Étude Sur L'alimentation D'aeolidia Papi Llosa L
ÉTUDE SUR L'ALIMENTATION D'AEOLIDIA PAPI LLOSA L. par Jean-Claude Moreteau Station biologique de Roscoff et Laboratoire de Zoologie, Université Paris-Sud, Centre d'Orsay - 91405 Orsay Résumé Après une étude biologique d'Aeolidia papillosa en milieu naturel (herbier des environs de Roscoff), ce travail aborde l'adaptation alimentaire du Nudi- branche à ses proies (les Actiniaires). A partir de l'étude du cnidome des proies, on établit un coefficient de présence pour chaque type de cnidocyste dans chaque tissu. Une analyse qualitative et quantitative des fèces du prédateur permet de dégager certains faits. Les basitriches sont stockés dans les sacs cnidophores et sont aussi rejetés régulièrement. Tous les autres cnidocystes, à part les mastigophores microbasiques, sont rejetés très rapidement et sans subir de dégradation. Par contre, les mastigophores microbasiques sont rejetés plus tardivement et en grande partie dégradés. La quantité de chaque type de cnido- cyste dans les fèces confirme que le prédateur n'a pas la même appétence envers les différents tissus. Il existe une bonne relation entre le comportement prédateur du Nudibranche et son appétence envers les différents tissus de la proie. Introduction Les préférences alimentaires d'Aeolidia papillosa ont fait l'objet de nombreuses observations. Cela a permis de dresser la liste des proies du Nudibranche (Miller, 1961 ; Swennen, 1961 ; Waters, 1973 ; Edmunds et coll., 1974 pour ne citer que les travaux les plus récents). Corrélativement, des études ont porté sur le choix de la proie par ce Nudibranche (Stehouwer, 1952 ; Braams et Geelen, 1953 ; Waters, 1973 ; Edmunds et coll., 1974), ainsi que sur les réactions des Actiniaires vis-à-vis du prédateur (Robson, 1966 ; Waters, 1973 ; Edmunds et coll., 1976). -
R on Anew British Sea Anemone. by T
[ 880 ~ r On aNew British Sea Anemone. By T. A~ Stephenson, D.Se., Department of Zoology, University Oollege, London With 1 Figure in the Text. IT is a curious fact that the majority of the British anemones had been discovered by 1860, and that half of them, as listed at that date, had been established during a burst of energy on the part of Gosse and his collectingfriends. Gosseadded 28 speciesto the BritishFauna himself. It is still more surprising that since Gosse ceased work, no authentic new ones have been added, other than more or less offshore forms, with'the ex- ception of Sagartia luci()3,'and this species appears to have been imported from abroad. There is, however, an anemone which occurs on the Break- water and Pier at Plymouth, which has not yet been described. Dr. Allen tells me it has been on the Breakwater as long as he can remember, and to him I am indebted for the details of its habitat given further on. Whether it occurs elsewhere than in the Plymouth district and has been seen but mistaken for the young of Metridiurn dianthus, is as yet unknown. The anemone in question, which is the subject of this paper, is a small creature, bright orange or fawn in colour, and presenting at first sight some resemblance to. young specimens of certain colour-varieties of Metridium. When the two forms are observed carefully, however, and irnder heaJ:thy conditions, it becomes evident that they are perfectly distinct from each other; and a study of their anatomy bears out this fact. -
Seasearch Seasearch Wales 2012 Summary Report Summary Report
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 primary aim of this paper is to show tha~ among certain Actinians investigated, the species are sharply differentiated by their divers methods of reproduction; and to point out that the general question of species is one which is worthy of the attention of experimental biologists. Arguments supporting these contentions will be found in Section 7. I should like to make the following acknowledgments. I have received a grant, which has made the work described possible, from the Department of Scientific and Industrial Research. I have received interest and advice from Prof. Watson, and invaluable assistance (detailed below) from Mr. W. Edgar Evans. The whole cultural side of the work was carried out by my wife, who also provided Text-Figs. 2 and 3, and the sections from which they were drawn. I am very much indebted also to the Plymouth staff and to Miss M. Delap, of Valencia, and Mr. Ehnhirst, of Millport, for the collection of the large amount of material required. LIBRARY M.B.A. -

Sagartia Troglodytes (Anthozoa: Actiniaria) Consists of Two Species
Vol. 41: 21-28, 1987 MARINE ECOLOGY - PROGRESS SERIES Published November 25 Mar. Ecol. hog. Ser. Sagartia troglodytes (Anthozoa: Actiniaria) consists of two species P. W. Shaw, J. A. Beardmore, J. S. Ryland Marine, Environmental and Evolutionary Research Group, School of Biological Sciences, University College of Swansea, Swansea SA2 8PP. United Kingdom ABSTRACT: The sagartiid sea anemone Sagartia troglodytes (Price) has usually been considered to consist of 2 morphological varieties hked by intermediate forms (and therefore presumably by interbreeding). The techniques of starch gel electrophoresis and chromosome preparation, combined with an analysis of reproductive biology, were employed to investigate populations around the SW coasts of Britain to test this assumption. Var. decorata is extremely variable both morphologically and genetically with high levels of polymorphism and heterozygosity (P = 61 %, H, = 0.27). It reproduces exclusively by out-crossing, oviparous means producing maximal genotypic diversity and good gene flow between populations (Nei's Genetic Identity, 1 = 0.99). Var. ornata is less variable morphologically but genetically diverse (P = 62 %, H. = 0.47) due to 'fixed heterozygosity' at some locl, which is maintained by extensive clonal reproduction within populations producing relatively low inter-popula- tion identity (f = 0.86). Var. decorata has a chromosonle number of approximately 24 whereas var. ornata has approximately 48. On this basis it is proposed that var.decorata should retain the species name S. troglodytes (Price) and that var. ornata be restored to species status as Sagartia ornata (Holdsworth, in Gosse 1860). INTRODUCTION Riemann-Zurneck 1969, Schmidt 1972), although no detailed information of reproductive cycles is available. Sagartia troglodytes (Price) is a widespread, if not The present study was undertaken to provide infor- prolific, sea anemone. -
Mollusc World Magazine
IssueMolluscWorld 24 November 2010 Glorious sea slugs Our voice in mollusc conservation Comparing Ensis minor and Ensis siliqua THE CONCHOLOGICAL SOCIETY OF GREAT BRITAIN AND IRELAND From the Hon. President Peter has very kindly invited me to use his editorial slot to write a piece encouraging more members to play an active part in the Society. A few stalwarts already give very generously of their time and energy, and we are enormously grateful to them; but it would be good to spread the load and get more done. Some of you, I know, don’t have enough time - at least at the moment - and others can’t for other reasons; but if you do have time and energy, please don’t be put off by any reluctance to get involved, or any feeling that you don’t know enough. There are many ways in which you can take part – coming to meetings, and especially field meetings; sending in records; helping with the records databases and the website; writing for our publications; joining Council; and taking on one of the officers’ jobs. None of us know enough when we start; but there’s a lot of experience and knowledge in the Society, and fellow members are enormously helpful in sharing what they know. Apart from learning a lot, you will also make new friends, and have a lot of fun. The Society plays an important part in contributing to our knowledge of molluscs and to mollusc conservation, especially through the database on the National Biodiversity Network Gateway (www.nbn.org.uk); and is important also in building positive links between professional and amateur conchologists. -
Gangliogenesis in the Prosobranch Gastropod Ilyanassa Obsoleta By
Gangliogenesis in the Prosobranch Gastropod Ilyanassa obsoleta By: Miao-Fang Lin and Esther M. Leise Lin, M.-F. and Leise, E.M. (1996) Gangliogenesis in the Prosobranch Gastropod Ilyanassa obsoleta. Journal of Comparative Neurology 374(2):180-193. Made available courtesy of Wiley-Blackwell: The definitive version is available at http://www3.interscience.wiley.com ***Reprinted with permission. No further reproduction is authorized without written permission from Wiley-Blackwell. This version of the document is not the version of record. Figures and/or pictures may be missing from this format of the document.*** Abstract: We determined that the larval nervous system of Ilyanassa obsoleta contains paired cerebral, pleural, pedal, buccal, and intestinal ganglia and unpaired apical, osphradial, and visceral ganglia. We used a modified form of NADPH diaphorase histochemistry to compare the neuroanatomy of precompetent (including specimens 6, 8, and 12 days after hatching), competent, and metamorphosing larvae with postmetamorphic juveniles. This method highlighted ganglionic neuropils and allowed us to identify individual ganglia at various stages of development, thereby laying a foundation for concurrent histochemical studies. The first ganglia to form were the unpaired apical and osphradial ganglia and the paired cerebral and pedal ganglia. In larvae 6 days after hatching, the neuropil had already appeared in the apical and osphradial ganglia. Neuropil began to be apparent in the cerebral and pedal ganglia 2 days later. At that time, the pleural and buccal ganglia were identifiable and adjacent to the posterior edge of the cerebral ganglia. The ganglia of the visceral loop were concurrently recognizable, although the supraintestinal ganglion developed slightly earlier than the subintestinal and visceral ganglia.
