Dennison b, M. Waycott c a Department of Natural Resources, University of New Hampshire, Jackson Estuarine Laboratory, Durham, NH 03824, USA b Integration and Application Network, University of Maryland Center for Environmental Science, Cambridge, MD 21613, USA c School of Marine and Tropical Biology, James Cook University, Townsville, 4811 Queensland, Australia Received 1 February 2007; received in revised form 31 May 2007; accepted 4 June 2007 Abstract Seagrasses, marine flowering plants, are widely distributed along temperate and tropical coastlines of the world. Seagrasses have key ecological roles in coastal ecosystems and can form extensive meadows supporting high biodiversity. The global species diversity of seagrasses is low (b60 species), but species can have ranges that extend for thousands of kilometers of coastline. Seagrass bioregions are defined here, based on species assemblages, species distributional ranges, and tropical and temperate influences. Six global bioregions are presented: four temperate and two tropical. The temperate bioregions include the Temperate North Atlantic, the Temperate North Pacific, the Mediterranean, and the Temperate Southern Oceans. The Temperate North Atlantic has low seagrass diversity, the major species being Zostera marina, typically occurring in estuaries and lagoons. The Temperate North Pacific has high seagrass diversity with Zostera spp. in estuaries and lagoons as well as Phyllospadix spp. in the surf zone. The Mediterranean region has clear water with vast meadows of moderate diversity of both temperate and tropical seagrasses, dominated by deep-growing Posidonia oceanica. -
Reassessment of Seagrass Species in the Marshall Islands1
Micronesica 2016-04: 1–10 Reassessment of Seagrass Species in the Marshall Islands 1 ROY T. TSUDA Department of Natural Sciences, Bishop Museum, 1525 Bernice Street, Honolulu, HI 96817, USA [email protected] NADIERA SUKHRAJ U.S. Fish and Wildlife Service, Pacific Islands Fish and Wildlife Office, 300 Ala Moana Blvd., Honolulu, HI 96850, USA [email protected] Abstract—Recent collections of specimens of Halophila gaudichaudii J. Kuo, previously identified as Halophila minor (Zollinger) den Hartog, from Kwajalein Atoll in September 2016 and the archiving of the specimens at BISH validate the previous observation of this seagrass genus in the Marshall Islands. Previously, no voucher specimen was available for examination. Molecular analyses of the Kwajalein Halophila specimens may demonstrate conspecificity with Halophila nipponica J. Kuo with H. gaudichaudii relegated as a synonym. Herbarium specimens of Cymodocea rotundata Ehrenberg and Hemprich ex Ascherson from Majuro Atoll were found at BISH and may represent the only specimens from the Marshall Islands archived in a herbarium. Cymodocea rotundata, however, has been documented in past literature and archived via digital photos in its natural habitat in Majuro. The previous validation of Thalassia hemprichii (Ehrenberg) Ascherson with specimens, and the recent validation of Halophila gaudichaudii and Cymodocea rotundata with specimens reaffirm the low coral atolls and islands of the Marshall Islands as the eastern limit for the three species in the Pacific Ocean. Introduction In a review of the seagrasses in Micronesia, Tsuda et al. (1977) reported nine species of seagrasses in Micronesia with new records of Thalassodendron ciliatum (Forsskål) den Hartog from Palau, and Syringodium isoetifolium (Ascherson) Dandy and Cymodocea serrulata (R. -

The Sea-Grasses of Brazil Ligulate, Linear, Leaf-Tip
Acta Bot. Need. October 512-516 21(5), 1972, p. The sea-grasses of Brazil C. den Hartog Rijksherbarium, Leiden There is still hardly anything known aboutthe occurrence of sea-grasses in South America. The number of records is extremely small. Therefore, one wonders whether these plants are extremely rare or absent along long stretches of coast, whether it is that have been overlooked or just they by botanists. It seems that the latterapplies to the coast of Brazil, from where up to nowonly two collections had been recorded (Setchell 1934; den Hartog 1970). Thanks to the active, gratefully acknowledged co-operation of Dr. Liliane Forneris (Universidade de Sao Paulo) I received a number of sea-grasses from several places along the Brazilian coast. I am also indebted to Dr. Emilia Santos (Museu Nacional, Rio de Janeiro) and Dr. Graziela M. Barroso (Jardim Botanico, Rio de Janeiro) for and sending me a specimen a photograph, respectively, of Halophila decipiens. Further, I am grateful to Dr. V. J. H. de Jilovice de Sternberg (Com- panhia ‘Algimar’, Rio de Janeiro) for his co-operation in obtaining material. At present there are 5 species now known from Brazil.

An Overview of Cuban Seagrasses
Bull Mar Sci. 94(2):269–282. 2018 research paper https://doi.org/10.5343/bms.2017.1014 An overview of Cuban seagrasses Centro de Investigaciones Beatriz Martínez-Daranas * Marinas, Universidad de La Habana, Calle 16 No. 114, Ana M Suárez Miramar, Playa, Havana, 11300, Cuba. * Corresponding author email: <[email protected]>. ABSTRACT.—Here, we present an overview of the current knowledge of Cuban seagrasses, including distribution, status, threats, and efforts for their conservation. It has been estimated that seagrasses cover about 50% of the Cuban shelf, with six species reported and Thalassia testudinum K.D. Koenig being the most dominant. Seagrasses have been studied primarily in three areas in Cuba (northwest, north-central, and southwest). Thalassia testudinum and other seagrasses exhibit spatial and temporal variations in abundance, and updating of their status and distribution is needed. The main threat to Cuban seagrass ecosystems is low seawater transparency due to causes such as eutrophication and erosion. High salinities limit their distribution in the Sabana-Camagüey Archipelago, partly the result of freshwater dams and roads. Seagrass meadows play important ecological k roles and provide many ecosystem services in Cuba, with efforts underway to preserve this ecosystem. Research and Marine Ecology and Conservation in Cuba management projects are directed toward integrated coastal zone management, including a ban on trawl fisheries and the Guest Editors: extension of marine protected areas to contain more seagrass Joe Roman, Patricia González-Díaz meadows. In addition to updating species distributions, it is Date Submitted: 17 February, 2017. urgent that managers and researchers in Cuba examine the Date Accepted: 22 November, 2017. -

Daru) Running head: Phylogenetic regionalization of seagrasses 1 Abstract While our knowledge of species distributions and diversity in the terrestrial biosphere has increased sharply over the last decades, we lack equivalent knowledge of the marine world. Here, we use the phylogenetic tree of seagrasses along with their global distributions and a metric of phylogenetic beta diversity to generate a phylogenetically-based delimitation of marine phytoregions (phyloregions). We then evaluate their evolutionary affinities and explore environmental correlates of phylogenetic turnover between them. We identified 11 phyloregions based on the clustering of phylogenetic beta diversity values. Most phyloregions can be classified as either temperate or tropical, and even geographically disjunct temperate regions can harbor closely related species assemblages.
