 radiation to increase the genetic load (and even that would probably not be 
 enough), it would take one farfetched or astronomical piece of "luck" to
 a population with chaotic enough alleles to do any "damage" or change the 
 region's or nation's monarch population in any noticeable way.  They are 
 migratory and have a high degree of dispersal built into their ethology.  
 There's no artificial selection going on here, the population is not being 
 infused and confined through numerous generations.   >>

At last we have someone who really has stated a valid point regarding release
of locally-bred monarchs.  The above is "must"-reading for anyone getting
into the Monarch-release debate.  Thanks for the education Bob.
