Abstract

We investigate the structural properties of an ecosystem model, and show that the model and the field data share similar characteristics. In particular, our model suggests that the universal scaling of the “spanning tree,” which has been discussed using the field data on fewer than 100 species only, can be valid on a larger scale.
