Active crocodiles are less sociable

How animals move and associate with conspecifics is rarely random, with a population’s spatial structure forming the foundation on which the social behaviours of individuals form. Studies examining the spatial–social interface typically measure averaged behavioural differences between individuals; however, this neglects the inherent variation present within individuals and how it may impact the spatial-social interface. Here, we investigated differences in among-individual (co) variance in sociability, activity, and site fidelity in a population of wild estuarine crocodiles, Crocodylus porosus, across a 10-year period. By monitoring 118 crocodiles using coded acoustic transmitters and an array of fixed underwater receivers, we discovered that not only did individual crocodiles repeatably differed (among-individual variation) in each behaviour measured, but also in how consistently they expressed these behaviours through time (within-individual variation). As expected, crocodile activity..., , , # Data from: Active crocodiles are less sociable

In this study we quantified the degree of among (behavioural phenotypes) and within-individual (behavioural consistency) variation in sociability, daily activity, and site fidelity for a wild population of estuarine crocodiles *Crocodylus porosus*. We investigated whether an individual’s behavioural phenotype correlates with their consistency across consecutive tracking months and whether behaviours were correlated at the among-individual level, thus forming behavioural syndromes. We predicted that crocodiles would display both among- and within-individual variation in spatial and social phenotypes. Specifically, we hyp...
