I am guessing that unless you have children under the age of 7 it is unlikely. “Octonauts” is a well-made animation about a random collection of creatures (undersea adventurers) who live in an ‘octopod’ and travel the worlds’ oceans with a mission “to explore, rescue and protect”. I have to admit to enjoying it and I also think it is a wonderful introduction to the natural marine environment. Through a series of episodes viewers are introduced to a variety of marine animals and habitats from the vampire squid that lives in the midnight zone to a male sea horse about to give birth on a coral reef. So what is the relevance of the “Octonauts” to Porcupine? Watching this programme and listening to my two young sons talk about the marine environment with interest and enthusiasm has prompted me to think about how we connect, excite and educate people of all generations about our natural environment. The aims of Porcupine are: • To promote a wider understanding of the biology, ecology and distribution of marine organisms; • To stimulate interest in marine biodiversity, especially from young people; • To encourage interaction and exchange of information between those with interests in different aspects of marine biology, amateur and professional alike. So my question to you is “how well is Porcupine doing in working towards its’ aims?” If your answer is “ok” or “I don’t know” then I suggest we aren’t doing that well and we should ask ourselves “what do we need to do better?” or “what else should we be doing?” This issue certainly demonstrates how active Porcupine is as a Society with field trip reports from our 2012 trips to Guernsey and north Cornwall, further papers from the 2012 Porcupine Conference and notice of the Bioblitz in Strangford Lough in 2013. We have a wonderful diversity of articles from website reviews, short notes and sightings as well as papers on sea defences to crawfish so thank you to all contributors. What we are missing are contributions from students and graduates and this is an area where I think Porcupine “could do better”. I wonder if our connection to a younger generation of keen and interested amateur and professional marine people needs some work? This is something all of us can take some responsibility for so please do talk about Porcupine and spread the word about what we are - an informal and friendly society interested in marine natural history and recording.

República Saharaui, 2, 11519 Puerto Real, Cádiz, Spain. * Corresponding author - e-mail address: [email protected] ABSTRACT The study of hermit crabs from Alboran Sea has allowed recognition of two different morphological forms under what had been understood as Pagurus forbesii. Based on morphological observations with various species of Pagurus, and molecular studies, a new species is defined and described as P. pseudosculptimanus. An overview on species of Pagurus from the eastern Atlantic and Mediterranean Sea is provided. Key words: Pagurus, new species, Mediterranean, eastern Atlantic. 1 Introduction More than 170 species from around the world are currently assigned to the genus Pagurus Fabricius, 1775 (Lemaitre and Cruz Castaño 2004; Mantelatto et al. 2009; McLaughlin 2003, McLaughlin et al. 2010). This genus is complex because of there is high morphological variability and similarity among some species, and has been divided in groups (e.g. Lemaitre and Cruz Castaño 2004 for eastern Pacific species; Ingle, 1985, for European species) with difficulty (Ayón-Parente and Hendrickx 2012). This difficulty has lead to taxonomic problems, although molecular techniques have been recently used to elucidate some species (Mantelatto et al. 2009; Da Silva et al. 2011). Thirteen species are present in eastern Atlantic (European and the adjacent African waters) (Ingle 1993; Udekem d'Acoz 1999; Froglia, 2010, MarBEL Data System - Türkay 2012, García Raso et al., in press) but only nine of these (the first ones mentioned below) have been cited in the Mediterranean Sea, all of them are present in the study area (Alboran Sea, southern Spain).

Univ. of Barcclona. Avgda. Diagonal, 645. 08028 Barcelona. Spain. Abstract : The ascidians from a locality on the Spanish NE coast were sampled from November 1984 until January 1986, with the aim of studying their biological cycles. Only the results conceming the co­ lonial species will be presented here. The samplings were performed twice a month, and the relative abundance, reproductivc statc and presence of resistance forms of the compound ascidian species were evaluated. Many species feature seasonal variations in abundance and even disappear from the samples in the unfavourable season. The reproductive periods are always restricted to a certain part of the year and they are strongly correlated with the biogeographical distribution of the species. The tempe rature ap­ pears as the main factor controlling ascidian reproduction. Notes are made on the significance of the resistance forms in the families Polyclinidae and Didemnidae. Résumé: Les ascidics présentes dans les fonds rocheux d'une localité de la côte NE espagnole ont été étudiées depuis novembrc 1984 jusqu'à janvier 1986, dans Ic but de préciser leurs cycles biologiques. Dans ce travail, seuls les résultats correspondant à des espèces coloniales seront présentés. L'abondance relative, les périodes de reproduction sexuée et la présence de formes de résistance ont été évaluées deux fois par mois pendant l'étude. Beaucoup d'espèces montrcnt des variations saisonnières d'abondance, et quelques-unes même dis­ paraissent pendant la saison défavorable.

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.

It has a relatively short-lived larval stage, spending only limited time in the water column before settling on a desirable substrate. Early detection of this species is an important step in both the prevention of its spread and of successful eradication. Here we report the development of a qPCR based assay, targeted to a region of the mitochondrial cytochrome oxidase I gene, using TaqMan® MGB, for the early identification of S.

Ruiz Legacy Program Abstract: SSpecies introductions have increased dramatically in number, rate, and magnitude of impact in recent decades. In marine systems, invertebrates are the largest and most diverse component of coastal invasions throughout the world. Ascidians are conspicuous and well-studied members of this group, however, much of what is known about their invasion history is limited to particular species or locations. Here, we provide a large-scale assessment of invasions, using an extensive literature review and standardized field surveys, to characterize the invasion dynamics of non-native ascidians in the continental United States and Alaska.

Biodiversity Data Journal 4: e9273. https://doi.org/10.3897/BDJ.4.e9273 Abstract Background The checklist of the ascidian fauna (Tunicata: Ascidiacea) of Greece was compiled within the framework of the Greek Taxon Information System (GTIS), an application of the LifeWatchGreece Research Infrastructure (ESFRI) aiming to produce a complete checklist of species recorded from Greece. This checklist was constructed by updating an existing one with the inclusion of recently published records. All the reported species from Greek waters were taxonomically revised and cross-checked with the Ascidiacea World Database. New information The updated checklist of the class Ascidiacea of Greece comprises 75 species, classified in 33 genera, 12 families, and 3 orders. In total, 8 species have been added to the previous species list (4 Aplousobranchia, 2 Phlebobranchia, and 2 Stolidobranchia). Aplousobranchia was the most speciose order, followed by Stolidobranchia. Most species belonged to the families Didemnidae, Polyclinidae, Pyuridae, Ascidiidae, and Styelidae; these 4 families comprise 76% of the Greek ascidian species richness. The present effort revealed the limited taxonomic research effort devoted to the ascidian fauna of Greece, © Antoniadou C et al.
