Can we do something like bio-economic analysis?

Can we do something like bio-economic analysis?

　There may already be such a thing, but is it possible to do something like economic analysis using living organisms? For example, we could analyze the situation of a city by looking at its crows.

　Is it possible to do some kind of economic analysis using familiar animals, or rather, using familiar animals as indicators? It may be difficult to prove or determine causality, but can we at least get some kind of correlation or trend? I think it would be interesting to have something like that.

　At least, Twitter is used for economic trend analysis, so I wonder if there is such a thing. Or maybe there is.

　I think there is an economy that uses weather, like weather economics, so I think it would be good to have an economic analysis that uses living things.
