Reproductive stratgegy Theory of Pests

There is the theory that species adopt one of the 3 life strategies in order to survive in a stable and unstable environment.


either of the 3 strategies are below:

1. r-section
2. k-selection
3. bet-hedging

But, What is a Stable environment?

Well it is not the UK! Stable environments are those climates that are relatively constant or easily predictable in there weather and other areas as well for example the tropical rainforest has a constant temperature of around 5/6 degree and a known mist of fog. Therefore, this is a stable environment.

So, What is a Unstable environment?

This is more like the UK, it is an unpredictable environment which varies in it climates. as well as this there is disturbances in the temperature zones.

Therefore Pests need to adapt to the environments by inhabiting to one of the 3 strategies above.
