Creator:: Greene, Michael John
Abstract:: In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...

Abstract:: Pheromones are chemical cues produced by organisms that affect the behavior and/or physiology of conspecifics. The orchestration of reproductive behaviors in many animals depends on the expression of sex pheromones. In insects, intraspecific variation in sex pheromone expression is commonly observed and often influences social interactions between individuals. To what...

An analysis of vocalizations of the rufous-sided towhee Pipilo erythrophthalmus oregonus (Bell)

Creator:: Beltz, Joan Dunkel
Abstract:: The purpose of this study was to record on tape and to analyze the sonagrams of the complete repertoire of the vocalizations of the Rufous-sided Towhee, Pipilo erythrophthalmus oregonus. Meanings were assigned to a number of the calls. Sounds of nestlings, juveniles, and vocalizations connected with parental care were not...

Abstract:: The ecology of a population of snowshoe hares, Lepus americanus washingtonii, was studied in western Oregon from 1960 to 1962. Objectives were to obtain information to control hares, which frequently cause damage to coniferous reproduction in the region, and to compare the life history of this little-studied subspecies with others....

Creator:: Mac Phail, Laurie Ann
Abstract:: Chromosome maps were made of Drosophila gibberosa salivary gland and fat body chromosomes, and the puffing patterns were compared in the two tissues for selected times in development. The times were early third instar (E), late third instar (0, at pupariation (0 hr), at two hours (2 hr), four hours...
