The Dietary Preferences, Depth Range and Size of the Crown of Thorns Starfish (Acanthaster Spp.) on the Coral Reefs of Koh Tao, Thailand by Leon B
The dietary preferences, depth range and size of the Crown of Thorns Starfish (Acanthaster spp.) on the coral reefs of Koh Tao, Thailand By Leon B. Haines Author: Leon Haines 940205001 Supervisors: New Heaven Reef Conservation Program: Chad Scott Van Hall Larenstein University of Applied Sciences: Peter Hofman 29/09/2015 The dietary preferences, depth range and size of the Crown of Thorns Starfish (Acanthaster spp.) on the coral reefs of Koh Tao, Thailand Author: Leon Haines 940205001 Supervisors: New Heaven Reef Conservation Program: Chad Scott Van Hall Larenstein University of Applied Sciences: Peter Hofman 29/09/2015 Cover image:(NHRCP, 2015) 2 Preface This paper is written in light of my 3rd year project based internship of Integrated Coastal Zone management major marine biology at the Van Hall Larenstein University of applied science. My internship took place at the New Heaven Reef Conservation Program on the island of Koh Tao, Thailand. During my internship I performed a study on the corallivorous Crown of Thorns starfish, which is threatening the coral reefs of Koh Tao due to high density ‘outbreaks’. Understanding the biology of this threat is vital for developing effective conservation strategies to protect the vulnerable reefs on which the islands environment, community and economy rely. Very special thanks to Chad Scott, program director of the New Heaven Reef Conservation program, for supervising and helping me make this possible. Thanks to Devrim Zahir. Thanks to the New Heaven Reef Conservation team; Ploy, Pau, Rahul and Spencer. Thanks to my supervisor at Van Hall Larenstein; Peter Hofman. 3 Abstract Acanthaster is a specialized coral-feeder and feeds nearly solely, 90-95%, on sleractinia (reef building corals), preferably Acroporidae and Pocilloporidae families. -

Conclusions Glossary Bibliography Biographical Sketch Summary Chemical signaling is an important communication mechanism within and between species in the marine environment. Chemical cues are of particular importance in aquatic systems since visibility can be greatly impaired by sediment load and the attenuation ofUNESCO light at greater depths. The physical – EOLSSand chemical properties in the marine environment influence the way chemical signals are produced, transported and detected, and also determine the nature and success of ecological interactions. Marine animals have very well developed chemical senses and chemical signals can help animals to identify conspecificsSAMPLE and regulate social behavior. CHAPTERS Reproductive processes such as mate recognition and synchronization in gamete, or larval release, may be highly influenced by chemical signals especially in plants and invertebrates where hormonal signaling is not complex. The establishment and maintenance of symbiotic associations as well as homing behavior may require of chemical signaling although these processes are less understood. Chemical signals are also important in food recognition and ingestion by grazers, carnivores and scavengers, predator detection and avoidance, alarm responses and deterrence of feeding behavior. -

TOPIC 3 Classification 3.1 Overview Our planet contains an amazing variety of living things. Scientists classify these living things into groups on the basis of their similarities and differences. This seahorse is called a sea dragon. Is it like a horse or can it be classified as something else? 3.1.1 Think about Classification • How can you use a key to unlock the door to classification? • Why bother classifying living things? • Which animals have their skeletons on the outside? • I have scales and lungs and live on land. What am I? • In terms of biological classification, which class do you belong to? • What did prehistoric pelycosaurs use their sail-like fins for? • Which herb helps relieve constipation?

First Record and Impact of the Crown-Of-Thorns Starfish, Acanthaster Planci (Spinulosida: Acanthasteridae) on Corals of Malpelo Island, Colombian Pacific
First record and impact of the crown-of-thorns starfish, Acanthaster planci (Spinulosida: Acanthasteridae) on corals of Malpelo Island, Colombian Pacific Krupskaya Narváez1 & Fernando A. Zapata2 1. Fundación Malpelo y Otros Ecosistemas Marinos. Carrera 11 No. 87-51 Local 4, Bogotá D.C., Colombia; [email protected] 2. Departamento de Biología, Universidad del Valle, Apartado Aéreo 25360, Cali, Colombia; [email protected] Received 30-VIII-2009. Corrected 11-XI-2009. Accepted 18-XII-2009. Abstract: The crown-of-thorns starfish, Acanthaster planci, is a major coral predator widely distributed in the Indo-Pacific region, where population outbreaks have caused dramatic impacts on coral reefs. In the Tropical Eastern Pacific (TEP) A. planci occurs at low population densities; it has been significantly abundant only in Panama and Cocos Island. We have recently found two individuals of A. planci at Malpelo Island, a small oce- anic island with significant coral communities located off the Colombian Pacific coast. The recent discovery of A. planci at Malpelo is significant in light of recent reports of its increased frequency of observation at Cocos Island and occurrence at the Galapagos Islands. The individuals found at Malpelo have been repeatedly sighted since 2004, actively feeding on nine species of coral. Although densities of A. planci are low at Malpelo and other oceanic islands of the TEP, these islands may act as stepping stones for the colonization of other coral reef areas in the region. However, the low densities of A. planci suggest that it currently poses no threat to coral reefs in the TEP. Rev. -

Two of these species—A. planci Linnaeus, 1758, distributed in the North Indian Ocean, and A. mauritiensis de Loriol, 1885, distributed in the South Indian Ocean—have been already unequivocally named. In contrast, the Pacific COTS (proposed name: A. solaris (Schreber, 1795) and the COTS from the Red Sea (still to be named) require further taxonomic work. COI barcoding sequences and Barcode Identification Numbers (BINs) are available for all four COTS species in the global Barcode of Life Database (BOLD). -

Therefore, there is a focus toward new chemotherapeutic agents to be obtained from natural sources. This study was carried out to evaluate cytotoxic and apoptotic effects of the Acanthaster planci starfish extract compared to tamoxifen in human breast cancer MCF-7 cell line. The extract was obtained using phosphate buffered saline. MTS assay and Annexin V assay were performed to evaluate the cytotoxic effect and apoptotic effect, respectively. The extract was found to inhibit the growth of MCF-7 cells (IC 50 =15.6 µg/ml) and induced apoptosis (52.9% after 1 h treatment and 63.9% after 2 h treatment). -

diversity Review Known Predators of Crown-of-Thorns Starfish (Acanthaster spp.) and Their Role in Mitigating, If Not Preventing, Population Outbreaks Zara-Louise Cowan 1,*, Morgan Pratchett 1, Vanessa Messmer 1 and Scott Ling 2 1 ARC Centre of Excellence for Coral Reef Studies, James Cook University, Townsville, QLD 4811, Australia; [email protected] (M.P.); [email protected] (V.M.) 2 Institute for Marine and Antarctic Studies, University of Tasmania, Hobart, TAS 7001, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-7-4781-5747 Academic Editors: Sven Uthicke and Michael Wink Received: 20 November 2016; Accepted: 17 January 2017; Published: 22 January 2017 Abstract: Predatory release has long been considered a potential contributor to population outbreaks of crown-of-thorns starfish (CoTS; Acanthaster spp.). This has initiated extensive searches for potentially important predators that can consume large numbers of CoTS at high rates, which are also vulnerable to over-fishing or reef degradation. Herein, we review reported predators of CoTS and assess the potential for these organisms to exert significant mortality, and thereby prevent and/or moderate CoTS outbreaks. In all, 80 species of coral reef organisms (including fishes, and motile and sessile invertebrates) are reported to predate on CoTS gametes (three species), larvae (17 species), juveniles (15 species), adults (18 species) and/or opportunistically feed on injured (10 species) or moribund (42 species) individuals within reef habitats. It is clear however, that predation on early life-history stages has been understudied, and there are likely to be many more species of reef fishes and/or sessile invertebrates that readily consume CoTS gametes and/or larvae.
