Suas diferenças sistemáticas originaram as Ordens: Thecosomata e Gymnosomata. Os primeiros possuem conchas cônicas de forma variada, pseudoconcha e desnudos, enquanto os Gymnosomata caracterizam-se pela ausência delas na fase adulta. O objetivo do trabalho é conhecer a estrutura da comunidade dos Thecosomata e Gymnosomata planctônicos no Atlântico Sudoeste Tropical. O material foi coletado durante a IV Expedição Oceanográfica do Programa REVIZEE (Avaliação do Potencial Sustentável de Recursos Vivos da Zona Econômica Exclusiva), nos meses de setembro e dezembro de 2000. A área estudada está localizada entre 00º46’45”N a 13º53’45”S - 29º15’40”W a 39º49’42”W, onde foram realizados seis cruzeiros, totalizando 123 estações. As amostras foram coletadas em rede tipo bongo de malha de 300 μm no estrato de 0 a 200 m, com duração de 15 min até sua chegada à superfície. A bordo, as amostras foram acondicionadas de acordo com a metodologia. Em laboratório, as amostras foram analisadas. A bordo, as amostras foram acondicionadas, etiquetadas e fixadas. Em laboratório, as amostras foram analisadas, as espécies identificadas e medidas. Foram examinados 8.291 indivíduos pertencentes às ordens Thecosomata e Gymnosomata distribuídos: 4 superfamílias, 12 famílias e 41 espécies. Não há registro de espécies novas, mas registro de novas ocorrências para as águas do Nordeste brasileiro. Thecosomata foi o clado mais representativo, pelo maior número de indivíduos coletados e diversidades de espécies. Os Gymnosomata foram pouco abundantes e raros. Heliconoides inflatus e Diacavolinia longirostris se destacaram em número de espécimes, frequência e abundância, dominando a área do Nordeste brasileiro.

80	Ontogenetic correlation between muscle and nervous system novelties in a neritimorph gastropod Ferguson, Samuel 14 August 2015 (has links) Hatching larvae of neritimorph gastropods have a bilateral set of both larval and pedal retractor muscles, which is unique among gastropod molluscs. Adults also display a novel connection (“shortcut”) between the two pleural ganglia. To reconstruct the evolution of the novel shortcut between pleural ganglia and its functional role, I studied the development of the central nervous system and muscle innervation in three distinct larval and one post-metamorphic stages of Nerita melanotragus using light and transmission electron microscopy and surface-rendered three-dimensional reconstructions. My results revealed that the novel shortcut is derived from an ancestral nerve connective, which establishes an unconventional link between the ganglia that generate motor output to the bilateral set of larval and pedal retractor muscles to coordinate activity of these muscles. The unique characteristics of the shell, muscles and nervous system in N. melanotragus represent secondarily derived characteristics that co- evolved as an integrated functional unit. / Graduate / 0472 evolution development nervous system morphology gastropoda mollusca
