| Popis: | Background and aims Due to global warming, it is to be expected that mangroves will move north- and southwards and enter salt marshes, which will then be enriched with mangrove-derived organic compounds. Little is known about the effects that tannins, which are abundantly present in leaf litter of Rhizophora mangle, will have on the biogeochemical cycles in salt marsh soils. Methods In microcosms, soil from a Distichlis spicata salt marsh was enriched with R. mangle-derived leaf powder (LP), crude condensed tannins (CCT) and purified condensed tannins (PCT), or with commercially available tannic acid (TA). Each treatment received a fixed amount of tannins, i.e. 10 mg /g dry soil. Due to the enrichment with tannins in each fraction, the amount of carbon added increased from C |
