I am investigating the functionality of a lotic river and would like to calculate the exergy to compare with the values of other biotic and abiotic parameters to obtain a quality scale of ecosystem functionality. So I need the values of the βi coefficients in accordance with the Functional Feeding Groups (FFGs) of the macroinvertebrate community of a lotic river.
Dear Maurizio.
You can find out information in the following book:
Ecosistemas de aguas continentales.Metodologías para su estudio.(Estela C.Lopretto,Guillermo Tell directores).T.1.Ediciones Sur.1995.377p.
The address of Ediciones Sur is: 60 No.226.(1900) La Plata.república Argentina.
Best wishes.
Dear Maurizio,
you may also be interested in the βi coefficients for trophic levels in the following publications:

Jørgensen, S.E. et al.2002. Explanation of the observed structure of functional feeding groups of aquatic macro-invertebrates by an ecological model
and the maximum exergy principle Ecological Modelling 158: 223-231
Best wishes
thank you very much
the first-one I know already, I will look for the second-one
