Folks might want to take a look at this paper (after doing the survey!). Fauth, J. E., J. Bernardo, M. Camara, W. J. Resetarits, Jr., S.A. McCollum, and J. Van Buskirk. 1996. A conceptual approach to simplifying the jargon of community ecology. American Naturalist 147:282-286.
It includes definitions based on the original usage of the terms and a logical conceptual framework. You can get the pdf from my sadly in need of updating website. http://www.myweb.ttu.edu/wresetar/ It would be interesting to see how differently these terms are actually used, since my impression is that usage of most of these terms does not show any consistency with actual definitions. In common usage, it seems a "community" is still "that group of organisms on which I worked." "Community" is thus used in place of every set included in the survey (and many that are not). So, while most may be able to define the terms, they may still not use them consistent with the definitions. Part of the problem is that predator communities and prey communities are particularly common usages that fit no known definition of community. So, while we have good definitions for many "sets" in community ecology, the particular constructs of "predator" and "prey" are more than a little problematic when dealing with groups that are not taxonomically proscribed. Some sets of predators might be roughly categorized as a guild, but diverse sets of predators that don't utilize similar resources in a similar way present a definitional problem. So, predators, in general usage, share a vaguely defined common food "type". How should one refer to all the predators in a given locality? I would argue that "predator communities" is a non sequitur, since I know of no communities that consist only of predators, and few that consist primarily of predators. But what is a proper description of a set of predators? For prey, it is even more vague, since the only thing prey share is the risk of being eaten. And so "prey communities" makes even less sense logically, since you can't even BE prey unless there are predators in your community! I have searched in vain for a simply term from the actuarial and insurance side of things for groups that share a common risk. What should we call groups of unrelated "prey" in a community. Simply saying prey, like predator, does not specify a set, but can refer to single or multiple prey species. William J.
