Ohio Lake Erie Protection Fund Final Report
Bacteria exhibit the ability to metabolize a wide array of contaminants and, as a result, reduce their toxicity to wildlife and humans. The general goal of this project was to design and evaluate, as a proof-of concept, a DNA microarray assay to evaluate bacterial detoxification mechanisms in contaminated sediments. The assay consists of 100 probes that measure activity of bacterial remediation...
متن کاملAtypical Tabularia in Coastal Lake Erie, USA
Tabularia populations collected at a coastal site in Lake Erie, near Cleveland, Ohio, USA exhibit highly abnormal morphology. Frustules may be bent, asymmetric, have irregular striae patterns, irregular margins, or any combination of these characters. The majority of specimens in the collection are abnormal to some degree. Although specimens are so atypical that identification is difficult, rel...
متن کاملRisk-benefit of consuming Lake Erie fish.
BACKGROUND Consumption of fish is promoted as a healthy way to obtain essential fatty acids (EFA) in the diet, yet the risk of ingesting harmful contaminants remains a concern. A recent study concluded that the risk-benefit of consuming fish from the North American Laurentian Great Lakes, which sustain important commercial and recreational fisheries, is currently unclear. We report the fatty ac...
متن کاملInterannual Variability of Cyanobacterial Blooms in Lake Erie
After a 20-year absence, severe cyanobacterial blooms have returned to Lake Erie in the last decade, in spite of negligible change in the annual load of total phosphorus (TP). Medium-spectral Resolution Imaging Spectrometer (MERIS) imagery was used to quantify intensity of the cyanobacterial bloom for each year from 2002 to 2011. The blooms peaked in August or later, yet correlate to discharge ...
متن کاملRecord-breaking Lake Erie hypoxia during 2012 drought.
Hypoxia has been observed in the central basin of Lake Erie for decades. To understand the impact of various controlling factors, we analyze a record of hypoxic extents for Lake Erie for 1985–2012 and develop a parsimonious model of their interannual variability. We find that the 2012 North American drought and accompanying low tributary discharge was associated with a record-breaking hypoxic e...
