Food webs found in nature tolerate variable environments despite theoretical model predictions of diversity leading to instability and high extinction risks. Contradictions may be explained by lack of stabilizing mechanisms in models.

The aim of this study was to explore how:

1. environmental variation
   
2. environmental response
3. dispersal

affect food web stability, extinction risk, synchrony between species and colour of population time series.
I searched for explanations to contradictions in food web research. 

Colored environmental variation and dispersal between subpopulations were incorporated into a diamond shaped food web based on a model by Vasseur and Fox 2007.
