Population Genetics and Phylogeography of Hawaiian Coral Reef Echinoderms
ISLANDS, ARCHIPELAGOS, AND BEYOND: POPULATION GENETICS AND PHYLOGEOGRAPHY OF HAWAIIAN CORAL REEF ECHINODERMS A DISSERTATION SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI‘I AT MĀNOA IN PARTIAL FULFILLMENT OF THE REQUIREMENT FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN ZOOLOGY AUGUST 2012 By Derek J. 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. -

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. -

1 Conference of the Parties to The
Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES); Seventeenth Regular Meeting: Taxa Being Considered for Amendments to the CITES Appendices The United States, as a Party to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), may propose amendments to the CITES Appendices for consideration at meetings of the Conference of the Parties. The seventeenth regular meeting of the Conference of the Parties to CITES (CoP17) is scheduled to be held in South Africa, September 24 to October 5, 2016. With this notice, we describe proposed amendments to the CITES Appendices (species proposals) that the United States might submit for consideration at CoP17 and invite your comments and information on these proposals. Please note that we published an abbreviated version of this notice in the Federal Register on August 26, 2015, in which we simply listed each species proposal that the United States is considering for CoP17, but we did not describe each proposal in detail or explain the rationale for the tentative U.S. position on each species. CITES is an international treaty designed to control and regulate international trade in certain animal and plant species that are affected by trade and are now, or potentially may become, threatened with extinction. These species are listed in the Appendices to CITES, which are available on the CITES Secretariat’s website at http://www.cites.org/sites/default/files/eng/app/2015/E-Appendices-2015-02-05.pdf. Currently, 181 Parties, including the United States, have joined CITES. -

The genes involved in the various biosynthetic pathways are unknown. To gain insight into these pathways in an echinoderm, we performed a comparative transcriptome analysis and functional annotation of the body wall and the radial nerve of the sea cucumber Holothuria scabra; to define genes associated with body wall metabolic functioning and secondary metabolite biosynthesis. -
