Ascites production in the squirrel monkey (Saimiri sciureus)

Journal of Immunological Methods, 1981
A method is described for inducing the production of large amounts of ascitic fluid (AF) in the squirrel monkey Saimiri sciureus. The total amount of protein in the induced AF is close to 60% of that in the serum. Electrophoretic analysis of serum and AF samples from the same monkey revealed similar protein patterns, including gamma globulins. Antibody

Morphology of the Interorbital Region of Saimiri sciureus

Folia Primatologica, 1983
The skull of the platyrrhine primate Saimiri sciureus is distinguished by a large interorbital fenestra. Juvenile skulls still show a bony interorbital septum with some small gaps. A morphogenetic study was undertaken to better understand the structures of the interorbital region, which represents a linkage between the base of the braincase and the ...

Perception of chasing in squirrel monkeys (Saimiri sciureus)

Animal Cognition, 2015
Understanding the intentions of others is crucial in developing positive social relationships. Comparative human and non-human animal studies have addressed the phylogenetic origin of this ability. However, few studies have explored the importance of motion information in distinguishing others' intentions and goals in non-human primates.

Saimiri sciureus (Squirrel monkey)

1973
The karyotypes shown are a gift of Dr. T. C. Jones (New England Regional Primate Research Center, Southborough, Massachusetts) and were prepared from lymphocyte cultures. The two recognized phenotypes also differ in karyotype: the male came from Leticia (Colombia), and the female, from Iquitos (Peru).

Fertilization in vitro of Saimiri sciureus Follicular Oocytes

Journal of Medical Primatology, 1975
An in vitro fertilization system was developed for the squirrel monkey. Oocytes recovered from follicles of gonadotropin-treated females and cultured in vitro with spermatozoa resulted in fertilized ova capable of developing to the four-cell stage in culture.

Chromosomal Polymorphism and Somatic Segregation in Saimiri sciureus

Folia Primatologica, 1979
Quinacrine (Q) and Giemsa (G) banding, and sister chromatid exchange (SCE) studies have been carried out in Saimiri sciureus. In one male and one female studied, the diploid number was 2n = 44 and the karyotype corresponded to that described for the geographical region of Georgetown, Guyana.

The Thatcher illusion in squirrel monkeys (Saimiri sciureus)

Animal Cognition, 2012
Like humans, Old World monkeys are known to use configural face processing to distinguish among individuals. The ability to recognize an individual through the perception of subtle differences in the configuration of facial features plays an important role in social cognition.

Ureteral Reflux in the Squirrel Monkey (Saimiri sciureus)

American Journal of Veterinary Research, 1971
SUMMARY Twenty urinary samples obtained from 4 female squirrel monkeys (Saimiri sciureus) were measured. The volume of individual urinary samples ranged between 3 and 7.9 ml. (mean 4.415 ml. ± 1.45). Cystograms were prepared in 6 female squirrel monkeys to study ureteral reflux. Bilateral ureteral reflux was observed in 4 of 6 monkeys.

Renal Disease in Squirrel Monkeys (Saimiri sciureus)

Veterinary Pathology, 1981
Renal lithiasis, pyelonephritis, and glomerulonephritis were common in our colony of Brazilian phenotype squirrel monkeys (Saimiri sciureus), with glomerulonephritis being a major cause of mortality in adult animals. Squirrel monkey glomerulonephritis was divided into four major classifications, based on light and electron microscopy, similar to those ...

The contrast sensitivity of the squirrel monkey (Saimiri sciureus)

Vision Research, 1976
Abstract The contrast sensitivity of three squirrel monkeys and two human subjects was measured under similar conditions with a modified method of constant stimuli. Sensitivity was greatest for all subjects at 2–5c/deg and declined at higher and lower spatial frequencies.
