Ranunculus L. is an early diverging clade in the Angiosperm phylogeny. The split between terrestrial and aquatic/semi-aquatic lineages within the genus occurred within 20 Ma (Emadzade and Horandl, 2011), which is much younger than for some well-known aquatic lineages such as Ceratophyllum and Potamogeton. Ranunculus sceleratus Linn. is a semi-aquatic plant commonly found in paddy fields, stream...

Gu, B. and M.V. Hoyer. 2005. Community structure and environmental conditions in Florida shallow lakes dominated by submerged aquatic vegetation. Lake and Reserv. Manage. 21(4):403-410. Florida inland waters are dominated by shallow lakes, many of which support the growth of submerged aquatic vegetation (SAV). We examined the species composition and selected environmental variables of SAV-domin...

Although aquatic macrophytes have been used individually for wastewater remediation, there is a dearth of studies comparing their efficiency level to determine the most effective remediation specific heavy metals. This study aimed macrophyte amongst Eichhornia crassipes, Pistia stratiotes, Nymphaea nouchalli, Lemna minor and Ceratophyllum demersum Cr Cd from effluents in Yenagoa Metropolis, Nig...

Arsenic (As) pollution is a serious concern worldwide. Recent studies under environmentally relevant conditions revealed that, in the aquatic plant Ceratophyllum demersum, pigments are the first observable target of toxicity, prior to any effect on photosynthetic parameters or to oxidative stress. Lethal toxicity was initiated by a change of As species and their distribution pattern in various ...

Aquatic and terrestrial plants and microorganisms were screened to test their ability to remove the herbicide, atrazine, from the environment. Plants included hornwort (Ceratophyllum demersum), switchgrass (Panicum virgatum), reed canarygrass (Phalarius arundinacea), annual ryegrass (Lolium multiflorum), and two varieties ofperennial ryegrass (Lolium perenne). Microorganisms studied included a ...

Nebraska Public Power District (NPPD) began monitoring aquatic-macrophyte production in Lake Ogallala, Nebraska, in 1989 because the lake provides cooling water for a coal-fired electricity generating facility-Gerald Gentleman Station (GGS). Large mats of macrophytes in the cooling water caused several trips of the generating units at GGS, at considerable cost to NPPD. The plants also support m...

Spatial information of the dominant species of submerged aquatic vegetation (SAV) is essential for restoration projects in eutrophic lakes, especially eutrophic Taihu Lake, China. Mapping the distribution of SAV species is very challenging and difficult using only multispectral satellite remote sensing. In this study, we proposed an approach to map the distribution of seven dominant species of ...

An efficient DNA isolation protocol specifically modified to get pure quality DNA required for molecular studieshas been reported in this paper. Some aquatic plants (Potamogeton spp., Ceratophyllum demersum and Myriophyllum spicatum) were used for the study. The protocol developed will be useful in getting high and pure DNA. Instead of using the available DNA extraction kits, this protocol can ...
