COMMISSIONED REPORT Summary Seagrass (Zostera) beds in Orkney Commissioned Report No. 765 Project No: 848 Contractors: Emma Jackson (The Marine Biological Association of the United Kingdom) and Malcolm Thomson (Sula Diving) Year of publication: 2014 Keywords Seagrass; Zostera marina; Orkney; predictive model; survey. Background Seagrasses (Zostera spp) are marine flowering plants that develop on sands and muds in sheltered intertidal and shallow subtidal areas. Seagrass beds are important marine habitats but are vulnerable to a range of human induced pressures. Their vulnerability and importance to habitat creation and ecological functioning is recognised in their inclusion on the recommended Priority Marine Features list for Scotland’s seas. Prior to this study, there were few confirmed records of Zostera in Orkney waters. This study combined a predictive modelling approach with boat-based surveys to enhance under- standing of seagrass distribution in Orkney and inform conservation management. -
Diversity of Norwegian Sea Slugs (Nudibranchia): New Species to Norwegian Coastal Waters and New Data on Distribution of Rare Species
Fauna norvegica 2013 Vol. 32: 45-52. ISSN: 1502-4873 Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species Jussi Evertsen1 and Torkild Bakken1 Evertsen J, Bakken T. 2013. Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species. Fauna norvegica 32: 45-52. A total of 5 nudibranch species are reported from the Norwegian coast for the first time (Doridoxa ingolfiana, Goniodoris castanea, Onchidoris sparsa, Eubranchus rupium and Proctonotus mucro- niferus). In addition 10 species that can be considered rare in Norwegian waters are presented with new information (Lophodoris danielsseni, Onchidoris depressa, Palio nothus, Tritonia griegi, Tritonia lineata, Hero formosa, Janolus cristatus, Cumanotus beaumonti, Berghia norvegica and Calma glau- coides), in some cases with considerable changes to their distribution. These new results present an update to our previous extensive investigation of the nudibranch fauna of the Norwegian coast from 2005, which now totals 87 species. An increase in several new species to the Norwegian fauna and new records of rare species, some with considerable updates, in relatively few years results mainly from sampling effort and contributions by specialists on samples from poorly sampled areas. doi: 10.5324/fn.v31i0.1576.

This study was carried out, through a total of 271 scuba dives, from 2017 to the beginning of 2020 in four sites located along the Ionian coasts of Sicily: Catania, Aci Trezza, Santa Maria La Scala and Santa Tecla. Through a photographic data collection, 95 taxa, representing 17.27% of all Mediterranean marine Heterobranchia, were reported. The order with the highest number of found species was that of Nudibranchia. Among the study areas, Catania, Santa Maria La Scala and Santa Tecla had not a remarkable difference in the number of species, while Aci Trezza had the lowest number of species. Moreover, among the 95 taxa, four species considered rare and six non-indigenous species have been recorded. Since the presence of a high diversity of sea slugs in a relatively small area, the central-eastern coast of Sicily could be considered a zone of high biodiversity for the marine Heterobranchia fauna.

Ringiculid Bubble Snails Recovered As the Sister Group to Sea Slugs
www.nature.com/scientificreports OPEN Ringiculid bubble snails recovered as the sister group to sea slugs (Nudipleura) Received: 13 May 2016 Yasunori Kano1, Bastian Brenzinger2,3, Alexander Nützel4, Nerida G. Wilson5 & Accepted: 08 July 2016 Michael Schrödl2,3 Published: 08 August 2016 Euthyneuran gastropods represent one of the most diverse lineages in Mollusca (with over 30,000 species), play significant ecological roles in aquatic and terrestrial environments and affect many aspects of human life. However, our understanding of their evolutionary relationships remains incomplete due to missing data for key phylogenetic lineages. The present study integrates such a neglected, ancient snail family Ringiculidae into a molecular systematics of Euthyneura for the first time, and is supplemented by the first microanatomical data. Surprisingly, both molecular and morphological features present compelling evidence for the common ancestry of ringiculid snails with the highly dissimilar Nudipleura—the most species-rich and well-known taxon of sea slugs (nudibranchs and pleurobranchoids). A new taxon name Ringipleura is proposed here for these long-lost sisters, as one of three major euthyneuran clades with late Palaeozoic origins, along with Acteonacea (Acteonoidea + Rissoelloidea) and Tectipleura (Euopisthobranchia + Panpulmonata). The early Euthyneura are suggested to be at least temporary burrowers with a characteristic ‘bubble’ shell, hypertrophied foot and headshield as exemplified by many extant subtaxa with an infaunal mode of life, while the expansion of the mantle might have triggered the explosive Mesozoic radiation of the clade into diverse ecological niches. The traditional gastropod subclass Euthyneura is a highly diverse clade of snails and slugs with at least 30,000 living species1,2. -
The Genital Systems of Trivia Arctica and Trivia Monacha (Prosobranchia, Mesogastropoda) and Tributyltin Induced Imposex1
Zoo1. Beitr. N. F. 34 (3): 349 - 374 (1992) (Institut für Spezielle Zoologie und Vergleichende Embryologie der Westfälischen Wilhelms-Universität Münster) The genital systems of Trivia arctica and Trivia monacha (Prosobranchia, Mesogastropoda) and tributyltin induced imposex1 EBERHARD STROBEN, CHRISTA BROlVlMEL, JORG OEHLMANN and PIO FIORONI Received June 17 , 1992 Summary The mesogastropod prosobranchs Trivia arctica and T. monacha collected along the coast of Brittany and Normandy between 1988 and 1992 exhibit imposex or pseudohermaphroditism (occurrence of male parts in addition to the female genital system) in response to tributyltin (TBT) pollution. Beside some normal females (stage 0) different imposex stages according to the classification of FIORONI et a1. (1991) (3 a, 3 band 4 for T. arctica and 3b and 4 for T. monacha) (Fig. 1) can be distinguished and are documented with scanning electron micrographs for the first time. Additional al terations of the genital tract e.g. excrescences on the vas deferens, a coiled oviduct, a bi- or trifurcated penis or several penes (2 - 5) are described. Neither TBT-induced sterilization nor sex change occur. TBT accumulation in soft parts shows sex-related differences. The VDS (vas deferens sequence) index, uncubed RPS (relative penis size) index and average female penis length of a population are dependent from TBT con centrations in ambient sea water and TBT body burden. A statistical study, based on an analysis of natural populations of T. arctica, T. monacha and Nucella lapillus allows a comparison of the specific TBT sensitivity of the three TBT bioindicators. N. lapillus exhibits a lower threshold for imposex development and a higher TBT sen sitivity, but both Trivia species proved to be suitable TBT bioindicators. -
Rocky Shore Snails As Material for Projects (With a Key for Their Identification)
Field Studies, 10, (2003) 601 - 634 ROCKY SHORE SNAILS AS MATERIAL FOR PROJECTS (WITH A KEY FOR THEIR IDENTIFICATION) J. H. CROTHERS Egypt Cottage, Fair Cross, Washford, Watchet, Somerset TA23 0LY ABSTRACT Rocky sea shores are amongst the best habitats in which to carry out biological field projects. In that habitat, marine snails (prosobranchs) offer the most opportunities for individual investigations, being easy to find, to identify, to count and to measure and beng sufficiently robust to survive the experience. A key is provided for the identification of the larger species and suggestions are made for investigations to exploit selected features of individual species. INTRODUCTION Rocky sea shores offer one of the best habitats for individual or group investigations. Not only is there de facto public access (once you have got there) but also the physical factors that dominate the environment - tides (inundation versus desiccation), waves, heat, cold, light, dark, salinity etc. - change significantly over a few metres in distance. As a bonus, most of the fauna and flora lives out on the open rock surface and patterns of distribution may be clearly visible to the naked eye. Finally, they are amongst the most ‘natural’ of habitats in the British Isles; unless there has been an oil spill, rocky sea shores are unlikely to have been greatly affected by covert human activity. Some 270 species of marine snail (Phylum Mollusca, Class Gastropoda; Sub-Class Prosobranchia) live in the seas around the British Isles (Graham, 1988) and their empty shells may be found on many beaches. Most of these species are small (less than 3 mm long) or live beneath the tidemarks. -
