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.

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. -

China Abstract: A new freshwater species of Ulvella, U. tongshanensis H. ZHU et G. LIU, is described from material collected from rocks under small waterfalls in Hubei Province, China. This unusual species differs from other species in the genus by the macroscopic and upright parenchymatous thalli, and by the particular habitat (most Ulvella species occur in marine environments). Phylogenetic analyses of plastid encoded rbcL and tufA, and nuclear 18S rDNA sequences, pointed towards the generic placement of U. tongshanensis and also showed a close relationship with two other freshwater species, Ulvella bullata (Jao) H. ZHU et G. LIU, comb. nov. and Ulvella prasina (Jao) H. ZHU et G. LIU, comb. nov. The latter two were previously placed in the genus Jaoa and are characterized by disc–shaped to vesicular morphology. Our study once again shows that traditionally used morphological characters are poor indicators for phylogenetic relatedness in morphologically simple algae like the Ulvellaceae. -

DNA Barcoding of a New Record of Epi-Endophytic Green Algae Ulvella Leptochaete (Ulvellaceae, Chlorophyta) in India
DNA barcoding of a new record of epi-endophytic green algae Ulvella leptochaete (Ulvellaceae, Chlorophyta) in India FELIX BAST* , SATEJ BHUSHAN and AIJAZ AHMAD JOHN Centre for Biosciences, Central University of Punjab, Bathinda 151 001, India *Corresponding author (Fax, +91 164 2430586; Email, [email protected]) Epi-endophytic green algae comprise one of the most diverse and phylogenetically primitive groups of green algae and are considered to be ubiquitous in the world’s oceans; however, no reports of these algae exist from India. Here we report the serendipitous discovery of Ulvella growing on intertidal green algae Cladophora glomerata and benthic red algae Laurencia obtusa collected from India. DNA barcodes at nuclear ribosomal DNA Internal Transcriber Spacer (nrDNA ITS) 1 and 2 regions for Indian isolates from the west and east coasts have been generated for the first time. Based on morphology and DNA barcoding, isolates were identified as Ulvella leptochaete. Phylogenetic reconstruction of concatenated dataset using Maximum Likelihood method differentiated Indian isolates from other accessions of this alga available in Genbank, albeit with low bootstrap support. Monophyly of Ulvella leptochaete was obvious in both of our phylogenetic analyses. With this first report of epi-endophytic algae from Indian territorial waters, the dire need to catalogue its cryptic diversity is highlighted and avenues of future research are discussed.

Laboratory Studies on Vegetative Regeneration of the Gametophyte of Bryopsis Hypnoides Lamouroux (Chlorophyta, Bryopsidales)

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.
