OVERCROWDING

OVERCROWDING

OVERCROWDING

Overcrowding is when there is insufficient space for each organism to function properly.

Factors that may lead to overcrowding

  1. Natality (Birth rate)
  2. Immigration
  3. Social habit
  4. Inadequate dispersal methods
  5. Predators are rare.

Overcrowding

  1. There is not enough space
  2. Food shortages are unavoidable.
  3. Competition between species or intra-species
  4. Predators-prey relationship.
  5. It is a game of catching up with each other.
  6. Cannibalism might ensue.
  7. Choky environments can lead to death (epidemics).
  8. Reduction in reproduction (decrease in natality).

Adaptations to Avoid Overcrowding.

  • Territorial behavior – (baboons, baboons, and some birds).
  • Dispersal of fruits, seeds, and animals
  • Swarming (bees, termites).
  • Irruptions are large-scale migrations of animals that occur at regular intervals, just like in locusts.

Locust comes in two forms.

  • The single phase
  • The migration phase.

The solidarity phase is where the locust behaves just like any other grasshopper. It’s not more destructive than any other grasshopper. The number of locusts increases dramatically in hot and humid weather. Overcrowding occurs when the number of locusts increases. Young overcrowded locusts experience hormonal changes.

This causes the development of longer wings, a slenderer body, and a darker color. The nymph, a migratory phase known as hoppers, is large in number. They fly out in large numbers (between 5000 and 10,000 million) when they are adults.
