This photo shows Mauremys annamensis, Mauremys sinensis and Cyclemys pulchristriata in the local trade in central Vietnam PHOTO CREDIT: TIM MCCORMACK/ATP Genetic and Shell Shape Variability in Mauremys annamensis Many turtle species, especially within the genus Geoemydidae, are endangered or almost extinct due to habitat destruction and a phenomenon known as the “Asian Turtle Crisis” – the often illegal trafficking in turtles to satisfy the high demand by Chinese markets for turtle meat for consumption and the use of turtle parts in traditional Chinese medicine. The situation is further complicated by frequent hybridization within this family. Hybrids among species, and even among genera, are known both from captivity and in nature. Several hybrids had been wrongly described as new species. The Vietnamese Pond Turtle (Mauremys annamensis), a species almost extinct in the Tomáš Protiva wild and with a small population in captivity, is extremely threatened by possible hybridization. Hybridization among Mauremys annamensis, M. mutica, M. sinensis, M. nigricans, Cuora amboinensis and C. trifasciata has been reported both from captivity and in the wild. The species which is genetically closest, ecologically similar, and thus most probable as a partner for hybridization is M. mutica, which also inhabits the distribution area of M. annamensis. It’s crucial to focus protection and repatriation efforts only on pure specimens of M. annamensis and not on hybrids. Genetic studies carried out in the United States with samples of captive specimens found that specimens of M. annamensis form two groups: One group consists of pure animals, the second is formed by hybrids of M. annamensis and some closely related species. These particular hybrids look physically like M. mutica, according to external morphology and coloration, so it is not possible to confuse them with pure M. annamensis. According to mitochondrial genes (genes inherited only in the female lineage) there are two closely related groups of pure M. annamensis. These results suggest that in the ancient history of this species, there were either two isolated populations, or perhaps nearly related species, which formed M. annamensis as we know it today. Genetic distance between these two groups is small and there is no reason for distinguishing them as separate taxonomical units at the moment. It is advisable to keep them separated in the case of repatriation as there may be possible reclassification in the future. Recent genetic research conducted on the captive European population shows that all specimens classified as M. annamensis – according to the size, shell shape, and coloration – are most probably not hybrids. Repatriation to the original distribution areas of this species is possible and without risk of contaminating native populations with hybrids. Our research of shell shape variability using the method of geometric morphometrics within M. annamensis shows that there are differences between two mitochondrial groups in the shell shape of carapace and plastron. Our work further supports distinction of these two groups and importance of their separation in breeding facilities. It is possible to determine turtle species using this fast, cheap, and non-invasive method of shell shape identification and differentiation rather than through the use of genetic testing.

TSA EUROPE MUENSTER ZOO Successful Breeding Efforts at International Center for the Conservation of Turtles (IZS) at Muenster Zoo Result in Rare Hatchings An adult Cuora cyclornata at the Muenster Zoo. PHOTO CREDIT: HENK ZWARTEPOORTE Dr. Martina Raffel and Elmar Meier TABLE 1: OFFSPRING HATCHED AT IZS IN 2014 Focused breeding efforts at the International Center for the Conservation of Turtles (IZS) resulted in a record fourteen hatchlings of the Yellow-headed Box Turtle (Cuora aurocapitata). Additionally, the first-ever two hatchlings of the Central Vietnamese Three-striped Box Turtle (Cuora cyclornata cyclornata) outside of their native Southeast Asia were also produced. In regard to the total number of hatchlings, 2014 has been rather an average year for the IZS at the Muenster Zoo – with 38 offspring in 11 species hatched (see table below). Furthermore, for the first time, female offspring in Cuora aurocaptitata and McCord’s Box Turtle (Cuora mccordi) produced hatchlings; making these the first ever reported halfway F2-generation in these species. The female Zhou’s Box Turtle (Cuora zhoui) offspring, as reported in 2013, produced another clutch in 2014, and was even joined by a second female hatched in captivity. The strategy to establish and build assurance colonies by transferring various turtles to places such as the Rotterdam Zoo, Nordens Ark, and with several private turtle keepers, has seen remarkable success and progress as the breeding loan turtles quickly started to reproduce. Additional institutions and private persons have been included in the ESF studbooks and will hopefully add up to more overall success in the future.
