Sneezing Behavior in the Squirrel Monkey and Its Biological Significance

Urine washing in brown capuchin monkeys (Cebus apella): Testing social and nonsocial hypotheses

“…Alternatively, UW in conjunction with direct sun might enhance the thermoregulatory effect of UW. The finding of increased UW rates with high air temperatures is concordant with temperature effects on UW in S. sciureus, reported by Schwartz and Rosenblum (1985). However, it remains to be demonstrated experimentally that UW regulates body temperature in C .…”

Urine Washing and Sniffing in Wild White-faced Capuchins (Cebus capucinus): Testing Functional Hypotheses

“…Further experimental work on captive individuals is needed, and a new approach should be employed to test functional hypotheses for UW in the wild. Manipulation of climatic conditions, as in Schwartz and Rosenblum's (1985) study of Saimiri, would be a compelling test of the thermoregulatory hypothesis. Previous experimental manipulations used to test social hypotheses for UW have included presenting Saimiri with urine marks made by conspecifics (Candland et al, 1980) and exposing Cebus apella to mirrors (Roeder and Anderson, 1991).…”

“…Further, the studies by Roeder and Anderson (1991) and Carosi et al (2004) incorporated direct measurements of air temperature. Most convincingly, Schwartz and Rosenblum (1985) experimentally manipulated temperature and humidity and found that higher temperatures, whether accompanied by lower humidity or not, increased UW rates in Saimiri. Not all available evidence accords with the thermoregulation hypothesis, however.…”

Factors Affecting Urine Washing Behavior in Tufted Capuchins (Cebus apella)

“…Studying captive Cebus apella, both Roeder and Anderson (1991) and Carosi and Rosofsky (1999) reported that rates of urine washing increased under conditions of higher ambient temperature, consistent with a thermoregulatory function, whereas Miller et al (2008) observed no such relation. Schwartz and Rosenblum (1985) provided experimental evidence that higher temperatures caused an increase in the rate of urine washing in Saimiri sciureus.…”
