It seems to me (not having read ANY of this albatross stuff first hand),
that the Phylogenetic Species Concept (PSC) is a middle ranking issue here.
Robertson & Nunn seem to be concerned principally about biodiversity
protection, and see the PSC as an enabling tool for that purpose. In
Australia subspecies receive protection under most federal & state
conservation legislation (perhaps all?), and so the PSC is not seen as being
a political necessity. In many other parts of the world only so-called
'full species' are covered - ssp are ignored - making the PSC a perhaps
understandably attractive proposition. The following reference gives a good
example of this approach, and there's also a reference for a rebuttal. I
can see various positives about the PSC, but political expediency as sole
justification is a poor excuse for deploying it IMHO.
