However, this effect may be related to the ecological differentiation between coexisting species, often expressed as either functional diversity (FD; diversity in traits) or phylogenetic diversity (PD; diversity in phylogenetic ancestry) within plant communities. Evidence for the independent and combined role of FD and PD on ecosystem functions is generally missing, as measures of FD and PD are usually confounded in empirical studies. Methods To solve this challenge we used an ad-hoc designed biodiversity experiment, with sown meadow plant communities forming independent combinations of FD and PD (low/low, low/high, high/low, high/high values, plus monocultures) and used ionexchange membranes to monitor changes in soil N (i.e. NH4 +-N and NO3 −-N) availability through time (four sampling times per year; i.e. seasonality). Results Our results showed a positive diversity effect for soil NH4 +-N, with mixture communities yielding higher levels of NH4 +-N than the corresponding monocultures. Within mixtures, communities with combinations of both high FD and PD ... |
