  • Marine Algae of French Frigate Shoals, Northwestern Hawaiian Islands: Species List and Biogeographic Comparisons1
    Marine Algae of French Frigate Shoals, Northwestern Hawaiian Islands: Species List and Biogeographic Comparisons1 Peter S. Vroom,2 Kimberly N. Page,2,3 Kimberly A. Peyton,3 and J. Kanekoa Kukea-Shultz3 Abstract: French Frigate Shoals represents a relatively unpolluted tropical Pa- cific atoll system with algal assemblages minimally impacted by anthropogenic activities. This study qualitatively assessed algal assemblages at 57 sites, thereby increasing the number of algal species known from French Frigate Shoals by over 380% with 132 new records reported, four being species new to the Ha- waiian Archipelago, Bryopsis indica, Gracilaria millardetii, Halimeda distorta, and an unidentified species of Laurencia. Cheney ratios reveal a truly tropical flora, despite the subtropical latitudes spanned by the atoll system. Multidimensional scaling showed that the flora of French Frigate Shoals exhibits strong similar- ities to that of the main Hawaiian Islands and has less commonality with that of most other Pacific island groups.

Accepted 14 January, 2010 Vegetative propagation from thallus segments and protoplasts of the gametophyte of Bryopsis hypnoides Lamouroux (Chlorophyta, Bryopsidales) was studied in laboratory cultures. Thallus segments were cultured at 20°C, 20 µmol photons m -2 s-1, 12:12 h LD); protoplasts were cultured under various conditions, viz. 15°C, 15 µmol photons m -2 s-1, 10:14 h LD; 20°C, 20 µmol photons m -2 s-1, 12:12 h LD; and 25°C, 25 µmol photons m -2 s-1, 14:10 h LD. Microscope observation revealed that the protoplast used for regeneration was only part of the protoplasm and the regeneration process was complete in 12 h. The survival rate of the segments was 100% and the survival rate of protoplasts was around 15%, regardless of culture conditions. Protoplasts were very stable in culture and were tolerant of unfavorable conditions. Cysts developed at the distal end or middle portion of gametophytic filaments under low illumination (2 - 5 µmol photons m -2 s-1), the key induction factor.

The order is composed of three suborders – Ostreobineae, Bryopsidineae, and Seaweeds Halimedineae. While previous studies improved the higher-level classification of the order, the taxonomic Chloroplast genome placement of some genera in Bryopsidineae (Pseudobryopsis and Lambia) as well as the relationships between the Phylogeny families of Halimedineae remains uncertain. In this study, we re-assess the phylogeny of the order with datasets Ulvophyceae derived from chloroplast genomes, drastically increasing the taxon sampling by sequencing 32 new chloroplast genomes. The phylogenies presented here provided good support for the major lineages (suborders and most families) in Bryopsidales. In Bryopsidineae, Pseudobryopsis hainanensis was inferred as a distinct lineage from the three established families allowing us to establish the family Pseudobryopsidaceae. The Antarctic species Lambia antarctica was shown to be an early-branching lineage in the family Bryopsidaceae.

Smithsonian Contributions to the Marine Sciences, number 29, 38 pages, 1 figure, 1987.—Records of the benthic marine algae of the Island of Taiwan and neighboring islands have been organized in a floristic listing. All publications with citations of benthic marine green algae (Chlorophyta), brown algae (Phaeophyta), and red algae (Rhodophyta) in Taiwan are systematically ar­ ranged under the currently accepted nomenclature for each species. The annotated list includes names of almost 600 taxa, of which 476 are recognized today. In comparing the three major groups, the red algae predominate with 55% of the reported species, the green algae comprise 24%, and the browns 21%. Laurencia brongniartii}. Agardh is herein reported for Taiwan for the first time. The history of modern marine phycology in the Taiwan region is reviewed. Three periods of phycological research are recognized: the western (1866-1905); Japanese (1895-1945); and Chinese (1950-present). Western phycologists have apparently overlooked the large body of Japanese studies, which included references and records of Taiwan algae. By bringing together in one place all previous records of the Taiwanese marine flora, it is our expectation that this work will serve as a basis for further phycological investigations in the western Pacific region.

GARGIULO , AND GIUSI GENOVESE (Communication presented by Prof. Giacomo Tripodi) ABSTRACT. The genus Bryopsis comprises siphonous green algae widely distributed from tropical to polar seas. Despite the early reports on the simplicity of its life history, subse- quent culture observations showed variety of life history patterns, even within a single species. Karyological data and reports on DNA quantification led to somewhat contradic- tory conclusions about the ploidy level of the two life history phases and about the moment of meiosis. Long term observations on Mediterranean species highlighted new alternatives in recycling of the two morphological phases. Looking at all published experimental data, we summarize all life history pathways of Bryopsis species. 1. Introduction The genus Bryopsis J.V. Lamouroux [1] comprises green algae consisting of tubular multinucleate (siphonous) axes, lacking cross walls, variously branched with a feather-like appearance. Species are widely distributed from tropical to polar seas. Despite the early reports on the simplicity of its life history [2, 3], subsequent culture observations showed a more complex cycle [4-9]. A discovery of variety of life history patterns, even within a single species, and of new reproductive characters [7, 8, 10] led to the establishment of new genera: Pseudobryopsis Berthold in Oltmanns [11], a Bryopsis-looking alga differing because of peculiar pyriform gametangia, and Bryopsidella J.

Resumen Se describe Pseudoderbesia como genera nuevo dentro de las Bryopsidaceae. Se aislaron cuatro clones de Pseudoderbesia y se mantuvieron como cultivos unialgales: dos provenientes de la Costa Colombiana del Caribe (P. arbuscula) y dos de las Islas Canarias en el Oceano Atlantica (Pseudoderbesia sp.). Aunque se conoce solo la lase gametolftica, hay razones suficientes para el establecimiento de un nuevo genera. Se describe y discute el crecimiento, variabilidad, producci6n bajo condiciones de cultivo. Se sugiere la posibilidad que ciertas especies de Oerbesia que poseen ramitlcaclon dicotornica y filamentos gradual mente atenuados, como O. fastigiata, O. attenuata y O. padinae, sean real mente miembros de Pseudoderbesia. Abstract Pseudoderbesia is described as a new genus within the Bryopsidaceae. Four clones of Pseudoderbesia were isolated and kept as unialgal cultures: two from the Caribbean coast of Colombia (P. arbuscula) and two from the Canary Islands, Atlantic Ocean (Pseudoderbesia sp.). Although only the gametophylic phase is known, it is distinct enough forthe establishement of a new genus. Growth, variability and swarmer production, under culture conditions, are described and discussed. It is suggested, that some little known species of Oerbesia with dichotomous branching and gradually attenuated filaments, like O. fast/giata, O. attenuata and O. padinae, could actually be members of Pseudoderbesia.

The wider Caribbean is facing rapid changes associated with anthropogenic activities of coastal alteration, pollution loading and weather patterns, with losses of biodiversity expected. Submerged Aquatic Vegetation (SAV) is a key component of marine communities adding both structural complexity and species diversity to the wider Caribbean. This study aimed to examine SAV species assemblages and their extent at a unique coastal ecosystem in the Southern Caribbean Sea. This ecosystem remains unexplored for its nearshore marine biodiversity due to its remoteness and harsh environmental conditions. The study took place at ten survey sites in shallow nearshore waters of northeastern La Guajira peninsula of Colombia.

    Micronesica 35-36:54-99. 2003 Revised checklist of benthic marine macroalgae and seagrasses of Guam and Micronesia. CHRISTOPHER S. LOBBAN Division of Natural Sciences University of Guam Mangilao, GU 96923 ROY T. TSUDA Marine Laboratory University of Guam, Mangilao, GU 96923 Abstract— We have compiled the new records and nomenclatural changes since Tsuda & Wray’s 1977 checklist and Tsuda’s 1981a addendum. There are now 653 species of benthic marine algae reported from Micronesia: 85 species of Cyanophyta, 324 Rhodophyta, 58 Heterokontophyta (including 54 Phaeophyceae), and 186 Chlorophyta. We document here 40 new records for Guam. The total for Guam is now 237 species: 26 Cyanophyta, 109 Rhodophyta, 31 Heterokontophyta (including 27 Phaeophyceae), and 71 Chlorophyta. We have included 3 Pelagophyceae and 1 Bacillariophyceae (diatom) that form macroscopic colonies, as well as the 10 species of seagrasses (Magnoliophyta) that occur in the region. Introduction There has been a modest amount of phycological activity in Micronesia in the decades since Tsuda & Wray (1977) published a checklist of seaweeds that had been reported from the islands in the region. Some additions to the list were published by Tsuda (1981a). Tsuda (1981b) also printed a checklist for Guam, which included a number of species not included in either of his other checklists. Recent work in Pohnpei by Hodgson & McDermid (2000) and McDermid et al. (2002) added many new records, particularly of subtidal Rhodophyta. We document here 40 new records from Guam, including those from technical reports by Tsuda (1981b, 1992, 1993), 22 of which are new for Micronesia. Additionally, there has been much phycological work, chiefly outside the region, that improves our understanding of the species and their systematic positions.
