“…Like the other species of pangolins and despite protection under national legislation, African common pangolins are subject to (i) an unprecedented rise of hunting pressure at the regional scale and (ii) a growing international trade for food and Chinese traditional medicine (Bräutigam et al . ; Sodeinde & Adedipe ; Yiming & Dianmo ; Luo et al . ; Pantel & Chin ; Baker ; Zhou et al .…”

“…Six cryptic lineages in the African common pangolin: implication for the molecular tracing of its trade Unsustainable bushmeat hunting in the tropics is considered a primary driver of extinction (Fa et al 2002), notably in African rainforests (Abernethy et al 2013). Like the other species of pangolins and despite protection under national legislation, African common pangolins are subject to (i) an unprecedented rise of hunting pressure at the regional scale and (ii) a growing international trade for food and Chinese traditional medicine (Br€ autigam et al 1994;Sodeinde & Adedipe 1994;Yiming & Dianmo 1998;Luo et al 2009;Pantel & Chin 2009;Baker 2014;Zhou et al 2014;Soewu & Sodeinde 2015). In 2014, 6.4 tons of pangolin scales were seized through international trade, which represents more than the sum of all the previous years of seizure since 2000 (Challender & Hywood 2012).…”

Phylogeography of the heavily poached African common pangolin (Pholidota, Manis tricuspis) reveals six cryptic lineages as traceable signatures of Pleistocene diversification

Knowledge on faunal diversification in African rainforests remains scarce. We used phylogeography to assess (i) the role of Pleistocene climatic oscillations in the diversification of the African common pangolin (Manis tricuspis) and (ii) the utility of our multilocus approach for taxonomic delineation and trade tracing of this heavily poached species. We sequenced 101 individuals for two mitochondrial DNA (mtDNA), two nuclear DNA and one Y-borne gene fragments (totalizing 2602 bp). We used a time-calibrated, Bayesian inference phylogenetic framework and conducted character-based, genetic and phylogenetic delineation of species hypotheses within African common pangolins. We identified six geographic lineages partitioned into western Africa, Ghana, the Dahomey Gap, western central Africa, Gabon and central Africa, all diverging during the Middle to Late Pleistocene. MtDNA (cytochrome b + control region) was the sole locus to provide diagnostic characters for each of the six lineages. Tree-based Bayesian delimitation methods using single- and multilocus approaches gave high support for 'species' level recognition of the six African common pangolin lineages. Although the diversification of African common pangolins occurred during Pleistocene cyclical glaciations, causative correlation with traditional rainforest refugia and riverine barriers in Africa was not straightforward. We conclude on the existence of six cryptic lineages within African common pangolins, which might be of major relevance for future conservation strategies. The high discriminative power of the mtDNA markers used in this study should allow an efficient molecular tracing of the regional origin of African common pangolin seizures.

“…Temminck's ground pangolin is one of eight extant pangolin species (Heath, ). It is distributed throughout most of eastern and southern Africa (Sodeinde and Adedipe, ) and is the only pangolin species found in southern Africa (Bräutigam et al, ). The ground pangolin is a myrmecophagous mammal (Sweeney, ; Swart, ) that inhabits savannah and woodland areas (Kingdon, ; Richer et al, ).…”

Temminck's ground pangolin is the only pangolin present in South Africa. It is a myrmecophagous mammal with a bipedal gait. The thoracic limbs are used to break open ant nests, dig for food, and expand previously occupied burrows. This study describes the osteology and radiological anatomy of the thoracic limbs of this threatened species. Thoracic limbs from four Temminck's ground pangolins, which succumbed from electrocution or natural causes, were digitally radiographed in situ. The individual bones were then cleaned, described and digitally radiographed. The skeleton of the thoracic limbs revealed a similar number and arrangement of bones compared to that of domestic carnivores. The bones were robust and displayed numerous open epiphyseal lines. The latter provide an estimate of sexual maturity and should not be confused with fractures in injured ground pangolins. The scapula was broad and triangular-shaped. The humerus displayed a massive medial epicondyle. The radius and ulna were similarly sized, and displayed a broad radial trochlea and large olecranon tuber, respectively. The manus was composed of seven carpal bones, five short metacarpal bones and five digits of which the three central digits were the best developed. The unguicular process of the distal phalanx was bifid and elongated. The osteological characteristics indicate that the thoracic limbs of Temminck's ground pangolin are specifically adapted for protraction and retraction, strong elbow extension, flexion of the carpus and digits as well as pronation and supination of the antebrachium, as opposed to weight-bearing. These functions are likewise documented for other scratch-digging species. Anat Rec, 301:624-635, 2018. © 2017 Wiley Periodicals, Inc.

Habitat Selection by Chinese Pangolin (Manis pentadactyla) in Winter in Dawuling Natural Reserve

Habitat selection by Chinese pangolin (Manis pentadactyla) in winter was studied in Dawuling Natural Reserve, Maoming City of Guangdong Province, China, from December 1999 through February 2001.The objective of this study was to determine the pangolin's habitat requirement in winter during poor environmental conditions. The dominant habitat of this Reserve was classified into 4 types, i.e. mixed coniferous and broadleaf forest (MCBF), evergreen broadleaf forest (EBF), coniferous forest (CF) and shrub forest (SF). The results showed that the ranking of vegetation types selected by pangolins in winter was MCBF > SF > EBF > CF. Pangolins preferred MCBF, and avoided CF. The environmental factors preferred by pangolins in winter were 30°-60° steep slopes, middle of slopes and bottom of slopes, sunny slopes, dis-KEY WORDS Dawuling Natural Reserve, pangolin, Manis pentadactyla, habitat selection.

The surroundings factors avoided by pangolins were sharp slopes steeper than 60° or gentle slopes less than 30°, shady slopes, distance from human disturbance source within 1 000 m, dense (71 % -100 %) or sparse (0 % -30 %) closure of arbor canopy, medium or lower coverage (0 % -50 %) of undergrowth, and the top of the slope. Pangolins preferred south-facing burrow entrances with thick cover, and avoided north-facing burrow entrances with bare or poor shelter. The thick layer of shrub and herbs growing under the tree canopy appeared to be especially important to pangolins during winter.
