Samples were collected at weekly intervals during July-August and with less frequency in September, October and November (1970). Mean seasonal and range of concentrati...
متن کاملLong-Term Decline in Freshwater Mussels (Bivalvia: Unionidae) of the Western Basin of Lake Erie
Long-term trends in the abundance of unionids in the western basin of Lake Erie were examined from data collected at 17 stations in 1961, 1972, and 1982.

متن کاملWhat motivates farmers to apply phosphorus at the “right” time? Survey evidence from the Western Lake Erie Basin
250 words or less): Phosphorus loadings from the Maumee River watershed have significantly compromised the Lake Erie ecosystem, as evidenced by the most severe harmful algal bloom in Lake Erie in 2015 and the shut-down of Toledo drinking water supply in 2014. Despite government payments for adoption of voluntary conservation practices, excess nutrient runoff from agricultural production remains...
متن کاملInternal loading of phosphate in Lake Erie Central Basin.
After significant reductions in external phosphorus (P) loads, and subsequent water quality improvements in the early 1980s, the water quality of Lake Erie has declined considerably over the past decade. The frequency and magnitude of harmful algal blooms (primarily in the western basin) and the extent of hypoxic bottom waters in the central basin have increased. The decline in ecosystem health...
