Table 2 Definition of terms used throughout the systematic review
Term | Definitions |
|---|---|
Article | An independent publication (i.e., the primary source of relevant information). Can be from commercially published or grey literature sources. Used throughout the review |
Site | A specific hydroelectric facility (i.e., hydro dam) where observations or experiments were conducted and reported in one or more articles. Used throughout the review |
Study | An experiment or observation that was undertaken over a specific time period at particular sites reported as separate waterbodies that were not treated as replicates within a single article. Used throughout the review |
Project | Individual investigations within a study that differ with respect to ≥ 1 aspect of the study validity criteria (e.g., replication). Used in the review descriptive statistics and narrative review |
Case | Situationally defined in text/visual aids (e.g., separate counts of fish life stages) within an independent study. Used in review descriptive statistics and narrative review |
Dataset | (1) A single independent study from a single article; or (2) when a single independent study reported separate relevant comparisons for the same or different species and different: (a) operating conditions (e.g., different flow magnitudes/intensities, operational regime); (b) outcome categories (i.e., biomass or abundance); (c) life stages for the same outcome category (e.g., the abundance of eggs for species X and the abundance of age-0 for species X) but otherwise with the same meta-data; (d) outcome metrics within a particular outcome category (i.e., abundance and density or CPUE; or biomass and yield) but otherwise the same meta-data; (e) sampling methods but otherwise with the same meta-data; (f) years and/or seasons post-treatment within a given outcome category (i.e., if for a given outcome category, multiple after time periods were monitored and reported separately for a CI study design or within-in year variation post-treatment for a BA design), and/or (g) sites downstream of a hydro dam within a single river sampled using a BA design but otherwise the same meta-data.
