Summary
Zoos aid conservation, but environmental mismatches cause health issues in captive primates. Scent enrichment, though understudied, shows promise for improving primate welfare and addressing these challenges.
Area of Science:
- Zoological studies
- Animal welfare science
- Primate conservation
Background:
- Zoos are vital for species conservation through breeding programs and reintroductions.
- Captive environments can cause stress, boredom, and health issues in zoo animals, impacting reproduction.
- Environmental enrichment is used to improve animal welfare, but sensory enrichment, particularly scent, is underutilized.
Purpose of the Study:
- To review the current understanding of scent-based enrichment for captive primates.
- To highlight the potential benefits of olfactory enrichment for primate welfare.
- To address the under-exploration of scent enrichment in zoological settings.
Main Methods:
- Literature review of studies on primate olfaction and enrichment.
- Analysis of existing research on sensory enrichment in zoos.
- Focus on scent-based interventions for captive primates.
Main Results:
- Evidence suggests olfaction plays a significant role in primate behavior and welfare, contrary to traditional views.
- Scent enrichment may positively impact the psychological and physiological well-being of captive primates.
- Further research is needed to fully understand and implement scent enrichment strategies.
Conclusions:
- Scent enrichment offers a promising, yet underutilized, avenue for enhancing the welfare of captive primates.
- Addressing the sensory needs of primates through olfaction can mitigate negative impacts of the captive environment.
- Increased research and application of scent enrichment are recommended for modern zoos.

Olfaction
44.5K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Physiology of Smell and Olfactory Pathway

Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
