Climate-induced migration is a highly complex issue which needs to be understood as part of global migration dynamics. Migration typically has multiple causes, and environmental factors are intertwined with other social and economic factors, which themselves can be influenced by environmental changes.
Circadian migration is where birds utilise circadian rhythm (CR) to regulate migration in both fall and spring. In circadian migration, clocks of both circadian (daily) and circannual (annual) patterns are used to determine the birds' orientation in both time and space as they migrate from one destination to the next.
Insect migration is the seasonal movement of insects, particularly those by species of dragonflies, beetles, butterflies and moths. The distance can vary with species and in most cases, these movements involve large numbers of individuals.
