Function and Applications

This ring-shaped apparatus enables a temperature gradient to be formed and is a valuable tool for working out ecological relationships.

Benefits

• It allows, e.g., to observe the influence of the temperature of soil on germination and growth of plants
• Soil organisms placed in the temperature organ can move freely and migrate the region they prefer so that their temperature and/or moisture preferences can be studied
