Sea lampreys in the Great Lakes of North America

The movement of sea lampreys into the upper Great Lakes (Superior, Michigan, and Huron) initiated a series of biological changes which have extended beyond the fish directly attacked by the parasite. The threat posed by the sea lamprey was not generally recognized until it was well established in all the lakes and had seriously affected the fisheries in Lakes Huron and Michigan. As the...

Survival and development of lake herring (Coregonus artedii) eggs at various incubation temperatures

Lake herring eggs stripped and fertilized from a local stock were incubated in a constant-flow incubator at constant temperatures ranging from 0 to 12.1° C. Rate of development, percentage survival, percentage of abnormal and normal hatching, and length of fry at hatching were determined. The average incubation time from fertilization to 50% hatch varied from 37 days at 9.9-10.3° C to...

Palynology of the Cretaceous-Tertiary boundary in the northern Rocky Mountain and Mississippi Embayment regions

In both the Rocky Mountain and the Mississippi Embayment regions it is often difficult to distinguish Upper Cretaceous from lower Tertiary rocks on the basis of physical characteristics; the transition can be recognized with relative ease, however, on the basis of abrupt qualitative changes in plant microfossils. Many Cretaceous species vanish and new species appear in the Paleocene. In...
