For the curatorial staff, I think Frankfurt, again, was the first one to create the position of a volunteer curator. That was a position with a very, very low salary that was just for one year. Under special circumstances, one could add a second year but definitely not more. And this volunteer curator, not only followed the work of all the other curators, but of all departments. And I think that’s a very, very, very important solution to get young zoo biologists with firsthand experience.
