Two species

Index

  1. Physical environments

  • Spatial heterogeneity

  • Phenology

  1. Movement

  2. Species interactions

  • Resource competition

  • Interference competition

  • Reproductive interference

2. Movement

Movement (i.e., immigration & emigration) change population at each point. The simplest model is diffusive Lotka-Volterra model.


Here is the code.

3. Species interactions

  1. Exploitive competition

Exploitive competition means ...

Examples are ...

  • Resource competition


  1. Interference competition

Interference competition means ecological interactions with which two species compete for shared or limiging resources and reduce each other fitness directly. In theory, the Lotka-Volterra model proposes the condition of interference competition when interspecific competition is greater than intraspecific one. Biological factors of interference competition are ...

  • Agression (e.g., territory)

    • Contest competition

  • Chemical competition (e.g., Allelopathy, Poisons given off from bacteria...)
