Skillings Dissertation Committee: Robert Toonen, Chairperson Brian Bowen Charles Birkeland Andrew Taylor Ronald Bontekoe i DEDICATION This dissertation is dedicated to my wife, Melissa Kay Skillings. ii ACKNOWLEDGEMENTS First, I would like to thank my committee members who provided essential guidance and encouragement throughout my graduate career. Foremost, I would like to thank my advisor and committee chair Rob Toonen. He has generously offered me a near endless supply of advice and guidance, as he does for anyone who knocks on his door. He also gave me the flexibility and encouragement needed to make getting two simultaneous graduate degrees possible. My graduate career has been very unconventional, and Rob has supported me every step of the way. I would like to thank Brian Bowen for giving me the structure I needed to succeed. Given my tendency to get lost in an always increasing number of projects, I would have never finished in a reasonable amount of time without his firm hand at setting deadlines and his enthusiastic encouragement to meet those deadlines. Rob and Brian gave me the perfect balance of freedom and focus that I needed to succeed. I would like to thank Chuck Birkeland for helping me to put my work in the larger perspective of coral reef ecosystems. Chuck also encouraged my philosophical and historical investigations into biology through insightful conversation; every time I saw he seemed to have a valuable and important text that he wanted to give me for my collection, many from his personal library. -
Yellow Coloured Mats from Lava Tubes of La Palma (Canary Islands, Spain
www.nature.com/scientificreports OPEN Yellow coloured mats from lava tubes of La Palma (Canary Islands, Spain) are dominated by Received: 27 July 2017 Accepted: 16 January 2018 metabolically active Actinobacteria Published: xx xx xxxx Jose L. Gonzalez-Pimentel1, Ana Z. Miller 1, Valme Jurado1, Leonila Laiz1, Manuel F. C. Pereira2 & Cesareo Saiz-Jimenez1 Microbial diversity in lava tubes from Canary Islands (Spain) has never been explored thus far ofering a unique opportunity to study subsurface microbiology. Abundant yellow coloured mats developing on coralloid speleothems in a lava tube from La Palma Islands were studied by next-generation sequencing and DNA/RNA clone library analyses for investigating both total and metabolically active bacteria. In addition, morphological and mineralogical characterization was performed by feld emission scanning electron microscopy (FESEM), micro-computed tomography, X-ray difraction and infrared spectroscopy to contextualize sequence data. This approach showed that the coralloid speleothems consist of banded siliceous stalactites composed of opal-A and hydrated halloysite. Analytical pyrolysis was also conducted to infer the possible origin of cave wall pigmentation, revealing that lignin degradation compounds can contribute to speleothem colour. Our RNA-based study showed for the frst time that members of the phylum Actinobacteria, with 55% of the clones belonging to Euzebyales order, were metabolically active components of yellow mats. In contrast, the DNA clone library revealed that around 45% of clones were afliated to Proteobacteria. Composition of microbial phyla obtained by NGS reinforced the DNA clone library data at the phylum level, in which Proteobacteria was the most abundant phylum followed by Actinobacteria. Microbial mats frequently coat extensive areas of walls and ceilings of karstic caves and lava tubes, usually devel- oping yellow, tan, orange, grey, pink and white-coloured bioflms1–6. -
Community Structure, Diversity, and Distribution Patterns of Sea Cucumber
Community structure, diversity, and distribution patterns of sea cucumber (Holothuroidea) in the coral reef area of Sapeken Islands, Sumenep Regency, Indonesia 1Abdulkadir Rahardjanto, 2Husamah, 2Samsun Hadi, 1Ainur Rofieq, 2Poncojari Wahyono 1 Biology Education, Postgraduate Directorate, Universitas Muhammadiyah Malang, Malang, East Java, Indonesia; 2 Biology Education, Faculty of Teacher Training and Education, Universitas Muhammadiyah Malang, Malang, Indonesia. Corresponding author: A. Rahardjanto, [email protected] Abstract. Sea cucumbers (Holothuroidea) are one of the high value marine products, with populations under very critical condition due to over exploitation. Data and information related to the condition of sea cucumber communities, especially in remote islands, like the Sapeken Islands, Sumenep Regency, East Java, Indonesia, is still very limited. This study aimed to determine the species, community structure (density, frequency, and important value index), species diversity index, and distribution patterns of sea cucumbers found in the reef area of Sapeken Islands, using a quantitative descriptive study. This research was conducted in low tide during the day using the quadratic transect method. Data was collected by making direct observations of the population under investigation. The results showed that sea cucumbers belonged to 11 species, from 2 orders: Aspidochirotida, with the species Holothuria hilla, Holothuria fuscopunctata, Holothuria impatiens, Holothuria leucospilota, Holothuria scabra, Stichopus horrens, Stichopus variegates, Actinopyga lecanora, and Actinopyga mauritiana and order Apodida, with the species Synapta maculata and Euapta godeffroyi. The density ranged from 0.162 to 1.37 ind m-2, and the relative density was between 0.035 and 0.292 ind m-2. The highest density was found for H. hilla and the lowest for S. -
High-Value Components and Bioactives from Sea Cucumbers for Functional Foods—A Review

Received: 3 August 2011; in revised form: 30 August 2011 / Accepted: 8 September 2011 / Published: 10 October 2011 Abstract: Sea cucumbers, belonging to the class Holothuroidea, are marine invertebrates, habitually found in the benthic areas and deep seas across the world. They have high commercial value coupled with increasing global production and trade. Sea cucumbers, informally named as bêche-de-mer, or gamat, have long been used for food and folk medicine in the communities of Asia and Middle East. Nutritionally, sea cucumbers have an impressive profile of valuable nutrients such as Vitamin A, Vitamin B1 (thiamine), Vitamin B2 (riboflavin), Vitamin B3 (niacin), and minerals, especially calcium, magnesium, iron and zinc. A number of unique biological and pharmacological activities including anti-angiogenic, anticancer, anticoagulant, anti-hypertension, anti-inflammatory, antimicrobial, antioxidant, antithrombotic, antitumor and wound healing have been ascribed to various species of sea cucumbers. Therapeutic properties and medicinal benefits of sea cucumbers can be linked to the presence of a wide array of bioactives especially triterpene glycosides (saponins), chondroitin sulfates, glycosaminoglycan (GAGs), sulfated polysaccharides, sterols (glycosides and sulfates), phenolics, cerberosides, lectins, peptides, glycoprotein, glycosphingolipids and essential fatty acids. -

Shelley, Australia, for R. Gabel US DI Washington, USA. RE: CITES: sea cucumbers for Appendix II – Reply to request for information Dear colleagues I shall first introduce myself as sea cucumber expert following numerous studies in the tropical Pacific and Indian oceans. I am the scientific editor of the Beche-de-Mer Information Bulletin published by the Secretariat of the Pacific Community (SPC), the only publication devoted to world sea cucumber issues (bi- ology, fisheries, markets). It can be found on the web at http://www.spc.int/coastfish. Recent studies have shown the worldwide overexploitation of most collected species. I believe it is the right time to draw international attention to these resources, but it is important to look in detail at which actions to undertake. I will give here a few personal opinions to help the discussion. The exploited sea cucumbers are only a few species among the 1200 presently described. Their taxonomy is very difficult and only a few specialists are still working and describing new species even among the ex- ploited ones (see Madagascar and Kenya…) (see references). As they are often considered in developed countries as ‘ugly or exotic’, the scientific studies are, therefore, not as advanced as for other marine resources and there is an urgent need for integrated studies. -

Rahimibashar Department of Marine Biology, Lahijan branch .Islamic Azad University Lahijan, Iran ABSTRACT As each new species evolved, the ossicles changed with it, so each species has uniquely shaped ossicles. Examination of gross morphology and microscopic ossicles showed that this species is Holothoria atra. Color uniformly black or dark brown; when alive body usually covered with sand coating of sand which may also serve to keep it cool by protecting it from the sun's rays. , except for several pairs bare patches dorsally; tables with reduced but sometimes spinose disc. The importance of detailed reproductive biological studies on Holothuria atra are necessary due to its important role in the conservation of the marine environment. This species found on subtidal sand and grassbed, 3to 4 m depth at Kish Island. Distributed throughout most of the tropical Indo-Pacific area. Holothoria atra, is a holothurian of order Aspidochirotes belonging to the family Holothuriidae genus Holothuria. It is deposit-feeder and is mainly found on sandy bottom of fringing reefs surrounding the Kish island. Holothoria atra, is a holothurian of order Aspidochirotes belonging to the family Holothuriidae genus Holothuria. Holothuria atra is an omnivore, sifting through the sediment with its tentacles and feeding on detritus and other organic matter. It ingests sand at the same time and digests the biofilm on the sand grains before ejecting them through its anus. -
