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.

A Blind Abyssal Corambidae (Mollusca, Nudibranchia) from the Norwegian Sea, with a Reevaluation of the Systematics of the Family
A BLIND ABYSSAL CORAMBIDAE (MOLLUSCA, NUDIBRANCHIA) FROM THE NORWEGIAN SEA, WITH A REEVALUATION OF THE SYSTEMATICS OF THE FAMILY ÁNGEL VALDÉS & PHILIPPE BOUCHET VALDÉS, ÁNGEL & PHILIPPE BOUCHET 1998 03 13. A blind abyssal Corambidae (Mollusca, Nudibranchia) SARSIA from the Norwegian Sea, with a reevaluation of the systematics of the family. – Sarsia 83:15-20. Bergen. ISSN 0036-4827. Echinocorambe brattegardi gen. et sp. nov. is described based on five eyeless specimens collected between 2538 and 3016 m depth in the Norwegian Sea. This new monotypic genus differs from other confamilial taxa in having the dorsum covered with long papillae and a radula formula n.3.1.3.n. The posterior notch in the notum and gill morphology, which have traditionally been used as generic characters in the family Corambidae, are considered to have little or no taxonomical value above species level. Instead of the currently described 11 nominal genera, we recognize as valid only Corambe and Loy, to which is now added Echinocorambe. Loy differs from Corambe in the asym- metrical lobes of the posterior notal notch and the presence of spicules in the notum. All other nominal genera are objective or subjective synonyms of these two.

Si bien la tendencia general de las capturas de abulón indica una disminución de las dos principales especies que la conforman (Haliotis fulgens y H corrugata), a partir de su máximo histórico en 1950, esta tendencia no ha sido uniforme ni entre especies ni entre las regiones de donde se extrae. -

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. -
1 Metagenetic Analysis of 2018 and 2019 Plankton Samples from Prince
Metagenetic Analysis of 2018 and 2019 Plankton Samples from Prince William Sound, Alaska. Report to Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC) From Molecular Ecology Laboratory Moss Landing Marine Laboratory Dr. Jonathan Geller Melinda Wheelock Martin Guo Any opinions expressed in this PWSRCAC-commissioned report are not necessarily those of PWSRCAC. April 13, 2020 ABSTRACT This report describes the methods and findings of the metagenetic analysis of plankton samples from the waters of Prince William Sound (PWS), Alaska, taken in May of 2018 and 2019. The study was done to identify zooplankton, in particular the larvae of benthic non-indigenous species (NIS). Plankton samples, collected by the Prince William Sound Science Center (PWSSC), were analyzed by the Molecular Ecology Laboratory at the Moss Landing Marine Laboratories. The samples were taken from five stations in Port Valdez and nearby in PWS. DNA was extracted from bulk plankton and a portion of the mitochondrial Cytochrome c oxidase subunit 1 gene (the most commonly used DNA barcode for animals) was amplified by polymerase chain reaction (PCR). Products of PCR were sequenced using Illumina reagents and MiSeq instrument. In 2018, 257 operational taxonomic units (OTU; an approximation of biological species) were found and 60 were identified to species. In 2019, 523 OTU were found and 126 were identified to species. Most OTU had no reference sequence and therefore could not be identified. Most identified species were crustaceans and mollusks, and none were non-native. Certain species typical of fouling communities, such as Porifera (sponges) and Bryozoa (moss animals) were scarce. Larvae of many species in these phyla are poorly dispersing, such that they will be found in abundance only in close proximity to adult populations. -

Frank The opisthobranch molluscs of Oregon have been little studied, and little is known about the biology of many species. The present study consisted of field and laboratory observations of Cape Arago opistho- branchs. Forty-six species were found, extending the range of six north- ward and two southward. New food records are presented for nine species; an additional 20 species were observed feeding on previously recorded prey. Development data are given for 21 species. Twenty produce plank- totrophic larvae, and Doto amyra produces lecithotrophic larvae, the first such example known from Eastern Pacific opisthobranchs. Hallaxa chani appears to be the first eudoridacean nudibranch known to have a subannual life cycle. Development, life cycles, food and competition, iv ranges, and the ecological role of nudibranchs are discussed. Nudi- branchs appear to significantly affect the diversity of the Cape Arago encrusting community. -
