    Common Benthic Algae and Cyanobacteria in Southern California Tidal Wetlands

    Scripps Institution of Oceanography Technical Report Common benthic algae and cyanobacteria in southern California tidal wetlands Christopher N. Janousek Scripps Institution of Oceanography, University of California, San Diego 11 July 2011 Janousek 2011: Algae and cyanobacteria of southern California marine wetlands. 1 Abstract Benthic algae and photosynthetic bacteria are important components of coastal wetlands, contributing to primary productivity, nutrient cycling, and other ecosystem functions. Despite their key roles in mudflat and salt marsh food webs, the extent and patterns of diversity of these organisms is poorly known. Sediments from intertidal marshes in San Diego County, California host a variety of cyanobacteria, diatoms, and multi-cellular algae. This flora describes approximately 40 taxa of common and notable cyanobacteria, microalgae and macroalgae observed in wetland sediments, principally from a small tidal marsh in Mission Bay. Cyanobacteria included coccoid and heterocyte and non-heterocyte bearing filamentous genera. A phylogenetically-diverse assemblage of pennate and centric diatoms, euglenoids, green algae, red algae, tribophytes and brown seaweeds was also observed. Most taxa are illustrated with photographs. Key words alpha diversity • cyanobacteria • diatoms • euglenoids • Kendall-Frost Mission Bay Marsh Reserve • macroalgae • microphytobenthos • salt marsh • Tijuana Estuary • Vaucheria Introduction The sediments of coastal marine wetlands in California are inhabited by a variety of algal and bacterial primary producers in addition to the more conspicuous vascular plants that provide most of the physical structure of coastal salt marshes and seagrass meadows. The non-vascular plant flora includes microscopic cyanobacteria, anoxygenic phototrophic bacteria, diatoms, and euglenoids, often collectively known as “microphytobenthos” (Sullivan and Currin 2000). Larger green algae, red and brown seaweeds, and the macroscopic tribophyte, Vaucheria are also residents of these ecosystems (Barnhardt et al.

The students and instructors (Drs. Brian Wysor, Roger Williams University; Wilson Freshwater, University of North Carolina at Wilmington; Suzanne Fredericq, University of Louisiana at Lafayette) worked synergistically with the Smithsonian Institution's DNA Barcode initiative. As part of the Bocas Research Station's Training in Tropical Taxonomy program, lecture material included discussions of the current taxonomy of marine macroalgae; an overview and recent assessment of the diagnostic vegetative and reproductive morphological characters that differentiate orders, families, genera and species; and applications of molecular tools to pertinent questions in systematics. Instructors and students collected multiple samples of over 200 algal species by SCUBA diving, snorkeling and intertidal surveys. As part of the training in tropical taxonomy, many of these samples were used by the students to create a guide to the common seaweeds of the Bocas del Toro region. Herbarium specimens will be contributed to the Bocas station's reference collection and the University of Panama Herbarium.

    Welcome Note and Information from the Co-Conveners We hope you will enjoy the NEAS 2004 meeting at the scenic Avery Point Campus of the University of Connecticut in Groton, CT. The last time that we assembled at The University of Connecticut was during the formative years of NEAS (12th Northeast Algal Symposium in 1973). Both NEAS and The University have come along way. These meetings will offer oral and poster presentations by students and faculty on a wide variety of phycological topics, as well as student poster and paper awards. We extend a warm welcome to all of our student members. The Executive Committee of NEAS has extended dormitory lodging at Project Oceanology gratis to all student members of the Society. We believe this shows NEAS members’ pride in and our commitment to our student members. This year we will be honoring Professor Arthur C. Mathieson as the Honorary Chair of the 43rd Northeast Algal Symposium. Art arrived with his wife, Myla, at the University of New Hampshire in 1965 from California. Art is a Professor of Botany and a Faculty in Residence at the Jackson Estuarine Laboratory of the University of New Hampshire. He received his Bachelor of Science and Master’s Degrees at the University of California, Los Angeles. In 1965 he received his doctoral degree from the University of British Columbia, Vancouver, Canada. Over a 43-year career Art has supervised many undergraduate and graduate students studying the ecology, systematics and mariculture of benthic marine algae. He has been an aquanaut-scientist for the Tektite II and also for the FLARE submersible programs.

Global annual harvest is ca. 30.13 million metric tonnes, (valued ca. $11.7 billion USD in 2016) for various commercial applications. The growing scope of seaweed-based applications in food, agricultural fertilizers, animal feed additives, pharmaceuticals, cosmetics and personal care is expected to boost market demand. Agriculture and animal feed applications held the second largest seaweed market share in 2017, and the combined market is anticipated to reach much higher values by 2024 due to the impacts of current research and development targeting enhanced animal health and productivity. In general, seaweeds have been utilized in animal feed as a rich source of carbohydrates, protein, minerals, vitamins and dietary fibers with relatively well-balanced amino acid profiles and a unique blend of bioactive compounds.

To in- vestigate these collections, plastid rbcL and tufA sequencing of six greenish iridescent specimens, including four Um- braulva japonica, were analyzed. Phylogenetic analysis of a concatenated multigene alignment found that the greenish iridescent specimens belonged to a yet undescribed taxon in the genus Umbraulva. We herein propose the name Um. yunseulla sp. nov. for this specimens. Juveniles of Um. yunseulla sp. nov. resemble the generitype Um. japonica in ap- pearance, showing globular to subglobular and funnel-shaped habits, but the blades of this new species are not split longitudinally like those of Um. japonica. Although the multigene phylogenetic tree showed the polyphyletic clade of Umbraulva with respect to the genus Ryuguphycus, Um. yunseulla sp. nov. formed a clade with Um. japonica and Um. amamiensis by weak bootstrap support. These findings,Um. yunseulla sp. nov., highlight the importance of studying the biodiversity of subtidal habitats from Jeju Island, Korea and further emphasize the need for investigations of macroalgae in the mesophotic zone around the Korean peninsula.
