Size classes, population structure, growth, sex ratio, and size and age at maturity of Chionoecetes tanneri Rathbun (Brachyura:Majidae) off the Oregon coast

Creator:: Tester, Patricia A.
Abstract:: During eleven cruises conducted off the Oregon continental slope from April 1973 to March 1975, approximately 1600 specimens of the majid crab Chionoecetes tanneri Rathbun were collected. A time sequence of size frequency histograms and bivariate plots of allometric measurements were used to determine size classes, population structure, growth and...

Dynamics of crab larvae (Anomura, Brachyura) off the central Oregon coast, 1969-1971

Creator:: Lough, Robert Gregory, 1943-
Abstract:: Bimonthly plankton samples were collected from 1969 through 1971 along a transect off the central Oregon continental shelf (44° 39. l'N) to document the species of crab larvae present, their seasonality, and their onshore-offshore distribution in relation to seasonal changes in oceanographic conditions. A comprehensive key with plates is given...

The role of stridulation in the behavior of the shore crab Hemigrapsus oregonensis

Creator:: Guin, Marilyn P.
Abstract:: The claw shuddering display of the shore crab Hemigrapsus oregonensis was explored with acoustic and behavioral observations. Male H. oreqonensis stridulate during claw shuddering display. The stridulatory apparatus is present only on the males. The acoustic signal was of brief duration, showed a general pattern of sound bursts, but varied...

Evaluation of the sample ratio of sublegal to legal male crabs used to predict harvest of Dungeness crab (Cancer magister)

Creator:: Shaul, Warren
Abstract:: The sample ratio of sublegal to legal male crabs retained in crab pots was used in calculations to predict future harvest of Dungeness crabs, Cancer magister, along the Oregon coast. Accurate predictions by this method require a sample ratio representative of the population ratio. I sampled the Oregon Dungeness crab...

Population structure of the intertidal shore crab Hemigrapsus oregonensis (Brachyura, Grapsidae) in Yaquina Bay, a central Oregon coast estuary

Creator:: Batie, Robert Edward
Abstract:: The Hemigrapsus oregonensis population at Coquille Point in the Yaquina Bay Estuary on the Central Oregon Coast was studied from April, 1972 through May, 1973. The population was found to be vertically stratified from the 1 ft level to the 5 ft level. Population densities were found to be most...

Contribution of Farm Level Milk Sourcing on Non-Starter Lactic Acid Bacteria (NSLAB) in Cheddar, and the Assessment of High Resolution Melt Analysis used for Species Identification

Creator:: Baird, Christopher S.
Abstract:: Non-starter lactic acid bacteria (NSLAB) are found at low levels in fresh raw milk and are important to the dairy industry because of their potential impact on the flavor and texture of yogurt, sour cream, and cheese. The purpose of this study was to evaluate three methods for the identification...

Fescue taxonomy in the Pacific coast states

Creator:: Wilson, Barbara L.
Abstract:: Accurate taxonomy is essential to preservation and management of native grasses. Four problems in fescue taxonomy were investigated: the identity of the native fescue that dominates western Oregon and Washington prairies, the relationship of native Festuca roemeri to closely related grasses, the status of F. howellii and F. washingtonica, and...
