A biological and taxonomic study of selected myxosporida of some Oregon fresh-water fishes

Creator:: Wyatt, Ellis Junior
Abstract:: Biological studies were conducted on a histozoic myxosporidan Myxobolus insidiosus (Wyatt and Pratt, 1963) from the musculature of Oncorhynchus tshawytscha (Walbaum). This organism is known to occur in spring chinook salmon in Oregon and coho salmon O. kisutch (Walbaum) in Washington. In addition Myxobolus kisutchi (Yasutake and Wood, 1957) was...

A capture-recapture analysis of a mountain beaver population in western Oregon

Creator:: Lovejoy, Bill Pertl
Abstract:: This report summarizes the results of a field study of a population of the Pacific mountain beaver, Aplodontia rufa pacifica, from August 1965 through August 1967. The study site consisted of a 13. 5- acre grid on a logged over area in the Coast Range Mountains of Benton County, Oregon....

A combined study of the growth of the grayling (Thymallus arcticus) and the development of its olfactory apparatus

A comparative analysis of morphological, physiological, and biochemical adaptation to abiotic stress in intertidal porcelain crabs, genus Petrolisthes

Creator:: Stillman, Jonathon Harris
Abstract:: Organismal tolerance to abiotic environmental stresses contributes significantly to setting the distribution limits of organisms, as demonstrated by vertical zonation patterns in the marine intertidal zone. In this thesis, the ultimate (evolutionary) and proximate (mechanistic) causes of tolerance to temperature and emersion stresses associated with the intertidal zone were examined...

A comparative study of prenatal behavior ontogeny in altricial and precocial murid rodents

Creator:: Robinson, Scott R., 1952-
Abstract:: Using techniques that permit the direct observation of fetuses in vivo, prenatal behavioral development was compared among four species in the rodent family Muridae: the Norway rat (Rattus norvegicus), Mongolian gerbil (Meriones unguiculatus), cotton rat (Sigmodon hispidus), and spiny mouse (Acomys cahirinus). Rattus and Meriones bear altricial offspring, as do...

A comparative study of the chromosomes from five species of the genus Rana

Creator:: Haertel, John David
Abstract:: The karyotypes of five species of ranid frogs were determined from metaphase plates of bone marrow cells. The colchicine, hypotonic- citrate, blaze-dry technique was used to obtain the plates. Morphometric datawere obtained from the karyotypes and compared with other species of the genus Rana. Like most other members of the...

A dietary and morphometric analysis of sceloporine (Iguanidae) lizard populations

Creator:: White, Robert Lewis, II
Abstract:: Analyses of sympatric and allopatric populations of Sceloporus occidentalis and S. graciosus from central Oregon indicate a high degree of similarity in diet. Relative abundance, the equivalent number of equally common taxa (E), and the probability of similarity (SIMI) were used in the analyses. Shifts in diet between populations of...
