behaviour of the dilution characteristics of the coastal waters off tuticorin is presented in thebackground of setting up of a desalination plant. simulations of dispersion and spreading of the proposeddischarges has been carried out. scenarios of dilutions were assessed based on the results of a 2d model using the advection-dispersion theory. it is observed that under prevailing currents in th...

This paper focuses on the advances made in taxonomical distribution and environmental studies plant diversity Ghogha Coastal area of district Bhavnagar state Gujarat. The Gujarat is quantitatively qualitatively rich as it has large number families, genera species. Total 54 species recorded selected under study comprised three subclasses polypetalae, gamopetalae monochlamydae. Subclass polypetal...

WHIGHAM, D. F., and RICHARDSON, C. J. 1988. Soil and plant chemistry of an Atlantic white cedar wetland on the Inner Coastal Plain of Maryland. Can. J. Bot. 66: 568-576. Atlantic white cedar (Chamaecyparis thyoides (L.) BSP.) wetlands are widely distributed along the Atlantic coast, yet there is very little information on their nutrient dynamics. In this paper we present data on the chemical co...

The number and abundance of exotic weeds in native forest fragments are known to correlate with the distance to the nearest large town. This is of concern as land near lowland forest is increasingly being subdivided for housing throughout much of New Zealand. We quantified the relationship between settlements and exotic plants for the coastal forests in eastern Northland, New Zealand. Exotic pl...

Invasive plants may compete with native plants by increasing the pressure of native consumers, a mechanism known as "apparent competition." Apparent competition can be as strong as or stronger than direct competition, but the role of apparent competition has rarely been examined in biological invasions. We used four years of demographic data and seed-removal experiments to determine if introduc...

Seagrass meadows, one of the world's most important and productive coastal habitats, are threatened by a range of anthropogenic actions. Burial of seagrass plants due to coastal activities is one important anthropogenic pressure leading to the decline of local populations. In our study, we assessed the response of eelgrass Zostera marina to sediment burial from physiological, morphological, and...

Climate change is projected to increase stress for many coastal plant communities. Along large portions of the North American coast, habitat degradation from anthropogenic changes to the environment already threaten the community structure of tidal marshes and submerged aquatic grass beds. The potential loss of ecological services historically provided by these communities has been a long-stand...

Salt marshes are among the most abundant, fertile, and accessible coastal habitats on earth, and they provide more ecosystem services to coastal populations than any other environment. Since the Middle Ages, humans have manipulated salt marshes at a grand scale, altering species composition, distribution, and ecosystem function. Here, we review historic and contemporary human activities in mars...

Rivers of the Coastal Plain of the southeastern United States are characteristically low-gradient meandering systems that develop broad floodplains subjected to frequent and prolonged flooding. These floodplains support a relatively unique forested wetland (Bottomland Hardwoods), which have received considerable ecological study, but distinctly less hydrogeomorphic study. The hydroperiod, or an...
