Survival and causes of mortality of introduced wild pigs in the presence of cougars

Wild pigs (Sus scrofa) are an introduced species that affect ecosystems through myriad pathways. They are the target of population control efforts, but one outstanding question is the extent to which native predators affect population demography. Cougars (Puma concolor) are a known predator of wild pigs and cooccur with wild pigs in several regions of the Americas. However, investigations of wild pig survival in regions with cougars are lacking. We investigated the survival and causes of mortality for wild pigs in California, USA where cougars could act as a predator. We also explored habitat selection of wild pigs with respect to cougar predation risk. We collared 69 wild pigs, 15 adults, 15 subadults, and 39 juveniles. Captures occurred in winter and spring and survival estimates primarily reflect spring and summer survival. We estimated 6-month survival of adults and juveniles to be 0.923 (95% confidence interval: 0.789 – 1.00) and 0.563 (0.416 – 0.762), respectively, which are simil..., These data include capture records and telemtry tracking data for wild pigs that were monitored with GPS collars and VHF ear tags. Raw location data are provided for the GPS collars. VHF ear tag data provides the date and status of observed pigs throughout the monitoring period. Location data for cougars are not provided due to the sensitive nature of these data., , # Data from: Survival and causes of mortality of introduced wild pigs in the presence of cougars

Metadata for the manuscript 'Pig Survival and causes of mortality of introduced wild pigs in the presence of cougars' published in Biological Invasions by MA Parsons, KC Vercauteren, JA Dellinger, and JK Young.

The data and R code provided here can be used to recreate results from this manuscript. The data files included several raster layers of topographic and landcover variables, capture and survival monitoring data for collared wild pigs, and a probability of cougar kill occurrence raster.

The R scripts conduct all analyses including survival analysis of wild pigs, a resource selection function of cougar kill sites, and a step selection function for wild pigs.
