In the complex and rich Northeast (NE) Atlantic and Macaronesia coasts, the superoder Peracarida (Crustacea) is one of the most abundant and commom marine invertebrate taxa with an important role in benthic communities. The study of this group is often limited to inventory lists or benthic community studies and the genetic knowledge of the group in this region is poor. The main goal of this thesis was to improve knowledge on Peracarida diversity and evolution in the NE Atlantic and Macaronesia, with particular emphasis on shallow water and rocky shore members of the orders Amphipoda, Isopoda and Tanaidacea. The thesis comprises five chapters with original research, entailing a DNA barcode-based screening of the species diversity in this group through the comparison of morphology and molecular-derived data (chapter 2), a set of two studies of the isopod genus Dynamene (chapters 3 and 4), one chapter about the amphipod family Hyalidae (chapter 5), and a multi-species analyses of the diversity and broad phylogeographic patterns of Macaronesian peracarideans (chapter 6). In the first chapter, we reported a DNA barcode reference library for the superorder Peracarida, comprising specimens from marine Atlantic coasts, mainly from Iberian Peninsula, together with additional members of the same or sister taxa from other locations. A higher number of Barcode Index Numbers (BINs) compared with the number of morphospecies was found, with some of them displaying up to six BINs. The presence of deeply divergent intraspecific lineages suggests the existence of considerable overlooked taxonomic diversity, even in one of the most well-known peracaridean faunas in the world. These findings indicate the need for a broad, comprehensive and integrated revision of the peracaridean fauna from the Southern European Atlantic coasts. In the second chapter, the commom but species-poor and controversial isopod Dynamene genus was investigated in detail by examining thousands of specimens records sampled during more than fifty years. The distribution and taxonomy of the six Dynamene species along the Northeast Atlantic-Black Sea axis was revised and updated. New distribution maps and illustrated keys to the adult males and females of the northern hemisphere species are provided. In the last three chapters, molecular delineation tools revealed extensive cryptic diversity in the genus Dynamene (3 morphospecies vs 12 molecular operational taxonomic units - MOTUs), in the amphipod family Hyalidae (7 morphospecies vs 32 MOTUs) and in twenty-five peracaridean species (25 morphospecies vs 90 MOTUs). A split between Macaronesian and continental populations was patent, and in most cases the Macaronesian populations displayed high levels of diversity. These findings suggest a much larger role of oceanic islands in the diversification of these marine invertebrates than would have been anticipated, and contributes to expose weakly explored events in the phylogeography and evolution of Macaronesia's marine fauna. This thesis showed that marine biodiversity, as seen in peracarideans from the NE Atlantic and Macaronesia, has been considerably underestimated. The level of diversity will likely increase with the addition of different taxa, different types of habitat and distinct marine regions. It also suggests that these oceanic islands may act as drivers of evolution, diversification and endemism, just as well for marine organisms as they do for terrestrial ones.

520 $a Nas costas complexas e ricas do Nordeste (NE) Atlantico e da Macaronesia, a superordem Peracarida (Crustacea) e um dos taxa de invertebrados marinhos mais abundante e comum, com um papel importante nas comunidades bentonicas. O estudo deste grupo e muitas vezes limitado a listas de inventarios ou estudos de comunidade bentonicas e o seu conhecimento genetico nesta regiao e deficiente. O objetivo principal desta tese foi o de melhorar o conhecimento sobre a diversidade e a evolucao dos peracarideos no Atlantico Nordeste e na Macaronesia, com enfase nos membros presentes nas zonas pouco profundas e nas zonas costeiras rochosas das ordens Amphipoda, Isopoda e Tanaidacea. Esta tese compreende cinco capitulos com pesquisa original, incluindo uma biblioteca de referencia de DNA barcodes neste grupo, atraves da comparacao de dados morfologicos e moleculares (capitulo 2), um conjunto de dois estudos dedicados ao genero isopode Dynamene (capitulos 3 e 4), um capitulo dedicado a familia de anfipodes Hyalidae (capitulo 5), e uma abordagem multi-especies da diversidade e dos padroes filogeograficos dos peracaridios presentes na Macaronesia (capitulo 6). No primeiro capitulo, relatamos uma biblioteca de referencia de DNA barcodes para a superordem Peracarida, que inclui especimes de costas do Atlantico, principalmente da Peninsula Iberica, juntamente com membros adicionais do mesmo ou semalhantes taxa de outros locais. Um maior numero de Barcode Index Numbers (BINs) em comparacao com o numero de morfo-especies foi encontrado, com algumas morfo-especies exibindo ate seis BINs. A presenca de linhagens profundamente divergentes sugere a existencia de uma consideravel diversidade taxonomica anteriormente negligenciada, mesmo numa das mais conhecidas faunas de peracarideos do mundo. Estas descobertas indicam a necessidade de uma revisao ampla, abrangente e integrada da fauna de peracarideos das costas do Atlantico do Sul da Europa. No segundo capitulo, o abundante mas controverso genero Dynamene foi investigado em detalhe, ao examinar varios milhares de individuos amostrados durante mais de cinquenta anos. A distribuicao e a taxonomia das seis especies de Dynamene ao longo do eixo Nordeste Atlantico-Mar Negro foram revistas e actualizadas. Novos mapas de distribuicao e chaves ilustradas para os machos adultos e femeas das especies deste genero, presentes no hemisferio norte, sao fornecidas. Nos tres ultimos capitulos, as ferramentas de delineamento molecular revelaram uma extensa diversidade criptica no genero Dynamene (3 morfoespecies vs 12 unidades taxonomicas operacionais moleculares - MOTUs), na familia de anfipipodes Hyalidae (7 morfoespecies vs 32 MOTUs) e em vinte e cinco especies de peracarideos (25 morfoespecies vs 90 MOTUs). Uma separacao entre as populacoes presentes na Macaronesia e as presentes no continente foi visivel e, na maioria dos casos, as populacoes presentes na Macaronesia apresentavam maiores niveis de diversidade. Estas descobertas sugerem um papel maior das ilhas oceanicas na diversificacao destes invertebrados marinhos do que se anteciparia e contribuiram para expor eventos pouco explorados na filogeografia e evolucao da fauna marinha na Macaronesia. Esta tese mostrou que a biodiversidade marinha, como se observa em peracarideos presentes no NE Atlantico e na Macaronesia, foi consideravelmente subestimada. O nivel de diversidade provavelmente aumentara com a adicao de diferentes taxa, diferentes tipos de habitat e de regioes marinhas distintas. Esta tese tambem sugere que estas ilhas oceanicas podem atuar como impulsionadoras da evolucao, da diversificacao e do endemismo em organismos marinhos, como acontece nos organismos terrestres.
