Amilcare is recognized as one of the “fathers” of ecohydrology. His groundbreaking research about the interactions among climate, soil, and vegetation; the ecohydrologic drivers of carbon and nitrogen cycles; and the complex relationship between soil moisture and microbial activity are landmark studies. And these are only examples of how his work has contributed decisively to move hydrology’s boundaries toward important and fascinating new horizons. I’d like to recall here also his strong interest in fluid mechanics. Amilcare’s interest in a variety of new research areas speaks for his intellectual curiosity and love for knowledge, which have allowed him to break down artificial barriers between disciplines and unleash his creativity.

Amilcare has been an exceptional mentor for students and postdocs, as testified by a remarkable placement record in faculty positions at major research institutions around the world. Many of us have appreciated his generosity of ideas and time. He mentors junior scientists, collaborates with colleagues, and serves the science community with energy and the same youthful and contagious enthusiasm as when I first met him many years ago.

I have known Amilcare for almost 3 decades. I was lucky to see him grow as a scientist, showing from the start his great originality and depth of thought, capacity to grasp the essential aspects of the questions, and his genuine passion for study and research. These are all qualities he has kept, refined, and nurtured over the years. We expect from him still so many good ideas and new topics.
