The Wood Wide Web is a Metaphor

If it's just a biological marketplace, why does the system still favor old growth survival in managed forests where we try to optimize for yield? The broker theory doesn't explain why some species seem to prop up others even when there's no clear carbon profit for the fungus.
what happens to the broker when the host tree dies?
It reminds me of the telomerase craze mentioned in the June 30th threads. We mistake a biological mechanism for a functional outcome because the initial signal is exciting.
If we assume the fungus is purely a broker, would that not still result in an emergent property of community support? The lack of conscious altruism doesn't necessarily mean the system isn't functioning as a mutual support network in practice.
This is just the Dark Oxygen effect happening in botany. We are finally auditing the narrative because the tools for measuring carbon flux have actually improved. We have been trusting qualitative stories for decades while the quantitative data was basically a rounding error.
The shift toward isotope tracing has been really helpful here. It shows that while carbon moves, the net transfer is often too small to be the primary survival mechanism for the receiving tree.
I wonder if this applies to different biomes... does the broker model hold up in boreal forests as well as it does in tropical ones? The species diversity must change the exchange rate!
