25 Giu Occurrence rates mean that duikers (/km dos ) had been approximately 40 moments a lot more abundant than simply chimpanzees (?0
5/km 2 ), and approximately 400 times more abundant than leopards and elephants (?0.05/km 2 ; Table 3). We estimated that 13 elephants, 10–14 leopards (depending on availability estimator), 87–109 chimpanzees (depending on availability estimator), and 3949 Maxwell's duikers occupied our 200-km 2 study area (Table 3). Estimates for duikers were the most precise (CV = 11%); estimates for chimpanzees were reasonably precise (20% < CV < 30%), and estimates for elephants were potentially too imprecise to be useful (50% < CV < 200%; Table 3). The analytic estimator yielded variances that were larger than those estimated by bootstrapping (except for very rare elephants), and only slightly larger than the variance of the encounter rate calculated from the raw data (Table 3).
- Plus found is actually %CVs of the come across speed ( var ^ p 2 ) calculated regarding the raw investigation, and projected society items (N) having bootstrap LCLs and you may UCLs.

Spatiotemporal testing energy and you can reliability
Raising the amount of testing metropolises had a somewhat large effect compared to the duration of testing per area (from inside the weeks) to your precision away from prices out of duiker find pricing, but a somewhat large impact on the accuracy off chimpanzee come across prices (Dining table cuatro).
