1 Determining the mechanisms by which invasive species exclude natives is critical for conserving and restoring native populations in impacted habitats. In recent decades the grass Phragmites australis has been aggressively invading coastal marshes of North America, with monocultures often replacing diverse assemblages of plants. 2 Our objective was to quantify how P. australis modifies the abi...

Th ere have been several reports of symbionts in the roots of plants that live in aquatic environments. Arbuscular mycorrhizal fungi (AMF) are the most common microsymbionts and possibly recolonized the aquatic environment together with plants; however, their functions and the extent of their benefi ts are unclear. Furthermore, the presence of other groups of fungi, such as dark septate fungi (...

A total 20 species belonging to 14 families and 18 genus were reported for their ethnomedicinaly uses. Alkaloids, Glycoside, terpenoid, steroid, flavonoids, tannins, saponins and phtobumins distribution in twenty ethnomedicinaly important hydrophytes and marsh plants belonging to 14 different families were assessed and compared. Most of the plant found to contains alkaloid, glycoside, steroid a...

Laboratory expenments were conducted to evaluate the effects of increased so11 salinity on gas exchange functlonlng and growth of the braclush-marsh grass Spartlna patens (Alt) Muhl under controlled soil redox potentials (Eh) which were malntalned at either aerobic (+489 mV) or hypoxlc (-40 mV) conditions Plants were subjected to salinities of 0 5, 15 and 25 ppt gradually over a 7 d penod and l...

background: celiac disease (cd) has been found in up to 10% of the patients presenting with unexplained abnormal liver function tests (lft). as there is no precise data from our country in this regard, we investigated the prevalence of cd in patients presenting with abnormal lft. methods: from 2003 to 2008, we measured iga anti-tissue transglutaminase (t-tg) antibody (with elisa technique) with...

The low pH of naturally acidic aquatic environments is the result of soft-water with low buffering capacity and high concentrations of natural organic acids. Our current understanding of the influence of pH on aquatic organisms is largely limited to laboratory studies conducted under controlled conditions with little incorporation of these organic acids. Recent studies suggest natural organic a...

le tI. Annual sweetcJover (Melilotus segetalis (Brot.) Ser. plants from the Guadalquivir salt marsh (S.W. of Spain) were grown in a glasshouse, on sandy soil with nutrient solution and four salt treatments (O, 10, ot 50 and 100 mM NaC!). Plants (five replicates per treatment and age) were harvested at 50, 90 and 120 ,1. days after germinatíon. Sodium, chloride and potassium were determined for ...

The environmental DNA (eDNA) method has increasingly been recognized as a powerful tool for monitoring aquatic animal species; however, its application for monitoring aquatic plants is limited. To evaluate eDNA analysis for estimating the distribution of aquatic plants, we compared its estimated distributions with eDNA analysis, visual observation, and past distribution records for the submerge...
