is cosmarium a desmid

SEM picture of C. granatum. Examples of functional groups of some representative planktic green algae along with their tolerances and sensitivities. In these environments, night-time convection is stronger than in temperate lakes, and the low resistance form helps these organisms in optimizing their traveling into the water column and in the exploitation of nutrient and light resources. Grazing fishes (central and largescale stonerollers) are also numerous, but most fishes are invertivorous (darters and small cyprinids) or piscivorous (bass). Oedogonium, details of parietal reticulate chloroplast illustrated in upper cell; cells separated by apical caps. Taeniopteryx, Strophopterx, and Neoperla are abundant stoneflies. Or in other words, Desmid, (order Desmidiales), order of single-celled (sometimes filamentous or colonial) microscopic green algae. The Gasconade River is part of the Central Prairie freshwater ecoregion (Abell et al. Digital Image Collection of Desmids. Figure 28. There has been recent concern about a toxic golden alga (Prymnesium parvum) in reservoirs of the Brazos Basin. Thus it is possible, more so than in other algal groups, to assess which species occur solely on tepuis in contrast to those occurring across the region or throughout the continent. Actually, the higher water temperatures experienced by tropical lakes as compared to temperate ones decreases the density of the water. Its main characteristic is the outline of the semicells, viz. This variety is mainly distinguished by the open sinuses; it can also have produced basal angles but this feature in not always apparent ... D.B. Coloured scanning electron micrograph (SEM) of placoderm desmid (Cosmarium botrytis). Figure 16. It is difficult to make generalizations about the morphological diversity that is exhibited wihin the genus. For this study samples were collected randomly from 12 different habitat around the district during January 2018 to April 2019. Meridion, valve view. Notice short, blunt spines. Several microalgal species such as Chlorella, Scenedesmus, Desmodesmus, Neochloris, Chlamydomonas, Nitzschia, and Cosmarium have been applied to various types of wastewater treatments coupled with biofuel production under sterilized or nonsterilized conditions. Arctic grayling are common throughout the drainage. (1986) collected epilithic periphyton samples from the Avan River, a tributary of the Noatak River. The BNR is probably the least disturbed major tributary within the Ozark Highlands freshwater ecoregion (Abell et al. Thus, optimizing sinking enhances the physiological adaptations of these algae in relation to the different physical and chemical conditions of the water column. Unicellular desmid with two rounded semicells separated by an isthmus or constriction. Dominant genera of mussels are Lampsilis (6 species), Quadrula (3 species), and Fusconaia (2 species). Nova Hedwigia, 36 : 733 - 757 * Bicudo, C. E. M. 1969. Each connecting strand is made up of two overlapping parts, one that originates from the pore group on one cell and the other from a similar pore group on the adjacent cell of the colony (Gerrath, 1970). Green algal assemblages, both benthic and planktic, well integrate physical, chemical, and biological parameters of freshwater ecosystems. Information on benthic macroinvertebrates is limited, but data (to order or family) are available from 13 lotic sites in August (Childers and Kernodle 1981). 1981. ; s: individual or colony surface; v: individual or colony volume; m: individual or colony maximal linear dimension. True flies such as chironomid midges do not appear as abundant in the BNR as in other rivers. It is possible to verify that those species characterized by elongated, needle shape (e.g., Closterium aciculare) will be positioned by their morphological traits in the vicinity of the R corner; those showing spherical shape and small dimensions (e.g., picoplankton) will tend to accumulate in the vicinity of the C corner and those with a larger spherical (e.g., Pseudosphaerocystis spp. Figure 73. Hyalella azteca is a more abundant amphipod in the river. or cf. Larger green algae include both swimming, flagellated forms and nonmotile ones, whose existence is linked to the degree of entrainment into the circulation movements occurring in the water column (Figure 4). Prev. The species list in Tables 5.1–5.4, however, might suggest a different conclusion. Another cell of C. granatum with a more gradual transition between basal and polar part of the semicell. One of the most successful functional classification, addressed toward an ordering of all phytoplankton taxa, distributed green algae in nine ecological groups (Table 1). Manuwal (1974), in a short-term survey of the birds of the Noatak drainage, lists 18 species of birds with a habitat affinity for “fluvatile waters,” including loons, ducks, five species of shorebirds, and gulls. Still, compared to animals and vascular plants, we still know very little about desmid and diatom diversity and distribution in the New World. Figure 5. 2000) and is characterized by a rich and diverse flora and fauna. Collection was by squeezing submerged plant material or using a plankton net. It seems important to underline that the modification of sinking velocity allowed by the form resistance factor is not a way to merely reduce sinking and in some cases it can increase the velocity itself and favor sinking. or slightly ellipsoidal shape (e.g., Eremosphaera tanganykae) will concentrate around the S corner. Mayflies followed a similar pattern, with the families Baetidae and Heptageniidae found at nearly every site, and mayflies often composed a considerable portion (25% to 50%) of the fauna. Figure 55. Figure 51. 2000). Encyonema colony. However, diatoms peak in late winter to early spring as silica levels are depleted, and they are replaced in summer by a broad spectrum of algae, especially greens and cyanobacteria. DAVID L. GALAT, ... ROBERT G. WHITE, in Rivers of North America, 2005. Diploneis. Zygospores were encountered but a few times. : Mougeotia sp. Thus the typical desmid cell consists of … pyramidate with a truncate apex. Various groups (thiol, phosphate, amino, and carboxyl) present in the cell walls of microbes adhere to the dye molecules; this process of binding is often quick enough to be completed in a few hours (Chen et al., 2016; Qin et al., 2014). Craneflies (Diptera: Tipulidae) were found at most sites but in low abundance. In this method, the first anaerobic process has been used to treat textile effluents with high chemical oxygen demand, while the second one has been used for the resulting effluents with relatively low chemical oxygen demand (Xiang et al., 2016). Their response time is rapid, as is recovery time, with recolonization after a disturbance often more rapid than for other organisms. Figure 33. Based on morphological comparisons with previous studies, S. venezuelana is not necessarily endemic to tepuis but may occur in other types of aerial habitats in the Neotropics (Golubić, 1967). The ecological limitations of high-latitude running waters—low food supply, severe hydrothermal regime (Oswood 1997), and barriers to dispersal—constitute a selective “filter” (Poff 1997), so that the fish fauna of Alaska in general and northern Alaska in particular is a highly selective subset of the North American fish fauna (Oswood et al. Cosmarium abbreviatiforme (top view, empty cell) Cosmarium abbreviatum. The Buffalo is an excellent smallmouth bass stream, but fishermen who use small lures or baits must catch far more of the colorful longear sunfish than smallmouth bass because they outnumber them more than 10 to 1. In addition, these enzymes are extracellular, so they do not require preconditioning of white-rot fungus with the pollutants. This ordination well approximates the results obtained by dividing the algae according to their morphological descriptors. Large woody debris is scarce in the Buffalo, as in most Ozark streams. true desmids (Cosmarium, Micrasterias, e.g. Although the physical, chemical, and biological elements of the Buffalo National River have been fairly extensively surveyed and reported in governmental agency reports and publications, almost no studies of ecosystem processes (primary/secondary production, metabolism, food web analyses, trophic dynamics, etc.) Nonnative plants include Japanese honeysuckle, multiflora rose, loblolly pine, mimosa, and fescue, but none are very abundant near the river. Usually, the lateral sides are subparallel or even slightly divergent at their base, then they abruptly converge towards the apex. Most species occur in the Cyprinidae (29), Catostomidae and Percidae (14), Centrarchidae (12), and Ictaluridae (8). triquetra, and Cosmarium itatiayae f. minor, though only the Micrasterias appears to be formally designated by Förster, and the Cosmarium does not appear in the Index Nominum Algarum at all. Figure 70. Five species of crayfishes are in the basin, but >99% of crayfish composition is within the genus Orconectes. Filamentous blue-green algae lacking specialized cells: a. Oscillatoria, b. Lyngbya, c. Schizothrix. Four taxa (Actinotaenium riethii, Closterium pseudocostatum, Cosmarium discrepans and C. hostensiense) are newly described and the name of one taxon (Cosmarium lenzenwegeri) is recombined. These can only be inferred from the survey data, studies in the other tributaries of the White River, and studies of other streams in the Ozark Plateaus. Over 66 species of fishes occur in the Buffalo National River (Becker and Kilambi 1975, Kilambi and Becker 1977). For example, it provides surface for attachment of epiphytic algae that are grazed by aquatic snails, including Elimia potosiensis. Scrapers and collectors are the most abundant functional feeding groups. In several cases, a formal circumscription would require more material than is available—the organism may be rare at the sampled localities, or the material is in poor condition and resampling is not possible. Navicula colony. 1991). Methods – Samples were collected from Lake Bangweulu and adjacent swamps as well as from Lake Wakawaka. Tabellaria. Two varieties of Micrasterias arcuata found on Roraima and Churí (var. Figure 22. Figure 35. They thus could provide a powerful monitoring tool, once the processes governing their relative importance are fully understood. Recently, three strains of cyanobacteria (Anabaena flos-aquae UTCC64, Phormidium autumnale UTEX1580, and Synechococcus sp. Stauroneis. This is one of the few desmid genera that is considered to be colonial. Nannochloropsis gaditana efficiently removes N and P, being useful for wastewater treatment (Ledda et al., 2015). Gomphoneis. Sampling from various locations in the basin has yielded 52 families of aquatic insects. Desmids may be one of the best groups, alongside diatoms, to examine algal endemism on tepuis because their great morphological diversity allows fairly reliable species-level identification.

Chimarra, Cheumatopsyche, Hydropsyche, Psychomyia, and Helicopsyche dominate the caddisflies. In this communication the authors recorded 15 taxa belonging to the 3 genera viz. The federally endangered pink mucket is present in the main-stem Gasconade. leaf These features and geographical isolation would have been responsible for high levels of endemism in macroorganisms. Joseph F. Gerrath, in Freshwater Algae of North America, 2003. Actually, they contain a high number of species, making data useful for statistical and numerical applications to assess water quality. Zygospore of C. granatum. From Greek cosmarion, "small ornament". In biodegradation, biologically mediated breakdown of organic compounds occurs; if complete biodegradation occurs, the process is called mineralization. In routine practices, the anoxic method has commonly been employed. ARTHUR V. BROWN, ... W. KEVIN PIERSON, in Rivers of North America, 2005. During wet season, larger specimens are gradually selected by copepods' grazing pressure on smaller ones. C. granatum is a rather small to moderately large-sized species belonging to the group of smooth-walled Cosmaria. The bluestripe darter is endemic to the Gasconade and nearby Osage River basins and is globally listed as imperiled (G2). Rhizoclonium. Detailed analysis of the list of observed cyanobacteria shows that out of 67 taxa, 30 are identified to the species level (including four newly described species from Pantepui), 32 have an identification on the generic level (sp. jonsonii, the shape and dimensions of akinetes are needed, which were never observed in the tepui material. The most widely distributed cyprinids are bleeding shiner, horneyhead chub, largescale stoneroller, and central stoneroller. 209 Pictures in this folder. This golden alga is usually found in estuaries, but it now has been found in numerous inland water bodies throughout Texas. Nitzschia. Cosmarium abbreviatiforme . The physical structure of the plants, which occur in dense stands, provide preferred habitat for many macroinvertebrate and fish taxa, both predators and prey. Brachysira. Moreover, very dynamic environments support a large diversity of different sizes and shapes of species either present in the assemblages or as propagules ‘ready to develop’ as the environmental template changes. This may be regarded as an attempt performed by a population to counteract adverse environmental conditions or, more correctly, as a mechanism that tend to select those specimens bearing morphological characteristics that best fit the environmental template. Planothidium: a. rapheless-valve and b. raphe-valve. Asiatic clams have been introduced into the main-stem Gasconade. Five families dominate the rich fish fauna (105 species) of the Gasconade River. Seven mussels of state conservation concern (S1) reside in the upper basin: scale shell (also G2), elephantear, spectaclecase, elktoe, black sand shell, bullhead (also G3), and Ouachita kidneyshell. 1995). Crayfishes are opportunistic feeders that generally prefer macroinvertebrates for food. Gravel bars are colonized by black willow, Ward's willow, witchhazel, and, nearer the water, smartweed, water willow, and rushes. If we follow the theory of moderate endemism, which in contrast to ubiquity theories allows for approximately one third of microbe species to have restricted distributions (Foissner, 2006, 2008), we should expect a high level of endemism in the microbial realm too. Beetles include Dubiraphia, Psephenus, and Stenelmis. SEM picture of C. granatum in more detail showing scattered cell wall pores. Spondylosium. Pinnularia. Vaucheria, a siphonaceous green Chrysophyte. By using this method, the morphological traits distribute the algae into a triangular portion of the Cartesian plane, whose vertices represent three different environmental conditions in relation to nutrients and light availability (Figure 5). C. granatum is a rather small to moderately large-sized species belonging to the group of smooth-walled Cosmaria. ; Scequa: Scenedesmus quadricauda; Vol sp. Some basic characters: end view often compressed, absence of spines, apex of cell neither cleft nor indented, cells solitary. The rhizomes and roots stabilize substrates. The semi-cells may have a somewhat triangular or trapezoidal outline with a bumpy surface. The two semicells are rounded in front view and flattened, oval, or elliptic in side view. Cocconeis: a. raphe-valve and b. rapheless-valve. Figure 10. ; Chla sp. The first data on the distribution of desmids in Serbia date back to 1883 and from then on until 2009 altogether 630 different taxa were identified. In 1982, a salmon hatchery (Sikusuliaq Springs) was constructed on the lower Noatak River, rearing chum salmon fry. Chum salmon are the only salmon taken in quantity from the rivers of northwestern Alaska (O'Brien and Huggins 1974). Trees on floodplain alluvium include Shumard's oak, bur oak, and box elder, and in seldom-flooded locations, sugar maple, black walnut, and bitternut hickory. ; Cloaci: Closterium aciculare; Dic: Dictyospaherium sp. The cells are deeply divided in the middle by a short isthmus that contains the nucleus. Macroinvertebrates are not very abundant in the BNR but are just as diverse as other tributaries of the White River. Figure 72. Placoderm desmids are in the suborder Closteriinae, comprising Closterium, Gonatozygon and Penium, and in the suborder Desmidiinae, Actinotaenium, Cosmarium, Cosmocladium, Euastrum, Micrasterias, Staurastrum, Staurodesmus, and Xanthidium. Meridion colony. The fish fauna of the Noatak River is dominated by the family Salmonidae, including whitefish, grayling, trout, and salmon. Rhoicosphenia: a. girdle view and b. valve view. A globally imperiled (G2) stonefly, Acroneuria ozarkensis, is recorded only in the Gasconade River basin and a few other streams in the United States. (2016). Water willow is the dominant vascular plant at the water's edge on gravel bars. B. Cosmarium is a unicellular desmid which consists of two round semicells separated by a constriction. Mollusca are also common in the Buffalo but are not as numerous as in the Lower White (Gordon 1982). Among the many varieties that have been described there are several ones that may be confused with similarly looking species. The selection of microalgae for a particular treatment option can be based on the knowledge about the indigenous species in such wastewaters, making use of their characteristics for our advantage. Figure 4. Notice in this cell also an abrupt transition at the lateral sides between the slightly divergent basal parts and the strongly converging polar parts. The Noatak River belongs in the Yukon ecoregion, the largest freshwater ecoregion in North America, incorporating most of Alaska and the Yukon Territory (Abell et al. tropicus was previously identified in Mississippi, Java, Sumatra, and New Zealand. Figure 43. Neidium. In Methods in Stream Ecology (Second Edition), 2007. Although the Noatak Valley is home to the full range of the Alaskan megafauna—grizzly bear, wolf, caribou, moose, wolverine—truly lotic vertebrates (other than fishes) appear to be very limited. Moderately eutrophic lakes and ponds very often show an amazingly high diversity of green algae. C–S–R strategic ordination of some selected green algae performed according to morphological traits. Cylindrocystis; Mesotaenium; Netrium Ulothrix. Primary production is limited by low nutrient concentrations. Water willow is an abundant aquatic macrophyte in the Buffalo River. Figure 61. Figure 50. Hydrurus. Spines increase the greatest axial linear dimension (GALD) of these organisms and thus reduce the probability to be eaten by planktic herbivores. This is one of the few desmid genera that is considered to be colonial. Ten Gasconade basin fishes are of conservation concern in Missouri (S1–S3), including the southern cavefish. Mekapogu Madakka, ... Muni Ramanna Gari Subhosh Chandra, in Recent Developments in Applied Microbiology and Biochemistry, 2019. Hannaea. Dragonflies (Hagenius, Macromia, Neurocordulia, Gomphus) and damselflies (Enallagma, Hetaerina, Argia, Lestes) are diverse but not numerous. Mammalian river specialists are limited to the river otter in the lower river. : Monoraphidium sp. Cosmariumis a single-celled placoderm desmid. Synedra. Jan Kaštovský, ... Teresa Vegas-Vilarrúbia, in Biodiversity of Pantepui, 2019. Gyrosigma. Figure 46. a. Stephanocyclus, b. Discostella. In addition, since they represent an important source of nutrition for the zooplankton, they also have to counteract the grazing pressure exerted by these ‘herbivores.’. Another challenge when considering endemism on tepuis is the general paucity of phycological floristic studies in the Neotropics. Abundant odonates include Argia, Erpetogomphus, and Gomphus. Cymbella. goyazense, Cosmarium pentachondrum, and Sphaerozosma luetzelburgianum appear to be restricted to Brazil and were found on Churí-tepui. Approximately 357km of the Gasconade and Big Piney rivers were recommended for designation as “scenic” or “recreational” under the National Wild and Scenic Rivers Act due to their outstanding natural resource and aesthetic values; however, such designation never occurred. Figure 49. On the basis of the mechanism of degradation of textile dyes, the degradation method can be further divided into biosorption and biodegradation (Kaushik & Malik, 2009). Northern Ozark streams appear to be primarily nitrogen limited based on nutrient enrichment studies conducted during low flow periods (Lohman et al. In apical view elliptical. Desmidium from a. front and b. back views. The attention paid by plankton ecologists to the size and shapes of these algae has its origin in the need to categorize them not only on the basis of their phylogenetics, still subject to massive reappraisal, but also on the functional basis of their roles in aquatic ecosystems.
