Competition for food, literature question

[Ernest Williams]

Clench's interpretation has been challenged because the skipper community
he described did not exist as a long-time interactive community.  See Shuey
1986(87), J. Res. Lepid. 25(3):202-206.  Since John is active on this list,
perhaps he might like to comment further.
