Bacteriastrum Comosum
''Bacteriastrum'' is a genus of diatoms in family Chaetocerotaceae.Tomas, C. R., Hasle G. R., Syvertsen, E. E., Steidinger, K. A., Tangen, K., Throndsen, J., Heimdal, B. R., (1997). ''Identifying Marine Phytoplankton'', Academic Press. There are more than 30 described species in genus ''Bacteriastrum'', but many of these are not currently accepted, and new species are still added to the genus.Sarno, D., Zingone, A. & Marino, D. (1997). ''Bacteriastrum parallelum'' sp. nov., a new diatom from the Gulf of Naples, and new observations on ''B. furcatum'' (Chaetocerotaceae, Bacillariophyta). Phycologia 36: 257-266 The type species for the genus is ''Bacteriastrum furcatum'' Shadbolt. Description ''Bacteriastrum'' is a widely distributed marine, planktonic genus. This genus is often associated with ''Chaetoceros'' but differs in radial symmetry and fenestration of setae. The colonies tend to lie in girdle view, and the cells are separated by the curvature of the basal part of the seta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Shadbolt
George Shadbolt (1817–1901) was a British writer, editor, student of optics and photographer with a strong interest in innovative techniques, who was active during the 1850s-1860s. Reported to have made the first microphotograph, he was also an early advocate of photographic enlargement, as well as compound and combination printing. Shadbolt's dislike of the glare of albumen printing paper led him to forsake it for salted paper. His technical interests probably motivated his praise of Henry Peach Robinson, whose combination prints were highly controversial. For seven years Shadbolt was editor of the publication that later became the ''British Journal of Photography''. One of his sons, Cecil V. Shadbolt, is remembered as a contributor to balloon photography. After 1864, Shadbolt's success as a mahogany dealer prompted him to retire from photography, although he maintained his professional affiliations. One of the founders of the Photographic Society of London (later the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diatoms
A diatom (Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of fres ...
