Aboveground litterfall in Eurasian forests

Journal of Forestry Research, 2003
With a data set of Eurasian forest litter fall based on 471 stands, annual litterfall was estimated to be 6.53 Pg dm·a−1 (1 Pg=1015 g;dm, dry matter) in Eurasian forests, of which more than half occurred in tropical and subtropical forests, and a third in the boreal area.

Measuring Litterfall and Branchfall

2008
Trees capture CO2 from the air, return a large fraction to the atmosphere via autotrophic respiration, produce live tissues from assimilated carbon, and return expired tissues to the soil via the process of senescence. Methods described in this chapter deal with the measurements of the flow of above-ground solid carbon-based material to the forest ...

Microsite heterogeneity in litterfall risk to seedlings

Austral Ecology, 2005
Abstract  Litterfall is an important cause of damage and mortality to seedlings in many forest ecosystems. This study is the first to investigate the contribution of variable risk of litterfall damage to microsite heterogeneity. Two hundred artificial seedlings were ‘planted’ in the ground at 2‐m intervals along transects in each of two New Zealand ...

Changes in Litterfall Along a Gradient in Altitude

The Journal of Ecology, 1987
(1) Above-ground litterfall was measured in twenty-five stands along a 700 m gradient in altitude in the White Mountains, New Hampshire, U.S.A. Vegetation changed along this gradient from deciduous forest, to coniferous forest, to krummholz. (2) The pattern of change with altitude for annual deposition of deciduous leaf, total leaf, and total fine ...

Mixed models applied to the litterfall productivity

2014
Se propone una metodología para realizar un ajuste de un modelo lineal mixto incorporando una estructura de varianza y de correlación serial adecuada partiendo desde el modelo de regresión lineal clásico siguiendo la estrategia de Zuur et al. (2009). Se utilizan diferentes gráficos de diagnóstico de los residuales y pruebas de razón de verosimilitud a ...

Typhoon effects on litterfall in a subtropical forest

Canadian Journal of Forest Research, 2003
The litterfall in a subtropical broadleaf forest within the Fushan Experimental Forest in northeastern Taiwan was monitored for 9 years. Mean annual litterfall was very sensitive to typhoon frequency and intensity, ranging from 3 to 11 Mg·ha–1·year–1. Litterfall was significantly higher in years with strong typhoons than in years without typhoons, and

Multiple nutrients limit litterfall and decomposition in a tropical forest

Ecology Letters, 2007
AbstractTo explore the importance of 12 elements in litter production and decomposition, we fertilized 36 1600 m2‐plots with combinations of N, P, K, or micronutrients (i.e. B, Ca, Cu, Fe, Mg, Mn, Mo, S, Zn) for 6 years in a lowland Panamanian forest. The 90% of litter falling as leaves and twigs failed to increase with fertilization, but reproductive ...

The Importance of Leaching from Litter Collected in Litterfall Traps

Environmental Monitoring and Assessment, 2001
Litterfall (LF) is usually collected by means of open traps. However, this litter will be subject to leaching by the throughfall which passes through the accumulated litter in the traps. The nutrients lost during this leaching are not taken into account in the calculation of LF nutrient fluxes.

Movement of Radiocesium as Litterfall in Deciduous Forest

2019
Litterfall is an important agent in the process of radiocesium movement in forest ecosystems; however, the information is limited. We clarified the process of radiocesium movement in Konara oak forest and predicted the timing of resume of leaf litter for leaf litter origin compost production as management implications.
