Collective volume that brings together 42 contributions dedicated to Maria Rosa Miracle, who passed away on May 28, 2017 in Valencia, at the age of 72, when she was still active as professor emeritus at the Universitat de València. During her nearly five decades of research and teaching, she became a globally influential limnologist, as her lines of research paved the way for new interdisciplinary topics, some of which are discussed in this tribute book. Shortly after her death, the Iberian Association of Limnology dedicated a special issue of its journal 'Limnetica' to her, to which she was always linked as author, reviewer or editor. Former students, colleagues and collaborators sign the texts of this volume, most of which had already been published in the journal. They seek answers to some of the puzzling limnological questions posed by Maria Rosa and take up some of the unfinished studies of her last months of research activity, in which she left a wealth of research data that may be published in the near future following her ideas and guidelines.
