Seasonal thermoregulation in the dark-eyed junco (Passeriformes: Junco hyemalis)

Creator:

Swanson, David Leslie

Abstract:

Winters in north-temperate climates impose high thermogenic demands upon small birds which are met by seasonal acclimatization. This thesis investigates the extent and mechanisms of seasonal acclimatization in darkeyed juncos (Junco hyemalis) inhabiting western Oregon. Although insulation is significantly increased in winter, acclimatization is primarily metabolic. Increased metabolism is required...

The histogenesis and mode of growth of the choroid plexuses of the hamster (Mesocricetus auratus)

Creator:

Dropp, John Jerome

Abstract:

The patterns of cell proliferation in the choroid plexuses of embryonic and post-natal hamsters were studied by means of auto-radiography (H³-thymidine). In addition, the PAS technique was used to determine the times of first appearance, relative amounts, location, and times of disappearance of glycogen free the plexuses. Many mitotic figures...
