Patterns and determinants of jaguar Panthera onca occurence in habitat corridors at the southwestern extent of the species range. Volume 11 Issue 1 Janpp. This article offers supplementary material which is provided at the end of the article. Volume 75 Issue 2 Janpp.

High jaguar densities and large population sizes in the core habitat of the southwestern Amazon. Consequently, the reduced forest area, with smaller and more isolated forest patches during annual flooding, could drive the comparatively larger home ranges observed in the Paraguayan Pantanal and Humid Chaco, although reduced jaguar densities resulting from persecution may also play a role in liberating ecorrfgiones space and permitting greater ecorrregiones use.

Volume 14 Issue 1 Janpp. My Content 1 Recently viewed 1 Space use and movement Consequently, GPS-based telemetry was used to study space use and movements of jaguars in western Paraguay in the Dry Chaco, Humid Chaco and Pantanal, the region with the largest jaguar population in the country.

Normality in the data was tested using the Shapiro-Wilk test and log-transforming the data when their distribution did not meet assumptions of normality. Cornell University Press, New York. Volume 54 Issue 1 Janpp. Home range, core area and movement parameter estimates Best fitting models for the movement of jaguars were either the OU or OUF models with 16 individuals demonstrating residency Table 1.

Consistent with expectations home range sizes of jaguars in the Dry Chaco were larger than in the Humid Chaco and Pantanal, overall and between sexes within systems where male home ranges were greater than females. The Dry Chaco is comprised of xeric forest, savannas and grasslands and the Humid Chaco and Pantanal are a mosaic of seasonally flooded grasslands, palm savanna and xerophilic woodlands on higher ground Olson 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.

Consequently, the OU and OUF models produce estimates of home range size and home range crossing time, while the OUF model additionally estimates the velocity autocorrelation time scale a measure of path sinuosity and mean distance traveled per day Fleming et al. Additionally, only individuals that exhibited residency in their movement behavior and space use [demonstrated by their variograms reaching an asymptote at approximately their home range crossing time Fleming et al.

These are the first estimates of movement parameters and home range and ecorregionds 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 account for autocorrelation in telemetry data when estimating space use Fleming et al.

Core areas of AKDE home ranges were estimated as the area encompassed within the isopleth where the proportional use of the estimated home range is equal to the predicted probability of use Seaman and PowellBingham and NoonVander Wal and Rodgers Jaguars were captured ecorregoones trained hounds to tree or bay jaguars which were then anesthetized using a weight-dependent dose of a mix of ketamine hydrochloride and xylazine hydrochloride injected by a dart shot from a tranquilizer gun McBride and McBride Plan de Manejo de la Panthera onca, Paraguay — Volume 47 Issue 1 Janpp.

Volume 67 Issue 1 Janpp. Based upon carnivore ecology in general, and jaguar ecology specifically, it was expected that male home range size and movement rates would be greater than those of females Sandel scorregiones, Cavalcanti and GeseConde et al.
