Fecha de publicación: | may-2016 | Editor: | John Wiley & Sons | Citación: | Ecology Letters 19: 554-563 (2016) | Resumen: | Climate, litter quality and decomposers drive litter decomposition. However, little is known about whether their relative contribution changes at different decomposition stages. To fill this gap, we evaluated the relative importance of leaf litter polyphenols, decomposer communities and soil moisture for litter C and N loss at different stages throughout the decomposition process. Although both microbial and nematode communities regulated litter C and N loss in the early decomposition stages, soil moisture and legacy effects of initial differences in litter quality played a major role in the late stages of the process. Our results provide strong evidence for substantial shifts in how biotic and abiotic factors control litter C and N dynamics during decomposition. Taking into account such temporal dynamics will increase the predictive power of decomposition models that are currently limited by a single-pool approach applying control variables uniformly to the entire decay process. | Versión del editor: | https://doi.org/10.1111/ele.12590 | URI: | http://hdl.handle.net/10261/342049 | DOI: | 10.1111/ele.12590 | ISSN: | 1461-023X | E-ISSN: | 1461-0248 |
