Training in Tropical Taxonomy 9-23 July, 2008 Tropical Field Phycology Workshop Field Guide to Common Marine Algae of the Bocas del Toro Area Margarita Rosa Albis Salas David Wilson Freshwater Jesse Alden Anna Fricke Olga Maria Camacho Hadad Kevin Miklasz Rachel Collin Andrea Eugenia Planas Orellana Martha Cecilia Díaz Ruiz Jimena Samper Villareal Amy Driskell Liz Sargent Cindy Fernández García Thomas Sauvage Ryan Fikes Samantha Schmitt Suzanne Fredericq Brian Wysor From July 9th-23rd, 2008, 11 graduate and 2 undergraduate students representing 6 countries (Colombia, Costa Rica, El Salvador, Germany, France and the US) participated in a 15-day Marine Science Network-sponsored workshop on Tropical Field Phycology. 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. -
2004 University of Connecticut Storrs, CT
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. -

With more than 100 species described on a morphological basis, an 5 accurate evaluation of its diversity is still missing. Here we analysed 277 chloroplast-encoded 6 gene sequences (43 from this study), representing 35 nominal species of Ulva from the 7 Pacific, Indian Ocean, and Atlantic (with a particular emphasis on the Brazilian coast) in an 8 attempt to solve the complex phylogenetic relationships within this widespread genus. -
Ulvales, Ulvophyceae) in Mikawa Bay, Japan, Deduced from ITS2 Rdna Region Sequences
Algae Volume 22(3): 221-228, 2007 Species Diversity and Seasonal Changes of Dominant Ulva Species (Ulvales, Ulvophyceae) in Mikawa Bay, Japan, Deduced from ITS2 rDNA Region Sequences Hiroshi Kawai1*, Satoshi Shimada2, Takeaki Hanyuda1, Teruaki Suzuki3 and Gamagori City Office4 1Kobe University Research Center for Inland Seas, Rokkodai, Nadaku, Kobe 657-8501, Japan 2Creative Research Initiative ‘Sousei’, Hokkaido University, Sapporo, 060-0810 Japan 3Aichi Fisheries Research Institute, Gamagori 443-0021, Japan 4Asahimachi, Gamagori 443-8601, Japan Frequent occurrences of green tides caused by Ulva species (Ulvales, Ulvophyceae) associated with eutrophication along enclosed coasts are currently causing environmental problems in coastal ecosystems. In addition, increasing intercontinental introductions of coastal marine organisms, including Ulva, are also a serious issue. However, due to the considerable morphological plasticity of this genus, the taxonomy of Ulva species based on morphological stud- ies is problematic. Therefore, in order to elucidate the species diversity and seasonal changes of the dominant Ulva species in Mikawa Bay, central Honshu, Japan, we made seasonal collections of Ulva species at seven localities, and identified the dominant species using the ITS2 rDNA region sequences. We identified the following nine taxa as common Ulva species in the area: 1) Ulva pertusa Kjellman; 2) U. ohnoi Hiraoka et Shimada; 3) U. linza L.; 4) U. califor- nica Wille; 5) U. flexuosa Wulfen; 6) U. fasciata Delile; 7) U. compressa L.; 8) U. armoricana Dion et al.; 9) U. scandinavica Bliding. Among the species, U. pertusa was most common and dominant from spring to summer, and U. ohnoi from autumn to winter. Ulva californica and U. -
Developing Systems for the Commercial Culture of Ulva Species in the UK
Developing systems for the commercial culture of Ulva species in the UK Guang Gao A thesis submitted to Newcastle University in candidature for the Degree of Doctor of Philosophy School of Marine Science and Technology May 2016 Abstract The green seaweed, Ulva, is highly valued in terms of animal feed, food and biofuel, as well in the delivery of crucial remediation services including wastewater treatment and CO2 removal. Accordingly, Ulva cultivation has gained significant research interest worldwide. Notwithstanding these research efforts, Ulva cultivation is still in its infancy and knowledge to underpin such developments remains limited. A common challenge in Ulva cultivation is the fluctuating productivity with time due to vegetative fragmentation and/or periodic reproduction. In this study, three methods were employed to address this challenge. Firstly, culture conditions were optimised to establish a balance between growth and reproduction. Secondly, a refined culture method was developed, which more than tripled growth of Ulva over an 18-day cultivation as compared to a standard method. Thirdly, a sterile strain was obtained by mutating a wild strain with ultraviolet radiation. This new strain grew five times faster over an 18-day cultivation and absorbed nitrate and phosphate 40.0% and 30.9% quicker compared to the wild strain respectively. The chemical composition of the sterile strain showed a lipid content of more than double that of the wild strain, while the protein content was 26.3% lower than the wild strain. Several tissue preservation techniques were developed to enable settlement and growth trials to be conducted on demand. The merits or otherwise of the preservation techniques were determined for gametes, germlings and thalli.
