Direkt am Puls der Wissenschaft: in unserem Wissenschaftskolloquium werden aktuelle Forschungsarbeiten aus dem Naturkundemuseum Stuttgart, aber auch von (internationalen) Partnerinstitutionen vorgestellt. Das Kolloquium dient dem wissenschaftlichen Austausch unter Forschenden und allen Forschungsinteressierten. Die Vorträge in englischer Sprache finden regelmäßig alle 14 Tage dienstags um 16 Uhr im Museum am Löwentor statt und werden über Zoom übertragen. Wir freuen uns über rege Teilnahme vor Ort oder online!

Where science meets conservation – population genetics of the native freshwater mussel Unio crassus s. l.
Dr. Ira Richling, Naturkundemuseum Stuttgart
The Thick Shelled River Mussel Unio crassus s. l. is one of the most endangered large freshwater mussel species in Europe. Providing a baseline for the conversation of genetic diversity, potential reintroduction and enforcement of populations, the genetic constitution of almost all surviving populations of Unio nanus in Southwestern Germany was investigated. The sampling covered the drainage systems of Rhine, upper Danube and Weser. Molecular methods applied included sequencing the maternal mitochondrial COI haplotypes, analyses of microsatellites as well as Next Generation Sequencing with RADseq.
Overall, the different datasets revealed similar patterns and results regarding genetic diversity, diversification and connectivity of populations as well as the differentiation across the range with an expectedly diverging depth of resolution for the three methods at the different levels of analysis from individuals to drainage systems.
Results presented will focus on the RADseq data and as outlook a comparison will be given to the results on the populations of Unio crassus from Northern Germany.
The project in Baden-Württemberg was supported by the Stiftung Naturschutzfond Baden-Württemberg and the „Fischereiabgabe des Landes“ and for Northern Germany by the EU project “LIFE Bachmuschel” and Stiftung Naturschutzfonds Brandenburg.
As usual, we will also broadcast via zoom for those who can not join in person: https://zoom.us/j/94510498226
