What is Cyclical Succession? 🔄

  • Definition: Cyclical succession is the regular and repeating replacement of species in an ecosystem over time without needing big disturbances to trigger it.
  • Imagine a merry-go-round. Just like how the horses and seats take turns, species in cyclical succession take turns to dominate!

Examples from Around the World 🌍

🌳 North-west Europe

  • Scenario: Oak forests dominate but can't regenerate themselves. Why? Oak trees hate the shade.

  • What happens next?

    🤓 Real-world example: Think of oak forests like ice cream melting in the sun. If you put it back in the freezer (the grassland), it'll become ice cream again!

  • Other tree species or grasslands take over.
  • But here's the twist: Oak seedlings love grassland! They grow tall, shade out the grass, and BOOM! The oak forest returns.

California's Coastal Chaparral 🔥

  • Scenario: Deciduous shrubs and evergreen trees are the main players. But guess what? Fires! They happen every 10-15 years and sometimes even less frequently.

  • Fire's role: Resets the community, making it a hot (pun intended) spot for cyclical succession.

    🤓 Real-world example: Imagine the chaparral like a phoenix. After a fire, it rises again from its ashes.
