Animal Migration and Hibernation Concepts

The video discusses how animals respond to abiotic conditions through migration and suspension. Migration is a temporary movement to avoid unsuitable conditions, influenced by factors like photoperiod and food availability. Birds and fishes exhibit migration, with examples like Siberian cranes and catadromous fishes. Suspension responses include hibernation, estivation, and diapause, allowing animals to survive extreme conditions. Adaptations play a crucial role in helping animals and plants cope with these challenges.
