Eugene F. Stoermer
Eugene F. Stoermer (March 7, 1934February 17, 2012) was a leading researcher in diatoms, with a special emphasis on freshwater species of the North American Great Lakes. He was a professor of biology at the University of Michigan School of Natural Resources and Environment. Biography His Bachelor of Science degree was obtained in 1958 and his Doctor of Science in 1963, both from Iowa State University. His doctoral thesis was "Post-pleistocene diatoms from Lake West Okoboji, Iowa" Stoermer originally coined and used the term ''Anthropocene'' from the early 1980s to refer to the impact and evidence for the effects of human activity on the planet earth. The word was not used in general culture until it was popularized in 2000 by Nobel Prize-winning Atmospheric chemistry, atmospheric chemist Paul Crutzen and others who regard the influence of human behavior on Earth's atmosphere in recent centuries as so significant as to constitute a new geological epoch. He is the co-author with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Surirella Stoermerii
''Surirella'' is a genus of diatoms in the family Surirellaceae. The genus was circumscribed by Pierre Jean François Turpin in Mem. Mus. Hist. Nat. vol.16 on page 361 in 1828. The genus name of ''Surirella'' is in honour of Jacques Simon Armand Suriray (1769–1846), who was a French doctor, naturalist and botanist (Algology), Zoologist, who worked in Le Havre.

Pinnularia Stoermeri
''Pinnularia'' is a genus of fresh water algae, more specifically a type of diatom. Habitat ''Pinnularia'' is a predominantly fresh-water algae usually found in ponds and moist soil. They can also be found in springs, estuaries, sediments, and oceans. Members of this genus are most commonly found in of water, at . External structure ''Pinnularia'' are elongated elliptical unicellular organisms. Their cell walls are composed chiefly of pectic substances on a rigid silica framework, and composed of two halves called thecae (or less formally, valves). These halves overlap like a Petri dish and its cover, the outer larger valve called Epitheca and the smaller called hypotheca. The margins of the two thecae are covered by a connecting band called a cingulum and all together are referred to as a frustule, and the whole cell is covered by a mucilaginous layer. The surface view is called valve view and band view is called girdle view. Internal structure The cytoplasm is arranged a ...

Navicula Stoermeri
''Navicula'' is a genus of boat-shaped diatom algae, comprising over 1,200 species. ''Navicula'' is Latin for "small ship", and also a term in English for a boat-shaped incense-holder. Diatoms — eukaryotic, primarily aquatic, single-celled photosynthetic organisms — play an important role in global ecology, producing about a quarter of all the oxygen within Earth's biosphere, often serving as foundational organisms, or keystone species in the food chain of many environments where they provide a staple for the diets of many aquatic species. Mobility ''Navicula'' diatoms have been observed to possess a motile ability to glide over one another and on hard surfaces such as microscope slides. Around the outside of the navicula's shell is a girdle of mucilage strands that can flow and thus act as a tank track. File:Navicula tripunctata 2.jpg, ''Navicula tripunctata''type species In zoological nomenclature, a type species (''species typica'') is the species name with w ...
