A preliminary ecological survey of a temporary pond in a Douglas fir forest association with emphasis on the food and feeding habits of the Oregon newt, Triturus granulosus granulosus

Kelly, Robert W. 06 1900 (has links)
55 pages / This work has been done as a preliminary ecological survey of an aquatic habitat in a Douglas fir forest association. Since this is a preliminary study it is not expected to be complete in all details affecting the associations within a community. Little work of this type has been conducted previously, and much more work should be done along these lines in order to have a more complete understanding of the ecology of this, or a similar area. Perhaps this work will be of less value in itself than the assistance it may afford others who are beginning similar undertakings. In this work an attempt has been made to point out many of the physical factors which have an influence on, or directly affect the community, e.g., the size of the pond, the location, depth, etc. A descriptive account will be given of the flora and fauna, and an attempt has been made to present the interrelations between the organisms and their environment.
