The majority of research to date has focused on the production of DMSP and its major breakdown product, the climatically important gas dimethylsulphide (DMS) (collectively DMS/P), by phytoplankton in the open ocean. -

(Bryopsidales, Chlorophyta) is described from the southern shores of Oman and from the Mediterranean shore of Israel. The new species has a pulvinate to mamillate–globose habit and long narrow utricles. Molecular data from the rbcL gene show that the species is distinct from closely related species, and concatenated rbcL and rps3–rpl16 sequence data show that it is not closely related to other species with similar external morphologies. The recent discovery of well-established populations of C. pulvinatum along the central Mediterranean coast of Israel suggests that it is a new Lessepsian migrant into the Mediterranean Sea. The ecology and invasion success of the genus Codium, now with four alien species reported for the Levantine Sea, and some ecological aspects are also discussed in light of the discovery of the new species. KEY WORDS: Codium pulvinatum, Israel, Lessepsian migrant, Levantine Sea, Oman, rbcL, rps3–rpl16 INTRODUCTION updated), except for ‘TAU’. All investigated specimens are listed in Table S1 (collecting data table). -

Codium (Chlorophyta) species presented in the Galápagos Islands. Hidrobiológica 26 (2): 151-159. ABSTRACT Background. The Galápagos Islands have been the subject of numerous scientific expeditions. The chief source of in- formation on their marine algae is the report published in 1945 by the late William Randolph Taylor on collections made by the Allan Hancock Pacific Expedition of 1934. Prior to this work, there were no published records ofCodium from the Galápagos. Taylor recorder six species of Codium of which C. isabelae and C. santamariae were new descriptions. Goals. On the basis of collections made since 1939, we have reviewed the registry of Codium in these islands. Methods. Com- parative analysis based on morphology and utricle anatomy. Results. Codium isabelae and C. santamariae are combined under the former name. Records of C. cervicorne and C. dichotomum also are referred to C. isabelae, those of C. setchellii are based partly on representatives of C. picturatum, a recently described species from the Mexican Pacific, Panama, Colombia, and Hawaii, and partly on representatives of a species similar if not identical to C. -

Mesozoic and Cenozoic Calcareous Algae, Praecursors of Family Codiaceae
ACTA PALAEONTOLOGICA ROMANIAE V. 6 (2008), P 83-95. MESOZOIC AND CENOZOIC CALCAREOUS ALGAE, PRAECURSORS OF FAMILY CODIACEAE Ovidiu N. DRAGASTAN1 Abstract. It is amaizing how long time was the using of the marine green – algae, Family Codiaceae and the genus Codium, as suffix of many fossil genera (Carpathocodium, Arabicodium, Calabricodium, Madonicodium), without any relation with the real morphology of the Recent genus Codium. The genus Codium is well represented on warm – cool transitional marine coasts or in the inner shelf environments of carbonate platform. The genus Codium has an unique structural plan with thallus multibranched, noncalcareous, vesiculous crossed by medullary siphons and only one layer of cortical utricles. The utricles show a great anatomical diversity with diagnostic value in separating the approximately 100 Recent species. Until now, a real representative of the Recent Family Codiaceae in the fossil state was not found. Also, the same situation is with Recent genus Pseudocodium (Family Pseudocodiaceae). Contrary, the fossils praecursors of the Recent Codiaceae were recorded, described and included now, for the first time in the Family Praecodiaceae nov. fam. This family only with fossil representatives contains calcareous thalli composed by cylindrical branches crossed by medullary siphons, few in number (4 to 6, rarely 8) and only one utricles layer. The utricles layer is variable in morphology from species to species. Beside the late Triassic Hydracara kubeae Dragastan et al.2000 are introduced the following taxa: Lupertosinnium bariensis nov.gen.nov.sp. (early Barremian), L. banatensis n.sp. (late Barremian – early Aptian ), Alpinium tragelehni nov.gen.nov.sp. (Thanetian) and Atlasinium nov.gen. -
From Introduced Species to Invader: What Determines Variation in the Success of <Emphasis Type="Italic">Codium F
HELGOL,~NDER MEERESUNTERSUCHUNGEN Helgol~inder Meeresunters. 52, 277-289 11999) From introduced species to invader: what determines variation in the success of Codiumfragile ssp. tomentosoides (Chlorophyta) in the North Atlantic Ocean? Annelise Sabine Chapman ~ * * Institute of Marine Sciences, University of Portsmouth, Ferry Rd., Eastney, Portsmouth P04 9LY, UK ABSTRACT: The green alga Codium fragile ssp. tomentosoides (Chlorophyta) has been introduced accidentally and successfully from Japan to many shores of the northern and southern hemi- spheres, including those of the Northeast and Northwest Atlantic Ocean. On most European coasts, Codium occurs regularly but at low abundances in the intertidal zone and is absent from subtidal habitats, tn contrast. Codium is extremely abundant in subtidal kelp beds in the Northwest Atlantic Ocean where it often reaches nuisance proportions. This differential success cannot be accounted for by either the properties of the invader or by physico-chemical differences between invaded coasts. A theoretical comparison between two regions on opposite sides of the Atlantic Ocean, i.e. Eastern Nova Scotia, Canada, and south central Britain, illustrates how the resident benthic com- munity may determine the difference in relative abundance of Codium in subtidal habitats be- tween northeast America and Europe. In this review, low floral species diversity, biological distur- bance and facilitation by a previous species invasion are suggested as potential factors for the es- tablishment, success and abundance of Codium in the Northwest Atlantic Ocean, but these require testing in field experiments. INTRODUCTION Studies of the ecology of species introductions into novel marine environments have often emphasized (1) the properties of successfully invading species, (2) the character- istics of frequently invaded communities or (3) the transport vectors involved in over- coming barriers of space, climate or habitat (e.g. -

First Record of Genuine Codium Mamillosum Harvey (Codiaceae, Ulvophyceae) from Japan
Bull. Natl. Mus. Nat. Sci., Ser. B, 43(4), pp. 93–98, November 22, 2017 First record of genuine Codium mamillosum Harvey (Codiaceae, Ulvophyceae) from Japan Taiju Kitayama Department of Botany, National Museum of Nature and Science, Amakubo 4–1–1, Tsukuba, Ibaraki 305–0005, Japan E-mail: [email protected] (Received 29 August 2017; accepted 27 September 2017) Abstract A marine benthic green alga, Codium mamillosum Harvey (Codiaceae, Bryopsidales, Ulvophyceae) was collected from the mesophotic zone off Chichi-jima Island, Ogasawara Islands, Japan. In Japan, at the end of the 19th century, this species name was used by Okamura (in Matsumura and Miyoshi, 1899) for his specimens of solid globular Codium collected from main islands of Japan, afterward it was synonymized by Silva (1962) into Codium minus (O.C. Schmidt) P.C.Silva as “Codium mamillosum sensu Okamura”. The present alga collected recently from Oga- sawara Islands was identified as a genuine C. mamillosum because the thalli have relatively larger utricles (550–1100 µm in diameter) than those of C. minus. Key words : Codiaceae, Codium mamillosum, Japan, marine benthic green alga, Ogasawara Islands, Ulvophyceae. In the end of the 18th century, the marine Harvey (1855) based on the specimens collected green algal genus Codium (Codiaceae, Bryopsi- from Western Australia, whose appearance was dales, Ulvophyceae) was established by Stack- described as “a very solid, green, mamillated house (1795). This genus has 120–144 species (having nipples) ball”. In Japan, Okamura in (Huisman, 2015; Guiry and Guiry, 2017), which Matsumura and Miyoshi (1899) and Okamura are extremely various in external morphology: (1915) identified the specimens of solid globular flattened to erect, dorsiventral or isobilateral, Codium collected from main islands of Japan as branched or unbranched, complanate to terete, C. -
