Universities Research Journal 2012, Vol. 5, No. 1 The morphotaxonomy and phytogeographical distribution of Colpomenia sinuosa (Mertens ex Roth) Derbes & Solier (Scytosiphonales, Phaeophyta) from Myanmar Khin Khin Gyi1 and Soe Htun2 Abstract The plants of the brown algal genus Colpomenia Derbes & Solier collected from the Rakhine Coastal Region and the Ayeyarwady Delta and Gulf of Martaban Coastal Region from 1971-2010 and deposited in the Department of Marine Science, Mawlamyine University in the forms of herbarium and wet-stack specimens, and fresh specimens collected from Setse coastal areas, were identified as Colpomenia sinuosa (Mertens ex Roth) Derbes & Solier, mainly based on the morphological studies. The distribution ranges of C. sinuosa (Mertens ex Roth) Derbes & Solier along the two Coastal Regions of Myanmar and the geographical regions of the world oceans were presented here. Some ecological notes and potential uses of this species were briefly described. Keywords: Colpomenia sinuous (Mertens ex Roth) Derbes & Solier, distribution, morphology, Myanmar, Phaeophyta, Scytosiphonales, taxonomy. Introduction There are 11 species in the genus Colpomenia (Endlicher) Derbes & Solier commonly occur in all oceans from tropical to temperate regions of the world: C. bullosa (Saunders) Yamada, C. durvillei (Bory de Saint-Vincent) Ramı´rez, C. ecuticulata Parsons, C. expansa (Saunders) Lee, C. mollis Taylor, C. nainativensis Durairatnam, C. peregrina Sauvageau, C. phaeodactyla Wynne et Norris, C. ramosa Taylor, C. sinuosa (Mertens ex Roth) Derbes & Solier, and C. tuberculata Saunders (Saunders 1898, Taylor 1945, Parsons 1982). Very recently, it was recorded 8 species of the genus Colpomenia, viz., C. bullosa, C. ecuticulata, C. expansa, C. phaeodactyla, C. peregrina, C. nainativensis, C. sinuosa, and C. tuberculata in the Asiatic waters (Guiry 2011, Boo et al. 2011). Among these species, 5 species of Colpomenia, namely C. ecuticulata, C. nainativensis, C. peregrina, C. sinuosa, and C. 1 Demonstrator, Department of Marine Science, Mawlamyine University 2 Professor and Head, Department of Marine Science, Mawlamyine University 2 Universities Research Journal 2012, Vol. 5, No. 1 tuberculata were reported from the Indian Ocean Region (IOR) (Silva et al. 1996). Interestingly, the only species of the genus Colpomenia, C. sinuosa (Mertens ex Roth) Derbes & Solier, occur in India (Misra 1966, Krishnamurthy and Joshi 1970, Jha et al. 2009), Bangladesh (Islam 1998), Thailand (Lewmanomont and Ogawa 1995 and Aungtonya and Liao 2002) and Malaysia (Phang 1998, 2006), although two species of the genus Colpomenia, C. sinousa (Mertens ex Roth) Derbes & Solier and C. nainativensis Durairatnam, commonly predominates along the coastal areas of Sri Lanka (Durairanam 1961, Guiry 2011), in the Bay of Bengal (Silva et al. 1996). In Myanmar, Kyi Win (1972), Kyaw Soe and Kyi Win (1977), Soe- Htun et al. (1997, 1999, 2009a) and Soe-Htun (1998, 2005) reported the only species in the genus Colpomenia, C. sinuosa (Mertens ex Roth) Derbes & Solier, from the Rakhine, the Ayeyarwady Delta and Gulf of Mottama (Martaban), and the Tanintharyi Coastal Regions. Recently, Hlaing Hlaing Htoon (2009) also recorded this species from Setse coastal areas. C. sinuosa is used as human food and then prepared as a salad due to the presence of antioxidant properties, a good source of phenols, vitamins, folic and folinic acids, and amino acids and can be used as animal feed, fertilizer and an indicator of metal pollution (Trono 2001). Likewise, forming a considerable amount of C. sinuosa in nature, it can be considered as a raw material for the extraction of alginic acid and alginates on commercial basis beside Sargassum tenerrimum (Levring, Hoppe and Schmid 1969, Rizvi 2003). The objectives of this study are: 1) to revise and update the systematics of the species of Colpomenia based on the morphology of vegetative and reproductive structures, and 2) to know the distribution ranges of this species along both the three Coastal Regions of Myanmar and the world oceans. Materials and Methods Voucher materials of the genus Colpomenia collected from the Rakhine and Ayeyarwady Delta and Gulf of Mottama (Martaban) Coastal Regions were preserved in 4% formalin in seawater and lodged in the Herbarium of Department of Marine Science, Mawlamyine University, Mawlamyine, Myanmar (MMB) from 1971 to 2010, in the forms of herbarium and wet- stack specimens as well as the fresh specimens recently collected from the Universities Research Journal 2012, Vol. 5, No. 1 3 upper intertidal zones of Setse coastal areas (Lat. 15˚ 56′ N, Long. 97˚ 35′ E) in 2010, were used for identification.

Sections of vegetative and reproductive structures of the materials were made by hand using double-edged razor blades. Microscopic measurements of the plants were recorded in micron meter (µm) by using the calibrated ocular meter attached to a BX–41 microscope (Olympus, Tokyo, Japan). External and internal morphologies of vegetative and reproductive structures were photographed with a Panasonic (Lumix) DMC- TZ 15 digital camera and processed using Adobe Photoshop 7.0. This study followed the classification system used by Guiry (2011). Local distribution of C. sinuosa was recorded from the collection sites of the specimens deposited in the Herbarium of Department of Marine Science, Mawlamyine University. Phytogeographical distribution and potential uses of C. sinuosa were consulted with worldwide published literature records available. Moreover, habitats and associated algae of C. sinuosa were also recorded in the field.

We analyzed mitochondrial cox3 sequences from 86 specimens collected in the island and from the nearby Korean Peninsula. Our cox3 phylogeny for the first time confirmed the occurrence of fives species from Ulleungdo Island; Petalonia binghamiae, P. fascia, Planosiphon zosterifolius, and two cryptic species previ- ously identified as Scytosiphon lomentaria. P. binghamiae was relatively homogeneous with three haplotypes. P. fascia comprised four haplotypes, which were grouped into two genetic lineages. S. lomentaria was heterogeneous with nine haplotypes and was divided into two cryptic species; one species clustered with taxa from cold waters while the other clustered with taxa from temperate and cold waters. Low genetic diversity in P. binghamiae while high genetic diversity in S. lomentaria from Ulleungdo Island are comparable to patterns observed from other species from the Korean pen- insula. Ulleungdo Island, although small in size, is an ideal field laboratory to investigate genetic diversity and distribu- tions of economic marine algae.

  • Seaweeds of California Green Algae
    PDF version Remove references Seaweeds of California (draft: Sun Nov 24 15:32:39 2019) This page provides current names for California seaweed species, including those whose names have changed since the publication of Marine Algae of California (Abbott & Hollenberg 1976). Both former names (1976) and current names are provided. This list is organized by group (green, brown, red algae); within each group are genera and species in alphabetical order. California seaweeds discovered or described since 1976 are indicated by an asterisk. This is a draft of an on-going project. If you have questions or comments, please contact Kathy Ann Miller, University Herbarium, University of California at Berkeley.

  • Marine Non-Native Invasive Species in Northern Ireland
    Marine non-native invasive species in Northern Ireland Julia Nunn & Dan Minchin Invasive Species Forum Belfast May 2013 Rapid assessment of marinas for invasive alien species (IAS) in Northern Ireland 1. Develop a target list of species (identifying sector related species) through a desktop literature search. 2. Undertake a rapid assessment of target species using a recognised methodology for selected marina sites around the coast of Northern Ireland. 3. Undertake an examination of the nearby shoreline, near high risk marinas, for invasive species. 4. Where necessary collect voucher specimens of taxa for the NMNI ensuring confirmation of ID is acquired from acknowledged taxonomic experts. 5. Gauge the current level of knowledge of IAS with marina managers. 6. Promote the Invasive Species Ireland Codes of Practice for marina managers and recreational water users to marina staff whilst undertaking fieldwork. Invasive Species Forum Belfast May 2013 Previous studies • 2006 survey – 20 target species • species found: Amphibalanus improvisus, Austrominius modestus, Corella eumyota and Sargassum muticum Target species: 57 Test fieldwork : Carlingford Marina Northern Ireland: 29th Aug- 8th Sept 2012 • 11 marinas (Abundance & Distribution Range (ADR)) • 9 pontoons • 6 shores Parameters: wind; weather; surface water temperature; salinity; cloud coverage; precipitation; tidal conditions; visibility Decontamination procedures Invasive Species Forum Belfast May 2013 Invasive Species Forum Belfast May 2013 Strangford Lough: 17th September – 19th October
