The most interesting related  case I know of is the use of Franklin's magic 
number Ne=500 as a critical threshold for the ability of populations to evolve. 
The evolutionary model (not ecological) was used to motivate some of the early 
Northern Spotted Owl work. And it has been used elsewhere and favorably 
discussed in the journal Conservation Biology.

I take the magic number apart in a couple of papers on evolution in small 
populations (Foley, Patrick 1992. Small population genetic variation at loci 
under stabilizing selection. Evolution 46:763-774. Foley, Patrick 1994. 
Predicting extinction times from environmental stochasticity and carrying 
capacity. Conservation Biology 8:124-137), and most people seem to think this 
number was more metaphorical than real. It arose, in fact, due to a conceptual 
error in a paper by Franklin, nonetheless embraced by Michael Soule and others. 
Populations of any size can evolve. The problem is the interplay between 
natural selection and the arrival of new genetic variability.

Subject: [ECOLOG-L] Examples of Misuse of Ecological Models?

Hello Ecologgers,

I am looking for examples of where an ecological model was used to inform
an environmental management or policy decision, but the model was later
found to be inappropriate for the context in which it was used.

If anyone has an example or thoughts on this matter I would greatly
appreciate their input.

Please feel free to email me directly.

Thank you for your thoughts,
JB
