Biomanipulation: a useful tool for freshwater wetland mitigation
1. Natural wetlands have traditionally been considered as efficient ‘ecological engineers’ for waste water treatment. However, the structure and function of many natural wetlands have been severely altered by the chronic exposure to pollutants, especially nutrients.

Development and use of a zooplankton index to monitor wetland quality in the Laurentian Great Lakes basin
Recent interest in biological monitoring as an ecosystem assessment tool has stimulated the development of a number of biotic indices designed to aid in the evaluation of ecosystem integrity; however, zooplankton have rarely been included in biomonitoring schemes. We developed a

Seasonal, interannual and spatial variability in the concentrations of total suspended solids in a degraded coastal wetland of Lake Ontario
A 4-year (1993 through 1996) monitoring program examined the distribution of total sus- pended solids (TSS) in Cootes Paradise Marsh, a shallow (mean depth of 70 cm), degraded, drowned- rivermouth marsh of Lake Ontario. Monthly meteorological and hydrographical data from 1986

Long-term response of the biotic community to fluctuating water levels and changes in water quality in Cootes Paradise Marsh, a degraded coastal wetland of L. Ontario
During the early 1900s, more than 90% of the surface area of Cootes Paradise Marsh was covered with emergent vegetation; currently, less than 15% of the surface is covered with aquatic vegetation and the remainder is wind-swept, turbid, open water. The loss of emergent cover is

A conceptual ecological model to aid restoration of Cootes Paradise Marsh, a degraded coastal wetland of L. Ontario, Canada
An ecological model is derived from recent studies, based on 60 years of empirical observations and experimental data, that conceptualizes how Cootes Paradise Marsh was transformed from a lush emergent marsh with considerable ecological diversity in all trophic levels, to one
