In the eye of several arthropods one can observe pigment migration in a diurnal or circadian way. Deposit a glass vial with fermentizing banana in an area where Drosophila is found. The number of flies caught depends in a characteristic way on the time of day for the different species. On page it was already referred to the diurnal rhythmicity of locomotion and of body temperature of man. The phase of these rhythms depends on the chronobiological phase type, i.e. whether somebody is more a morning or an evening type.
Chronobiological topics are also interesting for adult education courses and are used there.
Scientist working in this field are usually willing to report about their work. Proposals for own observations and projects can be offered such as the one on page .
