Figure 2.
A depiction of the potential ecosystem-effects of copepods.
Copepods might influence ecosystem functions as well as the biological, chemical, and physical properties of ecosystems. The bars are proportional to the average standardized effect sizes (Cohen's ) for species contrasts (black bars) and population contrasts (grey bars), as summarized in Table 2. Stars indicate if the ecosystem metric had at least one significant contrast (at the level of
0.05), as indicated in Table 2.
Figure 3.
A schematic of the contrasts used in the copepod experiment.
See the text for an explanation of the contrasts. The treatment labels indicate the species (uppercase), source population (subscript before the period), and rearing environment (subscript after the period). The three species are: (SO),
(HF), and
(LA). The origins of the source populations are: Killarney Lake (K), Loon Lake (L), Mitchell Lake (M), Harrison Lake (H), and Osoyoos Lake (O). The rearing environments are: Lab-reared (Lab), and Wild-caught (W).

Figure 4.
A summary of the ecosystem properties and functions that were influence by copepods.
The vertical dashed line separates copepods that were either raised in the lab (left of line) or wild-caught in the field (right of line). The dotted lines connect treatments that are significantly different, based on Tukey's Post hoc contrasts ( = 0.05). See Table 2 to see which specific contrasts (defined in Figure 3) were significant.
