Increased expression of GAPDH in cynomolgus monkeys with spontaneous cognitive decline and amyloidopathy reminiscent of an Alzheimer's‐type disease is reflected in the circulation
Previous studies of aging cynomolgus monkeys from our group identified spontaneous age‐associated cognitive declines associated with biomarkers and brain lesions reminiscent of Alzheimer's Disease (AD), in a proportion of aged monkeys. However, the molecular mechanisms that underlie the spontaneous amyloid disorders and cognitive declines observed in these affected monkeys have yet to be investigated in detail. Using reverse transcriptase quantit…
Does group size matter? Captive chimpanzee ( Pan troglodytes ) behavior as a function of group size and composition
The National Institutes of Health and the Association of Zoos and Aquariums recommend that captive chimpanzees be housed in multi-male, multi-female, age-diverse groups of no less than seven individuals. These recommendations are rooted in the idea that captive chimpanzee groups should be modeled after free-ranging, wild, fission-fusion chimpanzee societies. However, captive chimpanzees do not face the environmental pressures faced by wild chimpa…
Captive chimpanzee ( Pan troglodytes ) behavior as a function of space per animal and enclosure type
animal. Several studies have investigated chimpanzee behavior in relation to space per animal, but only two studies have examined these variables while attempting to hold environmental complexity constant. Both have found few, if any, significant differences in behavior associated with increased space per animal. The NIH does not provide recommendations pertaining to enclosure type. Although PrimadomesTM and corrals are considered acceptable FACE…
Delayed response task performance as a function of age in cynomolgus monkeys (Macaca fascicularis)
We compared delayed response task performance in young, middle-aged, and old cynomolgus monkeys using three memory tests that have been used with non-human primates. Eighteen cynomolgus monkeys--6 young (4-9 years), 6 middle-aged (10-19 years), and 6 old (above 20 years)--were tested. In general, the old monkeys scored significantly worse than did the animals in the two other age groups. Longer delays between stimulus presentation and response in…
Space use selectivity by chimpanzees and gorillas in an indoor–outdoor enclosure
Understanding the relationship between physical environments and nonhuman primate behavior is a key element for effective care and management in a range of settings. The physical features of the captive environment, including not only gross useable space but also environmental complexity, can have a significant influence on primate behavior and ultimately, animal welfare. But despite this connection, there remains relatively little conclusive dat…
Transfer and Acclimatization Effects on the Behavior of Two Species of African Great Ape (Pan troglodytes and Gorilla gorilla gorilla) Moved to a Novel and Naturalistic Zoo Environment
Ape behavior in two alternating environments
In many facilities, primates are voluntarily transferred between different enclosures on a daily basis to facilitate animal husbandry and exhibit maintenance. This procedure is particularly relevant in the management of great apes living in zoos, where the requirements of functional management must be balanced with the desire to maintain enriching and naturalistic exhibit enclosures that benefit ape residents and attract the visiting public. In t…
Hematological changes in vervet monkeys ( Chlorocebus aethiops ) during eight months' adaptation to captivity
This study investigated fluctuations in hematological values of 50 wild‐caught vervet monkeys (African green monkeys, grivets, Chlorocebus aethiops ) during habituation to captivity. The monkeys were categorized into four groups according to age and sex viz adult males, adult females, juvenile males, and juvenile females. The erythrocyte values were significantly higher ( P P
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 for an intramuscular (IM) injection of anesthetic.…
Use of primates in research
We assessed the use of nonhuman primates and nonhuman primate biological material in research by reviewing studies published in 2001 in peer‐reviewed journals. The number and species of primates used, the origin of the animals, the type of study, the area of research of the investigation, and the location at which the research was performed were tabulated. Additionally, factors related to the animals that may have affected the outcome of the expe…
An overview of surveys on how people view animal experimentation
Many factors may influence the outcome of surveys on how people view the use of animals in research. Some aspects are related to the instrument used, whereas others are related to the characteristics of the respondents. Conducted in Western countries, the study is primarily a review of 56 surveys targeting scientists, students, and the public. Surveys were obtained from searching online databases and reference lists, or directly from authors whos…
Influence of pet ownership on opinions towards the use of animals in biomedical research
The present study investigated the relationship between pet ownership and opinions on the use of animals in medical research. A questionnaire was answered by 484 schoolteacher students and 156 pre-school teacher students from Uppsala University, Sweden. Animal use was found to be of significant importance for developing treatments for human disease by 59 percent of respondents, but 15 percent did not agree. Forty-four percent thought that it was …
