Dichas estructuras proporcionan diferentes servicios como la defensa de la costa o la producción de energía, a expensas de la pérdida de hábitat natural, disminución de la biodiversidad y reducción del valor ecológico de las comunidades marinas entre muchos otros impactos. En la presente tesis hemos estudiado diversas comunidades bentónicas asociadas a distintas estructuras de defensa costera con la finalidad de incrementar el conocimiento de sus impactos sobre dichas comunidades naturales y contribuir al desarrollo de medidas de ecoingeniería. Nos enfocamos principalmente en el Mar de Alborán y la Bahía de Algeciras, incluyendo tres enfoques: 1) el estudio de la biota bentónica a nivel local, 2) el estudio de la biota bentónica a nivel regional y 3) un estudio trófico a nivel de comunidad y de individuo. A nivel local, los resultados obtenidos nos han permitido identificar factores abióticos y bióticos que determinan la biota sésil, macro- y meiobentónica. A nivel regional hemos podido reconocer patrones en el impacto de estas estructuras, identificar qué estructuras presentan mayor o menor valor ecológico, así como valorar los desafíos a los que se enfrenta el campo de la ingeniería ecológica. Finalmente, hemos descrito potenciales impactos a nivel trófico en una comunidad que a menudo juega papeles importantes en las redes tróficas (los anfípodos) y una especie clave del intermareal (la lapa Patella caerulea). Concluimos que las estructuras artificiales están generando una pérdida de biodiversidad a nivel local y regional, determinada por factores abióticos como la composición del sustrato o la rugosidad. Las escolleras de roca natural parecen ofrecer un valor ecológico superior al resto de estructuras artificiales. No obstante, es complicado predecir el impacto de un tipo de estructura concreta, dificultando el establecimiento de medidas de ecoingeniería a nivel global.

  • (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: the Genera Nodilittorina, Austrolittorina and Afrolittorina
    © Copyright Australian Museum, 2004 Records of the Australian Museum (2004) Vol. 56: 75–122. ISSN 0067-1975 The Subfamily Littorininae (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: The Genera Nodilittorina, Austrolittorina and Afrolittorina DAVID G. REID* AND SUZANNE T. WILLIAMS Department of Zoology, The Natural History Museum, London SW7 5BD, United Kingdom [email protected] · [email protected] ABSTRACT. The littorinine gastropods of the temperate southern continents were formerly classified together with tropical species in the large genus Nodilittorina. Recently, molecular data have shown that they belong in three distinct genera, Austrolittorina, Afrolittorina and Nodilittorina, whereas the tropical species are members of a fourth genus, Echinolittorina. Austrolittorina contains 5 species: A. unifasciata in Australia, A. antipodum and A. cincta in New Zealand, and A. fernandezensis and A. araucana in western South America. Afrolittorina contains 4 species: A. africana and A. knysnaensis in southern Africa, and A. praetermissa and A. acutispira in Australia. Nodilittorina is monotypic, containing only the Australian N. pyramidalis. This paper presents the first detailed morphological descriptions of the African and Australasian species of these three southern genera (the eastern Pacific species have been described elsewhere). The species-level taxonomy of several of these has been confused in the past; Afrolittorina africana and A. knysnaensis are here distinguished as separate taxa; Austrolittorina antipodum is a distinct species and not a subspecies of A. unifasciata; Nodilittorina pyramidalis is separated from the tropical Echinolittorina trochoides with similar shell characters. In addition to descriptions of shells, radulae and reproductive anatomy, distribution maps are given, and the ecological literature reviewed.

  • Proposal for a Revised Classification of the Demospongiae (Porifera) Christine Morrow1 and Paco Cárdenas2,3*
    Morrow and Cárdenas Frontiers in Zoology (2015) 12:7 DOI 10.1186/s12983-015-0099-8 DEBATE Open Access Proposal for a revised classification of the Demospongiae (Porifera) Christine Morrow1 and Paco Cárdenas2,3* Abstract Background: Demospongiae is the largest sponge class including 81% of all living sponges with nearly 7,000 species worldwide. Systema Porifera (2002) was the result of a large international collaboration to update the Demospongiae higher taxa classification, essentially based on morphological data. Since then, an increasing number of molecular phylogenetic studies have considerably shaken this taxonomic framework, with numerous polyphyletic groups revealed or confirmed and new clades discovered. And yet, despite a few taxonomical changes, the overall framework of the Systema Porifera classification still stands and is used as it is by the scientific community. This has led to a widening phylogeny/classification gap which creates biases and inconsistencies for the many end-users of this classification and ultimately impedes our understanding of today’s marine ecosystems and evolutionary processes. In an attempt to bridge this phylogeny/classification gap, we propose to officially revise the higher taxa Demospongiae classification. Discussion: We propose a revision of the Demospongiae higher taxa classification, essentially based on molecular data of the last ten years. We recommend the use of three subclasses: Verongimorpha, Keratosa and Heteroscleromorpha. We retain seven (Agelasida, Chondrosiida, Dendroceratida, Dictyoceratida, Haplosclerida, Poecilosclerida, Verongiida) of the 13 orders from Systema Porifera. We recommend the abandonment of five order names (Hadromerida, Halichondrida, Halisarcida, lithistids, Verticillitida) and resurrect or upgrade six order names (Axinellida, Merliida, Spongillida, Sphaerocladina, Suberitida, Tetractinellida). Finally, we create seven new orders (Bubarida, Desmacellida, Polymastiida, Scopalinida, Clionaida, Tethyida, Trachycladida).

The aim of this work was to describe for the first time the shallow subtidal sessile benthos on coastal defense structures in Crete (Eastern Mediterranean Sea) in order to identify potential differences in comparison to natural rocky substrates, adopting both a taxonomic and functional (i.e. macroalgal structural complexity) approach. Three shallow (1-3 m) localities were studied in the north coast and three in the south coast of the island (six localities in total).

  • A New Minute Ectosymbiotic Harpacticoid Copepod Living on the Sea Cucumber Eupentacta Fraudatrix in the East/Japan Sea
    A new minute ectosymbiotic harpacticoid copepod living on the sea cucumber Eupentacta fraudatrix in the East/Japan Sea Jisu Yeom1, Mikhail A. Nikitin2, Viatcheslav N. Ivanenko3 and Wonchoel Lee1 1 Department of Life Science, Hanyang University, Seoul, South Korea 2 A.N. Belozersky Institute of Physico-chemical Biology, Lomonosov Moscow State University, Moscow, Russia 3 Department of Invertebrate Zoology, Biological Faculty, Lomonosov Moscow State University, Moscow, Russia ABSTRACT The ectosymbiotic copepods, Vostoklaophonte eupenta gen. & sp. nov. associated with the sea cucumber Eupentacta fraudatrix, was found in the subtidal zone of Peter the Great Bay, East/Japan Sea. The new genus, Vostoklaophonte, is similar to Microchelonia in the flattened body form, reduced mandible, maxillule and maxilla, but with well-developed prehensile maxilliped, and in the reduced segmentation and setation of legs 1–5. Most appendages of the new genus are more primitive than those of Microchelonia. The inclusion of the symbiotic genera Microchelonia and Vostoklaophonte gen. nov. in Laophontidae, as well as their close phylogenetic relationships, are supported by morphological observations and molecular data. This is the third record of laophontid harpacticoid copepods living in symbiosis with sea cucumbers recorded from the Korean and Californian coasts.

  • Biogeography and Phylogeny of Chondrilla Species (Demospongiae) in Australia
    MARINE ECOLOGY PROGRESS SERIES Vol. 270: 117–127, 2004 Published April 14 Mar Ecol Prog Ser Biogeography and phylogeny of Chondrilla species (Demospongiae) in Australia Kayley M. Usher1,*, David C. Sutton1, Simon Toze2, John Kuo3, Jane Fromont4 1The Department of Microbiology, University of Western Australia, 35 Stirling Highway, Crawley, 6009 Western Australia, Australia 2CSIRO Land and Water, Underwood Avenue, Floreat, 6014 Western Australia, Australia 3The Centre for Microscopy and Microanalysis, University of Western Australia, 35 Stirling Highway, Crawley, 6009 Western Australia, Australia 4Western Australian Museum, Perth Cultural Centre, Perth, 6000 Western Australia, Australia ABSTRACT: The biogeography and phylogeny of Chondrilla (Porifera, Demospongiae) species in Australia is poorly understood. Until the present study was carried out, 4 Chondrilla species were thought to occur in the waters of Australia and its territories: C. australiensis, C. secunda, C. mixta and C. nucula. However, the type specimen of the latter comes from the Adriatic Sea, and it has always been uncertain whether this species is present in Australia. The difficulty in determining the number of species of Chondrilla and their biogeography is largely due to the paucity of phenotypic characters that are normally used for identification. To clarify the diversity and distribution of sponges in this genus in Australia, DNA sequence analysis was applied to samples of Chondrilla from around Australia and compared to C. nucula from the Mediterranean. Classical taxonomic tech- niques were used to confirm the molecular results. Evidence was found for 3 species of Chondrilla in the temperate southern oceans of Australia with one, C. australiensis, also extending into tropical waters.
