Individual phenotypic variability in the behaviour of an aggregative riverine fish is structured along a reactive-proactive axis.

Abstract excerpt

High phenotypic diversity should provide populations with resilience to environmental change by increasing their capacity to respond to changing conditions. The aim of this study was to identify whether there is consistency in individual behaviours on a reactive-proactive axis in European barbel Barbus barbus ("barbel"), a riverine and aggregatory fish that expresses individual differences in its behaviours in...
