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 15 Uhr im Museum am Löwentor statt und werden über Zoomübertragen. Wir freuen uns über rege Teilnahme vor Ort oder online!

Genomic Perspectives on African Shrews: Evolutionary History, Diversity, and Speciation Patterns in Crocidura
Malahat Dianat, Masaryk University, Brno
The diverse geomorphology and climatic fluctuations of Africa provide a unique opportunity to study the evolutionary history, biodiversity, and speciation of small mammals, particularly in sub-Saharan Africa. I focused on the genetic diversityand taxonomy of Afrotropical white-toothed shrews (genus Crocidura).Using ddRAD sequencing, I examined the phylogenetic relationships of Crociduraspecies across various habitats. High species diversity was identified, newcandidate species were proposed, and taxonomic adjustments were made. EasternAfromontane shrews likely originated in the Ethiopian Highlands, dispersingsouthward, while savanna species diversified during Pleistocene grasslandcycles. African giant shrews (C. olivieri) recently expanded its range, withmitochondrial introgression occurring during population expansion. This studyhighlights Crocidura as a model for future research onmitochondrial-nuclear discordance.
As usual, we will also broadcast via zoom for those who can not join in person: https://zoom.us/j/94510498226
