“…The large root biomass and litter production in M. macclurei plantation enhanced its soil organic carbon contents. Broadleaved tree species increase litter production and nutrient returns, and are helpful to restore soil fertility of degraded monoculture forests (Wang et al, 2008). The changes in the carbon stocks of the soils in the different forest types might also reflect the differences in quantity and quality of above-and below-ground litter inputs, litter carbon decay (Mo et al, 2002), and root biomass carbon.…”

“…Litter decomposition is the main process in ecosystems to circulate nutrients (van Vuuren et al 1993, Vitousek et al 1994, Aerts and Chapin 2000, Wang et al 2008, Klotzbücher et al 2011, supply organic and inorganic elements (Wang et al 2008), sustain soil fertility (Koukoura et al 2003), release carbon dioxide to the atmosphere gii, had slow decomposition. The mass loss of each litter species was negatively correlated with the cellulose (R 2 = 0.690, P = 0.081) and lignin (R 2 = 0.939, P = 0.007) content.…”

Litter decomposition is an important process in terrestrial ecosystem. However, studies on decomposition are rare, especially in evergreen broadleaf trees. We collected the leaf litter of five evergreen broadleaf trees (Daphniphyllum macropodum, Dendropanax morbifera, Castanopsis cuspidata var. thunbergii, Machilus thunbergii and Quercus acuta), and carried out a decomposition experiment using the litterbag method in Ju-do, Wando-gun, Korea for 731 days from December 25, 2011 to December 25, 2013 ). The decomposition of litter was positively influenced by thermal climate such as accumulated mean daily air temperature (year day index) and precipitation, as well as by physical characteristics such as thickness (R 2 =0.939, P = 0.007) and specific leaf area (SLA) (R 2 = 0.964, P = 0.003). The characteristics of chemical composition such as lignin (R 2 = 0.939, P = 0.007) and water-soluble materials (R 2 = 0.898, P = 0.014) showed significant correlations with litter decomposition. However, the nutrients in litter showed complicated species-specific trends. The litter of D. macropodum and D. morbifera had fast decomposition despite their low nitrogen concentration and high C/N ratio. This means that the litter decomposition was more strongly affected by physical characteristics than chemical composition and nutrient content. On the other hand, the litter of Q. acuta which had the slowest decay rate had a high amount of N and low C/N ratio. Thus, the decomposition of Q. acuta litter was more affected by the P content of the litter than the N content, although all litter had similar physical characteristics.

ARTíCULOS Producción y descomposición de hojarasca en la selva ombrófila mixta en el sur de BrasilLitter production and decomposition in a mixed araucaria forest in the south of Brazil SUMMARYThe aim of the present work was to evaluate the litter production and decomposition in a mixed araucaria forest in the south of Brazil. The vegetation of the area is characterized by two forest types: forest type I, with the upper canopy dominated by Araucaria angustifolia; and forest type II, with higher diversity of tree species, predominantly broad-leafed species in the dominant canopy strata. To evaluate the litter production, 20 wood traps with 0.25 m 2 of surface were installed. Ten samples of 0.25 m 2 were monthly collected from the litter layer. Litter decomposition was evaluated from the instantaneous decay rate (K). The average of three years concluded that litter production did not differ significantly in the two types of forest studied: 7,661 kg ha -1 year -1 in forest type I and 8,624 kg ha -1 year -1 in forest type II. The months with the highest production in forest type II were correlated with periods of higher precipitation (spring and summer). The litter layer was significantly different for the two forest types, being heavier in forest type I with values of 9,924 kg ha -1 and 7,906 kg ha -1 for forest type II. The area with predominance of Araucaria angustifolia presented a slower rate of litter decomposition and nutrient release.Key words: litter production, decay rate, Araucaria angustifolia. RESUMENEl objetivo del presente trabajo fue evaluar la producción y descomposición de hojarasca de la selva ombrófila mixta en el sur de Brasil. La vegetación del área presentó dos tipos forestales: I, cuyo dosel superior estaba dominado por Araucaria angustifolia y II, con mayor diversidad de especies arbóreas predominando latifoliadas en el estrato superior. Para evaluar la producción de hojarasca fueron instalados 20 colectores de 0,25 m 2 de superficie. Para la cuantificación del mantillo, mensualmente se retiraron 10 muestras de 0,25 m 2 . La descomposición de la hojarasca fue determinada a partir de la tasa instantánea de descomposición (K). De los resultados observados en tres años de estudio se concluye que la producción de hojarasca no difirió significativamente en los dos tipos forestales estudiados, con 7.661 kg ha -1 año -1 en el tipo forestal I y 8.624 kg ha -1 año -1 en el tipo forestal II. Los meses de mayor cantidad de hojarasca en el tipo forestal II estuvieron correlacionados con períodos de mayores precipitaciones (primavera y verano). Para el mantillo hubo diferencias significativas entre los dos tipos forestales, presentando mayor cantidad el tipo forestal I con valores de 9.924 kg ha -1 y de 7.906 kg ha -1 el tipo forestal II. El bosque con predominio de Araucaria angustifolia presentó una tasa de descomposición y una liberación de nutrientes más lentas.Palabras clave: producción hojarasca, tasa de descomposición, Araucaria angustifolia.
