The role of luteinizing hormone-releasing hormone in the neuroendocrine control of seasonal reproduction in male rough-skinned newts, Taricha granulosa

Creator:: Zoeller, Robert T.
Abstract:: One hypothesis proposed to explain how the endocrine system controls reproductive cycles in seasonally breeding animals is that the hypothalamus undergoes seasonal changes in sensitivity to negative feedback by gonadal steroids. The result is seasonal changes in the secretion of luteinizing hormone-releasing hormone (LHRH) and gonadotropin secretion. The present experiments...

Reproductive biology and behavior of the brown tree snake (Boiga irregularis) on Guam.

Creator:: Waye, Heather L.
Abstract:: While there are many more species of reptiles in the tropics than in temperate latitudes, relatively little is known about the natural history of tropical species of snakes. Even basic information, such as reproductive ecology and behavior, is lacking. Patterns of reproduction in tropical species differ from patterns in temperate...

The ontogeny and mediation of sexual size dimorphism in the red-spotted garter snake, Thamnophis sirtalis concinnus

Creator:: Lerner, Darren T.
Abstract:: A wide range of environmental and physiological factors influence the type and extent of sexual dimorphism found in animals. Influential factors include variable climate, competition for resources and mates, mate choice, and parental investment. In addition, some investigators attribute differences in body size to physiological factors influenced by genetic and...

Chronobiology of garter snakes : environmental and hormonal mechanisms mediating hibernation and reproduction

Creator:: Lutterschmidt, Deborah I.
Abstract:: Most vertebrates exhibit seasonality in many life history traits. Such seasonal rhythms are temporally organized via the transduction of environmental cues (e.g., photoperiod, temperature) into appropriate endocrine signals. However, among ectothermic vertebrates that undergo continuous winter dormancy, temperature is the only environmental cue available for synchronizing seasonal rhythms. Most intriguing...

Morphological and endocrine correlates of dominance in male ring-necked pheasants (Phasianus colchicus)

Creator:: Lumas, Kathy A.
Abstract:: An investigation of the correlation between a number of behavioral, morphological and physiological parameters and dominance status of male Ring-necked Pheasants (Phasianus colchicus) was undertaken. Dominant males performed significantly more aggressive behaviors than subordinates and a higher proportion of these behaviors was directed toward distantly ranked subordinates. Animals could also...

The thermal regulation, microclimate, and distribution of the mountain beaver, Aplodontia rufa pacifica Merriam

Creator:: Johnson, Sheldon Robert
Abstract:: An investigation was undertaken to determine the role that temperature might play in limiting the distribution of the mountain beaver, Aplodontia rufa. A field study was carried on from August, 1965, through August, 1966, in the coast mountains of Benton County, Oregon, and consisted of measuring the annual temperature cycle...
