Variations in salinity tolerance in the Pacific Treefrog, Hyla regilla, in Oregon

Creator:: Roberts, James Oliver
Abstract:: Eggs, larvae and adults of the four subspecies of Hy la regilla occurring in Oregon as given by Jameson, Mackey and Richmond (1966) were collected and subjected to salt stress in a series of graded seawaters. It was found that in all cases adults were more tolerant than larvae and...

Morphological variations in populations of Lacerta from islands in the Adriatic Sea

Creator:: Clover, Robert C.
Abstract:: Phenetic relationships in insular populations of Lacerta sicula and L. melisellensis correspond to geologic ages of the islands in two regions of the Adriatic Sea. Populations of L. melisellensis on older islands are more similar to populations of L. sicula than are L. melisellensis from younger islands, and examination of...

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...

Aspects of the autecology of the plethodontid salamander, Aneides ferreus (Cope)

Creator:: McKenzie, Donald Samuel
Abstract:: Laboratory experiments and simulated field conditions were utilized to gain a better understanding of the ecology of the clouded salamander. Animals collected in western Oregon were utilized for studies in habitat selection, where it was shown that there was a significant pattern of selection of litter types (rock, bark, and...

Small mammal micro- and macrohabitat selection in streamside ecosystems

Creator:: Doyle, Arlene T.
Abstract:: During summer and fall of 1981 to 1983, mark-recapture was conducted in riparian and upland habitats within old-growth and mature forests in the Cascade Range of Oregon. Number of individuals and species richness were greater in riparian than upland habitat. For most species, the mean adult weights and the percentages...

A study of behavior in the deer mouse Peromyscus maniculatus rubidus Osgood during its 24-hour cycle of activity in a simulated natural habitat

Creator:: Laban, Cornelis
Abstract:: With a growing emphasis on details of behavior comes an increasing need for knowledge of natural behavior patterns. Studies on the life history of Peromyscus maniculatus have long been available in the literature. More recently, investigators have turned to analyzing the behavior of some of the subspecies of P.m. in...

The respiratory ecology of the rough-skinned newt Taricha granulosa (Skilton)

Creator:: Smith, John Martin
Abstract:: An investigation was undertaken to determine if respiratory changes might occur in conjunction with migrations of the rough-skinned newt, Taricha granulosa (Skilton) in and out of ponds in the Willamette Valley. A field study was carried on from December 1964 through October 1965 to investigate certain physical and chemical parameters...

The behavioral ecology of larval and neotonic northwestern salamanders (Ambystoma gracile)

Creator:: Taylor, James Thomas
Abstract:: In the summers of 1973, 1974 and 1975, I investigated population age structure and density, and behaviors relating to habitat selection, predator avoidance and intraspecific interaction in a population of northwestern salamanders in a lake in the Oregon Cascade Mountains. The study was carried out by skin- and scuba-diving at...

Investigation of the circadian rhythm of locomotion in the rough-skinned newt, Taricha granulosa

Creator:: Briggs, Jeffrey Lawrence
Abstract:: Over 56,000 hours of locomotor activity of Taricha granulosa were recorded using two types of low cylindrical plastic monitoring chambers. This species shows distinct rhythms of activity under normal day-night cycles, shortened day-night cycles, constant darkness (DD) and constant light (LL). The rough-skinned newt is day active and crepuscular. I...
