- Abstract: Temminck's pangolin ( Smutsia temminckii ) is a threatened mammal found in southern and eastern Africa. It is the most widely distributed African pangolin species yet is listed as Vulnerable on the IUCN Red List due to a projected population decline of 30%–40% within the next three generations. This species' secretive, predominantly nocturnal behaviour and generally low population densities make it difficult to directly assess its distribution, and thus, alternative methods are required. Furthermore, many historical and some contemporary records of this species exist from outside of its accepted range, suggesting that the distribution may be greater than currently accepted, although the validity of these records has never been assessed. We used MaxEnt modelling to evaluate the most likely distribution of S. temminckii in South Africa and compared the past and present distribution of the species, as well as assessed the probable validity of the questionable records. Our results suggest that one of the questionable historical museum records is probably valid, while the other may refer to an erroneous collecting locality. At least some contemporary sightings which were originally deemed questionable are probably valid, while others should be treated as dubious until supporting information to validate their authenticity becomes available. Résumé: Le pangolin de Temminck ( Smutsia temminckii ) est un mammifère menacé qui se trouve en Afrique australe et orientale.

Résumé: Le pangolin de Temminck ( Smutsia temminckii ) est un mammifère menacé qui se trouve en Afrique australe et orientale. Il s'agit de l'espèce de pangolin africain la plus abondante, et pourtant, elle est désignée comme vulnérable sur la liste rouge de l'UICN en raison d'un déclin de population de 30 à 40% prévu au cours des trois prochaines générations. Le comportement discret et principalement nocturne de cette espèce et sa densité de population généralement faible rendent difficile l'évaluation directe de sa répartition et des méthodes alternatives sont donc nécessaires. En outre, de nombreuses mentions historiques et certaines mentions contemporaines faisant état de la présence de cette espèce à l'extérieur de son aire de répartition admise existent, ce qui suggère que la répartition réelle de cet espèce pourrait être plus étendue que celle actuellement admise, bien que la validité de ces mentions n'ait jamais été déterminée. Nous avons utilisé la modélisation MaxEnt pour déterminer la répartition la plus probable de l'espèce S. temminckii en Afrique du Sud et comparé la répartition passée et actuelle de l'espèce, ainsi que la validité probable des mentions d'occurrence douteuses. Nos résultats suggèrent que l'une des mentions d'occurrence douteuses de musée est probablement valide, tandis que l'autre peut faire référence à une localité de collecte erronée. Au moins certaines observations contemporaines, qui étaient à l'origine considérées comme douteuses, sont probablement valides, tandis que d'autres devraient être considérées comme douteuses jusqu'à ce que des informations complémentaires permettant de valider leur authenticité soient disponibles. … (more)
