Fig. 2: Quantitative assessment of the degree of faunal degradation using the Bray‒Curtis dissimilarity index.
From: Hunting indicators for community-led wildlife management in tropical Africa
The faunal composition of each camera trap (CT) within a hunting territory (N = 301 CTs) was individually compared with that of each camera trap (N = 38 CTs) at the reference site, Ivindo National Park (NP), using the Bray‒Curtis (BC) dissimilarity index. The distribution of the 11,438 dissimilarity values (301 × 38) is presented with a smoothed histogram per hunter community. A donut chart showing the proportions of CT detections of each major species group (rodents, ungulates, carnivores, apes, terrestrial birds and other species) is displayed for the Ivindo NP, Doumé (BC dissimilarity median = 0.66) and Bembicani (BC dissimilarity median = 0.85) study sites.
