Exempel på hur man kan använda DIATOM i en mening

• A diatom (Neo-Latin diatoma) is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world.
• The fossils have been preserved because of the interaction of the volcanic ash from the nearby Thirtynine Mile volcanic field with diatoms in the lake, causing a diatom bloom.
• The major groups of algae are cyanobacteria, green algae, dinoflagellates, coccolithophores and diatom algae.
• However, reference conditions may also be established temporally by using preserved indicators such as diatom valves, macrophyte pollen, insect chitin and fish scales can be used to determine conditions prior to large scale human disturbance.
• In particular it has caused eutrophication and organic contamination of waters as interpreted from low diatom diversity and absence of pollution sensitive diatoms among other things.
• Some species of the foraminiferan genera Bulimina, Elphidium, Haynesina, Nonion, Nonionella, Nonionellina, Reophax, and Stainforthia sequester diatom chloroplasts.
• Didymosphenia geminata, commonly known as didymo or rock snot, is a species of diatom that produces nuisance growths in freshwater rivers and streams with consistently cold water temperatures and low nutrient levels.
• For example, there are diatom, coccolith, foraminifera, globigerina, pteropod, and radiolarian oozes.
• The main components of the sapropels are the dinoflagellate cysts, diatom algae, coccolithophorids, peridiniales.
• Germanium dioxide is used in algaculture as an inhibitor of unwanted diatom growth in algal cultures, since contamination with the comparatively fast-growing diatoms often inhibits the growth of or outcompetes the original algae strains.
• At least five endemic species, the most of any spring in the southwestern United States, are found exclusively in Montezuma Well: a diatom, the Montezuma Well springsnail, a water scorpion, the Hyalella montezuma amphipod, and the Motobdella montezuma leech.
• After maximal size has been reached, a new diatom with a rigid frustule, a so-called initial cell that is significally larger than its parent cells, is formed inside the auxospore which it eventually breaks free from.
• An example is the effect of the construction of the Aswan High dam in Egypt, where the drop in nutrient concentration to the Nile delta impeded the diatom blooms causing a substantial decrease the fish population of Sardinella aurita and Sardinella eba, while the reduced load of mud and silt affected the micro-benthic fauna leading to the decline of shrimp population.
• While larger chitons have been known to eat large algal blades, encrusting colonial animals, or even engage in predatory behavior to trap and consume mobile animals, Acanthochitona zelandica is a grazer and uses the radula to scrape algal films and built-up diatom layers off of tidal rocks.
• The frustule also contains many pores called areolae and slits that provide the diatom access to the external environment for processes such as waste removal and mucilage secretion.
• His diatom research largely dealt with species found in Denmark, Greenland, Iceland, Faeroe Islands and Jan Mayen.
• Diatomaceous oozes are predominantly formed of diatom skeletons and are typically found along continental margins in higher latitudes.
• The DCM tends to harbour more flagellated organisms and cryptophytes, whereas the epilimnion layer tends to have a larger centric diatom abundance.
• Navicula, a type of diatom, may locomote using a band of free-flowing mucilage strands, in the manner of a tracked vehicle.
• In 2004 Didymosphenia geminata, a diatom commonly known as didymo or rock snot, was discovered in New Zealand, the first time it was found in the Southern Hemisphere.
