Trade Data and Some Comments On the Distribution of Mauremys annamensis (Siebenrock, 1903).
Asiatic Herpetological Research 10: 110-113.
This trade survey of Annam Pond Turtle reveals that this species is likely to have larger distribution than previously thought. The records in the trade in Quy Nhon and Ho Chi Minh City suggest its range could extend much further south. In addition, given the one way south-north trade route, the absence of Mauremys mutica in the trade south of Hai Van Pass and the reported absence of M. annamensis in the trade north of the Pass support the hypothesis that the Pass is the natural barrier for the two species ranges. This hypothesis combined with the long existence of the Pass might indicate that the speciation between the two species happened when their ancestors dispersed across the Pass, and were subsequently isolated, by the means of rafting or walking through narrow land strip emerged during the low sea level period. In terms of conservation, M. annamensis has become much rarer even in the trade, suggesting immediate conservation measures to protect it.
