Orangutan's diet adapts to feast or famine
UC professor's work shines light on metabolic disorders like diabetes
Science writers highlighted a study by an international team of researchers led by Rutgers University that examined how orangutans adapt to changeable periods of feast or famine.
University of Cincinnati geosciences Professor Brooke Crowley contributed to the project that examined how orangutans maintain their weight by adjusting their diet during periods of bounty or scarcity.
The study was published in the journal Science Advances.
Orangutans reduce their physical activity during periods of fruit scarcity to conserve energy.
They rest more, go to sleep earlier, travel less and spend less time with other orangutans. This flexibility enables them to use body fat and protein for fuel when needed. They rebuild fat reserves and muscle when fruit becomes more available.
The study demonstrated the great apes' metabolic flexibility, which allows them to maintain their health in times of food stress.
“Understanding these adaptations can help us learn more about how humans can manage their diets and health,” said lead author Erin Vogel, a professor of anthropology at Rutgers University-New Brunswick. “It also highlights the importance of conserving orangutan habitats to ensure their survival.”
UC's Crowley uses tools such as strontium analysis to study the diets, habitat needs and movements of reclusive, endangered or long-extinct animals.

Amy Townsend-Small, a College of Arts and Sciences professor, won the 2026 Sustainability Leadership award for her nearly two decades of work looking into the oil and gas industries. Townsend-Small, who teaches for the School of Environment and Sustainability (SEaS), said she studies where methane is emitted through the life cycle of natural gas, and what can be done to reduce emissions. Methane, according to Townsend-Small, is very good at trapping heat in the atmosphere. Specifically, she works to quantify the emissions with the goal to be providing accurate data for policy change.
