The Red Alga Polysiphonia (Rhodomelaceae) in the Northern Gulf of California
The Red Alga Polysiphonia (Rhodomelaceae) in the Northern Gulf of California GEORGE J. HOLLENBERG ' • ,. • •a and JAMES N. NORRIS SMITHSONIAN CONTRIBUTIONS TO THE MARINE SCIENCES SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world cf science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. -
RED ALGAE · RHODOPHYTA Rhodophyta Are Cosmopolitan, Found from the Artic to the Tropics
RED ALGAE · RHODOPHYTA Rhodophyta are cosmopolitan, found from the artic to the tropics. Although they grow in both marine and fresh water, 98% of the 6,500 species of red algae are marine. Most of these species occur in the tropics and sub-tropics, though the greatest number of species is temperate. Along the California coast, the species of red algae far outnumber the species of green and brown algae. In temperate regions such as California, red algae are common in the intertidal zone. In the tropics, however, they are mostly subtidal, growing as epiphytes on seagrasses, within the crevices of rock and coral reefs, or occasionally on dead coral or sand. In some tropical waters, red algae can be found as deep as 200 meters. Because of their unique accessory pigments (phycobiliproteins), the red algae are able to harvest the blue light that reaches deeper waters. Red algae are important economically in many parts of the world. For example, in Japan, the cultivation of Pyropia is a multibillion-dollar industry, used for nori and other algal products. Rhodophyta also provide valuable “gums” or colloidal agents for industrial and food applications. Two extremely important phycocolloids are agar (and the derivative agarose) and carrageenan. The Rhodophyta are the only algae which have “pit plugs” between cells in multicellular thalli. Though their true function is debated, pit plugs are thought to provide stability to the thallus. Also, the red algae are unique in that they have no flagellated stages, which enhance reproduction in other algae. Instead, red algae has a complex life cycle, with three distinct stages. -

It is abundantly found throughout the world in cold waters. A few species occur in fresh waters. The plant grows attached to rocks and stones along coasts. Some species are epiphytes on other algae like members of Fucales and Laminaria. Ectocarpus fasciculatus grows on the fins of certain fish (epizoic) in Sweden. Ectecarpus dermonemcnis is endophytic. Ectocarpus carver and Ectocarpus spongiosus are free- floating. Indian spp. E. filife E. enhali E. coniger E. rhodochortonoides Plant Body • Genetically the thalli may be haploid or diploid. But both the types are morphologically alike. The thallus consists of profusely branched uniseriate filaments. It shows heterotrichous habit. There are two systems of filaments. These are prostrate and projecting system. The filaments of the projecting system arise from the filaments of prostrate system • a) Prostate system: The prostrate system consists of creeping, leptate, irregularly branched filaments. These filaments are attached to the substratum with the help of rhizoids. This system enters the host tissues in epiphytic conditions. Prostrate system is poorly developed in free floating species. • b) Projecting system: The projecting system arises from the prostrate system. It consists of well branched filaments. Each branch arises beneath the septa. The main axis and the branches of the projecting system are uniseriate. In this case, rans are Joined end to end in a single series. -

Corresponding author: Gabriela García-Soto, [email protected] Abstract We record Acanthophora dendroides Harvey for the first time in the Atlantic Ocean. Two specimens from the Philip- pines were resolved as conspecific to the Atlantic A. dendroides in molecular analyses extending its geographic range to the Philippines. In light of new evidence provided by field-collected specimens ofAcanthophora spicifera (M.Vahl) Børgesen (generitype) from Florida and Venezuela, the flattened species A. pacifica(Setchell) Kraft, showed no affin- ity to Acanthophora sensu stricto, suggesting that the genus should be restricted to cylindrical species only.

This study provides a comprehensive characterization of the chemical composition of 15 Arctic red algal species from the perspective of their practical relevance in medicine and the food industry. We show that several virtually unstudied species may be regarded as promis- ing sources of different valuable metabolites and minerals. Thus, several filamentous ceramialean algae (Ceramium virgatum, Polysiphonia stricta, Savoiea arctica) had total protein content of 20–32% of dry weight, which is comparable to or higher than that of already commercially exploited species Citation: Yanshin, N.; Kushnareva, (Palmaria palmata, Porphyra sp.).

Silva Festschrift Marine Algal (Seaweed) Collections at the Natural History Museum, London (BM): Past, Present and Future Ian Tittley Department of Botany, The Natural History Museum, London SW7 5BD ABSTRACT The specimen collections and libraries of the Natural History Museum (BM) constitute an important reference centre for macro marine algae (brown, green and red generally known as seaweeds). The first collections of algae were made in the sixteenth and seventeenth centuries and are among the earliest collections in the museum from Britain and abroad. Many collectors have contributed directly or indirectly to the development and growth of the seaweed collection and these are listed in an appendix to this paper. The taxonomic and geographical range of the collection is broad and a significant amount of information is associated with it. As access to this information is not always straightforward, a start has been made to improve this through specimen databases and image collections. A collection review has improved the availability of geographical information; lists of countries for a given species and lists of species for a given country will soon be available, while for Great Britain and Ireland geographical data from specimens have been collated to create species distribution maps. This paper considers issues affecting future development of the seaweed collection at the Natural History Museum, the importance and potential of the UK collection as a resource of national biodiversity information, and participation in a global network of collections. -

Notes on Ceramium (Rhodophyta: Ceramiales) from the Hawaiian Islands!
Pacific Science (1995), vol. 49, no. 2: 165-174 © 1995 by University of Hawai'i Press. All rights reserved Notes on Ceramium (Rhodophyta: Ceramiales) from the Hawaiian Islands! ISABEL MENESES 2 ABSTRACT: Ceramium is widely distributed and recorded from the coasts of the North Pacific Ocean. Thus, it is not surprising to find new species and new records of this genus among the numerous islands spread in this oceanic region. Extensive examination ofmaterial collected around O'ahu and other Hawaiian Islands has yielded two new records: Ceramium aduncum Nakamura (pre viously known from Japan), Ceramium clarionensis Setchell & Gardner (pre viously recorded for the Pacific coast of Mexico), and a new species, Ceramium cingulum Meneses. APPROXIMATELY 55 SPECIES of the genus Cer the island of O'ahu, Hawai'i, appearing in amium (Ceramiaceae) have been reported almost any collection made, mainly as epi for the tropical and subtropical North phytes. Recently, four new species were re Pacific Ocean, representing about one-half of corded (Norris and Abbott 1992). The goal the known species worldwide. Detailed de of the study reported here was to include all scriptions as well as passing references in possible morphological variations in the marine floras of this region describe species Ceramium taxa collected. Thus, intensive mainly from the Pacific coast of North and collections were made around O'ahu, and Central America (Setchell and Gardner 1924, collections from other Hawaiian Islands were 1930, 1937, Dawson 1944, 1945a,b, 1954a,b,c, examined. As a result three new records and 1957b, 1961, 1962, Hollenberg 1948) and one new species of Ceramium are reported.
