Title
Landscape cultivation alters signature in terrestrial ecosystems
Author
Abstract
Despite increasing recognition of the relevance of biological cycling for Si cycling in ecosystems and for Si export from soils to fluvial systems, effects of human cultivation on the Si cycle are still relatively understudied. Here we examined stable Si isotope (delta Si-30) signatures in soil water samples across a temperate land use gradient. We show that - independent of geological and climatological variation - there is a depletion in light isotopes in soil water of intensive croplands and managed grasslands relative to native forests. Furthermore, our data suggest a divergence in delta Si-30 signatures along the land use change gradient, highlighting the imprint of vegetation cover, human cultivation and intensity of disturbance on delta Si-30 patterns, on top of more conventionally acknowledged drivers (i.e. mineralogy and climate).
