Zoologists have proposed cutting koala mortality among orphans by implementing a rapid stress assessment that can be run regularly. This approach was presented by researchers at the University of Queensland and builds on the need to safeguard young koalas whose survival hinges on effective welfare monitoring.
Rather than drawing blood, the new technique evaluates stress through stool samples. By analyzing these noninvasive specimens, researchers can gauge physiological responses without subjecting the animals to invasive procedures, which in turn can lessen additional stress during rehabilitation.
“Traditional test kits are produced in limited numbers and require a lot of labor, so doing these types of tests on a regular basis can be quite challenging. We tested our own test, an easy-to-use kit that avoids invasive blood testing,” the researchers explain. The kit enables field teams to collect and interpret data swiftly, supporting timely interventions for stressed individuals.
The stool analysis can identify specific biomarkers associated with stress, allowing veterinarians and wildlife carers to monitor welfare and adjust care plans accordingly. This proactive approach helps ensure that medical and environmental conditions are optimized for recovery and safe release back into the wild when possible.
Many koalas are orphaned at a young age due to habitat destruction, car collisions, dog attacks, wildfires and numerous other threats. When these animals are brought into shelters, they receive care and rehabilitation, yet mortality remains a pressing concern. Stress is recognized as a key factor affecting outcomes, so the ability to regularly track stress levels gives experts a practical tool for improving survival rates. Importantly, the noninvasive test reduces stress itself, creating a more humane and efficient workflow for caretakers.
Historical researchers have explored how diet and supplemental substances can influence the health and functioning of laboratory animals. While the primary focus for koalas is stress management and welfare, these broader findings highlight how nutrition plays a critical role in resilience and recovery across species.
