analysis of 78 specimens from throughout this range shows both a weak geographical structuring and evidence of gene flow at the regional scale.

  • State of the Environment Rocky Shore Monitoring Report 2015-2017
    State of the Environment Rocky Shore Monitoring Report 2015-2017 Technical Report 2017-79 Taranaki Regional Council Private Bag 713 ISSN: 1178-1467 (Online) STRATFORD Document: 1845984 (Word) Document: 1918743 (Pdf) October 2017 Executive summary Section 35 of the Resource Management Act 1991 requires local authorities to undertake monitoring of the region’s environment, including land, air, marine and freshwater. The rocky shore component of the State of the Environment Monitoring (SEM) programme for Taranaki was initiated by the Taranaki Regional Council in the 1994-1995 monitoring year and has subsequently continued each year. This report covers the state and trends of intertidal hard shore communities in Taranaki. As part of the SEM programme, six representative reef sites were monitored twice a year (spring and summer surveys) using a fixed transect, random quadrat survey design. For each survey, a 50 m transect was laid parallel to the shore and substrate cover, algal cover and animal cover/abundance in 25 x 0.25 m2 random quadrats were quantified. Changes in the number of species per quadrat (species richness) and Shannon-Wiener index per quadrat (diversity) were assessed at the six reef sites over the 23 years of the SEM programme (spring 1994 to summer 2017). Of the six sites surveyed, the intertidal communities at Manihi (west Taranaki) were the most species rich (median = 19.4 species per quadrat) and diverse (median Shannon Wiener index = 1.05 per quadrat) due to the low supply of sand and the presence of pools that provided a stable environment with many ecological niches. The intertidal communities at Waihi (south Taranaki) were the least species rich (median = 11.5 species per quadrat) and diverse (median Shannon Wiener index = 0.84 per quadrat) due to the high energy wave environment, lack of stable habitat and periodic sand inundation.

Av. Benavides 5400, Surco. P.O. Box 18-131. Lima, Perú. Abstract: Peru is an ecologically diverse country, with 84 life zones in the Holdridge system and 18 ecological regions (including two marine). 1910 molluscan species have been recorded. The highest number corresponds to the sea: 570 gastropods, 370 bivalves, 36 cephalopods, 34 polyplacoforans, 3 monoplacophorans, 3 scaphopods and 2 aplacophorans (total 1018 species). The most diverse families are Veneridae (57spp.), Muricidae (47spp.), Collumbellidae (40 spp.) and Tellinidae (37 spp.). Biogeographically, 56 % of marine species are Panamic, 11 % Peruvian and the rest occurs in both provinces; 73 marine species are endemic to Peru. Land molluscs include 763 species, 2.54 % of the global estimate and 38 % of the South American esti- mate. The most biodiverse families are Bulimulidae with 424 spp., Clausiliidae with 75 spp. and Systrophiidae with 55 spp. In contrast, only 129 freshwater species have been reported, 35 endemics (mainly hydrobiids with 14 spp. The paper includes an overview of biogeography, ecology, use, history of research efforts and conser- vation; as well as indication of areas and species that are in greater need of study.

  • THE LISTING of PHILIPPINE MARINE MOLLUSKS Guido T
    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.

  • Gofas XP 95-104
    Bollettino Malacologico, Roma, 39 (5-8): 95-104, [2003] 2004 - Società Italiana di Malacologia Nomenclature of the smaller Mediterranean Cerithium species Serge Gofas, Vittorio Garilli & Marie-Catherine Boisselier-Dubayle KEY WORDS: Cerithiidae, Mediterranean, taxonomy, lectotype designations. ABSTRACT The Mediterranean morphotypes generally confused under the name Cerithium rupestre have been shown to belong to two different species. The cor- rect name for one of the species, living in very shallow rocky areas including splashpools, is Cerithium lividulum Risso,1826, and for the other, usual- ly living in the shallow infralittoral community of photophilous algae, C. renovatum Monterosato, 1884. Type material is figured for all nominal species in this species group introduced prior to 1900, and for some of the species proposed later. Orientations for future work in the taxonomy of this species group are suggested. RIASSUNTO E’ stato mostrato che le entità morfologiche generalmente confuse sotto il nome Cerithium rupestre appartengono a due specie distinte. I nomi corretti per questi taxa sono Cerithium lividulum Risso, 1826, per la specie vivente su fondali rocciosi in acque più superficiali dell’infralitorale superiore e nelle pozze di marea, e Cerithium renovatum Monterosato, 1884, per la specie solitamente vivente su fondali infralitorali ricoperti da alghe fotofile. Cerithium lividulum ha una conchiglia robusta con giri appena convessi, coste assiali talora tuberculate e cordoni spirali piani. La colorazione è data da screziature bruno-verdastre decorrenti spiralmente su uno sfondo bianco. La conchiglia di Cerithium renovatum è più piccola (inferiore ai 20 mm nel materiale esaminato), più delicata e snella, e presenta una serie regolare di tubercoli, costantemente di colore bianco, che iniziano nei primi giri e raggiungono il loro massimo sviluppo in corrispondenza del penultimo.

  • 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.
