These concepts are useful for the understanding of the general picture presented in this PhD. The origin and fate of TE in different compartments of the aquatic system are presented as well as a brief description of analytical techniques used during the present work. 12 PART I: GENERAL INTRODUCTION 13 PART I: GENERAL INTRODUCTION 1. TRACE ELEMENTS IN THE ENVIRONMENT The IUPAC Compendium of Chemical Terminology defines trace element as “any element having an average concentration of less than about 100 parts per million atoms or less than 100 µg g-1’’ (McNaught and Wilkinson, 1997). Among TE, some are oligo elements and are thus considered essential for various biochemical and physiological functions within a certain range of concentrations. Metals/metalloids considered by World Health Organization to be essential for human health are: chromium, cobalt, copper, iron, molybdenum, selenium and zinc (WHO, 1996)(WHO, 1996).On the other hand, other TE are considered toxic at any concentration (Hg, Pb, Cd) (WHO/FAO/IAEA, 1996). These elements are naturally present in the ecosystem because of natural processes such as weathering and erosion but also volcanic activity. Nevertheless, in the last decades, several anthropogenic activities have increased the loads of these elements in the environment (Bagul, 2015). Main anthropogenic sources of TE include metal mining, mineral processing, smelting, coal mining, power generation but also municipal waste incinerators, industrial waste of

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.

    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 reasons for these outbreaks are still unclear, as are long-term prognoses of affected reefs. Some reports have suggested outbreaks may not be permanent, but very little long-term monitoring information exists. In this study, we report on a T. hoshinota outbreak (~24% coverage) at Yakomo, Okinoerabu-jima Island, Kagoshima, Japan between 2010 to 2014.

    Project Title Using genetic techniques to determine the unknown diversity and possible alien origin of sponges present in Hawaii Agency, Division University of Hawaii, Hawaii Institute of Marine Biology Total Amount Requested $114,200 Amount Awarded $49,145 Applicants (First and Last Name) Robert Toonen & Jan Vicente Applicant Email Address [email protected] Project Start Date 1-Oct-18 Estimated Project End Date 31-May-20 Efforts to detect and prevent alien introductions depend on understanding which species are already present1–3. This is particularly important when working with taxonomically challenging groups like marine sponges (phylum Porifera), where morphological characters are highly limited, and misidentifications are common4. Although sponges are a major component of the fouling community, they remain highly understudied because they are so difficult to identify4. The Keyhole Sponge is already present in Hawaiʻi5,6, but others like Terpios hoshinota, which is invading many locations across the Pacific7,8, kills corals and turns the entire reefscape into a gray carpet that would be devastating to Hawaiʻi tourism if introduced here. However, many gray sponges look alike, and it is only through the combined use of morphological and genetic characters that most sponges can be identified reliably4. To date, there have been very few taxonomic assessments of sponges in Hawaiʻi9–14, and only the most recent of these has included any DNA barcodes in an effort to confirm the visual identifications15. Most of the early studies did not provide museum specimens or even detailed descriptions about how the species were identified, and the few vouchers that exist from these studies were dried which precludes DNA comparisons.

A total 83 species were identified representing 6 phyla, belonging to12 classes, 34 orders and 50 families were recorded from Ratnagiri coast. Results showed that mollusca exhibited highest contribution with 46 species with 55% of the total diversity. Phylum porifera appeared as the second most dominant group contributed 12 species with 15% diversity, Coelenterates comprised 10 species with 12% and Arthropods contributed 10 species with 12% diversity, Echinodermata 3 species with 4% and last Annelids 2 species with 2% of the total diversity. The diversity of macrofaunal group in prevalence of different habitats a wide chance of research to further explore on the possibility of ecological value and there conservation. Keywords: Diversity, Intertidal zone, Macrofaunal assemblage, Ratnagiri Coast. I. INTRODUCTION The intertidal zone of any ecological area is considered as the most productive with the greatest diversity of plant and animal life. Because of its accessibility, the intertidal zone remain highly explored than any other area (Vaghelaet al., 2010). Rocky shores are the most extensive littoral habitats exposed to eroding waves and thus are ecologically very important (Crowe, et al., 2000).
