What is the primary use of infrared imaging in ecology?

In ecology, infrared imaging is primarily used to monitor moisture levels in the environment. This technique utilizes infrared wavelengths to detect heat emitted by objects, which allows researchers to analyze the thermal properties of various surfaces, including soil and vegetation.

Moisture levels significantly influence the temperature of materials; for instance, wet soil will have a different thermal signature compared to dry soil. By using infrared imaging, ecologists can identify variations in moisture content over large areas, leading to important insights into ecosystem health, plant stress, and water availability. This capability aids in understanding vegetation dynamics and habitat conditions that can affect wildlife habitats and vegetation patterns.

While other options such as measuring temperature changes or visualizing animal migration also involve infrared imaging, they are not its primary ecological application. Identifying mineral deposits does not fall under ecological assessment but rather relates to geology and resource exploration. Thus, monitoring moisture is the most relevant and widely recognized use of infrared imaging in the field of ecology.
