A tale of two chitons: is habitat specialisation linked to distinct associated bacterial communities? ArchiMer
Duperron, Sebastien; Pottier, Marie-anne; Leger, Nelly; Gaudron, Sylvie M.; Puillandre, Nicolas; Le Prieur, Stephanie; Sigwart, Julia D.; Ravaux, Juliette; Zbinden, Magali.
Although most chitons (Mollusca: Polyplacophora) are shallow-water molluscs, diverse species also occur in deep-sea habitats. We investigated the feeding strategies of two species, Leptochiton boucheti and Nierstraszella lineata, recovered on sunken wood sampled in the western Pacific, close to the Vanuatu Islands. The two species display distinctly different associations with bacterial partners. Leptochiton boucheti harbours Mollicutes in regions of its gut epithelium and has no abundant bacterium associated with its gill. Nierstraszella lineata displays no dense gut-associated bacteria, but harbours bacterial filaments attached to its gill epithelium, related to the Deltaproteobacteria symbionts found in gills of the wood-eating limpet Pectinodonta sp....

Análisis tafonómico de quitones (Polyplacophora: Mollusca) holocenos de Tierra del Fuego, Argentina Ameghiniana
Gordillo,Sandra.
En el Holoceno marino de Tierra del Fuego los quitones representan una fracción menor dentro de las asociaciones de moluscos, principalmente formadas por bivalvos y gastrópodos. En este trabajo se analizan las razones de su escasa abundancia relativa. El análisis de sus atributos tafonómicos y paleontológicos indica que la condición tafonómica de una placa de quitón es el resultado de una combinación de factores biológicos, ecológicos y ambientales. Se concluye que los quitones constituyen buenos indicadores paleoecológicos y paleoambientales, ya que mantienen fidelidad ecológica respecto a las paleocomunidades de las cuales derivan, y también permiten evaluar los procesos post-mortem ocurridos hasta su descubrimiento.

CHILEAN MARINE MOLLUSCA OF NORTHERN PATAGONIA COLLECTED DURING THE CIMAR-10 FJORDS CRUISE Gayana
Cárdenas,Javiera; Aldea,Cristian; Valdovinos,Claudio.
The tip of the South American cone is one of the most interesting Subantarctic areas, both biogeographically and ecologically. Nonetheless, knowledge of the area's biodiversity, in particular that of the subtidal marine habitats, remains poor. Therefore, in 2004, a biodiversity research project was carried out as a part of the cruise Cimar-10 Fjords, organized and supported by the Chilean National Oceanographic Committee (CONA). The results of the subtidal marine mollusk surveys are presented herein. The samples were collected aboard the Agor 60 "Vidal Gormaz" in winter 2004. The study area covered the northern Chilean Patagonia from Seno de Relocanví (41°31'S) to Boca del Guafo (43°49'S), on the continental shelf from 22 to 353 m depth. The Mollusca were...

Chitons (Mollusca: Polyplacophora) procured by the CANCAP I-VII expeditions, 1976-86 Naturalis
Kaas, P..
The 327 specimens of chitons captured during six out of seven CANCAP Expeditions have been examined. They belong to 26 species, including two recently described ones: Ischnochiton (Stenosemus) substriatus Kaas & Van Belle, 1990 and Ischnochiton (Ischnochiton nicklesi Kaas & Van Belle, 1990. Callistochiton pachylasmae (Di Monterosato, 1878) has been found off the coast of Morocco.

Chitons (Mollusca: Polyplacophora) procured by the French Benthédi-expédition, 1977, and the Md 32-réunion-expédition, 1982, in the Southwestern Indian Ocean Naturalis
Kaas, P..
The late Eugène Leloup examined samples from five stations of the Benthédi-Expédition, 1977, in the North of the Mozambique Channel, containing four species of chitons, two of which proved to be new to science. The material here discussed, coming from eighteen Benthédistations, proved to contain fourteen species, among which the four previously reported by Leloup (1981), and two hitherto unknown, here described as Leptochiton (Leptochiton) gloriosus spec, nov. and Ischnochiton (Ischnochiton) crassus spec. nov. The Réunion material came from nine stations and contains five species of chitons, two of which are new, viz. Leptochiton (Leptochiton) kurnilatus spec. nov. and Ischnochiton (Stenosemus) vitreolus spec. nov.

First inventory of benthic mollusks associated with the reef ecosystems of Morro de São Paulo on Tinharé Island in northeastern Brazil Biota Neotropica
Lima,Silvio Felipe Barbosa; Lima,Bianca Vieira; Abreu,Evandro Cosmo; Oliveira,Geraldo Semer Pomponet; Lucena,Rudá Amorim; Mendonça,Luana Marina de Castro; Prata,Jéssica; Souza,J. Weverton S. de.
Abstract: The reef ecosystems of Morro de São Paulo are located in the Tinharé-Boipeba Environmental Preservation Area which was established in 1992 in the state of Bahia, Brazil. Despite this area has been created more than two decades ago, no study has provided knowledge on the invertebrate biodiversity associated with such reef ecosystems. The present investigation provides the first inventory of benthic mollusks associated with the reef ecosystems of Morro de São Paulo based on the collection of living specimens and fresh empty as well as some worn shells. Mollusks were sampled in January 2015 and August 2016 through intensive searches from the intertidal to shallow subtidal habitats of the reefs on three beaches of Morro de São Paulo. Taxonomic...

Lorentz Spengler's descriptions of chitons (Mollusca: Polyplacophora) Naturalis
Kaas, P.; Knudsen, J..
The present paper deals with an important Danish paper on the Polyplacophora, published in 1797 by Lorentz Spengler: Udförlig Beskrivelse over det mangeskallede Konkylie-Slaegt, af Linnaeus kaldet Chiton; med endeel nye Arter og Varieteter. -Skrivter af Naturhistorie-Selskabet, 4e Bind, Ie Hefte, VI: 62-103, Tab. VI (Kiöbenhavn). In order to make this historical paper accessible to students of the group, a translation (by Dr J. Knudsen, with the assistance of the late Mrs A. Volsoe) of the original 18th century Danish text into modern English is here presented. A considerable part of the material in the "Museo Spengleriano", on which Spengler based his descriptions, is still extant, being held now in the Zoological Museum, University of Copenhagen. The...

The Genus Lepidochitona Gray, 1821 (Mollusca: Polyplacophora) in the Northeastern Pacific Ocean (Oregonian and Californian Provinces) Naturalis
Eernisse, D.J..
The systematics of the northeastern Pacific Lepidochitona from the Californian and Oregonian Provinces (western continental United States) is presented and discussed. Three new species are described: L. caverna spec. nov. and L. berryana spec. nov. from California, and L. fernaldi spec. nov. from Washington and Oregon. These species are compared in most detail to the nominal species L. dentiens (Gould, 1846), L. hartwegii (Carpenter, 1855), L. thomasi (Pilsbry, 1898) and L. keepiana Berry, 1948.
