A)Identical plankton communities will develop in all ponds.
B)Similar plankton communities will develop in all ponds.
C)Different plankton communities will develop in all ponds.
D)Limited plankton communities will develop in all ponds.
E)Initially the number of species in each pond will be greater than the number normally found in similar environments.

If Gleason's hypothesis is correct, each species would colonize the ponds independently, leading to different plankton communities developing in each pond. This would suggest that environmental factors and chance events play a greater role than predictable interrelationships between species.
