Veronika Kasper wrote her master thesis under supervision of Thomas Hein about Microphytobenthos (MPB), small algae attached to a substrate. It plays a major role in lotic ecosystems and is often affected by multiple stressors. Thermopeaking (TP) combines stress of sudden flow velocity increase (Hydropeaking) and abrupt water temperature alteration. Although this effect is prevalent in alpine regions, studies concerning its influence on MPB are a critical knowledge gap. Therefore the aim of this project was to provide knowledge about the impact of TP on MPB, considering as well successional and habitat aspects.
