2.3.4. Data analysis<br />

Analysis included the estimation of the proportion of area occupied (PAO) by jaguars,<br />
pumas, and ocelots over the entire study area, using the software PRESENCE 1 ; and<br />
estimation of species richness (SR) calculated for the western and eastern ranges of the<br />
study site, first separately and then combined for the entire area, using the software<br />
CAPTURE 2 (Otis et al. 1978, Rexstad & Burnham 1991). The small sample size prevented<br />
partitioning of data for further spatial comparisons.<br />
Both software packages attempt to estimate parameters (PAO and SR) using capture<br />
probabilities extracted from the data themselves, just like in capture-recapture models. The<br />
main concept behind these applications is that non-detection of a species at a site does<br />
not imply that the species is absent unless the probability of detection is 1.
