Calcium Content of the Western Basin of Lake Erie
Water samples from the western basin of Lake Erie were filtered to restrain suspended particles larger than 4 /xm and were analyzed for copper, iron, zinc, manganese, magnesium, and calcium by atomic absorption spectrophotometry. 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. The mean number of unionids at these stations declined over this time period, decreasing from 10 m~2 in 1961, to 6 m~2 in 1972, down to 4 m~2 in 1982. This decline in abundance was reflected in the decrease in the number of stations where muss...

15 صفحه اولWhat 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 کاملThe Sarcoplasmic Reticulum of Striated Muscle of a Cyclopoid Copepod
The fine structure of the abdominal musculature of the copepod Macrocyclops albidus was investigated by electron microscopy. Tubules penetrate into the muscle fibers from the sarcolemma, continuity between the wall of the tubules and the sarcolemma being clear. A dense network of tubules envelops the myofibrils, its interstices being occupied by cisternal elements. At the Z lines the tubules tr...
