Comparison between Ecopath with Ecosim and Mizer #54

Open gustavdelius opened 5 years ago

gustavdelius commented 5 years ago

I think it would be very useful to have a page on our website that helps people who already know Ecopath with Ecosim to understand mizer.

Luckily, Peter West (@peterwest17), a Master student at the University of the Algarve, is doing his masters project on a comparison between EwE and Mizer by creating a mizer model for an ecosystem for which there is already an Ecopath model, described in Gamito, Sofia, and Karim Erzini. “Trophic Food Web and Ecosystem Attributes of a Water Reservoir of the Ria Formosa (South Portugal).” Ecological Modelling 181, no. 4 (February 2005): 509–20. https://doi.org/10.1016/j.ecolmodel.2004.02.024. The project is supervised by Karim Erzini and myself.

Peter is currently working on relating the quantities and rates in the Ecopath model to integrals over the size-resolved quantities and rates in mizer.

The attached paper also does some comparison between size spectrum models and EcoSim.

Ken, the paper you linked does not appear to mention Ecosim. Did you perhaps mean the following paper? Jacobsen, Nis S, Timothy E. Essington, and Ken H. Andersen. “Comparing Model Predictions for Ecosystem Based Management.” Canadian Journal of Fisheries and Aquatic Sciences, August 5, 2015, 150805143639004. https://doi.org/10.1139/cjfas-2014-0561.

Peter had found this paper, but he wants to do the comparison not in a trait-based model but in a multi-species model.
