HEMATOLOGIC VALUES OF CONDITIONED, CAPTIVE WILD COYOTES

REPRODUCTION IN CAPTIVE WILD-CAUGHT COYOTES (<i>CANIS LATRANS</i>)

Captive coyotes compared to their counterparts in the wild: does environmental enrichment help?

This article attempts to determine the effects of environment (captive or wild) and a simple form of environmental enrichment on the behavior and physiology of a nonhuman animal. Specifically, analyses first compared behavioral budgets and stereotypic behavior of captive coyotes (Canis latrans) in kennels and pens to their counterparts in the wild. Second, experiments examined the effect of a s...

A hematologic survey of captive waterfowl.

Hematologic parameters were studied in giant Canada geese (Branta canadensis maxima), mallard ducks (Anas platyrhynchos platyrhynchos) and various species of diving ducks at seasinal intervals throughout the year. Highest values for packed cell volume, hemoglobin content and erythrocyte counts were found in the winter and pre-nesting periods. Mean corpuscular volume and mean corpuscular hemoglo...

Positive reinforcement training affects hematologic and serum chemistry values in captive chimpanzees (Pan troglodytes).

Positive reinforcement training (PRT) techniques have received considerable attention for their stress reduction potential in the behavioral management of captive nonhuman primates. However, few published empirical studies have provided physiological data to support this position. To address this issue, PRT techniques were used to train chimpanzees (Pan troglodytes) to voluntarily present a leg...

Establishment of selected baseline blood chemistry and hematologic parameters in captive and wild-caught African white-backed vultures (Gyps africanus).

Despite the devastating collapse of three vulture populations on the Asian subcontinent as a result of their exposure to diclofenac, there is little available information on the normal physiology of many vulture species, including the African White-backed Vulture (Gyps africanus). Such information is needed to fully understand mechanisms for toxicity and to identify and prevent future health pr...
