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. -

Supplementary Materials: Patterns of Sponge Biodiversity in the Pilbara, Northwestern Australia
Diversity 2016, 8, 21; doi:10.3390/d8040021 S1 of S3 9 Supplementary Materials: Patterns of Sponge Biodiversity in the Pilbara, Northwestern Australia Jane Fromont, Muhammad Azmi Abdul Wahab, Oliver Gomez, Merrick Ekins, Monique Grol and John Norman Ashby Hooper 1. Materials and Methods 1.1. Collation of Sponge Occurrence Data Data of sponge occurrences were collated from databases of the Western Australian Museum (WAM) and Atlas of Living Australia (ALA) [1]. Pilbara sponge data on ALA had been captured in a northern Australian sponge report [2], but with the WAM data, provides a far more comprehensive dataset, in both geographic and taxonomic composition of sponges. Quality control procedures were undertaken to remove obvious duplicate records and those with insufficient or ambiguous species data. Due to differing naming conventions of OTUs by institutions contributing to the two databases and the lack of resources for physical comparison of all OTU specimens, a maximum error of ± 13.5% total species counts was determined for the dataset, to account for potentially unique (differently named OTUs are unique) or overlapping OTUs (differently named OTUs are the same) (157 potential instances identified out of 1164 total OTUs). The amalgamation of these two databases produced a complete occurrence dataset (presence/absence) of all currently described sponge species and OTUs from the region (see Table S1). The dataset follows the new taxonomic classification proposed by [3] and implemented by [4]. The latter source was used to confirm present validities and taxon authorities for known species names. The dataset consists of records identified as (1) described (Linnean) species, (2) records with “cf.” in front of species names which indicates the specimens have some characters of a described species but also differences, which require comparisons with type material, and (3) records as “operational taxonomy units” (OTUs) which are considered to be unique species although further assessments are required to establish their taxonomic status. -

Demospongiae: Dictyoceratida: Thorectidae) from Korea
Journal of Species Research 9(2):147-161, 2020 Seven new species of two genera Scalarispongia and Smenospongia (Demospongiae: Dictyoceratida: Thorectidae) from Korea Young A Kim1,*, Kyung Jin Lee2 and Chung Ja Sim3 1Natural History Museum, Hannam University, Daejeon 34430, Republic of Korea 2Animal Resources Division, National Institute of Biological Resources, Incheon 22689, Republic of Korea 3Department of Biological Sciences and Biotechnology, Hannam University, Daejeon 34430, Republic of Korea *Correspondent: [email protected] Seven new species of two genera Scalarispongia and Smenospongia (Demospongiae: Dictyoceratida: Thorectidae) are described from Gageo Island and Jeju Island, Korea. Five new species of Scalarispongia are compared to nine reported species of the genus by the skeletal structure. Scalarispongia viridis n. sp. has regular ladder-like skeletal pattern arranged throughout the sponge body and has pseudo-tertiary fibres. Scalarispongia favus n. sp. is characterized by the honeycomb shape of the surface and is similar to Sc. flava in skeletal structure, but differs in sponge shape. Scalarispongia lenis n. sp. is similar to Sc. regularis in skeletal structure but has fibers that are smaller in size. Scalarispongia canus n. sp. has irregular skeletal structure in three dimensions and ladder-like which comes out of the surface and choanosome. Scalarispongia subjiensis n. sp. has pseudo-tertiary fibres and its regular ladder-like skeletal pattern occurs at the choanosome. Two new species of Smenospongia are distinguished from the other 19 reported species of the genus by the skeletal structure. Smenospongia aspera n. sp. is similar to Sm. coreana in sponge shape but new species has rarely secondary web and thin and thick bridged fibres at near surface. -
“Diversity and Specificity of the Marine Sponge Microbiome As Inspected by Next Generation Sequencing”
“DIVERSITY AND SPECIFICITY OF THE MARINE SPONGE MICROBIOME AS INSPECTED BY NEXT GENERATION SEQUENCING” André Rodrigues Soares Mestrado em Biologia Molecular e Microbiana Trabalho efetuado sob a orientação de: Dr. Rodrigo da Silva Costa Prof.ª Dr.ª Maria Margarida dos Prazeres Reis 2015 Acknowledgements For the completion of the present work, the support of the Microbial Ecology and Evolution (MicroEcoEvo) research group at the CCMAR was crucial. Firstly, I thank Rodrigo Costa, my supervisor, who drew me into the field of microbial ecology of marine sponges and posed me the great challenge of tackling the EMP dataset. Furthermore, I am thankful for all the enthusiasm and opportunities provided and for the immense patience! Gianmaria Califano, now in Jena, Austria, and Asunción Lago- Lestón dispensed precious time and patience in the starting phase of this thesis. I further thank Elham Karimi for the help in the laboratory and for our relaxing coffee talks! Tina Keller-Costa, Telma Franco and more recently Miguel Ramos, along with the abovementioned, are all part of the MicroEcoEvo team, to whom I thank for a wonderful first medium-term experience in a laboratory! I admittedly started my Biology Bsc. at the University of Algarve not being fond of any biological entity smaller than 2cm. It was Prof. Margarida Reis (Microbial and Molecular Ecology Laboratory, CIMA, UAlg) who showed me that ‘microbes can do anything’ and went on to accepting the challenge of supervising my Bsc. Technical and Scientific Project. I therefore thank her for introducing me to Microbiology in the best way possible. For the completeness of this work, Lucas Moitinho-Silva (currently at the University of South Wales, Australia), was essential in introducing me to R scripting whilst finishing his PhD at Wüezburg University, Germany. -

Nevertheless, our understanding of this microbiota remains limited to a few host species found in restricted geographical localities, and the extent to which the sponge host determines the composition of its own microbiome remains a matter of debate. We address bacterial abundance and diversity of two temperate marine sponges belonging to the Irciniidae family - Sarcotragus spinosulus and Ircinia variabilis – in the Northeast Atlantic. Epifluorescence microscopy revealed that S. spinosulus hosted significantly more prokaryotic cells than I. variabilis and that prokaryotic abundance in both species was about 4 orders of magnitude higher than in seawater. -

On the Current Status of Spongia Officinalis (The Sponge by Definition) -.:: GEOCITIES.Ws
CHAPTER 1 On the current status of Spongia officinalis (the sponge by definition), and implications for conservation. A review Roberto Pronzato [Università di Genova] 1 and Renata Manconi [Università di Sassari] 2 Keywords: Endangered species; Bath sponges; Mediterranean Sea; Over-fishing; Sponge Disease; Sponge Farming; Porifera. Abstract: Spongia officinalis is, and will remain, the oldest nominal species of the phylum Porifera, and its name is the only one still valid among those originally described by Linnaeus. As for the biogeographic pattern, records of S. officinalis are known at the global scale, but its geographic range is probably restricted to the Mediterranean Sea. Over 500 taxa have been described under the genus Spongia, but only 41 species are verifiably valid. S. officinalis is notably plastic. Due to re-modelling of morphotraits, it is difficult to describe it in a precise and accurate way and to distinguish and identify it among the many other Mediterranean and extra- Mediterranean bath sponge species. An irreversible depletion of the bath sponge banks of the Mediterranean Sea, due to the combined effects of over-fishing and disease, has brought several populations to the brink of extinction since the mid-1980s. The recovery of affected populations has been long and difficult, despite the sponge’s extraordinary regenerative capability due to the perennial morphogenesis of the sponge body. S. officinalis has undergone a major population decline. Since 1999 the situation has evolved dramatically for S. officinalis, and some of the few populations for which ascertained historical data are available are definitely extinct in the Mediterranean. This could be considered the beginning of a final catastrophe. -

ABSTRACT In the early 1990s, widespread sponge mortality events occurred in the Florida Keys, USA. These mortality events were coincidental with successive blooms of the picoplanktonic cyanobacterium Synechococcus sp. Although the specific cause of sponge death remains unknown, we conclude that bloom conditions caused the death of these sponges. We documented the effects of the mortality events on sponge community biomass and followed the sponge population response of 23 species for up to 15 years (1991 - 2006). In doing so, we provide an unprecedented, long-term, and detailed view of sponge population dynamics in the Florida Keys, following a set of environmental conditions that caused widespread mortality. Abundance of many sponge species following the mortality events was dynamic and contrasts with work done on deep-water sponge communities that have shown such communities to be stable over long periods of time.
