Flourish or flush : effects of simulated extreme rainfall events on **Sphagnum**-dwelling testate amoebae in a subarctic bog (Abisko, Sweden)
Abstract: Extreme precipitation events are recognised as important drivers of ecosystem responses to climate change and can considerably affect high-latitude ombrotrophic bogs. Therefore, understanding the relationships between increased rainfall and the biotic components of these ecosystems is nece...
