Dear Members, unfortunately we have a sad news to share with you. This is the accidental death of a young acarologist, very active in the study of the oribatids, Dr. Ekaterina Sidorchuk, from Russia. In the words of colleagues who worked with her, Katya was “vibrant, perceptive, brilliant colleague, and good friend to many”, a “young, kind and charming person, and a brilliant and exceptional researcher” .Every year we learned about the loss of acarologists and that is always a sad fact. In this case, the fact of being an accidental death, of a young researcher, is doubly painful. A great loss for the global acarology. We accompany your family in those sad moments.
