P. Payne MSc Thesis, Department of Biodiversity and Conservation Biology, University of the Western Cape. Seamounts are poorly understood ubiquitous undersea features, with less than 4% sampled for scientific purposes globally. Consequently, the fauna associated with seamounts in the Indian Ocean remains largely unknown, with less than 300 species recorded. One such feature within this region is Walters Shoal, a shallow seamount located on the South Madagascar Ridge, which is situated approximately 400 nautical miles south of Madagascar and 600 nautical miles east of South Africa. Even though it penetrates the euphotic zone (summit is 15 m below the sea surface) and is protected by the Southern Indian Ocean Deep- Sea Fishers Association, there is a paucity of biodiversity and oceanographic data. -

Appendix: Some important early collections of West Indian type specimens, with historical notes Duchassaing & Michelotti, 1864 between 1841 and 1864, we gain additional information concerning the sponge memoir, starting with the letter dated 8 May 1855. Jacob Gysbert Samuel van Breda A biography of Placide Duchassaing de Fonbressin was (1788-1867) was professor of botany in Franeker (Hol published by his friend Sagot (1873). Although an aristo land), of botany and zoology in Gent (Belgium), and crat by birth, as we learn from Michelotti's last extant then of zoology and geology in Leyden. Later he went to letter to van Breda, Duchassaing did not add de Fon Haarlem, where he was secretary of the Hollandsche bressin to his name until 1864. Duchassaing was born Maatschappij der Wetenschappen, curator of its cabinet around 1819 on Guadeloupe, in a French-Creole family of natural history, and director of Teyler's Museum of of planters. He was sent to school in Paris, first to the minerals, fossils and physical instruments. Van Breda Lycee Louis-le-Grand, then to University. He finished traveled extensively in Europe collecting fossils, especial his studies in 1844 with a doctorate in medicine and two ly in Italy. Michelotti exchanged collections of fossils additional theses in geology and zoology. He then settled with him over a long period of time, and was received as on Guadeloupe as physician. Because of social unrest foreign member of the Hollandsche Maatschappij der after the freeing of native labor, he left Guadeloupe W etenschappen in 1842.

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). -
2020 Annual Report
EMBRC: 2020 annual report Marine biodiversity is becoming an increasing concern with climate change and marine pollution, and, as a result, is of high relevance in the forthcoming UN Decade of the Ocean and Europe’s Green Deal. One of EMBRC’s principal activities is the provision of access to marine biodiversity, in all its forms. EMBRC Operators include some of the oldest marine institutes in the world and operate long-term observations, host biodiversity monitoring activities, and conduct research. In order to provide holistic information on biodiversity composition at these sites, EMBRC will establish EMO BON, a coordinated European Marine Omics Biodiversity Observation Network across its partners. This will constitute a new approach for EMBRC, and a step in a new direction, toward data generation and long-term observation. EMO BON presents an important need for the EMBRC user community and the opportunity to start filling the void in biological observation that we currently face in regard to physical and chemical observation. This is also an exciting opportunity to generate data for the marine microbiome studies currently in progress, and support Atlantic strategies, such as the Atlantic Ocean Research Alliance (AORA). Knowledge-based management of our blue planet is only possible by unified global monitoring using comparable data, which, in the case of biodiversity, cannot currently be assessed by remote sensing. In this context, EMBRC wishes to contribute to the global coordination of marine biodiversity by –omics approaches, integrating forthcoming technologies as appropriate. We aim to reach and interact with other relevant initiatives, offering the advantages of a sustainable RI that can support active research and underpin the development and optimisation of new methods. -

Phylogenetic Analyses of Marine Sponges Within the Order Verongida: a Comparison of Morphological and Molecular Data
Invertebrate Biology 126(3): 220–234. r 2007, The Authors Journal compilation r 2007, The American Microscopical Society, Inc. DOI: 10.1111/j.1744-7410.2007.00092.x Phylogenetic analyses of marine sponges within the order Verongida: a comparison of morphological and molecular data Patrick M. Erwin and Robert W. Thackera University of Alabama at Birmingham, Birmingham, Alabama 35294, USA Abstract. Because the taxonomy of marine sponges is based primarily on morphological characters that can display a high degree of phenotypic plasticity, current classifications may not always reflect evolutionary relationships. To assess phylogenetic relationships among sponges in the order Verongida, we examined 11 verongid species, representing six genera and four families. We compared the utility of morphological and molecular data in verongid sponge systematics by comparing a phylogeny constructed from a morphological character matrix with a phylogeny based on nuclear ribosomal DNA sequences. The morphological phylogeny was not well resolved below the ordinal level, likely hindered by the paucity of characters available for analysis, and the potential plasticity of these characters. The molec- ular phylogeny was well resolved and robust from the ordinal to the species level. We also examined the morphology of spongin fibers to assess their reliability in verongid sponge tax- onomy. Fiber diameter and pith content were highly variable within and among species. Despite this variability, spongin fiber comparisons were useful at lower taxonomic levels (i.e., among congeneric species); however, these characters are potentially homoplasic at higher taxonomic levels (i.e., between families). Our molecular data provide good support for the current classification of verongid sponges, but suggest a re-examination and potential reclas- sification of the genera Aiolochroia and Pseudoceratina.
