Storage effects: the relationship between the hydrological dynamics of small infield pools and plant functional groups

Small infield pools are important habitats. But, the properties that make them attractive for several wetland species as well as the traits which allow species to survive in such high dynamical systems are largely unknown. I investigated the habitat quality with a time series model which requires only the climatic time series evapotranspiration and precipitation and an observed daily water level time series. Further, I developed transfer function to describe mean drying up frequencies and mean spring high water level out of short time measurements. The results show a decrease in the minimum water level and an increase in the yearly water dynamic caused by rising temperatures in the study area, indicating a change in the habitat quality by climate changes. I developed a new method to calculate the responses of plant species with certain traits according to the habitat quality. The resulting PFGs are characterised by different storage, competition, and adaptation strategies.
