The aim of the collection of DNA and environmental samples is to preserve and manage extracted samples of DNA and tissue, as well as extracted environmental samples, for scientific purposes. In order to study nature and to understand and prognosticate global changes, researchers in all fields of science that investigate living nature engage in systematic and consistent collection of samples. To preserve the extracted samples of DNA and tissue, as well as extracted environmental samples, and to make them easily accessible to stakeholders in a machine-readable form, the samples need to be preserved and managed according to specific requirements. The DNA bank is part of the Global Genome Biodiversity Network (GGBN) which was founded in 2011. The network provides a technically optimized DNA collection service facility for all biological research accessible via one central web portal. The network promotes deposition of well documented reference DNA samples after project completion or data publication from scientists of other universities and institutions.
