We measure the fine scale spatial patterns of ecosystem functional attributes (e.g. biomass and soil respiration) together with the patterns of diversity in natural grasslands. The spatial and temporal variability of these attributes refers to the reliability of the ecosystem. Low relative variability means high predictability, high consistency, i.e. high reliability. According to our hypothesis the highest reliability appears in community of high structural complexity which are not only rich in species but also well organized in space. In this way we are searching for early warning signals to managers about processes threatening ecosystem services in the future.
