The purpose of this review is to highlight key developments in nematode ecology from its beginnings to where it stands today as a discipline within nematology. Emerging areas of research appear to be driven by crop production constraints, environmental health concerns, and advances in technology. In contrast to past ecological studies which mainly focused on management of plant-parasitic nematodes, current studies reflect differential sensitivity of nematode faunae. These differences, identified in both aquatic and terrestrial environments include response to stressors, environmental conditions, and management practices. Methodological advances will continue to influence the role nematodes have in addressing the nature of …

Lake Andes sits at the center of the Yankton Sioux Reservation in south-central South Dakota and might be described as a prairie pothole, except it encompasses nearly 5,000 acres when full of water, stretching twelve miles long by a mile to a mile and a half wide in a quasi-crescent shape. Originally carved out by a receding glacier during the Wisconsin glaciations, for its entire history the lake has gone dry during low precipitation -- a cycle interrupted after the Bureau of Indian Affairs (BIA) commissioned several artesian wells beginning in 1896. As the lake expanded, the U.S. Fish Commission …
