7. Behavioral Cycles: Hibernation, Dormancy and Migration


Cycles in Plants
Plants become dormant in periods of unfavorable conditions, such as losing leaves in winter. Triggers include responses to light, day length.
Plants also respond to gravity.

Animal Behaviors: Instinct or Learned
What is the difference?
Read about bee communication...how does this information show the difference between instinctual behaviors and learned behaviors?

  • Exploration:
    Migration
    Food and reproductive opportunities are powerful factors in the lives of animals, and animals consequently they expend a great deal of energy in pursuit of both.



    Most behavioral patterns relate in some way to daily, monthly, or seasonal environmental cycles. These videos depict animal migrations in relation to seasonal cycles, including cycles of growth and reproduction in other organisms. As you watch the videos, think about these questions and record your responses: 1. What environmental factors influence the behaviors of the animals in the videos at different stages of their migrations? 2. Why do you think the animals rely on those particular factors and not others? 3. How do these animals know the way the first time they travel their migration route? 4. How does the timing of migration affect an animal's ability to survive and/or reproduce?

    • Write a paragraph or two describing the use of a combination of innate (inborn) and learned behaviors during the migration of one of the species depicted in the videos. Why do you think relying on one type of behavior -- either innate or learned -- rather than on a combination, might be a disadvantage for an animal?

Watch these examples:
How do they know the way?
Why do they migrate?
Where do they leave from, where do they go?
Migration: what is it?
