Relationships between preferred body temperature in individual minnows and metabolic and behavioural traits. (a) standard metabolic rate (SMR); (b) aerobic scope (AS); and (c) activity, in common minnows fed either ad libitum throughout the entire 95-day study (control treatment; open circles), or food deprived for 21 days before being fed ad libitum for the remainder of the study (food-deprived treatment; dark circles). Each point represents one individual. Solid regression lines represent the significant main effects of SMR (panel a) and activity (panel c) on final preferred temperature described in Table1. There was no effect of aerobic scope (panel b) on preferred temperature.
