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).
- In addition to shown is actually %CVs of one’s encounter rates ( var ^ p dos ) computed in the intense analysis, and estimated people models (N) with bootstrap LCLs and you will UCLs.

Spatiotemporal testing effort and you will accuracy
Increasing the quantity of sampling towns had a slightly huge effect than the duration of testing for each area (during the days) to the reliability out of quotes off duiker encounter rates, however, a significantly larger affect the accuracy regarding chimpanzee encounter prices (Desk 4).Continue Reading..
