  • 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).

  • South Carolina Department of Natural Resources
    FOREWORD Abundant fish and wildlife, unbroken coastal vistas, miles of scenic rivers, swamps and mountains open to exploration, and well-tended forests and fields…these resources enhance the quality of life that makes South Carolina a place people want to call home. We know our state’s natural resources are a primary reason that individuals and businesses choose to locate here. They are drawn to the high quality natural resources that South Carolinians love and appreciate. The quality of our state’s natural resources is no accident. It is the result of hard work and sound stewardship on the part of many citizens and agencies. The 20th century brought many changes to South Carolina; some of these changes had devastating results to the land. However, people rose to the challenge of restoring our resources. Over the past several decades, deer, wood duck and wild turkey populations have been restored, striped bass populations have recovered, the bald eagle has returned and more than half a million acres of wildlife habitat has been conserved. We in South Carolina are particularly proud of our accomplishments as we prepare to celebrate, in 2006, the 100th anniversary of game and fish law enforcement and management by the state of South Carolina. Since its inception, the South Carolina Department of Natural Resources (SCDNR) has undergone several reorganizations and name changes; however, more has changed in this state than the department’s name. According to the US Census Bureau, the South Carolina’s population has almost doubled since 1950 and the majority of our citizens now live in urban areas.

Permanently submerged mangrove roots (Rhizophora mangle) are the main habitat of the ascidian Ecteinascidia turbinata in Cuba. It was occasionally found on black coral (Antiphates caribeana) between 22 and 38 meters deep. This species exhibits a wide distribution in all the mangrove keys surrounding the Island of Cuba but does not occur in riparian or fringing mangroves. Populations of this species are abundant in Cuba: in 75 % of the 58 localities sampled the species was present and in 57 % more than 50 % of the roots held at least one colony. The highest colony densities were found in the northern coast of Pinar del Río province with values near one colony per lineal meter of mangrove root. We found the highest density (1.46 col/m) and greatest biomass at Jutías Key, with values between 25 and 660 g/m. The average of wet biomass in the studied mangroves was 73.63 g/m. Rev. Biol.

    BULLETIN OF MARINE SCIENCE, 65(3): 755–760, 1999 RECOVERY OF ECTEINASCIDIA TURBINATA HERMAN 1880 (ASCIDIACEA: PEROPHORIDAE) POPULATIONS AFTER DIFFERENT LEVELS OF HARVESTING ON A SUSTAINABLE BASIS J. L. Carballo, A. Hernández-Zanuy, S. Naranjo, B. Kukurtzü and Alida García Cagide ABSTRACT The harvesting of Ecteinascidia turbinata on a sustainable basis could be an example for the production of metabolites from marine organisms while protecting natural popu- lations. A research program was carried out in order to determine the recovery capacity of an E. turbinata population, after carrying out harvesting experiments in the Carribbean and Mediterranean Sea. In the Mediterranean, 25, 40 and 100% of the population was collected, with two collections for each group at 45 and 60 d. There was complete recov- ery of the biomass in the 25 and 40% collections after 45 d, but in the 100% collections only 62% of the biomass had recovered after 60 d. In the Caribbean, 25, 50, 75%, and later 100%, collections were carried out. After 16 d there was a recovery of the density of the population but not of the biomass. After 3 mo there was a recovery of density, biom- ass and root coverage in the 100% collection. Natural substances obtained from marine invertebrates are currently one of the main sources of new medication against illnesses such as cancer. For a few years research has been carried out on a substance produced by the colonial tunicate Ecteinascidia turbinata Herdman, 1880, which shows activity against various types of solid tumors (Rinehart et al., 1990; Wright et al., 1990).

  • Chordate Ancestry of the Neural Crest: New Insights from Ascidians William R
    Seminars in Cell & Developmental Biology 18 (2007) 481–491 Review Chordate ancestry of the neural crest: New insights from ascidians William R. Jeffery ∗ Department of Biology, University of Maryland, College Park, MD 20742, USA Available online 19 April 2007 Abstract This article reviews new insights from ascidians on the ancestry of vertebrate neural crest (NC) cells. Ascidians have neural crest-like cells (NCLC), which migrate from the dorsal midline, express some of the typical NC markers, and develop into body pigment cells. These characters suggest that primordial NC cells were already present in the common ancestor of the vertebrates and urochordates, which have been recently inferred as sister groups. The primitive role of NCLC may have been in pigment cell dispersal and development. Later, additional functions may have appeared in the vertebrate lineage, resulting in the evolution of definitive NC cells. © 2007 Elsevier Ltd. All rights reserved.

  • The Tropical Western Atlantic Perophoridae Ascidiacea Ii. the Genus Ecteinascidia
    BULLETIN OF MARINE SCIENCE, 79(1): 49–70, 2006 THE TROPICAL WESTERN ATLANTIC PEROPHORIDAE ASCIDIACEA II. THE GENUS ECTEINASCIDIA Ivan Goodbody and Linda Cole ABSTRACT Four species of Ecteinascidia occur in the tropical western Atlantic. The char- acteristics of each species are described and their distribution reviewed. Many characteristics are related to zooid size, although others are independent of size. Three species are common and widespread but the fourth,Ecteinascidia conklini Berrill, 1932, is rare and until recently there have been few records of its distribu- tion. Ecteinascidia minuta (Berrill, 1932) is closely related to Ecteinascidia herd- mani Medioni, 1969 from the Mediterranean and further research may show that the two are synonymous. The general characteristics of the family Perophoridae and its two component gen- era Perophora Wiegmann, 1835 and Ecteinascidia Herdman, 1880 were discussed in an earlier paper (Goodbody, 1994). The distinction between the two genera is based primarily on the number of rows of stigmata in the branchial sac, the organization of the alimentary canal, and the form of the testis (Kott, 1985). Most Perophora spe- cies have only four or five rows of stigmata while Ecteinascidia always has more than eight and usually between 12 and 20. In Perophora the gut loop is horizontal and the rectum short, while in Ecteinascidia the gut loop is more open with a long rectum. In both genera the gonads are situated in the gut loop; in Perophora the testis usually has only one or a few testis lobes, while in Ecteinascidia there are many pyriform testis lobes, often arranged in a crescent.
