Table 4 Mean badger social group size for secondary (SSC) and main sett clusters (MSC and MSCR) at the 13 study sites in France, based on (i) adults using camera traps (adSSC, adMSC, adMSCR) and (ii) badgers (adults and cubs) using camera traps and genetic identification (badgerSSC, badgerMSC, badgerMSCR)

From: Breaking down population density into different components to better understand its spatial variation
