Marine Organism Classification Main Summary Table. The host seaweeds influenced the associated diatoms mainly through its morphology and surface texture and roughness to provide a point of attachment and shelter for host-adapted species. LUMCON 8124 Highway 56 Chauvin, LA 70344. Phytoplankton play a key role in the ecology of the marine ecosystem, and they are also an integral part in the regulation of the amount of carbon in the atmosphere; therefore, changes in their patterns of distribution and abundance can have a significant impact on the entire ecosystem. In: Deutsche Sudpolar-Expedition, 1901-1903, herausgegeben von Erich von Drygalski. The Thalassionema spp. In its broad features the fine structure of Thalassiothrix frauenfeldiiappeared to be somewhat similar to that of Thalassionema bacillaris, while the fine structure of Thalassiothrix longissimaand T. antarcticasuperficially resembled that of Thalassionema nitzschioides. A total of 45 phytoplankton species were identified during the study period. Rather than studying this process chemically, we have elected to search for the genes involved in EPS production and secretion. Description of the study area. (1928). Romero et al. Datasets. Our analyses showed that sequences from oomycetes, diatom Thalassionema frauenfeldii and land plants formed a strongly supported clade, whereas other photosynthetic sequences, including red algae and cyanobacteria, formed another large group with only modest support. Tabellaria sp. Frenguelli (1941) mentioned that he found valves with 9–10 areolae within 10 μm and illustrated a linear, fragmentary specimen that, according to the valve outline and areola density, might also be attributed to Thalassionema frauenfeldii, but not to T. synedriforme .

Return to master index Processed by T. Rosatti. Die Marinen Diatomeen der Deutschen Südpolar-Expedition, 1901-1903. Diatoms, responsible for nearly half of oceanic primary production, have evolved molecular strategies for coping with variable iron concentrations. 54. 264 sites. Striatella unipunctata 53. The rhizosolenid diatom laminae are … (Thalassionema frauenfeldii, Cosnodiscus centralis, Odontella mobiliensis and Ceratium trichoceros) found in the costal waters of Ilaje, Ondo state (oil producing area) and Bar-beach Lagos (non-oil producing area) under controlled laboratory conditions. 111022 non-quantitative. The needle-shaped frustules of the diatoms Thalassionema Grunow and Thalassiothrix Cleve et Grunow are furnished with uniquely structured areolae which appear as a row of depressions along each edge of the valve. Most of the dominant epiphytes were in smaller Of these, 19 species belong to centric diatom, 14 species belong to pennate diatom, 11 species belong to dinoflagellates and 1 species belong to blue green alga, Trichodesmiul11 erythraeum. ‘BlueH20’). eccentrica and Thalassionema cf. Cleve Thalassiosira rotula Meunier Thalassiosira sp. Thalassionema frauenfeldii is a perennial species developing successfully in winter when other diatoms are absent (Travers, 1971). Diatoms are mostly unicellular, golden brown, green or dark brown algae 2 to 200 microns in size (occasionally several millimetres long), their cell walls composed of silica with an organic coating. [28] Group 4, composed by species typical of pelagic waters such as Actinocyclus octonarius, Thalassionema frauenfeldii and Thalassionema bacillare, describes 9.4% of the total variance. Cite as: Deep Sea Drilling Project (1989): Archive of Core and Site/Hole Data and Photographs from the Deep Sea Drilling Project (DSDP).National Geophysical Data Center, NOAA. This Genus currently has 3 taxonomic siblings ( listed below) and an expanded tree of 3 members ( self + siblings + sub-siblings ). Thalassionema frauenfeldii was the dominant species at chlorophyll maximum depth distributed in most of the study area except the Gulf of Tonkin. Effects of different crude oil concentrations (6 to 50 ppm) on population of Coscnodiscus centralis, Thalassionema frauenfeldii, Odontella mobiliensis, and Ceratium trichoceros at different exposure periods (6 to 42 h) via microcosm experiments were then assessed. frauenfeldii.

It is a collaborative hub for the scientific community and a public resource for citizens at large. Salinity, nitrate and silicate were the most important environmental factors regulating the variation of phytoplankton community. Share sensitive information only on official, secure websites. Diatoms were grown under continuous light at an intensity of 110–150 μmol quanta m −2 s −1, except for Thalassionema frauenfeldii which was grown under a 13/11 light/dark cycle due to an inability to grow under continuous light conditions.

Alexandrium was the selected genus for studying its distribution. Thalassionema frauenfeldii 56. Barcode of Life Data System (BOLD) It is an online workbench and database that supports the assembly and use of DNA barcode data. Higher cell abundance as well as greater cell growth rate in exponential growth phase was detected for all monitored species in phosphorus rich medium. 2 52. doi:10.7289/V54M92G2 [access date].
