Interference among competitors
and deviations from the habitat matching rule With competition for resources
or reinforcement, individual gain is not only the result of individual
choices, but also the result of choice of other individuals in
the population. The gain function may be complex and include
an interference parameter (Sutherland, 1983). Such a parameter
may affect the distribution of individuals in a patchily environment.
When interference is the same in all the patches, the distribution
of individual may be easily predicted. When interference is different
in all the patches, the predictions are less easily obtained.
However, a graphical technique can be used. We show that we obtain
two kinds of correlated deviations from the habitat matching
rule (which states that the ratio of individuals should be equal
to the ratio of resources) when the interference parameter is
systematically varied. |
