Use of space and homesite attendance by Iberian wolves during the breeding season

However, little is known about the breeding behaviour of large carnivores in these landscapes, though this is important for conservation management. Here we describe the space use and homesite attendance patterns of wolves inhabiting humanised landscapes of north-western Portugal, based on GPS tracking of 11 individuals in 2008–2013. Parturitions (N = 3) occurred in late May, with pups remaining at natal dens for 24–85 days, after which they were moved to a first and then sometimes to a second rendezvous site. Two of these movements were associated with human disturbance events. Breeding females (N = 4) spent a large proportion of time with pups during pre-weaning (≈2 months after birth), leaving only at night during short periods; thereafter they progressively reduced time at homesites (i.e, natal dens and rendezvous sites), and increased both daily travel distances and daytime activity. Throughout the pup-rearing season, breeding females restricted their movements to within ≈2 km of homesites. Non-breeding females (N = 4) showed significantly lower attendance rates than breedi...
