Quite often in environmental-economic literature (e.g. The Economics of Ecosystems and Biodiversity) welfare theory is used to calculate the supply of "ecosystem services" in "natural capital accounting" (NCA)?
I am interested in literature which views ecosystems in different ways, especially from a "network" perspective. For example, a food web or food chain seem to me to have network structures. Do you have any suggestions about the most important references in this field?
