FIG.
E1. Relationship between i,
larval survivorship, and fecundity. Contours denote lines of equal ,
with the highest values of population growth rate occurring in the upper
right hand of the plot. Survivorship had a stronger affect on Callibaetis
i than
fecundity over the range of observed values (contours are more nearly horizontal
than vertical). All sinks (
< 1.0), except one, contained trout, and sources (
> 1.0) were either fishless or contained trout. Open circles = Fishless
Control; Closed circles = Trout Control; Dotted triangles = Introduction
Ponds; Solid triangles = Trout Reduction ponds. |
