Abstract: This study synthesises research exploring how climate change-induced hydrological extremes influence the structure, species composition, and functional diversity of benthic diatom assemblages in watercourses of varying sizes (from 10 km² to approximately 10,000 km² catchment areas), across multiple temporal (1-15 years) and spatial (Pannonian and Mediterranean) scales. The focus is particularly on intermittent small streams in the Carpathian Basin, encompassing both the Great Hungarian Plain and the Transdanubian region. Rather than treating drying as a separate event, these investigations approach it as a gradual process composed of successive hydrological phases - flowing, standing, and dry - each with distinct impacts on assemblage structure and diversity. The findings contribute to a deeper understanding of how benthic diatom assemblages respond to climatic extremes, offering insight into ecosystem resilience and vulnerability under ongoing environmental change. This work is dedicated to Professor Judit Padisák - as a gesture of gratitude and a tribute to a distant yet ever-supportive mentor, whose early encouragement and continued watchful presence have been invaluable throughout this journey.Keywords: climate change, biodiversity, benthic algae, composition, intermittent streams, large rivers
