| Notes | The author compared populations of a small freshwater snail in four streams in the Oregon Coast Range, including the Yaquina River near Eddyville, and Salmon Creek, a tributary of the Yaquina River. Samples were taken in each study area every three months. Stream order (from mainstem to branches) was important. The snails reproduced less in larger streams, perhaps due to a parasite. While reproduction was higher in smaller branches, so was mortality. This thesis gives a look at a part of stream ecology less often studied. Schematic drawings of stream reaches are included. Major professor was John H. Lyford, Jr. |
