MODELING ENVIRONMENTAL STRESS 15 



Viewed in the context of such a unifying theory, labors with 

 disturbed ecosystems take on an added importance. Beyond yielding 

 answers to temporal questions of how best to manage impacted 

 ecosystems, they provide pieces for the unending puzzle of where we 

 come from and where we are headed.
