Squirrel Monkey Communication

1985
Communication in the squirrel monkey, Saimiri sciureus has been the subject of numerous analyses over the past two decades. One of the interesting aspects of having participated in some of these studies has been the realization that, even in this well-studied species, there are significant gaps in understanding the functional significance, ontogeny ...

Cytokine secretion in squirrel monkeys

Psychoneuroendocrinology, 1997
The squirrel monkey, a non-human New World primate, has several endocrine peculiarities, including a 10-fold higher plasma cortisol concentration than Old World primates, such as man. Glucocorticoids are known to have immunomodulatory properties. We therefore measured cytokine levels in supernatants of in vitro cultures of mononuclear cells from the ...

Sociophysiology of squirrel monkeys

American Journal of Primatology, 1991
AbstractPrimate sociophysiology is an emerging discipline concerned with understanding the proximate mechanisms that contribute to the generation and maintenance of species‐typical social systems. Studies of squirrel monkeys illustrate that sociophysiological processes are more varied than is commonly assumed with respect to both the effective social ...

Nocturnal sleep in squirrel monkeys

Electroencephalography and Clinical Neurophysiology, 1974
Abstract The nocturnal sleep records of three squirrel monkeys over 12 h sessions were examined for 7 consecutive nights. The sleep records were described in terms of the percentage of time in each of the stages of Awake. Stages 1.2.3 4 and REM. The mean percent time spent in sleep was 82.4″ ″ of the recording period.

Composition of Squirrel Monkey Milk

Folia Primatologica, 1972
The gross composition of normal squirrel monkey milk was (in g/100 ml): lipids, 5.1; crude protein (N × 6.38), 3.5; lactose, 6.3; and ash, 0.3. The lipids, proteins, and ash were further characterized. This milk had many similarities to milk from other primates, and was intermediate in total protein and lactose concentration between milks from Old ...

The Squirrel Monkey Stabil1metry

Acta Oto-Laryngologica, 1982
In order to characterize postural ataxia associated with peripheral vestibular lesions, we have developed a T-perch recording system suitable for squirrel monkeys (tree-living primates). This system includes strain gauges for detecting movement of the vertical shaft in the directions of anterior-posterior and left-right.

Squirrel monkey

1992
Abstract Thorington (1985) classified animals in the genus Saimiri into two species; Saimiri sciureus, of which he proposed there are four subspecies: S.s.sciureus, S.s. cassiguarensis, S.s. boliviensis, and S.s. oerstedii, and S. madeirae. However, research on the taxonomy of Saimiri is continuing (for example, Van de Berg et al. 1987).

Intraprostatic spermatozoa in the squirrel monkey

The Prostate, 1988
AbstractThe recent observation of spermatozoa within the human prostate prompted this study to determine if spermatozoa were present in prostates of nonhuman primates. Six of 32 squirrel monkey prostates contained intraglandular spermatozoa. No associated pathologic lesions were found. Spermiophages were seen in one case.
