when migratory pathways intercept Anoplolepis supercolonies.
This effect at a distance can deplete crab populations in
areas not directly invaded by the crazy ant, setting in train
indirect effects on seedling abundance and litter decomposition.
However, this was unlikely to have affected control
plots during our study; burrow densities on these plots were
within the range reported prior to the widespread formation
of crazy ant supercolonies (Green 1997).
