Data collection
Camera-trapping
We analyzed 125 independent jaguar events of presence obtained from
9,360 camera trap-days recorded over a 180-day; independence was
established for records at one-hour intervals. Following the guidelines
of National Jaguar Census and Their Prey (CENJAGUAR) (Chávez et
al ., 2007; Chávez et al ., 2016), 42 camera traps were placed
throughout the 108 km2 study area partitioned into
nine smaller 9 km² grids. Each grid was equipped with three camera trap
stations that included one double and two single camera traps with a
separation of 1 to 1.5 km between stations.
GPS Tracking
Jaguars were captured used trained hounds to locate and aid in the
capture of five adult jaguars between 2018 and 2019, followed the
procedures employed in previous research (Crawshaw and Quigley, 1991;
Hoogesteijn et al ., 1992; Morato et al ., 2001). We
deployed global positioning system (GPS) radio collars (Telonics TGW47)
on adult jaguars, which were programmed to record one location point
every two hours and to transmit weekly; we collected a total of 16,441
location data points (from all jaguars). We obtained permission for
capturing and handling jaguars from Dirección General de Vida Silvestre,
Secretaria del Medio Ambiente y Recursos Naturales (SEMARNAT).
