Snails were collected from the forest and taken back to the laboratory where a piece of string was tied securely around the shell. They also devised a clever way to compare survival rates of snails in the trees and on the ground. The temperature and humidity of the tree canopy was measured and compared to that of the ground. They compared the snails' activities with those of the ground-dwelling carabine beetle, known to eat land snails. Saeki and her colleagues observed the snails in the trees from tall observation towers, as well as on the ground, during different seasons of the year.

To find out why the snails leave the dark, humid earth for the light, dry canopy, Prof. During winter, the snails hibernate on the ground in the leaf litter, moving into the tree tops in the spring and then coming back down to earth in autumn.

These snails, Sapporo mai-mai ( Euhadra brandtii sapporo), live in a small area in the southern part of Hokkaido Island, Japan, in a cool, wet forest, full of trees such as oak and maple. Saeki and her colleagues decided to enlist the help of a Japanese tree-climbing land snail. Is it because there are fewer predators, or less competition with other animals? Is there more, or better, food? Some studies suggest that tree-dwelling species live longer than ground dwellers, but this idea, along with the others, is not easy to test in a natural environment. Saeki wanted to know what drives animals to leave the ground, defying gravity to live in the tree tops.
