Yap diatoms—from freshwater streams through estuaries and mangroves to the marine coral reefs—had been sampled in 1988 2014 a few species from collections described 2009 report. The present paper documents 168 new records, including seven species, mostly reef habitats, but some interesting mangroves, incorporates records published taxonomic papers. In addition, 44 Mastogloia were separately, bringing taxon total 245. paper, 32 are for Micronesia, while many others neighboring Guam past 15...
Ashworth M.P., Ruck E.C., Lobban C.S., Romanovicz D.K., and Theriot E.C. 2012. A revision of the genus Cyclophora description Astrosyne gen. nov. (Bacillariophyta), two genera with pyrenoids contained within pseudosepta. Phycologia 51: 684–699. DOI: 10.2216/12-004.1The araphid pennate diatom is characterized by an elliptical to circular pseudoseptum at centre one valve; C. tenuis only commonly reported species. New species have included some pseudosepta on both valves, we emended generic...
ABSTRACT. Brown band disease of coral is caused by a ciliate that consumes the tissue corals in genus Acropora. We describe associated with this on Guam, based on: general morphology, division stages, and ciliature observed live protargol-stained specimens; modification oral structures between divisional some aspects behavior field laboratory studies. Porpostoma guamensis n. sp. elongate has typical for genus; cells are 70–500 × 20–75 μm; macronucleus sausage-like, but often bent, positioned...
Mastogloia is a large, morphologically diverse genus of primarily benthic marine species defined by the presence partecta (chambers) on valvocopula (girdle band next to valve). Several genera have been found with valves that resemble but lack ring partecta; most group in freshwaters, especially Aneumastus, there are two genera, both monotypic. A third such has Cuba and described here as Paramastogloia cubana gen. nov., sp. nov. cubana, Mastoneis biformis, Mastogloiopsis biseriata each valve...
The pattern of import and export 14C-labeled assimilates in Macrocystis pyrifera (L.) C. A. Agardh southern California was studied by labeling single blades on fronds, situ, with [14C]NaHCO3 for 24 hours. found to be similar that known dicotyledons: actively growing tissue imported did not export. As a blade reached maturity it began export, at first only acropetally the apex which formed it, later also down frond sporophylls initials base frond, into apical regions juvenile fronds; finally...
A new species of tube-dwelling diatom, unusual in being araphid, is described from benthic coral reef habitats Guam, Palau, Puerto Rico and Jamaica. Gato gen. nov. heteropolar heterovalvar, exhibits very fine striae delimiting a narrow irregular sternum, possesses series rimmed pores on each side the foot pole. One valve frustule has rimoportula at pole, but both valves possess head The generitype, G. hyalinus sp. forms small, branched colonies. Individual cells are oval, slightly tapered...
A study was made of the ultrastructural variation in a group conopeate Nitzschia species, primarily marine species from Guam but also including one freshwater Costa Rica. Fourteen new are described: alcyoneae, asteropeae, carahii, celaenoae, dagmannii, electrae, guamensis, jordanii, lascrucensis, maiae, meropeae, schefterae, spathulatoides, and taygeteae. The valves all these taxa had central raphe-sternum on raised keel; keel arise silica flaps, conopea, valve face depressed below conopea...
Abstract First records of diatoms from Yap, Federated States Micronesia, are presented, including freshwater samples an initial assessment collections made in streams and estuaries marine nearby coral reefs during a brief survey the Wa'ab group islands. Thirty-eight species were documented Yap; these 13 had been reported Guam. In addition we report 25 new for The Guam include especially some large chain-forming Coscinodiscophyceae Mediophyceae, which have observations on living cells their...
Pennate diatoms are important contributors to primary production in freshwater and marine habitats. But the extent of their diversity, ecology, evolution is still largely unknown. This particularly evident among clades pennate without raphe slits, whose diversity likely underestimated due small size features that can be difficult discern under light microscopy. In this study, we described five new araphid genera with eight species based on morphological observations (light electron...
From a study of living materials and specimens in several regional herbaria, list has been drawn up all the common rarer tube-dwelling diatoms eastern Canada. Descriptions, illustrations material acid-cleaned valves, key to species are provided. Most were from Atlantic Provinces St. Lawrence estuary, but few Northwest Territories. By far most is Berkeleya rutilans. Other occurring commonly Quoddy Region Bay Fundy, sporadically space time elsewhere, arc Navicula delognei (two forms), Nav....
Abstract We combined morphological (i.e. live, stained, scanning, and transmission electron microscopy) with morphometric molecular analysis to describe a ciliate species collected from shallow reefs in Guam, grown, maintained our laboratory. The was recognized as member of Euplotidium , compared established the genus: itoi Ito 1958; psammophilus (Vacelet 1961) Borror 1972; arenarium Magagnini Nobili 1964; helgae Hartwig 1980; prosaltans Tuffrau 1985, smalli Lei, Choi Xu, 2002. To obtain...
Abstract. The small subunit rDNA sequence of Maristentor dinoferus (Lobban, Schefter, Simpson, Pochon, Pawlowski, and Foissner, 2002) was determined compared with sequences from other Heterotrichea Karyorelictea. resembles Stentor in basic morphology had been provisionally assigned to Stentoridae. However, our phylogenetic analyses show that is more closely related Folliculinidae. Our results support the creation a separate family for , Maristentoridae n. fam., also confirm grouping...
