Donacidae - Bivalvia)
Bolm. Zool., Univ. S. P aub 3:121-142, 1978 FUNCTIONAL ANATOMY OF DON AX HANLEY ANUS PHILIPPI 1847 (DONACIDAE - BIVALVIA) Walter Narchi Department o f Zoology University o f São Paulo, Brazil ABSTRACT Donax hanleyanus Philippi 1847 occurs throughout the southern half o f the Brazilian littoral. The main organ systems were studied in the living animal, particular attention being paid to the cilia ry feeding and cleasing mechanisms in the mantle cavity. The anatomy, functioning of the stomach and the ciliary sorting mechanisms are described. The stomach unlike that of almost all species of Donax and like the majority of the Tellinacea belongs to type V, as defined by Purchon, and could be regarded as advanced for the Donacidae. A general comparison has been made between the known species of Donax and some features of Iphigenia brasiliensis Lamarck 1818, also a donacid. INTRODUCTION Very little is known of donacid bivalves from the Brazilian littoral. Except for the publications of Narchi (1972; 1974) on Iphigenia brasiliensis and some ecological and adaptative features on Donax hanleyanus, all references to them are brief descrip tions of the shell and cheklists drawn up from systematic surveys. Beach clams of the genus Donax inhabit intertidal sandy shores in most parts of the world. Donax hanleyanus Philippi 1847 is one of four species occuring through out the Brazilian littoral. Its known range includes Espirito Santo State and the sou thern Atlantic shoreline down to Uruguay (Rios, 1975). According to Penchaszadeh & Olivier (1975) the species occur in the littoral of Argentina. 122 Walter Narchi The species is fairly common in São Paulo, Parana and Santa Catarina States whe re it is used as food by the coastal population (Goffeijé, 1950), and is known as “na- nini” It is known by the name “beguara” (Ihering, 1897) in the Iguape region, but not in S. -
Hiller & Lessios 2017
www.nature.com/scientificreports OPEN Phylogeography of Petrolisthes armatus, an invasive species with low dispersal ability Received: 20 February 2017 Alexandra Hiller & Harilaos A. Lessios Accepted: 27 April 2017 Theoretically, species with high population structure are likely to expand their range, because marginal Published: xx xx xxxx populations are free to adapt to local conditions; however, meta-analyses have found a negative relation between structure and invasiveness. The crab Petrolisthes armatus has a wide native range, which has expanded in the last three decades. We sequenced 1718 bp of mitochondrial DNA from native and recently established populations to determine the population structure of the former and the origin of the latter. There was phylogenetic separation between Atlantic and eastern Pacific populations, and between east and west Atlantic ones. Haplotypes on the coast of Florida and newly established populations in Georgia and South Carolina belong to a different clade from those from Yucatán to Brazil, though a few haplotypes are shared. In the Pacific, populations from Colombia and Ecuador are highly divergent from those from Panamá and the Sea of Cortez. In general, populations were separated hundreds to million years ago with little subsequent gene flow. High genetic diversity in the newly established populations shows that they were founded by many individuals. Range expansion appears to have been limited by low dispersal rather than lack of ability of marginal populations to adapt to extreme conditions. The population-genetic constitution of marine invasive species in their native range is increasingly being stud- ied in efforts to determine the source of invasions into new areas (reviews in refs 1–5). -

Genetic Distances of Three Venerid Species Identified by PCR Analysis
Korean J. Malacol. 31(4): 257-262 2015 http://dx.doi.org/10.9710/kjm.2015.31.4.257 Genetic distances of three venerid species identified by PCR analysis Jun-Hyub Jeon and Jong-Man Yoon Department of Aquatic Life Medicine, College of Ocean Science and Technology, Kunsan National University, Gunsan 54150, Korea ABSTRACT The seven selected primers BION-13, BION-29, BION-61, BION-64, BION-68, BION-72 and BION-80 generated the total number of loci, average number of loci per lane and specific loci in Meretrix lusoria (ML), Saxidomus purpuratus (SP) and Cyclina sinensis (CS) species. Here, the complexity of the banding patterns varied dramatically between the primers from the three venerid clam species. The higher fragment sizes (> 1,000 bp) are much more observed in the SP species. The primer BION-68 generated 21 unique loci to each species, which were ascertaining each species, approximately 150 bp, 300 bp and 450 bp, in the ML species. Remarkably, the primer BION-80 detected 7 shared loci by the three clam species, major and/or minor fragments of sizes 500 bp, which were matching in all samples. As regards average bandsharing value (BS) results, individuals from CS clam species (0.754) exhibited higher bandsharing values than did individuals from SP clam species (0.607) (P < 0.05). In this study, the dendrogram obtained by the seven oligonucleotides primers indicates three genetic clusters: cluster 1 (LUSORIA01-LUSORIA07), cluster 2 (PURPURATUS08-PURPURATUS14), cluster 3 (SINENSIS15- SINENSIS21). Among the twenty one venerid clams, the shortest genetic distance that displayed significant molecular differences was between individuals 18 and 20 from the CS species (genetic distance = 0.071), while the longest genetic distance among the twenty-one individuals that displayed significant molecular differences was between individuals LUSORIA no. -
Early Ontogeny of Jurassic Bakevelliids and Their Bearing on Bivalve Evolution
Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution NIKOLAUS MALCHUS Malchus, N. 2004. Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution. Acta Palaeontologica Polonica 49 (1): 85–110. Larval and earliest postlarval shells of Jurassic Bakevelliidae are described for the first time and some complementary data are given concerning larval shells of oysters and pinnids. Two new larval shell characters, a posterodorsal outlet and shell septum are described. The outlet is homologous to the posterodorsal notch of oysters and posterodorsal ridge of arcoids. It probably reflects the presence of the soft anatomical character post−anal tuft, which, among Pteriomorphia, was only known from oysters. A shell septum was so far only known from Cassianellidae, Lithiotidae, and the bakevelliid Kobayashites. A review of early ontogenetic shell characters strongly suggests a basal dichotomy within the Pterio− morphia separating taxa with opisthogyrate larval shells, such as most (or all?) Praecardioida, Pinnoida, Pterioida (Bakevelliidae, Cassianellidae, all living Pterioidea), and Ostreoida from all other groups. The Pinnidae appear to be closely related to the Pterioida, and the Bakevelliidae belong to the stem line of the Cassianellidae, Lithiotidae, Pterioidea, and Ostreoidea. The latter two superfamilies comprise a well constrained clade. These interpretations are con− sistent with recent phylogenetic hypotheses based on palaeontological and genetic (18S and 28S mtDNA) data. A more detailed phylogeny is hampered by the fact that many larval shell characters are rather ancient plesiomorphies. Key words: Bivalvia, Pteriomorphia, Bakevelliidae, larval shell, ontogeny, phylogeny.

BERGMANS Instituut voor Taxonomische Zoologie (Zoologisch Museum) Plantage Middenlaan 53, Amsterdam The Netherlands SUMMARY Taxonomy and distribution of 14 Recent Australian species of the family Nuculidae Gray, 1824 are described and discussed. Available data on biology and ecology are added. Illustrations and distribution maps of all species are given. The genera Pronucula Hedley, 1902, and Deminucula Iredale, 1931, are considered synonyms of Nucula Lamarck, 1799. Rumptunucula is proposed as a new genus for Pronucula vincentiana Cotton and Godfrey, 1938. Lectotypes are selected for Nucula pusilla Angas, 1877, Nucula micans Angas, 1878, Nucula torresi Smith, 1885, Nucula dilecta Smith, 1891, Nucula hedfeyi Pritchard and Gatliff, 1904, Deminucula praetenta Iredale, 1924, Pronucufa mayi Iredale, 1930, and Pronucula saltator Iredale, 1939. Nucula micans Angas, Nucula hedleyi Pritchard and Gatliff, and Pronucula concentrica Cotton, 1930 are considered synonyms of Nucula pusilla Angas. Pronucula voorwindei Bergmans, 1969 is synonymized with Nucula torresi Smith. Nucula diaphana Prashad, 1932 and Pronucula flindersi Cotton, 1930 are ranked as subspecies of Nucula dilecta Smith. -
Reconnaître Les Principaux Bivalves Fouisseurs Ou Foreurs Au Moyen De Leurs Siphons
Reconnaître les principaux bivalves fouisseurs ou foreurs au moyen de leurs siphons. 56 espèces Clé de détermination des 20 taxons les plus gros Yves MÜLLER Yves Müller Mai 2016 Reconnaître les principaux bivalves fouisseurs ou foreurs au moyen de leurs siphons. Dans la quasi-totalité des ouvrages traitant des mollusques lamellibranches (ou mollusques bivalves), ce sont les coquilles qui sont décrites (la conchyologie) avec principalement la description des charnières pour la classification. Pour les parties molles (la malacologie) ce sont les branchies qui sont utilisées. Ce qui n’est pas très accessible au plongeur même photographe ! Selon Martoja (1995) 75 % des espèces de bivalves vivent dans les fonds meubles. Certaines espèces trahissent leur présence par leurs siphons qui affleurent à la surface du sédiment, mais il est difficile, au cours d’une plongée, d’identifier les bivalves enfouis dans le sédiment. D’autres espèces de bivalves vivent dans des substrats durs (bois, roche). Ils forent alors une loge dans ce substrat et en général seuls les siphons sont visibles. Le même problème se pose, à quelle espèce appartiennent les siphons ? Selon Bouchet et al. (1978 :92): « Les siphons constituent un moyen de détermination des bivalves aussi fiable que la coquille et la charnière ». Des auteurs anciens comme Deshayes (1844-1848), Forbes et Hanley (1850-1853), Jeffreys (1863, 1865) et Meyer & Möbius (1872) et quelques autres plus récents comme Owen (1953 ; 1959), Purchon (1955a, b), Holme (1959) et Amouroux (1980) ont décrit les siphons de plusieurs espèces. La plupart des espèces de bivalves mesurent entre un et plusieurs centimètres mais les siphons sont pour la plupart courts ou très fins et rétractiles au moindre danger, donc difficilement observables en plongée. -
Marine Invertebrate Diversity in Aristotle's Zoology

Moreover he works 25 centuries ago, and set it against current knowledge. The created the science of biology and the philosophy of analysis of information derived from a thorough study of his biology, while his animal studies profoundly infl uenced zoological writings revealed 866 records related to animals cur- rently classifi ed as marine invertebrates. These records corre- the origins of modern biology (Lennox, 2001a). His sponded to 94 different animal names or descriptive phrases which biological writings, constituting over 25% of the surviv- were assigned to 85 current marine invertebrate taxa, mostly ing Aristotelian corpus, have happily been the subject (58%) at the species level. A detailed, annotated catalogue of all of an increasing amount of attention lately, since both marine anhaima (a = without, haima = blood) appearing in Ar- philosophers and biologists believe that they might help istotle’s zoological works was constructed and several older in the understanding of other important issues of his confusions were clarifi ed. -

The Earliest Bioturbators As Ecosystem Engineers
Downloaded from http://sp.lyellcollection.org/ by guest on September 27, 2021 Engineering the Cambrian explosion: the earliest bioturbators as ecosystem engineers LIAM G. HERRINGSHAW1,2*, RICHARD H. T. CALLOW1,3 & DUNCAN MCILROY1 1Department of Earth Sciences, Memorial University of Newfoundland, Prince Philip Drive, St John’s, NL, A1B 3X5, Canada 2Geology, School of Environmental Sciences, University of Hull, Cottingham Road, Hull HU6 7RX, UK 3Statoil ASA, Stavanger 4035, Norway *Correspondence: [email protected] Abstract: By applying modern biological criteria to trace fossil types and assessing burrow mor- phology, complexity, depth, potential burrow function and the likelihood of bioirrigation, we assign ecosystem engineering impact (EEI) values to the key ichnotaxa in the lowermost Cambrian (Fortunian). Surface traces such as Monomorphichnus have minimal impact on sediment properties and have very low EEI values; quasi-infaunal traces of organisms that were surficial modifiers or biodiffusors, such as Planolites, have moderate EEI values; and deeper infaunal, gallery biodiffu- sive or upward-conveying/downward-conveying traces, such as Teichichnus and Gyrolithes, have the highest EEI values. The key Cambrian ichnotaxon Treptichnus pedum has a moderate to high EEI value, depending on its functional interpretation. Most of the major functional groups of mod- ern bioturbators are found to have evolved during the earliest Cambrian, including burrow types that are highly likely to have been bioirrigated. In fine-grained (or microbially bound) sedimentary environments, trace-makers of bioirrigated burrows would have had a particularly significant impact, generating advective fluid flow within the sediment for the first time, in marked contrast with the otherwise diffusive porewater systems of the Proterozoic.
