The Eggs and Larvre of Turritella Communis Lamarck and Aporrhais Pes-Pelicani (L.)
[ 499 ] The Eggs and Larvre of Turritella communis Lamarck and Aporrhais pes-pelicani (L.). By Marie V. Lebour, D.Se., Naturalist at the Plymouth Laboratory. With Plates 1-2. NOTHINGis known of the eggs and larvre of Turritella communis and, except for the young shells which have already metamorphosed, those of Aporrhais pes-pelicani are also unknown. The following descriptions are therefore new, both molluscs having been kept in plunger-jars until they laid their eggs. TURRITELLA COMMUNIS LAMARCK. (Plate 1.) Turritella communis is dredged alive in abundance in certain localities round Plymouth on muddy and sandy gravel, 15-30 fathoms or, rarely in over 40 fathoms (see Plymouth Marine Fauna, 1931, Marine Biological Association). Many were kept alive in plunger-jars, but, although they lived for a long time, feeding on detritus accumulating on the glass sides, . no eggs were obtained for several months. At last, in May, some eggs were deposited in one of the jars, and after that several lots were laid up to August. Occasionally detached egg capsules were found in the plank- ton. Ripe sperm and nearly ripe eggs were found in November and February in a few individuals. I am indebted to Miss M. Rothschild and Mr. ldris Jones for records of much ripe sperm and ripe eggs in April, and very few in September. Apparently April to July is the natural breeding season as after June most of the eggs were shed. Three egg-masses were found in a plunger-jar, 12.5.32. Each of these was a large cluster of capsules measuring from 6 to 10 mm. -
The First Geological Map of Patagonia
Revista de la Asociación Geológica Argentina 64 (1): 55 - 59 (2009) 55 THE FIRST GEOLOGICAL MAP OF PATAGONIA Eduardo O. ZAPPETTINI and José MENDÍA Servicio Geológico Minero Argentino (SEGEMAR) - Av. Julio A. Roca 651 (1322) Buenos Aires Emails: [email protected], [email protected] ABSTRACT This contribution analyses the first geological map of Patagonia drawn by Darwin around 1840, and colour-painted by Darwin himself. It had remained unpublished and only a small version in black and white had been printed before. The different units mapped by Darwin are analysed from a modern perspective, and his ability to show a synthesis of the complex geological structure of Patagonia is stressed. Keywords: Geological map, Patagonia, Patagonian Shingle, Darwin geologist. RESUMEN: El primer mapa geológico de la Patagonia. La presente contribución analiza el primer mapa geológico de la Patagonia reali- zado por Darwin cerca de 1840, pintado en colores por el mismo Darwin, que ha permanecido inédito y del que sólo se cono- cía una versión de tamaño reducido en blanco y negro. Se analizan las diferentes unidades mapeadas por Darwin desde una perspectiva actual, destacándose su habilidad para mostrar en esa síntesis la compleja estructura de la Patagonia. Palabras clave: Mapa geológico, Patagonia, Rodados Patagónicos, Darwin geólogo. DARWIN AND THE VOYAGE OF HMS BEAGLE At the time Charles Darwin set sail on board HMS Beagle on a journey that was to last two years and ended up lasting five, he was not more than an amateur naturalist that had quitted his medical courses and after that abandoned his in- tention of applying for a position in the Church of England, just to embrace the study of natural history. -
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. -

Seasearch Wales 2012 Summary Report report prepared by Kate Lock, South and West Wales coco----ordinatorordinator Liz MorMorris,ris, North Wales coco----ordinatorordinator Chris Wood, National coco----ordinatorordinator Seasearch Wales 2012 Seasearch is a volunteer marine habitat and species surveying scheme for recreational divers in Britain and Ireland. It is coordinated by the Marine Conservation Society. This report summarises the Seasearch activity in Wales in 2012. It includes summaries of the sites surveyed and identifies rare or unusual species and habitats encountered. These include a number of Welsh Biodiversity Action Plan habitats and species. It does not include all of the detailed data as this has been entered into the Marine Recorder database and supplied to Natural Resources Wales for use in its marine conservation activities. The data is also available on-line through the National Biodiversity Network. During 2012 we continued to focus on Biodiversity Action Plan species and habitats and on sites that had not been previously surveyed. Data from Wales in 2012 comprised 192 Observation Forms, 154 Survey Forms and 1 sea fan record. The total of 347 represents 19% of the data for the whole of Britain and Ireland. Seasearch in Wales is delivered by two Seasearch regional coordinators. Kate Lock coordinates the South and West Wales region which extends from the Severn estuary to Aberystwyth. Liz Morris coordinates the North Wales region which extends from Aberystwyth to the Dee. The two coordinators are assisted by a number of active Seasearch Tutors, Assistant Tutors and Dive Organisers. Overall guidance and support is provided by the National Seasearch Coordinator, Chris Wood. -

The want of a complete and consistent list of the principal subdivisions of the mollusks having been experienced for some time, and such a list being at length imperatively needed for the arrangement of the collections of the Smithsonian Institution, the present arrangement has been compiled for that purpose. It must be considered simply as a provisional list, embracing the results of the most recent and approved researches into the systematic relations and anatomy of those animals, but from which innova- tions and peculiar views, affecting materially the classification, have been excluded. -

American Fisheries Society Symposium 41:439–460, 2005 © 2005 by the American Fisheries Society Effects of Commercial Otter Trawling on Benthic Communities in the Southeastern Bering Sea ELOISE J. BROWN,1 BRUCE FINNEY, AND SUE HILLS Institute of Marine Science, University of Alaska Fairbanks, 245 O’Neill Building, Post Office Box 757220, Fairbanks, Alaska 99775, USA MICHAELA DOMMISSE Monash University, Department of Geography and Environmental Science, Post Office Box 11A, Clayton 3168, Australia Abstract. The effects of commercial bottom trawling for yellowfin sole Limanda aspera on benthic communities were investigated in a sandy habitat exposed to high wave and tidal disturbance at 20–30 m depth in the southeastern Bering Sea. We compared an area that has been closed to commercial trawling for 10 years with an adjacent area that is now open to commercial trawling. In addition, we examined the immediate effects of experimental trawling on benthic community structure in the area closed to trawling. The fished area was characterized by reduced macrofauna density, biomass, and richness relative to the closed (unfished) area, but diversity was not different. Interannual variability of macrofauna assemblages was high in the system, yet assemblages in the two areas were distinguished using multivariate analyses and dominant taxa. After 10 years, sessile taxa (e.g., Maldanidae polychaetes) were prevalent in the closed area, and mobile scavengers (e.g., Lysianassidae amphipods) were more common in the fished area. Immediate responses of macrofauna to experimental trawling were subtle (i.e., reduced richness, absence of rare taxa, and patchy changes in assemblage biomass), but no differences were detected relative to controls for density, diversity, or total biomass. -

This compilation forms the data base for a series of studies published, in press or in preparation (Buzas, £t_ al. , 1982; Koch and Sohl, in press). The Haustator bilira Assemblage Zone was proposed by Sohl (1977) and traced through Late Cretaceous rocks of the Atlantic and Gulf Coastal Plains from New Jersey to Texas (Owens, et_jil_., 1977; Sohl and Smith, 1980). The base of the zone occurs above the base of the foraminiferid Globotruncana gansseri subzone of Pessagno (1967) and includes all subsequent younger Cretaceous deposits on the Coastal Plains (Figure 2). -
