Yes. It's one of scope. Perhaps you can tackle it this way:
P.H. Greenwood (citation below) says that coexistence is the outcome of
coevolution. If you consider the fungi in your tree to be coevolv/ed/ing in
the way that they interact in exploiting the various
temporal/spatial/physiological niches at your site, then they are at least
beginning to coexist (so you may have a spectrum of coexistence, not a simple
