Given the status of the jaguar in Paraguay, the lack of information on the spatial and movement ecology of the species is of concern within the context of continued habitat loss, the maintenance of in-country and trans-boundary connectivity of populations, and their ecorreigones for the range-wide conservation of the jaguar.

Volume 75 Issue 2 Janpp. Carnivore ecology and conservation: Volume 32 Issue 4 Janpp. Volume 14 Issue 1 Janpp. For a big cat the jaguar is relatively understudied Brodieand although multiple studies have estimated jaguar home range size Schaller and CrawshawRabinowitz and NottinghamCrawshaw and QuigleyCrawshawScognamillo et al. Data collected with an irregular sampling schedule starting in were accounted for using the dt argument within the variogram function in the ctmm package Calabrese et al.

This indicates that despite home range size, sex, or system jaguars are most intensively using about a third of their home range area. When applied to serially autocorrelated data AKDE more accurately estimates home range compared to traditional kernel density estimation KDE; Worton as KDE assumes independent identically distributed data IIDwhich when violated, can result in greatly underestimated home range size Fleming et al.

Volume 37 Issue 2 Janpp. Occupancy estimation of jaguar Panthera onca to assess the value of east-central Mexico as a jaguar corridor. Results Jaguar captures and data collection From June to June 35 jaguars were captured and collared, of which 19 individuals provided sufficient data for analysis; seven in the Dry Chaco five males, two femalesnine in the Humid Chaco three males, six females and three in the Pantanal one male, two females with estimated ages between 2 and 10 years Table 1.

Volume 39 Issue 3 Janpp. Apart from constituting an important contribution towards the conservation of jaguars within Paraguay, placing the results into a comparative context with research from neighboring countries will facilitate the efficacy of trans-boundary conservation efforts, with important implications for range-wide conservation strategies for jaguar.

Planning to save a species: Volume 34 Issue 1 Janpp. Volume 47 Issue 1 Janpp. Jaguar captures Jaguars were captured using trained hounds to tree or bay jaguars which were then anesthetized using ecorregionds weight-dependent dose of a mix of ketamine hydrochloride and xylazine hydrochloride injected by a dart shot from a tranquilizer gun McBride and McBride Movement patterns of jaguar.

Overall and between systems male home ranges were larger than females which was expected Cavalcanti and GeseSollmann et al. Volume 78 Issue 4 Novpp. These are the first estimates of movement parameters and home range and core area for jaguar in the Dry Chaco, Humid Chaco, and Paraguayan Pantanal, which furthermore take advantage of developing methods to empirically test for home range residency and ecorregionss for autocorrelation in telemetry data when estimating space drl Fleming et al.

Volume 46 Issue 4 Janpp. Volume 27 Issue 1 Janpp. The larger home ranges in the Dry Chaco are attributable to the lower productivity of that semi-arid ecosystem, more heterogeneously distributed prey and water, and negative effects of anthropogenic factors apraguay. Kernel methods for estimating the utilization distribution in home-range studies. Volume 35 Issue 1 Janpp. Volume 54 Issue 1 Janpp. Consequently, the reduced forest area, with smaller and more isolated forest patches during annual flooding, could drive the comparatively larger home ranges paragiay in ecortegiones Paraguayan Pantanal and Humid Chaco, although reduced jaguar densities resulting from persecution may also play a role in liberating available space and permitting greater space use.

Estimation of the density of the near threatened jaguar Panthera onca in Sonora, Mexico, using camera trapping and an open population model. The analysis was undertaken in R 3.
