(a) Temporal shifts in focus of Esox lucius studies for five sub‐disciplines: ecology and evolution (
), behaviour (
), community ecology (
), physiology and disease (
) and toxicology (
). (b) The relative frequency distribution of papers that report on studies of E. lucius across four categories of scientific journals: miscellaneous (
), organism or environment specific (
), ecology and evolution oriented (
) and top ranked and general (
), has changed over time (χ
2 = 84·9, d.f. = 15, P < 0·001). (c) Average number of citations year−1 for papers published in different categories of scientific journals [same as in panel (b)] in different decades (ANCOVA, effect of decade: F
1,1679 = 6·24, P < 0·05; effect of journal category: F
3,1679 = 10·43, P < 0·001).
