Diversity and Phylogeography of Southern Ocean Sea Stars (Asteroidea)
Diversity and phylogeography of Southern Ocean sea stars (Asteroidea) Thesis submitted by Camille MOREAU in fulfilment of the requirements of the PhD Degree in science (ULB - “Docteur en Science”) and in life science (UBFC – “Docteur en Science de la vie”) Academic year 2018-2019 Supervisors: Professor Bruno Danis (Université Libre de Bruxelles) Laboratoire de Biologie Marine And Dr. Thomas Saucède (Université Bourgogne Franche-Comté) Biogéosciences 1 Diversity and phylogeography of Southern Ocean sea stars (Asteroidea) Camille MOREAU Thesis committee: Mr. Mardulyn Patrick Professeur, ULB Président Mr. Van De Putte Anton Professeur Associé, IRSNB Rapporteur Mr. Poulin Elie Professeur, Université du Chili Rapporteur Mr. Rigaud Thierry Directeur de Recherche, UBFC Examinateur Mr. Saucède Thomas Maître de Conférences, UBFC Directeur de thèse Mr. Danis Bruno Professeur, ULB Co-directeur de thèse 2 Avant-propos Ce doctorat s’inscrit dans le cadre d’une cotutelle entre les universités de Dijon et Bruxelles et m’aura ainsi permis d’élargir mon réseau au sein de la communauté scientifique tout en étendant mes horizons scientifiques. C’est tout d’abord grâce au programme vERSO (Ecosystem Responses to global change : a multiscale approach in the Southern Ocean) que ce travail a été possible, mais aussi grâce aux collaborations construites avant et pendant ce travail. Cette thèse a aussi été l’occasion de continuer à aller travailler sur le terrain des hautes latitudes à plusieurs reprises pour collecter les échantillons et rencontrer de nouveaux collègues. Par le biais de ces trois missions de recherches et des nombreuses conférences auxquelles j’ai activement participé à travers le monde, j’ai beaucoup appris, tant scientifiquement qu’humainement. -

Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -

The Advantages of the Pentameral Symmetry of the Starfish
The advantages of the pentameral symmetry of the starfish Liang Wua1, Chengcheng Jia1, Sishuo Wanga, and Jianhao Lvb a College of Biological Sciences, China Agricultural University, Beijing, 100094, China b College of Science, China Agricultural University, Beijing, 100094, China 1 Joint first authors. Corresponding author Liang Wu College of Biological Sciences, China Agricultural University, Beijing, 100094, China Tel: +86-10-62731071/+86-13581827546 Fax: +86-10-62731332 E-mail: [email protected] Chengcheng Ji E-mail: [email protected] Sishuo Wang E-mail: [email protected] Jianhao Lv E-mail: [email protected] Abstract Starfish typically show pentameral symmetry, and they are typically similar in shape to a pentagram. Although starfish can evolve and live with other numbers of arms, the dominant species always show pentameral symmetry. We used mathematical and physical methods to analyze the superiority of starfish with five arms in comparison with those with a different number of arms with respect to detection, turning over, autotomy and adherence. In this study, we determined that starfish with five arms, although slightly inferior to others in one or two aspects, exhibit the best performance when the four aforementioned factors are considered together. In addition, five-armed starfish perform best on autotomy, which is crucially important for starfish survival. This superiority contributes to the dominance of five-armed starfish in evolution, which is consistent with the practical situation. Nevertheless, we can see some flexibility in the number and conformation of arms. The analyses performed in our research will be of great help in unraveling the mysteries of dominant shapes and structures. -
Biostratigraphy and Diversity Patterns of Cenozoic Echinoderms from Florida
BIOSTRATIGRAPHY AND DIVERSITY PATTERNS OF CENOZOIC ECHINODERMS FROM FLORIDA By CRAIG W. OYEN A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2001 Walter and Norma Oyen, who have always I dedicate this to my parents, expressed absolute confidence in my ability to succeed and supported all my this without their endeavors without question or hesitation. I could not have done it realize. support through all these years and I appreciate more than they ACKNOWLEDGMENTS This project could not have been completed without the aid of many people. Most important is the assistance and direction given by my dissertation committee chair, Dr. Douglas S. Jones. He encouraged me to work on whatever suggestions to improve my topic(s) I found interesting, and simply gave me approach in order to answer any of those questions. He also made my time in Gainesville enjoyable academically and socially by introducing me to other faculty and students, inviting me to his home or restaurants for dinners, and participating in pick-up basketball games and intramural games for relaxation. He (along with Roger Portell) accompanied me on many fascinating fieldtrips in Florida and other locations (often in association with GSA meetings) that expanded my scientific and other perspectives greatly. I thank the other members of my dissertation committee, Drs. Randazzo, Hodell, MacFadden, and Mature, for participating in my research and providing guidance whenever I it to had this group of faculty asked for their help. I consider a pleasure have members participating on my committee because they only treated me with respect and they openly provided suggestions they believed would serve me best in the context of completing my research and degree. -

The seastar will eat a wide range of prey and has the potential for ecological and economic harm in its introduced range. Because the seastar is well established and abundantly widespread, eradication is almost impossible. However, prevention and control measures are being implemented to stop the species from establishing in new waters. view this species on IUCN Red List Global Invasive Species Database (GISD) 2021.

(Eds.) Echinoderm Research 2010: Proceedings of the Seventh European Conference on Echinoderms, Göttingen, Germany, 2–9 October 2010. Zoosymposia, 7, xii + 316 pp. Abstract In species of the family Heliasteridae, the ossicles of the proximal parts of the sides of each ray are joined by connective tissue to those of the adjacent rays to form interradial septa. These provide support to the extensive disc. Only a relatively small part of the ray is free. Autotomy of rays occurs in Heliaster helianthus in response to predatory attack by the asteroid Meyenaster gelatinosus. Autotomy of the ray does not occur at the base of the free part of the ray (arm) but near the base of the ray. In addition to the plane of autotomy at this location, a longitudinal plane of autotomy occurs in the connec- tive tissue between the ossicles of the interradial septa. This indicates a plane of mutable collagenous tissue is present. Autotomy of the ray involves all these planes of autotomy and results in loss of most of the ray. Key words: Asteroidea, Heliasteridae, autotomy, ray loss, mutable collagenous tissue Introduction Autotomy of rays occurs near the base of the arm (the free part of the ray) in most asteroids (Emson & Wilkie 1980). -
