Here we report, for the first time, molecular phylogenetic analyses using plastid rbcL gene sequences and morphological observations of P. scopulorum collected from the type locality, Rottnest Island in Western Australia. Mor- phological characteristics of the Rottnest Island specimens allowed unequivocal identification, however, the sequence analy- ses uncovered discrepancies in previous molecular studies that included specimens identified as P. scopulorum from other locations. The phylogenetic evidence clearly revealed that P. scopulorum from Rottnest Island formed a sister clade with P. caespitosa from Spain (JX828149 as P. scopulorum) with moderate support, but that it differed from specimens identified as P. scopulorum from the U.S.A. (AY396039, EU492915). In light of this, we suggest that P. scopulorum be considered an endemic species with a distribution restricted to Australia.

  • Investigating Diversity, Evolution, Development and Physiology of Red Algal Parasites from New Zealand
    Investigating diversity, evolution, development and physiology of red algal parasites from New Zealand BY MAREN PREUSS A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy Victoria University of Wellington Te Whare Wānanga o te Ūpoko o te Ika a Māui (2018) ii This thesis was conducted under the supervision of Associate Professor Joe Zuccarello (Primary Supervisor) Victoria University of Wellington, Wellington, New Zealand and Professor Wendy Nelson (Secondary Supervisor) National Institute of Atmospheric Research, Wellington, New Zealand and University of Auckland, Auckland, New Zealand iii iv Abstract Red algal parasites have evolved independently over a 100 times and grow only on other red algal hosts. Most parasites are closely related to their host based on the similarity of their reproductive structures. Secondary pit connections between red algal parasites and their hosts are used to transfer parasite organelles and nuclei into host cells. Morphological and physiological changes in infected host cells have been observed in some species. Parasite mitochondrial genomes are similar in size and gene content to free-living red algae whereas parasite plastids are highly reduced. Overall, red algal parasites are poorly studied and thus the aim of this study was to increase the general knowledge of parasitic taxa with respect to their diversity, evolutionary origin, development, physiology, and organelle evolution. Investigation of the primary literature showed that most species descriptions of red algal parasites were poor and did not meet the criteria for defining a parasitic relationship. This literature study also revealed a lack of knowledge of many key parasitic processes including early parasite development, host cell “control”, and parasite origin.

  • Inventory of Intertidal Habitats: Boston Harbor Islands, a National Park Area
    National Park Service U.S. Department of the Interior Northeast Region Natural Resource Stewardship and Science Inventory of Intertidal Habitats: Boston Harbor Islands, a national park area Richard Bell, Mark Chandler, Robert Buchsbaum, and Charles Roman Technical Report NPS/NERBOST/NRTR-2004/1 Photo credit: Pat Morss The Northeast Region of the National Park Service (NPS) is charged with preserving, protecting, and enhancing the natural resources and processes of national parks and related areas in 13 New England and Mid-Atlantic states. The diversity of parks and their resources are reflected in their designations as national parks, seashores, historic sites, recreation areas, military parks, memorials, and rivers and trails. Biological, physical, and social science research results, natural resource inventory and monitoring data, scientific literature reviews, bibliographies, and proceedings of technical workshops and conferences related to 80 of these park units in Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont are disseminated through the NPS/NERBOST Technical Report and Natural Resources Report series. The reports are numbered according to fiscal year and are produced in accordance with the Natural Resource Publication Management Handbook (1991). Documents in this series are not intended for use in open literature. Mention of trade names or commercial products does not constitute endorsement or recommendation for use by the National Park Service. Individual parks may also disseminate information through their own report series. Reports in these series are produced in limited quantities and, as long as the supply lasts, may be obtained by sending a request to the address on the back cover.

  • In the Tropical Western Atlantic: I. Colombia and Venezuela
    BULLETIN OF MARINE SCIENCE, 33(4): 881-898, 1983 GENUS POLYSIPHONIA (RHODOPHYTA, CERAMIALES) IN THE TROPICAL WESTERN ATLANTIC: I. COLOMBIA AND VENEZUELA Donald F. Kapraun, Andres J. Lemus and German Bula-Meyer ABSTRACT Keys, illustrations, and descriptions are provided for 10 species of Polysiphonia from the Caribbean coast of Colombia and Venezuela: p, atlantica. P. binneyi, P. denudata. p, east- woodae, P. Jerulacea, P. jlaccidissima, P. havanensis. p, howei, P. sphaerocarpa and P. sub- tilissima. Five of these species are newly reported for the study area. Comparisons are made with descriptions for these species elsewhere, and taxonomic and phytogeographic conclusions given. Twenty-two species of Polysiphonia. exclusive of cool temperate species which occur in the Carolinas and Bermuda, are known from the warm temperate and tropical waters of the western Atlantic (Taylor, 1960; 1976; Wynne and Edwards, 1970; Cordeiro-Marino and Oliveira F., 1970; Brauner, 1975; Oliveira F. and Ugadim, 1976; Kapraun, 1977b; 1979a; 1980a; Kapraun and Norris, 1982). De- spite the increased efforts of the past decade, there are still no published accounts of the taxonomically important morphological features for many of these species, including some of the most commonly reported. The present study of Polysiphonia from Colombia and Venezuela (part 1),along with a complementary investigation of this genus from other western Atlantic sites which will be published separately (part II), is intended to provide these details for both previously known and newly reported species in the western Atlantic. MATERIALS AND METHODS Polysiphonia material for this study was collected from a wide range of habitats in Venezuela (Fig.
