Hi, in my opinion this article has potential to grow to a

• Sharon L. Hanks, Sharon La Bonde, Ecology and the Biosphere: Principles and Problems pag 52, see here.

The introduce here "a simplified ecosystem model using odum's energy language". It seems to me this is a grafical and not a mathematical representations of an ecosystem. based on this, the first sentence can be changed into:

• Ecosystem models, or ecological models, are conceptual, graphical and or mathematical representations of ecosystems.

And in the line of this change of scoop, this article can clear some more about conceptual and graphical Ecosystem representations? -- Mdd (talk) 14:30, 11 April 2008 (UTC)[reply]

I'd agree with this addition, though we should be clear that modern ecosystem models are typically different in form (if not intention) than historical models. Historically, building up a diagrammatic food web that linked components could be described as an ecosystem model, but these days most people mean a quantitative description of the components of an ecosystem and the relationships between them. Going further, ecosystem models presently in the scientific literature are typically systems of

difference equations or ordinary differential equations that represent major ecosystem components (e.g. plants, animals, dead material), and that have mathematical functional response

relationships linking them (e.g. primary production, grazing, mortality).

Anyway, thanks for your interest. Cheers, --Plumbago (talk) 15:53, 11 April 2008 (UTC)[reply]

I am running the WikiProject Systems and from that perspective I want to contribute to the improvement of all systems theory related content in Wikipedia. If you interested I like to work with you in the further improvement of this article. More on the general, coneptual and grafical part. I think there are multiple things we can do:

• Improve the content of this article, as we started talking about
• Add some picture: I did digging and restrucuring in Wikicommons in the Commons:Category:Ecosystems and in commons:Category:Ecological diagrams
• Add some more examples
• Add some more links from and towards this article
• And a short version of this article can be added to the ecosystem article

I think we can create a larger audience for this article. Last month this article was viewed 1300 times and the ecosystem article 67726 times. Some more of the people who looked at that article should come and take a look here. These are just some of my ideas. -- Mdd (talk) 01:02, 12 April 2008 (UTC)[reply]

Unsourced and not particularly relevant to the subject. — Arthur Rubin (talk) 02:35, 29 January 2012 (UTC)[reply]

• I have reinstated information on Ecopath, which certainly has a place in this article as the most prominent and widely used ecosystem modelling system. --Epipelagic (talk) 03:27, 29 January 2012 (UTC)[reply]

That's a much better location; even if the most prominent, it shouldn't be in the lead. — Arthur Rubin (talk) 10:15, 29 January 2012 (UTC)[reply]

Hello fellow Wikipedians,

I have just modified one external link on Ecosystem model. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
