300145 UE Entwicklungsbiologie mariner Evertebraten in Villefranche-sur-Mer (2023S)

In this practical course at the Marine Station in Villefranche / Cote d'Azur, we will address questions of developmental biology of marine invertebrates available at the station (cnidarians, polychaetes, sea urchins, urochordates). The development will be studied by manipulation of key signaling pathways, followed by phenotypic and molecular analysis. In addition, we will benefit from the exceptional fauna in the plancton around Villefranche and we will examine samples of plancton and determine larvae and species of various animal groups. The student will get an understanding of the development of several marine model species (sea urchin, ascidians, hydrozoans) and do experiments investigating the regulation of developmental processes and of body plans. They aquire an understanding of hte biodiversity of planctonic life.
