Preserving wildlife and its biodiversity is one of the top priorities for supporting the ecosystem and maintaining its balance. In light of climate change and the steady rise in temperatures, a research group from the University of Michigan in the United States wanted to study the impact of rising temperatures on the immunity of wild capuchin monkeys.
The journal "Science Advances" published a study on November 29, 2024, revealing the detrimental effects of high temperatures on the immune performance of those monkeys, particularly the young ones.
In Costa Rica
The researchers conducted their study on capuchin monkeys in the Taboga Forest Reserve in Costa Rica, Central America. These monkeys are characterized by their adaptability and ability to live in different climates and environments. Therefore, we chose them for the study.
The researchers collected the monkeys' urine to measure the amount of neopterin in the urine, which is an indicator of immune system performance. The researchers documented the temperatures the monkeys experienced in the days and weeks preceding the urine collection.
Less flexibility!
The result was surprising, especially since monkeys are mammals known for their flexibility and ability to regulate their internal body temperature in line with changes in surrounding temperatures. However, researchers were astonished to find that the monkeys' overall immune system performance declined when exposed to around 86 degrees Fahrenheit, or 30 degrees Celsius, for nearly two weeks. This, in turn, affects the immune system's activity in the event of an actual threat. Researchers also observed a greater impact on younger monkeys in comparison to other age groups.
There are still many questions regarding the relationship between rising temperatures and the long-term effects on the immune systems of various wild animal species, and how this impacts the health of mammals. Researchers also need to delve into whether high temperatures affect the immune performance and health of humans to the same extent.
The study also highlights the necessity of studying the physiology of wild animals in light of the scenarios of rising temperatures and the changes the planet is undergoing today; this is important for preserving biodiversity and avoiding disruption of the ecosystem, as every living organism has a role in the integration and balance of that delicate system.
