    Marine Biodiversity https://doi.org/10.1007/s12526-018-0861-1 ORIGINAL PAPER Errina argentina sp. nov., a new stylasterid (Hydrozoa: Stylasteridae) from Mar del Plata submarine canyon (Southwest Atlantic) M. C. Bernal1 & S. D. Cairns2 & P. E. Penchaszadeh1 & D. Lauretta1 Received: 2 November 2017 /Revised: 20 February 2018 /Accepted: 21 February 2018 # Senckenberg Gesellschaft für Naturforschung and Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract Errina is a cosmopolitan genus of arborescent stylasterids that includes, discounting Errina cyclopora incertae sedis, 26 recent species and one extinct species. So far, only one species has been described from the Southwest Atlantic (SWA) off Argentina, Errina antarctica. Here, we describe a new species from that region, Errina argentina, collected in the Mar del Plata submarine canyon at 1398m depth. The new species is most similar to Errina kerguelensis in general growth form, arrangement of pores, and coenosteal texture, but differs in coenosteal strip width, gastrostyle and gastropore tube morphology, ampullae position, and the presence of numerous flush dactylopores. It differs from E. antarctica in coenosteum color, gastropore and dactylopore spine size, and shape of flush dactylopores. This record provides an extension of the present known distribution of the genus Errina in the SWA off Argentina. Keywords Argentina . Biodiversity . Deep sea .

  • ABSTRACT Title of Dissertation: PATTERNS IN
    ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range.

  • 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.
