Figure 1. Diagrammatic representation of the experimental design used to
study exploitative competition between larval Colorado squawfish and fathead
minnow. Solid diagonal lines denote standard replacement series at three
densities. Dashed diagonal lines denote equivalent relative-abundance
experimental treatments, qo Colorado squawfish:9o fathead minnow. Arrows
illustrate method for comparing relative growth in mixed- and single-species
assemblages.
Figure 2. Observed data and fitted regression lines for Colorado squawfish
and fathead minnow relative growth in single-species assemblages.
Figure 3. Hypothetical relation of diet overlap for species sharing a
resource, as a function of resource availability. Relative position of three
data points correspond to observed experimental responses. Location of
response for lowest feeding regime is uncertain and alternate positions are
indicated. Modified from Wiens (1992), with permission.
