	Desmid eaters - desmids in the food web.
		Yet, desmids have been shown to be a potential food source for zooplankters like cladocera (water fleas) and copepods.
		Despite the fact that planktonic desmids are a good potential food source, in practice, because of their low population density, they use to play but a minor role in the pelagial food web (at least in temperate climatic regions, for in the tropics the situation is possibly different).
		Incidentally, cells of desmid species are encountered which are tightly enclosed by a transparent, sharply bordered envelope, about one micrometer in thickness and showing no external sculpture.

	Desmid of the month - May 2003 -
		is a colonial, filamentous desmid, rather commonly occurring in all kinds of standing freshwaters, provided that those are not too acid/oligotrophic.
		Moreover, cells join each other across almost their total breadth so that it looks as if we are dealing with a true (parenchymatic) filament rather than with a filamentous colony.
		In the upper cells a slight median constriction (sinus) is to be seen.

	Desmid
		Desmids are green algae, comprising around 40 genera and more than 10000 species, found mostly but not exclusively in freshwater.
		Desmids assume a variety of highly symmetrical and generally attractive shapes, which provide the basis for their classification.
		The desmids are sometimes treated as members of the Zygnematales, but more often given the separate order Desmidiales.

	Desmid (Site not responding. Last check: 2007-10-29)
		Desmids are highly diverse unicellular green algae that are primary producers in fresh water ecosystems (Coesel 1996), are consumed by microfauna (Brook and Ells 1987), and can serve as biological indicators of the biological health of fresh water bodies (Coesel 1992).
		Desmids are cosmopolitan microorganisms of tropical to arctic water bodies (Brook and Williamson 1983; Da Graca and De Moraes 1996).
		This taxonomic study documents desmid genera, species, and subspecies found in 17 alpine lakes in Colombia and establishes a basis for further evaluation of highland aquatic ecosystems in South America.

		Desmids are fresh water algae found in ponds, swamps, and marshes around the world.
		Seldom are two identical desmids found, because their bodies grow in a wide variety shapes and sizes.
		Desmids reproduce by division at the nucleus, resulting in the formation of two very similar daughter cells that contain the same DNA but have slightly differing body shapes.

		Desmid Diversity : On the left, Netrium, a representative of the homogeneous walled Mesotaeniaceae group of desmids.
		Desmids are primarily found in freshwater habitats, such as ponds, rivers, and lakes.
		Growing desmid cells therefore have only a single set of chromosomes, and the zygote is the only diploid cell in the life cycle.

		Desmids are typically said to occur mostly in acidic waters, e.g.
		Research has shown however, that the most divers desmid communities are found in neutral waters and in the Netherlands strong negative effects of acidification on desmid communities have been found.

		Desmids are a diverse subgroup consisting of 3 orders: Desmidaceae, Gonatozygonaceae, and Mesotaeniaceae.
		Desmid species are characterized by a division of each cell into 2 hemicells, each typically containing a single chloroplast.
		Desmids include filamentous and colonial forms in addition to unicells and bicells.

		In order to study possible adaptation in phosphorus (P) uptake kinetics and growth response, we cultured two desmid species under two different, fluctuating P regimes.
		The two desmid species, Staurastrum chaetoceras and Cosmarium abbreviatum, originated from trophically different alkaline lakes and have been well characterized in their growth kinetic parameters under continuous P limitation (chapter 3).
		For both desmid species a significant adaptation in cell size to the P supply regimes examined could be measured with both Coulter counter and microscope.
