Because of the ubiquity ofthese symbioses as well as the derived biomedical applications, the study ofboth beneficial and pathogenic host-microbe associations has long been established. The monospecific light organ association between the Hawaiian sepiolid squid Euprymrw se%pes and the marine luminous bacterium Vibrio fiseheri has been used as a experimental model for the study ofthe most common type ofanimal-bacterial interaction, i.e., the association ofcoevolved Gram-negative bacteria with the extracellular apical surfaces ofpolarized epithelia. A fundamental step for understanding the mechanisms ofhost-symbiont associations lies in defining the genetic components involved; specifically defining changes in host gene expression. The studies presented in this dissertation identify and characterize V. fiseheri-induced changes in host gene expression at both the transcript and protein level. iii TABLE OF CONTENTS Abstract. ...................................... ..........................................

    Taxonomy and diversity of the sponge fauna from Walters Shoal, a shallow seamount in the Western Indian Ocean region By Robyn Pauline Payne A thesis submitted in partial fulfilment of the requirements for the degree of Magister Scientiae in the Department of Biodiversity and Conservation Biology, University of the Western Cape.

Opinions expressed and conclusions arrived at, are those of the author and are not necessarily to be attributed to the NRF. December 2015 Taxonomy and diversity of the sponge fauna from Walters Shoal, a shallow seamount in the Western Indian Ocean region Robyn Pauline Payne Keywords Indian Ocean Seamount Walters Shoal Sponges Taxonomy Systematics Diversity Biogeography ii Abstract Taxonomy and diversity of the sponge fauna from Walters Shoal, a shallow seamount in the Western Indian Ocean region R. 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.

  • Early Stages of Fishes in the Western North Atlantic Ocean Volume
    ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation.

Sponge secondary metabolites are sought-after for their potential in pharmaceutical applications, and in the past, they were also used as taxonomic markers alongside the difficult and homoplasy-prone sponge morphology for species delineation (chemotaxonomy). The understanding Citation: Galitz, A.; Nakao, Y.; of phylogenetic distribution and distinctiveness of metabolites to sponge lineages is pivotal to reveal Schupp, P.J.; Wörheide, G.; pathways and evolution of compound production in sponges.
