This was performed at the Phycology Research Group (www.phycology.ugent.be) and at the Institute of Environment & Marine Sciences, Silliman University, Philippines. ii iii ACKNOWLEDGEMENTS First of all, I would like to acknowledge the people who made it possible so I could start with this PhD project on Portieria. It all started from Prof. Olivier De Clerck‘s discussion with Prof. John West about this alga. Next thing that happened was the endorsement of Prof. West and Prof. Lawrence Liao of my application for VLIR PhD scholarship. Prof. Dr. Eric Coppejans has supported my PhD application and has always welcomed me in his lab since 2003 when I started to work on Dictyota. A good number of Prof. Coppejans‘ Portieria collections had been included in this work. I would also like to thank my co-promoter in the Philippines Prof. Dr. Hilconida Calumpong, for her confidence in me. Despite of not knowing me in 2005, she accepted my proposal and supported my PhD scholarship application. Prof. Calumpong‘s support on this research ranged from advice on experimental design and field work, reserving an exclusive room and an outdoor space for my experimental work at the Silliman laboratory, and reviewing my manuscript drafts. Prof. Calumpong also gave me opportunities for exposure by inviting me to present during the Friday laboratory meetings. I would also like to mention the help extended by her entire staff, especially Jacinta Lucañas, Julieta Echaves and Mrs. Pacita Raterte for lab equipment and research fund concerns, and the generally friendly lab atmosphere created by her entire staff and PhD students. Annalie Candido, Rio Naguit, Wilson Tisera, Amida Diwata Macansantos also helped to collect Portieria at Apo Island, Bunaken Island, Indonesia, and Spratley Islands. Zaccharias “Nong Iyas” Generoso has been a great assistance in the field, in my grazing experiments and who entertained me with his amusing field research stories in the old days. I am also indebted to Abner Bucol who assisted me for two years even during rough seas in my monthly surveys in Siquijor and Siaton and during my first trip to Batanes. Apart from allowing me to hire their boats, keen fishermen from Siquijor suggested good sites for Portieria. Some friends from college and NGO days also got dragged into this affair of collecting Portieria, like Rey Ladiao, Florabel Fumar, Bernie Caliñajan, William Villaver, Peddy Caet and Nonoy of Liloan, Cebu. Thanks are also due to Basco, Batanes Mayor Manuel Viola who forwarded my letter of intent to collect to the Municipal Environment Officer, Francis Dominggo, who in turn assisted during the Batanes collections. Generous phycologists from different institutions have also enriched the number of my samples such as Alison Sherwood, Tom Cowling, Max Hommersand, Willem Prud’homme Van Reine, Stefano Draisma, Tom Schils, Diane and Mark Littler. David Reid Wiseman generously sent a copy of his PhD thesis of 1973 on Ochtodes and Chondrococcus. iv In Ghent, despite of all the scheduling difficulties and the technical troubles, Renaat Dasseville made it possible that I could use the GC-MS. I am also indebted to him for the GC-MS knowledge that he imparted. Joannamel Colo, the Ecomama thesis student I supervised, performed the traditional measurements on Portieria and also a portion of the chemical work. Frederic Lynen of the chemistry department also welcomed me in his lab and allowed me to use HPLC and GC-MS machines during the exploratory period of my Portieria extracts. I am also sincerely thankful to all the members of the Phycology Research Group for the generosity with their time, knowledge and all the help of any form extended to me during my PhD years. My DNA extraction, PCR and DNA sequencing work had been greatly assisted by Caroline Vlaeminck and Sofie D’hondt. Klaas Pauly and Heroen Verbruggen have also contributed to my Portieria samples. Special thanks are also due to the members of the brainstorming team who helped shape the direction of the molecular aspect of this research composed of Heroen Verbruggen, Frederik Leliaert and Olivier De Clerck. I greatly appreciate the administrative help provided by Christelle Vankerckhove but most of all her kindness, warmth and motherly demeanor. I shall also thank Agniezka Lipinska, Frédérique Steen, and Ana Tronholm, my lab roommates, for bringing fun and the wonderful and comforting conversations. I greatly appreciate all the kindness and help in the analyses and manuscript writing of my co-promoter Frederik Leliaert, from whom I learned a lot. I admire his effective way of transferring knowledge. Finally, I am greatly indebted to my promoter, Olivier De Clerck for believing that I can do a PhD, for all these learning opportunities (too many to mention) that he made possible for me, the supervision since my master‘s thesis period (which resulted to a best thesis award from VLIZ), during the thesis proposal writing and for always pushing me to do better. I appreciate the keenness he gave in every aspect of my work and also that ―hands-on‖ training. I leave my sincerest thanks to these promoters and will take with me all the lessons I have learned from them here in Ghent. I thank my thesis committee for the academic dedication exercised on reviewing the pre-defense version of this manuscript. It has made me realize the important role of a critique committee in improving the quality of an academic work. Portieria research would not have been possible without the PhD scholarship provided by the Flemish Interuniversity Council (VLIR) from 2006 to 2010. VLIR also funded my scholarship for a master‘s degree in Ecological Marine Management at the Free University of Brussels (VUB) from 2002 to 2004. The Global Taxonomy Initiative under the Royal Belgian Institute of Natural Sciences came to the rescue through Dr. Yves Samyn by providing fund for my trip back to and living allowance in Belgium in 2011. v Claire Van Maercken, my landlady of four years in Ghent, deserves sincere appreciation for a service to foreign students, homely accommodation and the conversations. My family gave inspiration and extended much needed help during the sampling and labwork in Silliman. -D.A. Payo- September 2011 Ghent, Belgium This academic work was performed in collaboration with Silliman University – Institute of Environmental and Marine Studies, Filipino biologists and locals of sampling sites in the Philippines. Prior informed consent was obtained from the mayor and the municipal environment natural resources officer of Basco. Portieria species have no economic value and are not classified by CITES (IUCN) as threatened or endangered. Export permit has been granted by the Bureau of Fisheries and Aquatic Resources. All other Indo-Pacific specimens have been generously donated by phycologists from different institutions. vi vii CONTENTS Exam Committee ...................................................................................................... ii Acknowledgements ................................................................................................. iv Contents .................................................................................................................. viii Abbreviations and Acronyms ............................................................................... xii List of Tables .......................................................................................................... xiv List of Figures ........................................................................................................ xvi 1 General introduction........................................................................................ 1 1.1 Marine biodiversity and secondary metabolites ............................................. 1 1.2 Portieria: a taxonomic perspective ..................................................................... 5 1.3 Portieria hornemannii .............................................................................................. 7 1.4 Cryptic species diversity ................................................................................... 10 1.4.1 Species delimitation approaches ......................................................

    Bioprocess Engineering of Cell and Tissue Cultures for Marine Seaweeds

    Aquacultural Engineering 32 (2004) 11–41 Bioprocess engineering of cell and tissue cultures for marine seaweeds Gregory L. Rorrer a,∗, Donald P. Cheney b a Department of Chemical Engineering, Oregon State University, Corvallis, OR 97331, USA b Department of Biology, Northeastern University, Boston, MA 02115, USA Received 5 December 2003; accepted 8 March 2004 Abstract Seaweeds are a rich source of valuable compounds including food additives and biomedicinals. The bioprocess engineering of marine macroalgae or “seaweeds” for the production of these compounds is an emerging area of marine biotechnology. Bioprocess technology for marine macroalgae has three elements: cell and tissue culture development, photobioreactor design, and identification of strategies for eliciting secondary metabolite biosynthesis. In this paper, the first two elements are presented. Firstly, the development of phototrophic cell and tissue culture systems for representative species within brown, green, and red macroalgae is described. In vitro culture platforms include microscopic gametophytes, undifferentiated callus filaments, and “microplantlets” regenerated from callus. Sec- ondly, the controlled cultivation of these phototrophic culture systems in stirred tank, bubble-column, airlift, and tubular photobioreactors is described. Limiting factors on biomass production in photo- bioreactors including light delivery, CO2 transfer, and macronutrient delivery are compared. Finally, a mathematical model that integrates light delivery, CO2 delivery, and macronutrient delivery into the material balance equations for biomass production in a perfusion bubble-column photobioreac- tor is presented, and model predictions are compared to biomass production data for microplantlet suspension cultures of the model red alga Agardhiella subulata. © 2004 Elsevier B.V.

The main objective of this study was to evaluate the effects of this invasive seaweed on marine invertebrates by exposing the common prawn Palaemon elegans and the marine snail Gibbula umbilicalis to the exudate of this macroalgae. The seaweed was collected and placed in tanks, for 12 hours, in the dark in a 1:10 ratio. Afterwards the media containing its secondary metabolites was collected for further testing.

Received: 17 August 2011; in revised form: 1 November 2011 / Accepted: 8 November 2011 / Published: 21 November 2011 Abstract: Possible sources of variation in non-polar secondary metabolites of Portieria hornemannii, sampled from two distinct regions in the Philippines (Batanes and Visayas), resulting from different life-history stages, presence of cryptic species, and/or spatiotemporal factors, were investigated. PCA analyses demonstrated secondary metabolite variation between, as well as within, five cryptic Batanes species. Intraspecific variation was even more pronounced in the three cryptic Visayas species, which included samples from six sites. Neither species groupings, nor spatial or temporal based patterns, were observed in the PCA analysis, however, intraspecific variation in secondary metabolites was detected between life-history stages. Male gametophytes (102 metabolites detected) were strongly discriminated from the two other stages, whilst female gametophyte (202 metabolites detected) and tetrasporophyte (106 metabolites detected) samples were partially discriminated.

However, until 2016, it was found only in low coverage and in few localities with hard substrata. The paper reports a recent bloom of these tetrasporophytes in the mediolittoral belt of the Bay of Piran, where thalli of this red alga overgrew the articularted coralline alga Corallina officinalis. The sites affected by this large expansion of tetrasporophytes of A. armata should be regularly monitored in the future, in order to point out which environmental factors are responsible for such phenomenon, and to formulate proper conclusions on the status of this non-indigenous alga in the coastal area concerned.

There are 35 genera, 130 species of green algae; 23 genera, 59 species of brown algae; and 79 genera, 147 species of red algae which represent a rich algal flora for the subtropics. Introduction This New Caledonian benthic algal catalog consists of two sections, and generally follows the format as presented by Tsuda and Wray ( 1977) for Micronesian benthic algae and by Payri and Meinesz (1985) for French Polynesian benthic algae. The first section (1. Classification) provides a list of the classes, orders, families and genera of those marine benthic algae within the Divisions Chlorophyta, Phaeophyta and Rhodophyta reported from New Caledonia. The second section (II. Checklist with References and Localities) provides an al­ phabetized checklist of all taxa (i.e., species, varieties and forms) within the three Divi­ sions reported from publications up to 1987. Each taxon is followed by the name of the author(s) who reports it from New Caledonia, the year of publication, and the collection site (if known). The New Caledonian specimens are located in various herbaria-ORSTOM her­ barium and C. Garrigue's herbarium, ORSTOM (lnstitut Francais de Recherche Scientifi­ que pour le Developpement en Cooperation), Noumea; E. Vieillard's herbarium, Museum National d'Histoire Naturelle, Paris (PC), and University of Caen (CN); G.

Delineating the Gigartinales sensu stricto Gary W. Saunders, Anthony Chiovitti, and Gerald T. Kraft Abstract: Nuclear small-subunit ribosomal DNA sequences were determined for 65 members of the Gigartinales and related orders. With representatives of 15 families of the Gigartinales sensu Kraft and Robins included for the first time, our alignment now includes members of all but two of the ca. 40 families. Our data continue to support ordinal status for the Plocamiales, to which we provisionally transfer the Pseudoanemoniaceae and Sarcodiaceae. The Halymeniales is retained at the ordinal level and consists of the Halymeniaceae (including the Corynomorphaceae), Sebdeniaceae, and Tsengiaceae. In the Halymeniaceae, Grateloupia intestinalis is only distantly related to the type spe- cies, Grateloupia filicina, but is closely affiliated with the genus Polyopes. The Nemastomatales is composed of the Nemastomataceae and Schizymeniaceae. The Acrosymphytaceae (now including Schimmelmannia, formerly of the Gloiosiphoniaceae) and the Calosiphoniaceae (represented by Schmitzia) have unresolved affinities and are considered as incertae sedis among lineage 4 orders. We consider the Gigartinales sensu stricto to include 29 families, although many contain only one or a few genera and mergers will probably result following further investigation. Although the small-subunit ribosomal DNA was generally too conservative to resolve family relationships within the Gigartinales sensu stricto, a few key conclusions are supported. The Hypneaceae, questionably distinct from the Cystocloniaceae on anatomical grounds, is now subsumed into the latter family. As recently suggested, the Wurdemanniaceae should be in- corporated into the Solieriaceae, but the latter should not be merged with the Areschougiaceae.
