Resolution or grouping aggregations used in comparisons
Figure 11
Resolution comparisons (open boxplots) and grouping comparisons (grey boxplots) of predator response variables. The
significance level of the Welch two-sample t-test is indicated by stars (*p
<
0.05). x-axis labels denote the level of aggregation used (as in
Table 1
and
Figures 1-3
). Specific system slopes are represented by colours with filled circles denoting a significance level of 95%. Black
diamonds connected by a dashed line show mean slopes for each response variable compared. For out-degree (vulnerability), no
comparison could be done between different levels of resolution. Abbreviations for the study systems are Broadstone Stream (Br),
Celtic Sea (Ce), Coilaco River (Co), Guampoe River (Gu), Trancura River (Tr), Tadnoll Brook (Ta), Afon Hirnant (Af).
