On the spatial clustering of behavioural phenotypes: matching movement tactics with landscape structure in a large herbivore

Oikos, EarlyView.
In the wild, individuals consistently differ in movement and space use behaviours, depending on their personality. This variation can lead to personality–habitat associations and spatial structuring, potentially generating individual niche segregation.
