Editing Squirrel monkey (section)

=== Osmoregulation ===
Squirrel monkeys are subject to both high temperatures and high humidity in their natural habitat. The humidity can range from 70% saturation in the 'dry' season up to 90% in the 'wet' season. Squirrel monkeys are able to tolerate up to 75% humidity with small adjustments in behavior and physiology that increase in significance as the humidity goes up. When reaching approximately 95% humidity, the monkeys have more drastic changes in osmoregulation in order to maintain homeostasis. As evaporative water loss decreases at these high levels of saturation, the monkeys will take in less water and create a more concentrated urine in order to maintain proper ion and water levels inside the body.<ref name=":5">{{Cite journal|last=Holmes|first=W.N|date=1986|title=The effect of relative humidity on osmoregulation in the squirrel monkey (Saimiri sciureus)|journal=Primates|volume=27|issue=4|pages=465–470|doi=10.1007/BF02381891|s2cid=12458596}}</ref>
