Abstract Originally mesotrophic, the Bay of Quinte ecosystem has experienced eutrophication since the s, which resulted in the decline of once-lush submerged aquatic vegetation (SAV) beds in the upper bay by the by: Submerged Macrophytes in Lake Ontario: Current Knowledge, Importance, Threats to Stability, and Needed Studies Recovery after control of P loading has occurred in Irondequoit Bay but is delayed by turbidity in the Bay of Quinte. Cited by: Long-term field investigations in Oneida Lake in New York (Zhu et al., ) and Quinte Bay in Canada's Lake Ontario (Leisti et al., ) showed that submerged macrophytes grew deeper and more abundantly following the invasion of zebra mussels. The Bay of Quinte, a long, shallow, high-phosphorus system in Lake Ontario, spans a trophic range from eutrophic (upper Bay) to meso-oligotrophic (mouth). Phosphorus control (PC) and the invasion of dreissenid mussels and Cercopagis pengoi have .

Submerged macrophytes play a crucial role in shallow lakes due to the vegetation-turbidity feedback (Figure 1). They stabilize the clear, vegetation-dominated state due to the reduction of nutrient availability to phytoplankton, enhancement of top-down control of algae by providing refuge for zooplankton, suppression of phytoplankton by the excretion of allelopathic substances, facilitation of phytoplankton sedimentation, and prevention of sediment g: Bay of Quinte.

Meiliang Bay was the most heavily polluted bay in eutrophic Taihu Lake, and submerged macrophytes disappeared in most of sites in this Bay (Qin et al., , Ye et al., ). In this study, the growth inhibition of P. malaianus was mostly caused by Missing: Bay of Quinte. We are investigating possible metal contamination of submerged weed beds and marsh biota which may contribute to the low diversity and biomass of macrophyte beds and Typha marshes in the Bay. In , sediment, macrophytes and snails were sampled in wetlands close to the Moira River and at Hay Bay (part of the Bay of Quinte presumably unaffected by mine . Submerged macrophytes are uncommon in the swift-flowing upper section of the James River but become common to abundant during the summer and autumn throughout the Piedmont. About one-third of the river bottom in the Piedmont section was covered with submerged macrophytes during midsummer (Sprenkle et al. ). By far the most abundant species is grassleaf mudplaintain; other common species are sago pondweed, Illinois pondweed, American eelgrass Missing: Bay of Quinte.
