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. -
Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -
Sea Squirt Symbionts! Or What I Did on My Summer Vacation… Leah Blasiak 2011 Microbial Diversity Course
Sea Squirt Symbionts! Or what I did on my summer vacation… Leah Blasiak 2011 Microbial Diversity Course Abstract Microbial symbionts of tunicates (sea squirts) have been recognized for their capacity to produce novel bioactive compounds. However, little is known about most tunicate-associated microbial communities, even in the embryology model organism Ciona intestinalis. In this project I explored 3 local tunicate species (Ciona intestinalis, Molgula manhattensis, and Didemnum vexillum) to identify potential symbiotic bacteria. Tunicate-specific bacterial communities were observed for all three species and their tissue specific location was determined by CARD-FISH. Introduction Tunicates and other marine invertebrates are prolific sources of novel natural products for drug discovery (reviewed in Blunt, 2010). Many of these compounds are biosynthesized by a microbial symbiont of the animal, rather than produced by the animal itself (Schmidt, 2010). For example, the anti-cancer drug patellamide, originally isolated from the colonial ascidian Lissoclinum patella, is now known to be produced by an obligate cyanobacterial symbiont, Prochloron didemni (Schmidt, 2005). Research on such microbial symbionts has focused on their potential for overcoming the “supply problem.” Chemical synthesis of natural products is often challenging and expensive, and isolation of sufficient quantities of drug for clinical trials from wild sources may be impossible or environmentally costly. Culture of the microbial symbiont or heterologous expression of the biosynthetic genes offers a relatively economical solution. Although the microbial origin of many tunicate compounds is now well established, relatively little is known about the extent of such symbiotic associations in tunicates and their biological function. Tunicates (or sea squirts) present an interesting system in which to study bacterial/eukaryotic symbiosis as they are deep-branching members of the Phylum Chordata (Passamaneck, 2005 and Buchsbaum, 1948). -
How Do Seagrasses Face Herbivory? a Case of Study in Cadiz Bay
How do seagrasses face herbivory? A case of study in Cadiz bay Isabel Casal*1, Fernando G. Brun1 and Eva Zub´ıa2 *Corresponding author: [email protected] 1Department of Biology (Ecology Area), University of C´adiz,Puerto Real (C´adiz)Spain 2Department of Organic Chemistry, University of C´adiz,Puerto Real (C´adiz),Spain Keywords: Herbivory, Marine Angiosperms, Natural Products Introduction The marine angiosperms or seagrasses are vascular plants with leaves, rhizomes, roots, flowers and seeds that inhabit marine environment. Seagrasses are characterized by developing extensive crowded meadows in shallow coastal areas, forming one of the most important coastal habitats of the biosphere, bearing a great ecological value because of the services and functions they provide, both to humans and marine ecosystems. Seagrasses are distributed along all the coasts of the world, except in Antarctica (Robertson and Mann, 1984) while only four species are found in the Mediterranean Sea: Zostera noltei Hornemann (1832), Zostera marina Linnaeus (1753), Cymodocea nodosa Ascherson (1870) and Posidonia oceanica (Linnaeus) Delile (1813). With the exception of the P. oceanica, the other three species coexist in the Bay of Cadiz (Figure1, modified from Brun et al.(2015)). Figure 1: (A) Seagrass habitats in the Bay of Cadiz (B) Zostera noltei (C) Cymodocea nodosa (D) Zostera marina. 1 Marine angiosperms possess a secondary metabolism that synthetizes specific organic compounds known as natural products. These compounds play important roles in the survival of the plants, including their involvement in chemical defence mechanisms. One of the ecological functions played by these natural products could be their deterrent capacity against herbivores. -
WIDECAST Sea Turtle Recovery Action Plan for the Netherlands Antilles
CEP Technical Report: 11 1992 WIDECAST Sea Turtle Recovery Action Plan for the Netherlands Antilles PREFACE Sea turtle stocks are declining throughout most of the Wider Caribbean region; in some areas the trends are dramatic and are likely to be irreversible during our lifetimes. According to the IUCN Conservation Monitoring Centre's Red Data Book, persistent over-exploitation, especially of adult females on the nesting beach, and the widespread collection of eggs are largely responsible for the Endangered status of five sea turtle species occurring in the region and the Vulnerable status of a sixth. In addition to direct harvest, sea turtles are accidentally captured in active or abandoned fishing gear, resulting in death to tens of thousands of turtles annually. Coral reef and sea grass degradation, oil spills, chemical waste, persistent plastic and other marine debris, high density coastal development, and an increase in ocean-based tourism have damaged or eliminated nesting beaches and feeding grounds. Population declines are complicated by the fact that causal factors are not always entirely indigenous. Because sea turtles are among the most migratory of all Caribbean fauna, what appears as a decline in a local population may be a direct consequence of the activities of peoples many hundreds of kilometers distant. Thus, while local conservation is crucial, action is also called for at the regional level. In order to adequately protect migratory sea turtles and achieve the objectives of CEP's Regional Programme for Specially Protected Areas and Wildlife (SPAW), The Strategy for the Development of the Caribbean Environment Programme (1990-1995) calls for "the development of specific management plans for economically and ecologically important species", making particular reference to endangered, threatened, or vulnerable species of sea turtle. -

A Phase I Dose-Finding, Pharmacokinetics and Genotyping
www.nature.com/scientificreports OPEN A phase I dose‑fnding, pharmacokinetics and genotyping study of olaparib and lurbinectedin in patients with advanced solid tumors Andres Poveda1*, Ana Oaknin2, Ignacio Romero3, Angel Guerrero‑Zotano3, Lorena Fariñas‑Madrid2, Victor Rodriguez‑Freixinos4, Pedro Mallol5, Raquel Lopez‑Reig6,7 & Jose Antonio Lopez‑Guerrero6,7,8 The poly (ADP‑Ribose) polymerase (PARP) inhibitor olaparib has shown antitumor activity in patients with ovarian or breast cancer with or without BRCA1/2 mutations. Lurbinectedin is an ecteinascidin that generates DNA double‑strand breaks. We hypothesized that the combination of olaparib and lurbinectedin maximizes the DNA damage increasing the efcacy. A 3 + 3 dose‑escalation study examined olaparib tablets with lurbinectedin every 21 days. The purpose of this phase I study is to determine the dose‑limiting toxicities (DLTs) of the combination, to investigate the maximum tolerated dose (MTD), the recommended phase II dose (RP2D), efcacy, pharmacokinetics, in addition to genotyping and translational studies. In total, 20 patients with ovarian and endometrial cancers were included. The most common adverse events were asthenia, nausea, vomiting, constipation, abdominal pain, neutropenia, anemia. DLT grade 4 neutropenia was observed in two patients in dose level (DL) 5, DL4 was defned as the MTD, and the RP2D was lurbinectedin 1.5 mg/m2 + olaparib 250 mg twice a day (BID). Mutational analysis revealed a median of 2 mutations/case, 53% of patients with mutations in the homologous recombination (HR) pathway. None of the patients reached a complete or partial response; however, 60% of stable disease was achieved. In conclusion, olaparib in combination with lurbinectedin was well tolerated with a disease control rate of 60%. -
