Luciana Segura Andrade Universidade Federal do Triângulo Mineiro Natal, 2017 AGRADECIMENTOS Aos meus pais por acreditarem e apoiarem nesta caminhada acadêmica e me alimentarem mesmo comprometendo o orçamento da família. Aos professores Fúlvio Freire e Sérgio Lima (Prof. Xérxis) pela confiança, desempenho na orientação acadêmica e pela amizade. Ao meu amor Valéria Vale por acreditar, por vezes mais do que eu, na minha capacidade de continuar nesta empreitada e por não me abandonar nesta vida de muito trabalho e pouco dinheiro. À galera do Laboratório de Fauna Aquática pelo “conversadeiro de m...” diário, pelo apoio em laboratório e em campo. Em especial, a tia Anastacia (Roney), Walmir (Waldir), Lucianus marmoratus (Luciano), Jebis (Mateus Germano), Telton e Cadu Guedes (Carlos Eduardo, famoso Cadu) por arriscarem suas vidas, adquirirem dermatites incuráveis, viajando e coletando por esse Nordeste “velho de guerra”. Aos demais integrantes do Laboratório de Fauna Aquática, Espirito Inquieto (Matheus Arthur), Veiuda (Thaís), Demônio Daltônico (Bruna), Dr. Márcio, Carol Tupan (Carol Puppin), Carol Alimentos (Ana Carolina Xavier), Boy Ni Ni (Nielson), Flávia Peter Pan (Flávia Petean), Silvia Yasmin, Luquinhas, Boquinha de Hypostomus (Nathalia) e Aninha, por tornar o laboratório um ambiente alegre e descontraído, muitas vezes até de mais. À alguns colegas da pós-graduação e do laboratório que me ensinaram o que é uma atitude não profissional e o verdadeiro significado de ser otário. Obrigado por me ensinar não ser como vocês. Não quero citar nomes... rsrsrsrs... Às personalidades singulares “Índio Janduís”, “Minha mãe é uma pilantrinha” e ao Guia, autor das estórias de “Jú Cascata” e “Arara e Ipê” por propiciarem momentos de raiva e descontração durante nossas viagens de Kombi. À Empresa “PC Rent a Car” por fornecer uma Kombi confortável, arrejada, com sistema de direção remoto (o volante até sai), freios ABS e pintura temática (adesivagem tosca). Na verdade, aqui não é realmente um agradecimento, é puro sarcasmo. Ao Bar do Thomas e Bar do Pedrão por fornecer cerveja, às vezes gelada, kits (cachaça 51, Pepsi e limão) e um lugar “confortável” para promover discussões enriquecedoras sobre ecologia e biologia, arriação e alteração com direto a briga de bar e tudo mais. Em especial, à “Galega do Thomas” por transbordar toda sua doce ignorância ao servir nossas mesas. Aos “cara”, Kavera (Igor), Sérgio (Sérgio), Pedrinho (Pedro), Beiço (Gabriel) e Robson (in memoriam), por estarem sempre por perto pra beber e falar sobre assuntos aleatórios da vida. Em especial, à Sergeta (Sérgio) pelo empenho no serviço de tradução. Aos colegas de graduação que nunca pederam os laços afetivos, agradeço o carinho e atenção em mandar mensagem no WhatsApp, mesmo eu demorando semanas para responder. Ao pior cachorro do mundo, Loki, e a melhor cadela do mundo, Mel, por zelarem pela segurança do seu dono e da casa nas madrugadas que seu dono pegava no sono escrevendo e a casa “dormia” de portas abertas. Aos crustáceos que habitam meu aquário, Eriphia gonagra, Clibanarius sclopetarius, Clibanarius antillensis, Calcinus tibicen, Alpheus buckupi, Hepatus gronovii e Palaemon spp., por segurar minha atenção por horas e ver o quão interessante é o mundo dos crustáceos. Ao álcool, às vezes o da bancada serve, por procipiar o “desestresse”. À cafeína e taurina por tentar me manter acordado nas “madrugas” de escrita de artigo e ‘deadlines’. À Deus por promover a estocasticidade durante minha vida. OBRIGADO A TODOS!!! SUMÁRIO 1.

The new genus Necora is split off from the Portunid genus Liocarcinus Stimpson, 1871. A single species, Cancer puber L., 1767, is assigned to it. As the identity of Cancer puber L. is not certain (the original description fits Cancer corrugatus Pennant better) and as no type material is known to exist, a neotype specimen is selected so as to enable the specific name puber to be used for the species to which it has been applied for more than 150 years.

CONTENTS Introduction 1 Necora new genus 3 Necora puber (L., 1767) 8 References 12 INTRODUCTION The small European swimming crabs, which before 1950 were generally known to European authors as Portunus, have a rather complicated tax- onomic and nomenclatural history. The very early authors (e.g., Linnaeus, 1767; Pennant, 1777; Herbst, 1782-1804) placed them in the genus Cancer, which then included all crabs.

  • Occurrence of the Grey Swimming Crab Polybius Vernalis (Risso, 1827) on Rathiln Island, Northern Ireland: Northernmost Record So Far (Crustacea, Decapoda, Brachyura)
    DeStrandvlo3l(3-4) 230129 78 Occurrence of the grey swimming crab Polybius vernalis (Risso, 1827) on Rathiln Island, Northern Ireland: northernmost record so far (Crustacea, Decapoda, Brachyura) Cédric d'Udekem d'Acoz In Northwest Europe, the grey swimming crab Polybius vernalis (Risso, 1827) has long been confused with its close relatives P. holsatus (Fabricius, 1798) and P. marmoreus (Leach, 1814) (d'Udekem d'Acoz & Rappé, 1991; Ingle & Clark, 1998, as Liocarcinus spp.). It is not yet known how far north its distribution reaches, but its northernmost published record was from Clew Bay, Clare Island, west coast of Ireland, 53°47.4'N 009o51.6'W (McCarthy et al., 2005), and on the East coast of the British Isles, it was recorded as far north as River Orwell, 51058.64'N 001o16.50'E (Ashelby, 2006). A more northern record is reported here: a dead female missing its chelipeds, carapace size 25 x 31 mm, washed ashore at Rathlin Island, Church Bay, Northern Ireland, 55017'I8"N 006oir25"W,20.vii.2011 (fig. 1).

  • Why Protect Decapod Crustaceans Used As Models in Biomedical Research and in Ecotoxicology? Ethical and Legislative Considerations
    animals Article Why Protect Decapod Crustaceans Used as Models in Biomedical Research and in Ecotoxicology? Ethical and Legislative Considerations Annamaria Passantino 1,* , Robert William Elwood 2 and Paolo Coluccio 3 1 Department of Veterinary Sciences, University of Messina-Polo Universitario Annunziata, 98168 Messina, Italy 2 School of Biological Sciences, Queen’s University, Belfast BT9 5DL, Northern Ireland, UK; [email protected] 3 Department of Neurosciences, Psychology, Drug Research and Child Health (NEUROFARBA), University of Florence, Viale Pieraccini 6, 50139 Firenze, Italy; paolo.coluccio@unifi.it * Correspondence: [email protected] Simple Summary: Current European legislation that protects animals used for scientific purposes excludes decapod crustaceans (for example, lobster, crab and crayfish) on the grounds that they are non-sentient and, therefore, incapable of suffering. However, recent work suggests that this view requires substantial revision. Our current understanding of the nervous systems and behavior of decapods suggests an urgent need to amend and update all relevant legislation. This paper examines recent experiments that suggest sentience and how that work has changed current opinion. It reflects on the use of decapods as models in biomedical research and in ecotoxicology, and it recommends that these animals should be included in the European protection legislation. Abstract: Decapod crustaceans are widely used as experimental models, due to their biology, their sensitivity to pollutants and/or their convenience of collection and use. Decapods have been Citation: Passantino, A.; Elwood, viewed as being non-sentient, and are not covered by current legislation from the European Par- R.W.; Coluccio, P. Why Protect liament. However, recent studies suggest it is likely that they experience pain and may have the Decapod Crustaceans Used as capacity to suffer.

  • Survival of Decapod Crustaceans Discarded in the Nephrops Fishery

Bergmann and P. G. Moore Bergmann, M. and Moore, P. G. 2001. Survival of decapod crustaceans discarded in the Nephrops fishery of the Clyde Sea area, Scotland. – ICES Journal of Marine Science, 58: 163–171. The Clyde Sea Nephrops fishery produces large amounts of invertebrate discards. Of these, as much as 89% are decapod crustaceans, including the swimming crab Liocarcinus depurator (Linnaeus, 1758), the squat lobster Munida rugosa (Fabricius, 1775) and the hermit crab Pagurus bernhardus (Linnaeus, 1758). The short-term mortality of these species was assessed following trawling and periods of aerial exposure on deck (16–90 min), and ranged from 2–25%, with Pagurus bernhardus showing the lowest mortality. Two experiments were performed to determine the longer-term survival of trawled decapods compared to those with experimentally ablated appendages. Deliberately damaged decapods had a significantly lower longer- term survival (ca. 30%) than controls (72–83%). Survival of trawled Liocarcinus depurator that had been induced to autotomize two appendages was slightly lower (74%) compared with intact creel-caught animals (92%). Mortality rates stabilised about 10 d after trawling. Our results suggest that post-trawling mortality of discarded decapod crustaceans has been underestimated in the past, owing to inadequate monitoring periods. 2001 International Council for the Exploration of the Sea Key words: by-catch mortality, trawling, discards, injury, autotomy, decapod crustaceans, Liocarcinus depurator, Munida rugosa, Pagurus bernhardus, Scotland, survival.

    MARINE ECOLOGY - PROGRESS SERIES Vol. 31: 87-99, 1986 Published June 19 Mar. Ecol. Prog. Ser. l - - Natural diet and feeding habits of the crabs Liocarcinus puber and L. holsatus (Decapoda, Brachyura, Portunidae) Satish C. Choy Marine Science Group, University College of Swansea, Singleton Park. Swansea SA2 8PP, Wales, United Kingdom mSTRACT: The foregut volumes of locarcinuspuber and L. holsatus were related to body size as y = 0.0338e~~~~xand y = 0.0313e00598xrespectively, where y = foregut volume (m]) and X = carapace width (mm).The amount of food remaining in the foregut of these crabs decreased exponenhally with time so that for both species the foregut was half empty about 5 h after feeding and almost empty about 20 h later (T = 13.5 f 1.5"C).However, shell fragments and algae were still found after 36 and 72 h, respectively. Crustaceans (mainly crabs and barnacles) were the most important food group of juvenile L. puber, and brown algae (Laminaria and Fucus spp.) and bivalve n~olluscs(esp Myhlus edulis) were the next 2 important groups. Algae were found predonunantly In crabs >25 mm CW. The main food group of adult L. puber was brown algae (Lamlnaria and Fucus spp ), occurring in about 80 O/O of the foreguts examined and constitutmg over 40 % of the total volunle of diet (the highest ever recorded for portunid crabs). The next 2 major groups in their diet were crustaceans (anomuran crabs) and molluscs (M. edulis). Results strongly suggest that L. puber feeds selectively on algae and can also digest them.

  • Distribution of Liocarcinus Depurator Along the Western Mediterranean Coast
    DISTRIBUTION OF LIOCARCINUS DEPURATOR ALONG THE WESTERN MEDITERRANEAN COAST By Marta M. Rufino A thesis submitted to the University of Wales, Bangor. School of Ocean Sciences for the degree of Doctor in Philosophy This thesis is dedicated to my mum, without whom none would have been possible Summary The distribution of L. depurator has been analysed through classical statistics, linear models and geostatistics. Density was obtained from a ten-year time series of bottom, otter trawl surveys in eight areas along the Mediterranean coast of Spain. Two peaks of L. depura- tor occurrence were observed. The first (80% occurrence) between 51 and 150 m, and the other (66% occurrence) between 301 and 400 m. Below 500 m, crab occurrence was negligi- ble (<8%) and densities fell sharply. The pattern shown by crab densities closely shadows that of occurrence, although a second abundance peak was barely evident, and was located at 201- 300 m. From 200-400 m, crab abundance appeared fairly evenly distributed but showing lower densities than in shallower waters. Analysis through linear modelling showed that L. depurator density decreased signifi- cantly with depth and year, but no effect of sample location was evident. The decrease of L. depurator density was most pronounced at shallower depths (depths < 150 m, declining at ~8±1 % per annum), than in deeper waters (depths > 150 m, declining at ~4±1 % per annum). Geostatistical analysis of L. depurator densities showed that the crabs distributions ex- hibited varying degrees of spatial structure with patch sizes varying between 19 and 75 km among the sampled years.

  • Handling Methods Used by the Velvet Swimming Crab Liocarcinus Puber
    ECOLOGY PROGRESS SERIES Vol. 25: 63-70, 1985 MARINE - Published August 15 Mar. Ecol. Prog. Ser. Handling methods used by the velvet swimming crab Liocarcinus puber when feeding on molluscs and shore crabs T. ap Rheinallt* & R. N. Hughes School of Animal Biology. University College of North Wales. Bangor, Gwynedd LL57 2UW, United Kingdom ABSTRACT: Velvet swimming crabs Liocarnnus puber, collected in Gwynedd, N. Wales, were observed feeding in the laboratory on winkles Littorina rudis, mussels Mytilus edulis, and juvenile shore crabs Carcinus maenas. Handling methods were recorded, and for mussels and shore crabs only. handling times were measured. Since C. maenas is mobile and can escape from some attacks, attack success rate was quantified for this prey. Specific methods for opening larger molluscs were apparently determined by geometry and strength of shell, which limited the positions in which the chela could exert sufficient force without slipping. No specialized opening techniques existed for small molluscs, which were crushed outright, and for shore crabs, which were torn apart without difficulty. Total handling time for both prey types was described by the equation y = ax + b, where y = log(time); X = prey length or carapace width/log(predator carapace width). Handling time of M. edulisconsisted of 3 components. Breaking and eating times of large mussels were positively correlated with prey size; breaking time of small mussels, which could be crushed with a single application of force, was independent of prey size. Picking-up time was short, and negatively correlated with prey size. indicating that L. puber, due to lack of chelal dexterity, had difficulty picking up smaller prey.
