An Assessment Of Behavior Associated With Reproduction And Infant Caretaking In A Captive Family Group Of Saguinus Midas Midas, Melissa Elizabeth Martenson

Dissertations and Theses

The present study gathered both general and specific information about the behavior of a captive family group of Saguinus midas midas [red-handed tamarins] housed at the Washington Park Zoo, Portland, Oregon, USA. Saquinus midas midas is a rarely studied species, and detailed information about the behavior of this species is virtually nonexistent. For this reason, this study collected information about both activity budgets and social grouping within this family group.

The primary focus of this study was, however, the socialization of captive juvenile tamarins with respect to several behaviors relevant to reproductive success among the Callitrichidae. The behaviors assessed were: …

Effects Of Phenobarbital In Combination With Phenytoin Or Valproic Acid On The Delayed-Matching-To-Sample Performance Of Pigeons, Catherine Ann Karas

Masters Theses

The present study examined the effects of phenobarbital (S, 10,20, and 40 mg/kg), phenytoin (2.5, 5, 7.5, and 15 mg/kg), and valproic acid (40, 60, 80, and 120 mg/kg), and those of phenobarbital (10 and 20 mg/kg) in combination with phenytoin (2.5,5, and 7.5 mg/kg) or valproic acid (40, 60, and 80 mg/kg), on the delayed-matching-to-sample performance of pigeons. In general, high doses of each individual drug reduced accuracy. Drug combinations also reduced accuracy relative to control values. Reductions in accuracy produced by drug combinations were very similar in magnitude to those predicted by a response-addition model of drug interaction.
