Factors affecting the growth of Cladophora in relation to river pollution
Nuisance growths of Cladophora have been associated with eutrophication. A review of the literature, however, reveals a scarcity of relevant experimental growth studies. Sampling experimental streams reveals that the addition of sewage effluent to good quality water alters the flora from that …

The role of Cladophora glomerata as a habitat for bacterial communities and a reservoir of antibiotic resistance.
This thesis studied the filamentous alga Cladophora glomerata’s role in providing a refuge for antibiotic resistance and analyzed the community composition of the bacterial colonizers of C. glomerata mats by taking samples of water and C. glomerata mats from 4 sites along nearshore Lake Ontario and …

Trophic Dynamic Interactions in a Temperate Karst River
… Seasonal growth of the filamentous alga, Cladophora, is typically associated with nutrient-rich waters. This research compared macroinvertebrate food web structure between riverine reaches with contrasting underlying karst topography, nutrient levels, and Cladophora cover during summer …

Influences of a <i>Cladophora</i> Bloom on the Diets of <i>Amblema Plicata </i>and <i>Elliptio Dilatata</i> in the Upper Green River, Kentucky
… Attached macroalgae, including the genus <em>Cladophora</em>, may be the dominant primary producers in running water systems. <em>Cladophora</em>, however, has not yet been indicated as a prominent assimilated food source for freshwater mussels. The overall purpose of this study was to assess …

On the phylogenetic relationship of South African species of Cladophora (Chlorophyta) based on the 26S (LSU) gene region
In order to delineate the genus Cladophora in South Africa, several sites along the Cape peninsula were sampled and sequences for the partial26S region of the rRNA were obtained and a phylogram was constructed. The aims of this study were to provide a robust phylogenetic tree describing the …

Taxonomic and phylogenetic studies in the Cladophorophyceae (Chlorophyta)
… van twee afzonderlijke ordes, Siphonocladales en Cladophorales. Het voornaamste argument om alle genera in één orde te plaatsen is de klaarblijkelijke homogeniteit in chloroplastmorfologie, celwandstructuur en thallusbouw (coenocytisch). Anderzijds was de erkenning van twee afzonderlijke ordes …

Epiphytic Diatom Community Structure in a Karst Riverine System
… studied were Podostemum ceratophyllum and Cladophora. Percent cover of P. ceratophyllum and Cladophora were quantified in the four study reaches. The host species were sampled near-shore and mid-channel in each reach in September and October of 2013. After diatoms were extracted from the …

Long-term salinity trends in Zandvlei estuary and implications for dominant macroalgae
… 5, 10, 20, 29 ppt). Dominant macroalgae included Cladophora sp., Polysiphonia sp. and Enteromorpha prolifera. None of these algae survived at O ppt. In 1 ppt E. prolifera survived but growth was retarded, Polysiphonia sp. survived but did not grow and Cladophora sp. grew successfully at this …

In vitro culture studies of environmental factors and the effects of copper on a fouling alga, Cladophora glomerata (L) Kützing, which occurs in South African freshwater systems
The filamentous green macroalga, Cladophora glomerata (L.) Kütz., is problematic as a fouling organism in eutrophic freshwater systems in South Africa. A general consensus among scientific researchers is that C. glomerata thrives under high light conditions, temperatures between 15° C and 25° C, …

Bioaccumulation of Triclocarban, Triclosan, and Methyl-triclosan in a North Texas Wastewater Treatment Plant Receiving Stream and Effects of Triclosan on Algal Lipid Synthesis.
… using field samples mostly composed of the alga Cladophora sp. and the caged snail Helisoma trivolvis as test species. Additionally, TCS effects on E. coli and Arabidopsis have been shown to reduce fatty acid biosynthesis and total lipid content by inhibiting the trans-2 enoyl- ACP reductase. The …

FROM ALGAE BLOOMS TO INTERIOR SYSTEMS: SEAWEED-BASED MATERIAL SYSTEMS AND DIGITAL FABRICATION STRATEGIES FOR SUSTAINABLE ARCHITECTURE
… a material-driven design methodology. Waste Cladophora algae, together with oyster shell, alginate, and hemp fibers, are transformed into a biodegradable, low-carbon material. Digital fabrication techniques, including 3D printing and parametrically designed systems with mold casting, are used …

The ecology of algae in relation to river water equality surveillance
… carried out on the filamentous green alga Cladophora showed that this alga may have some value as a bioaccumulation indicator for metals, and as a bioassay organism for the assessment of the algal growth promoting potential of natural river waters.

The Study of Benthic Invertebrate Communities in: -(a) Lotic Eutrophic Waters (b) A River in Stages of Recovery from Past Pollution
… growths of algae and mosses and in particular Cladophora, which may subsequently drastically affect the oxygen/carbon dioxide balance of a watercourse diurnally. An apparatus was developed capable of delivering and controlling fluctuating oxygen levels in both time and intensity while other …

The Aquatic Ecology of Two Seasonal Marshes in Eastern South Dakota
… Floating vegetation, Lemna trisulca and Cladophora sp., became abundant in both marshes during the first week of June, and formed large thick mats by the end of June 1975. Daphnia pulex was the dominant zooplankter in Bothwell Marsh and made up 33% of the zooplankton density during the …

Development of biomaterials from sustainably produced macroalgae feedstocks
… a naturally co-existing mixed algae culture of Cladophora sp. and Rhizoclonium sp. The production and characterization of 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO)-oxidized Cellulose NanoFibre (CNF) from these macroalgae was accessed. Additionally, PHBV polymer biocomposite films …

Using algae as environmental impact indicators in urban freshwater ponds
… sites and soil erosion incidents. <i>Cladophora glomerata</i> (filamentous blanket weed) was the major algal species present in the ponds and was thus selected as the key indicator organism throughout the study. Due to the short pond retention times, planktonic microalgal populations …

Water Column Productivity, Calcite Precipitation, and Phosphorus Dynamics in Freshwater Marshes
… algae from the experimental marshes (major spp. Cladophora, Rhizoclonium, Hydrodictyon). Water, algal biomass and sediment samples were taken from June 1998 to May 1999. Saturation index values were always positive, showing that calcite precipitation was thermodynamically favored for both …

Spatial and temporal distribution of beach fouling in Saginaw Bay, Michigan
<p>Beach fouling is a problem in the Great Lakes. We surveyed beaches along the southwestern shore of Saginaw Bay to determine the spatial and temporal distribution of beach fouling (muck), muck composition, and any relationship between muck accrual and weather conditions. Muck deposition was …
