Pangolins have long been hunted for food and for their scales, but information on local hunting strategies in African range countries and the patterns of pangolin trafficking around sourcing areas is limited. Such knowledge is vital to inform monitoring approaches and conservation interventions. We administered questionnaires to 367 people from 20 villages around two national parks in Cameroon to gain insights into local hunting practices, and trading and trafficking patterns. We found that tracking was the preferred method of hunting pangolins. Trapping was also used, and setting traps on fallen logs and near burrows improved the likelihood of catching pangolins. The white-bellied pangolin Phataginus tricuspis was the most traded species, and the giant pangolin Smutsia gigantea was the most sought after. We found no evidence of trade in the black-bellied pangolin Phataginus tetradactyla. Most respondents stated that pangolin prices had increased over the last 5 years, and scarcity of pangolins was the primary reason given for this increase. We identified a pangolin scale trafficking network operating from rural communities to neighbouring cities. Although most respondents recognized that hunting pangolins is illegal, c. 30% indicated that they were engaged in pangolin hunting.

This study explores the relationship between body mass and femoral construction in armoured (dasypodids and manids) and unarmoured (caviomorph rodents) mammals. Predictive equations based on diaphyseal cross-sectional parameters provided the most accurate estimates of body mass in caviomorph rodents and dasypodids. When these equations are applied to the estimation of body mass in manids, relatively low predictive errors (<20%) are found only when caviomorph equations derived with diaphyseal cross-sectional area or moments of area are used. Dasypodid equations generally yield less accurate estimates for manids, so that armouring of the integument alone poorly discriminates femoral types. Other factors with potential to differentially impact femoral construction are also considered: although locomotor speed strongly influences mass–structure relationships within caviomorph rodents, the confounding influence of locomotor posture, fossoriality, and arboreality render these relationships less predictable across all three groups considered here. Limb structure and, hence, scaling patterns of each phylogenetic group are influenced by a unique mosaic of factors that is difficult to summarize quantitatively. The results of the study provide cautions as well as encouragements for the estimation of body mass for fossil species that have no adaptively similar living relatives.
