The Food Supply Of The Fish In The Great Lakes, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

When the early settlers made their homes along the shores of the Great Lakes, the waters of these inland seas teemed with fish. A cheap and apparently inexhaustible supply of food lay within easy reach, and they drew from it unstinted, nor was it strange that, with the increasing population and ever-widening means of communication, delicacies so tempting as the whitefish and lake trout were eagerly sought after in the markets of the neighboring cities, and that the ingenuity of generations of fishing folk was taxed to invent means of securing the fish-until finally, in the face of a growing …

Some Notes On The Biological Relations Of The Fish Parasites Of The Great Lakes, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

A pond or small lake furnishes few variations in depth, temperature, current, or food, and hence the life in it is comparatively uniform. Nowhere else in the world is there found such a continuous body of fresh water as in the Great Lakes. They afford, in themselves alone, an area of water one-fourth greater than that of the state of Nebraska; or, considering the streams and minor lakes within easy reach, no doubt the area is twice as great. Furthermore, there are found here conditions of temperature, depth, light and food more nearly like those prevailing in the ocean. As …

On The Parasites Of The Lake Fish: Notes On The Structure And Life History Of Distoma Opacum, N. Sp., Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

This work was done while a member of the scientific corps sent out by the Michigan Fish Commission to begin an investigation of the biological conditions in the Great Lakes. The work in 1893 was carried on at New Baltimore, on Lake St. Clair. My thanks are due to the Michigan Board of Fish Commissioners for the many conveniences placed at my disposal in carrying out the investigations on fish parasites, of which this is one result. To Professor J. E. Reighard, director of the party, I owe much for his interest and hearty cooperation in all matters pertaining to …

A Preliminary Report On The Worms (Mostly Parasitic) Collected In Lakes St. Clair, In The Summer Of 1893, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

In the work done on the fauna and flora of Lake St. Clair during the summer of 1893, the group of Vermes was entrusted to the writer. The following is submitted as a preliminary report on the ground covered, the material obtained, and the results of this branch of the work so far as they can be seen at this stage.

Excluding the Rotifera, which were studied by another member of the party, the Vermes are represented in fresh water by three great classes: the Plathelminthes (Flatworms), Nemathelminthes (Round or Threadworms), and the Annelida (Segmented-worms).

De Bestiis Marinis Or, The Beasts Of The Sea, Georg Wilhelm Steller

Zea E-Books in American Studies

Steller’s classic work, published in Latin in 1751 and in German in 1753, contains the only scientific description from life of the Steller’s sea cow (Hydrodamalis gigas), as well as the first scientific descriptions of the fur seal or “sea bear” (Callorhinus ursinus), Steller’s sea lion (Eumetopias jubatus), and the sea otter (Enhydra lutris).

Steller’s sea cow was a sirenian, or manatee, inhabiting the North Pacific Ocean and Bering Sea. It was first discovered by Europeans in 1741 and rendered extinct by 1768. It was a 30-foot long, plant-eating aquatic mammal, weighing …
