“…Belowground, the much lower root decomposition rates (R. taedigera: 0.13 ± 0.02 years -1 ; C. panamensis: 0.17 ± 0.01 years -1 ) ( Fig. 3; ESM_4) are comparable to those reported for wood and roots in temperate ecosystems (Tripathi et al 2006;Trofymow et al 2002). The leaf litter decay rates presented in this study are comparable to decay rates shown for a range of peat swamp tree species in Malaysia (Yule and Gomez 2008).…”

Litter decomposition is an important control on carbon accumulation in tropical peatlands. We investigated the contribution of different litter tissues from two peatland tree species (Raphia taedigera and Campnosperma panamensis) to peat formation in four lowland tropical peatlands in the Republic of Panama. Leaves, stems, and roots decomposed at different rates; with roots being the slowest to decompose among tissues. The position of litter in the peat profile strongly influenced the decomposition rate of all tissue types. Roots decomposed up to five times faster at the surface than at 50 cm depth. Molecular characterization of litter and peat profiles by tetramethylammoniumpyrolysis-gas chromatography-mass spectrometry (TMAH-Py-GC/MS) revealed that the peat is formed predominantly of decomposed roots and stems, as indicated by the high lignin, low methylated fatty acids and carbohydrate concentrations in these litter types. Taken together, these data demonstrate that roots play a fundamental role in the formation of lowland Neotropical peatlands.

“…Later stages of decomposition are thought to be more heavily influenced by interactions between N content and chemical form and components of root cell walls including lignin, cellulose, and suberin (John et al 2002;Yang et al 2004;Tripathi et al 2006;Lemma et al 2007). Increases in soil N availability can suppress decomposition of phenolic compounds contained within cell walls (Berg 2000;Wang et al 2004).…”

Background The predictive power of climate models is limited by an incomplete understanding of the controls on fine root decomposition and thus belowground carbon cycling. To more accurately model rates of decay, fine root heterogeneity needs to be addressed in fine root decomposition studies. Branching order integrates both structural and chemical properties that are important in indicating litter quality and decay rate. Scope We discuss current views on the controls and patterns of fine root decomposition in combination with recent findings related to the effects of branching order and mycorrhizal decomposition. We examine the counterintuitive finding that nitrogen rich, lower order roots decompose more slowly than woody, higher order roots in temperate and subtropical forests. ConclusionsWe posit that slower decomposition of first and second compared to higher order roots might be caused by the poor carbon quality associated with higher concentrations of phenols in lower order roots or by inhibition of saprophytes by the mycorrhizal fungi that often preferentially inhabit these roots. Alternatively, apparent recalcitrance of lower order roots could be an experimental artifact caused by severing pre-mortem mycelial connections during sample processing, or exclusion of animals that graze fungal structures by the small mesh sizes characteristic of litterbags. To better predict the residence time of the carbon contained in the entire fine root pool, existing methods should be applied to individual root orders when practical. New methods for characterizing decomposition of undisturbed roots that have senesced naturally are greatly needed.

“…Bamboos also affect seed dispersal patterns, influencing forest regeneration on its early stages (Rother et al, 2009). Forest soils and nutrient cycling are also affected by high bamboo dominance that may have soils and litter poorer in some nutrients (Veblen, 1982;Tripathi et al, 2006).…”
