Proportions and temporal characteristics of the social components in the wild boar population.

The models fitted to the lagged association rates (LARs; see Figure 2) consist of a proportion of constant companions, rapid disassociations, and casual acquaintances of two types: permanent acquaintances lasting for particular period of time and casual acquaintances that last for shorter periods. This values correspond to percentage of each social component in the population. The standard error (SE range around the mean) of each parameter was estimated by jackknifing procedure. For a more detailed description and formulation of the models see Whitehead 1999 [31] and 2008 [57].
