Final answer:
Monkeys under stress due to social disruptions, including being separated from their owners and familiar environments, can have their immune response compromised. Studies by Harlow and others show the importance of social relationships and comfort for primate well-being and health outcomes.
Step-by-step explanation:
Regarding Alan's concern about leaving his pet monkey at a pet hotel while he travels, it is important to consider the research on social disruptions and immunity in primates. Given the evidence from various studies, option c is the most accurate: yes, monkeys under stress due to social disruptions have weakened immune systems.
Research by Harlow and colleagues has highlighted the critical nature of social comfort over sustenance for young rhesus monkeys, indicating the profound impact of social relationships on primate well-being.
Furthermore, work by neuroscientists like Robert Sapolsky and Carol Shively demonstrates that social hierarchy and stress can predict health outcomes in non-human primates. Stressful experiences, especially chronic stress, are known to suppress both innate and adaptive immune responses, potentially leading to increased disease susceptibility.
Therefore, if the pet hotel can provide a stable and comfortable environment, it can minimize the stress associated with Alan's absence and its potential negative impact on the monkey's immunity.
