where does red algae live  1 m s− 1), the exceptions being Lemanea and Paralemanea (e.g., Everitt and Burkholder, 1991; Vis et al., 1991; Filkin and Vis, 2004). Some algae can grow on rocks, soil or vegetation as long as there is enough moisture. Since red algae, and more conspicuously brown algae, have been shown to be extremely sensitive to changes of environmental factors, since the mid-1980s, the R/P index has also been used by a number of Mediterranean algologists as a synecological index to assess environmental conditions, if expressed as mean of values calculated for each sample from various phytobenthic communities present in a given area (community mean R/P value). The toxic dinoflagellate Pfisteria pisci-cida has caused concern recently. Israelson (1942) reported that most rhodophytes in Sweden were restricted to elevations less than 900 m above sea level. Live maerl has greater heterogeneity than dead maerl and the surface layer of maerl beds also provides a habitat and feeding area for functionally important epifauna and flora (Rees et al., 2010; Sheehan et al., 2015). Red algae have been found living in depths of over 500 feet. Nonetheless, most species are found in moderate flow regimes (mean 29-57 cm s− 1). More recently, in order to evaluate the ecological environmental conditions of small coastal areas, the use of a different index has been proposed, resulting from the ratio between the community mean R/P value for each community present in the surveyed area and the reference community mean R/P value of the corresponding communities. The toxins are remarkably stable once they enter drinking water and can be removed only by chlorination and activated charcoal. They also can survive at greater depths in the ocean than some other algae, because the phycoerythrin's absorption of blue light waves, which penetrate deeper than other light waves do, allows red algae to carry out photosynthesis at a greater depth. • Red algae are used as a food source while green algae are considered as potential bio-fuels.

They can have cellulose plates or armor covering their body (Fig. M. Cormaci, in Encyclopedia of Ecology, 2008. Many are found at great depths, living 210-260 meters below the surface of the ocean. Red slime algae is actually not a "true" algae at all; it is a bacteria that is technically known as cyanobacteria. For example, a study off the west coast of Scotland found that a single tow of three scallop dredges crushed and compacted maerl beds, and buried the maerl 8 cm below the sediment surface (Hall-Spencer and Moore, 2000).

Unicellular types are most common in lake plankton. Filamentous green algae are usually the most bothersome algae in nutrient-enriched streams, with massive populations observed in some cases. The red algae can live as deep as 260 meters in the ocean. The fungus keeps the algae protested from drying and gives some nutrients. The cyanobacterial toxins are known to affect food crop (bean) photosynthesis when they are present in irrigation water (Abe et al., 1996). Crustose corallines have been found in … Red algae are part of phylum rhodophyta, which is Greek for red plant. There are four thousand to six thousand species of red algae, and although some rhodophytes do inhabit freshwater (about fifty species), red algae are most common in tropical marine environments. The values obtained from this ratio have been grouped into five classes, as reported in Table 2. We use cookies to help provide and enhance our service and tailor content and ads. Twenty-five genera containing 40 species of cyanobacteria have been confirmed to have members that produce toxins (Codd, 1995; Carmichael, 1997). The Charophytes (stoneworts) are related closely to the Chlorophyceae but are more complex (Fig. Almost all algae live in or near water, fresh or salty. Often considered to be the evolutionary link between bacteria and algae, cyanobacteria are among the oldest forms of life on earth and date back at least 3.5 billion years. Chlorination of drinking water rich in organics may be problematic because it may form chlorinated hydrocarbons (known carcinogens). The algae are red because of their phycoerythrins, which impart a red hue. In large drainage basins, elevation and basin distribution patterns are interrelated; mean temperatures tend to increase from the source to the mouth, although the amplitude of diurnal fluctuations in temperature become less (Whitton, 1975). The neurotoxins are lethal at very low concentrations; the notorious toxin dioxin is 10–60 times less toxic than the cyanobacterial aphan-toxin (Kotak et al., 1993). The type species of Solenopora is a chaetetid sponge. Each class refers to a specific scale of assessment defining the ecological conditions of a given environment. Because of these factors they are generally found in the littoral zone (this includes the intertidal zone … FIGURE 8.6. Characteristics of Major Groups of Freshwater Algaea. Empower Her. The taxonomy of the group is contentious, and organization of the Coralline algae play an important role in the ecology of coral reefs. The key defining characteristic of diatoms is the silicon opalescent–glass cell wall called the frustule. Phycoerythrins are phycobilin pigments similar to those found in the cyanobacteria that allow red algae to use blue-green wavelengths of light. In North America, 26 genera are recognized in inland habitats (Chapter 5). Red algae are abundant in marine habitats but are relatively rare in freshwaters; in freshwaters, they usually inhabit lotic waterbodies. The action spectrum of collections from the canopied and open sites is similar and quite broad. The euglenoids have pigments similar to those of the green algae but are always unicellular and generally motile. These techniques have been used to show that acid precipitation is the result of industrialization and other important aspects of the history of lakes, such as fluctuation in salinity or trophic state. The Chrysophyceae are common in oligotrophic lakes as planktonic species. For example, the concentration of Compsopogon in warm waters can be explained by a maximum photosynthesis rate at 30-35 °C. Some of them have very little red pigment, therefore, they may appear bluish or green in color. These organisms are not necessarily closely related. Most varieties of algae live near the surface of the water in order to get enough sunlight to live. In contrast, C. caeruleus was present throughout the year and distribution was not related to temperature, but to current velocity in these Brazilian streams. To survive seaweeds need salty or brackish water, sunlight and a surface to attach themselves to. Temperature regime influences the latitude, elevation, drainage basin distribution, as well as seasonality of freshwater red algae (Sheath and Hambrook, 1990). Like other algae, green algae serve as an important food source for herbivorous marine life, such as fish, crustaceans, and gastropods, including sea snails.Humans use green algae as food, too. Characteristic features include a red photosensitive spot in one end and numerous chloroplasts in the cell (Fig. Chara can be abundant in the benthos of some oligotrophic lakes but may also be an important component of more productive wetlands. C, Coupin (1911), D, Atkinson (1905), E, Algen (1914)). There is concern that these compounds lead to increased rates of liver cancer (Carmichael, 1994). A common genus is Dinobryon (Fig. In the treatment of algal blooms in lakes, methods that lyse the cells and release toxins should be avoided (Lam and Prepas, 1997). Algae are plantlike organisms that use photosynthesis to produce their own food. A lot of red algae are introduced into the aquarium on live rocks. Coralline algae enter the aquarium in two ways, either they are already attached to the cured live rock, or they have to be seeded. Few taxa are typically localized at high current velocities (> 1 m s− 1), the exceptions being Lemanea and Paralemanea (e.g., Everitt and Burkholder, 1991; Vis et al., 1991; Filkin and Vis, 2004).
