German-Vietnamese long-term cooperation between the cologne zoo and the institute of ecology and biological resources in terms of herpetodiversity research and conservation

The outcomes of our integrative taxonomic analyses, viz. the combination of morphological and molecular datasets are publications of herpetofaunal lists for such regions, reserves or provinces, including first regional or country records of species or even new species discoveries (Ziegler & Nguyen 2015). Also species group revisions and positioning of poorly known or newly described species in phylogenetic trees help to better understand diversity and uncover cryptic, viz. hidden diversity.
