Introduction Whereas the concept of ecosystem services is popularized, scientists and environmentalists often confound their perception of biodiversity by neglecting the importance of taxonomy. When considering the different components of biodiversity, the study of species diversity is a time-consuming activity, which can become a considerable challenge for some taxonomic groups, particularly in regions where large gaps of knowledge and lack of expertise exist [1, 2]. In the past two decades, after the emergence of the DNA barcoding concept, naturalists, and even more taxonomists, have developed new concepts and techniques, such as the so-called ªintegrative taxonomy and systematicsº, to maintain or even improve their effort in describing new species or assemblages. Sponges inhabit all types of aquatic, benthic ecosystems. They can dominate the ocean floors in terms of living biomass and species richness, thus shaping polar, temperate and tropical seascapes [3±5]. In these cases, they are considered keystone components of benthic ecosystem functioning, and powerful suspension feeders, consuming wide ranges of dis- solved and particulate organic matter from the pico-, nano- and micro-planktonic commu- nities Depending on the biogeographic region, they experience either anecdotic (temperate seas) or significant predatory pressures (tropical seas) by sea-slugs, fishes and sea-turtles, among other predators [e.g. 6±8]. In tropical regions, which are usually hotspots of sponge diversity, knowledge of these organisms may be crucial to better understand the putative effects of the global or regional changes, namely climatic anomalies, overfishing or pollution. Sponges are well known to suffer disease outbreaks [9], and are also sometimes considered as key biotic factors threatening endangered reef-building corals [10±12]. In addition, it is also well accepted that sponges provide goods and services with societal benefit. For example, the fact that they are the source of chemical compounds with human health applications stimulates the maintenance of the taxonomic expertise required to describe sponge species diversity. Moreover, their ability to depurate xenobiotics [e.g. 12±14] further justifies the conservation

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).

E-mail: [email protected], Tel.: +49 (0) 89 2180 6635; Fax: +49 (0) 89 2180 6601 Abstract The diversity and phylogenetic relationships of calcareous sponges are still not completely understood. Recent integrative approaches combined analyses of DNA and morphological observations. Such studies resulted in severe taxonomic revi- sions within the subclass Calcinea and provided the foundation for a phylogenetically meaningful classification. However, several genera are missing from DNA phylogenies and their relationship to other Calcinea remain uncertain. One of these genera is Leuclathrina (family Leucaltidae). We here describe a new species from the Maldives, Leuclathrina translucida sp. nov., which is only the second species of the genus. Like the type species Leuclathrina asconoides, the new species has a leuconoid aquiferous system and lacks a specialized choanoskeleton.

Gemmule formation allows the sponge to overcome critical environmental conditions, for example, desiccation or freezing, and to re-establish as a fully developed sponge when conditions are more favorable. A key process in sponge development from hatched gemmules is the construction of the silica skeleton. Silica spicules form the structural support for the three-dimensional filtration system the sponge uses to filter food particles from Submitted 30 August 2018 ambient water.

Bell (Primary supervisor) & Professor Simon K. Davy (Co-supervisor) Victoria University of Wellington Wellington, New Zealand ABSTRACT Understanding the evolutionary forces that shape populations in the marine environment is critical for predicting population dynamics and dispersal patterns for marine organisms. For organisms with complex reproductive strategies, this remains a challenge. Sponges fulfil many functional roles and are important components of benthic environments in tropical, temperate and polar oceans. They have evolved diverse reproductive strategies, reproducing both sexually and asexually, and thus provide an opportunity to investigate complicated evolutionary questions. This PhD thesis examines sexual and asexual reproduction in two common golf-ball sponges in central New Zealand (Tethya bergquistae and T. burtoni), with particular focus on how the environment influeunces these modes of reproduction, and further, how they shape species delineations and connectivity patterns. New Zealand waters are projected to experience increases in temperature and decreases in nutrients over the next century, and therefore these species may be experience changes in basic organismal processes like reproduction due to climate change, requiring adaptation to local environments. Therefore, this work has important implications when considering how reproductive phenology, genetic diversity and population structure of marine populations may change with shifts in climate.

E-mail: [email protected] Abstract Although the French Polynesian reefs are among the most well studied reefs of the world, sponges are still poorly known, with only 199 species or OTUs of sponges having been described from French Polynesia, 167 at an OTU level and 32 at a species level. From those 199 species, just five are calcareous sponges. As it is possible that this number is underestimated, the aim of the present work was to study the diversity of calcareous sponges from French Polynesia. Hence, different French Polynesian archipelagos were surveyed by SCUBA from 3 to 60 m of depth. Identifications were performed using morphological and molecular (ITS and C-LSU) tools. We found a total of nine species of Calcarea, comprising five different genera.

Helena Ćetković Kratki sažetak doktorske disertacije: Molekularna istraživanja doprinose brojnim izmjenama u taksonomiji pojedinih skupina životinja čiji se srodstveni odnosi temelje na morfološkim obilježjima. Mnoge slatkovodne spužve i spužve vapnenjače pogrešno su determinirane na temelju morfologije te su neophodne popratne molekularne analize. Analiza palindromskih elemenata u intergenskim regijama mitohondrijskih genoma slatkovodnih spužvi pokazuje da su porodice tih elemenata vjerojatno evolucijski povezane. Na osnovu molekularnih markera u kombinaciji s morfološkim obilježjima, u ovom je radu opisano 6 novih vrsta vapnenjača.
