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) https://datingranking.net/local-hookup/brisbane/, 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).

Spatiotemporal sampling work and you can precision
Improving the level of sampling metropolitan areas got a somewhat large perception as compared to duration of sampling per venue (into the weeks) on the precision off prices off duiker find prices, however, a dramatically large influence on the precision away from chimpanzee come upon prices (Dining table 4). Estimated coefficients to have leopards (perhaps not demonstrated) indicated merely a tiny effectation of level of urban centers. 繼續閱讀 Occurrence quotes imply that duikers (/kilometer 2 ) was everything 40 times way more plentiful than chimpanzees (?0
