Patterns and driving factors of ecological stoichiometry in system of deadwood and soil in mountains forest ecosystem.

The aim of our research was to identify the factors that most strongly determine the C, N and P cycles in the deadwood-soil system in mountains forest ecosystems. We assumed that the climatic conditions resulting from the location in the altitude gradient and rate of deadwood decomposition most strongly determine the C/N/P stoichiometry. A climosequence approach comprising north (N) and south (S) exposure along the altitudinal gradient (600, 800, 1000 and 1200 m a.

Soil biochemical properties and stabilisation of soil organic matter in relation to deadwood of different species.

Despite the increasing number of studies on deadwood, we still have limited knowledge of its dynamics. The aim of this study was to examine the effect of deadwood on the biochemical properties of soil and stabilisation of soil organic matter (SOM). The investigation was carried out in the Czarna Rózga Reserve in Central Poland.
