Townsend's mole, Scapanus townsendii (Bachman), was
studied by live trapping, dead trapping, and observation
from July 1961, to July 1963, in Tillamook County,
Oregon. This study was initiated at the request of Tillamook County farmers to determine biological facts that
would assist them in their efforts to control this small...
The existence of eigenvalues is shown for certain types of
integral equations with continuous kernels, the proofs utilizing some
basic results of collectively compact operator approximation theory.
Settlement of structures built on geologically recent compressible alluvium is a common cause of concern during design. Total settlement results from a combination of: 1) initial elastic settlement, 2) primary consolidation, and 3) secondary compression. The reliability of prediction of total settlement is affected by an understanding of these components...
Home range, dispersal, homing and density of Townsend's mole, Scapanus townsendii (Bachman), were studied during 1964 near Tillamook, Oregon. Additional information on the success of marking
and capture techniques and the response of moles to flooding was gathered. This study was initiated to supply information which might aid in the...
Six hundred and forty nutrias, Myocastor coypus (Molina), were collected near Corvallis, Oregon, and examined to determine criteria of their growth and reproduction. Two hundred and eighty-nine
were tagged, measured, and released to determine growth under natural conditions. Nutria weights were calculated to the nearest 0.1 pound by weighing the...
