Si cycling in a forest biogeosystem – the importance of transient state biogenic Si pools
The relevance of biological Si cycling for dissolved silica (DSi) export from terrestrial biogeosystems is still in debate. Even in systems showing a high content of weatherable minerals, likeExpand

Biodiversity development of terrestrial testate amoebae: is there any succession at all?
Heterotrophic protists (e.g. testate amoebae) play an important part in primary succession because these unicellular organisms occur immediately at newly exposed land surfaces in high abundances andExpand

Dynamics and drivers of the protozoic Si pool along a 10-year chronosequence of initial ecosystem states
Abstract The size and dynamics of biogenic silicon (BSi) pools influence silicon (Si) fluxes from terrestrial to aquatic ecosystems. The research focus up to now was on the role of plants in SiExpand
