New Way to Measure Tortoise Body Temperature Without Stress

Topic: Environment

Scientists from San Diego Zoo Wildlife Alliance found a less invasive way to measure the body temperature of hatchling Mojave desert tortoises. They used a handheld infrared thermal camera, which can estimate internal body temperature without handling the animals.

A new study by researchers at the San Diego Zoo Wildlife Alliance has discovered a more gentle method for measuring the body temperature of young Mojave desert tortoises. This technique uses a handheld device called an infrared thermal camera.

In traditional methods, scientists would physically handle the tortoises and take their cloacal temperatures. However, this can cause stress to the animals. The new study found that the infrared camera can accurately estimate internal body temperature in hatchling Mojave desert tortoises under various conditions.

Body temperature is crucial for understanding how reptiles regulate their activity, use habitats, and respond to environmental changes. By reducing handling, thermal imaging may allow researchers to collect important data while minimizing stress and altered behavior. This is especially important when studying threatened species.

The study's findings can help guide future research in other turtle species and wildlife that are sensitive to temperature changes, particularly as scientists work to understand how species adapt to a warming climate.

Why It Matters

This discovery matters because it will help scientists study endangered tortoises without causing them stress. It also opens up new opportunities for research on how animals respond to climate change.
