Role of hypothalamic biogenic amines in the release of luteinizing hormone in the ewe

Creator:: Wheaton, Jonathan Edward
Abstract:: The role of hypothalamic biogenic amines (norepinephrine, dopamine and serotonin) in regulating the release of luteinizing hormone (LH) in the ewe was investigated. Eleven experiments utilizing mature crossbred or Hampshire ewes were conducted to determine the ability of exogenous 17β-estradiol and various pharmacological agents to alter the levels of hypothalamic...

Vertical distribution patterns in a subarctic Pacific zooplankton community

Creator:: Marlowe, Christopher J.
Abstract:: A study has been made of the vertical distributions and migrations of a large number of zooplankton species at Weather Station "P" in the Subarctic Pacific. Simultaneously towed horizontal opening-closing nets were used for the study. The distributions and migrations of 104 taxa have been subjectively grouped into seven basic...

Cardiac and respiratory responses to hypoxia in the crab, Cancer magister (Dana)

Creator:: Stiffler, Daniel Francis
Abstract:: Heart rates and amplitudes were measured for both intact animals (in situ) and isolated hearts (in vitro) of the Dungeness crab, Cancer magister, exposed to low levels in oxygen. Recordings were also made of gill ventilation rate by measuring the frequency of scaphognathite (gill bailer) beats. Both the in vitro...

The Dover sole

Creator:: Demory, Robert
Abstract:: The Dover sole has been the most important flatfish in Oregon's trawl fishery since its beginning in 1938. At that time the fish was called slime sole, because the animal produces great quantities of the stuff. The term Dover sole apparently comes from the north Atlantic where a similar creature...

Cattle grazing habits and movements related to riparian habitats and forested ranges with inference to acute dietary bovine pulmonary emphysema (ADBPE)

Creator:: Roath, Leonard Roy
Abstract:: Grazing on the mountainous forested ranges of the Camp Creek Unit, Malhuer National Forest, was typified by irregular distribution of free-ranging cattle. A combination of management and physical, topographic constraints caused cattle to concentrate on the riparian zone early in the grazing season in 1977 and 1978. A large percentage...

Play behavior in the golden hamster

Creator:: Kreitlow, Jean Louise
Abstract:: Intensive observations were made of play behavior in the young hamster (Mesocricetus auratus) from 14 to 54 days of age. Behavior was recorded using movie film and a multi-channel event recorder. Play was first seen at 14 days of age. The amount of play increased rapidly thereafter, remaining relatively high...
