In order to determine the contribution of aquatic macrophyte communities on nutrition to sustain the high primary productivity of an estuary aquatic community, we analyzed the process of phosphorus release from sediments in aquatic macrophyte community in the estuary of the Chikugogawa River, South-Western Japan. Vertical profile of 4 PO concentration and redox potential (Eh) of pore water in...
A tier III, essential fish habitat analysis was used to evaluate the biochemical condition of common mummichog Fundulus heteroclitus residing in two isolated tidal salt marshes, one a relatively undisturbed polyhaline site dominated by Spartina alterniflora and the other a mesooligohaline site dominated by an invasive variety of Phragmites australis. Stable isotopes signatures of C, N, and S in...
Geographic patterns in leaf stoichiometry reflect plant adaptations to environments. Leaf stoichiometry variations along environmental gradients have been extensively studied among terrestrial plants, but little has been known about intraspecific leaf stoichiometry, especially for wetland plants. Here we analyzed the dataset of leaf N and P of a cosmopolitan wetland species, Phragmites australi...
In order to further the development of plant-based remediation of sites contaminated by carbo-chemical and petro-chemical industries, the penetration of the roots of Phragmites australis in contaminated soil substrate was studied in model trials. The series of experiments contained model substrate with firm bitumen and tar. In terms of the level of root penetration, the roots and rhizomes penet...
