Seedling mortality from litterfall increases with decreasing latitude
Ecology, 2015AbstractGlobal patterns in ecology need to be identified and interpreted if macroecological processes are to be fully understood. Facilitating effects on seedlings such as that of nurse plants and competitive effects such as allelopathy have been well recognized but the importance of plants acting as killers through physical damage by the litterfall ...

Mixed models applied to the litterfall productivity
2014Se 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 ...

Litterfall from two eucalypt woodlands in central Queensland
Australian Journal of Ecology, 1999AbstractThe mean annual litterfall at two dry woodland sites in central Queensland was 1129 kg ha–1 for an open E. populnea F. Muell. woodland (n = 2 years), and 2318 kg ha–1 for a woodland dominated by E. cambageana Maiden (n = 1 year). Leaves formed the largest component of total litterfall, which varied seasonally with a spring–summer maximum ...

Litterfall dynamics and ecosystem recovery during forest development
Forest Ecology and Management, 1994Abstract A field study was conducted at the Hubbard Brook Experimental Forest (USA) to quantify changes in the mass, chemistry and timing of litterfall during stand development of the northern hardwood forest and to relate changes to other ecologically meaningful forest dynamics. Leaf fall on three contiguous watersheds, harvested 1, 15 and 66 years

Factors Controlling Litterfall Production of Forest in China
Advanced Materials Research, 2013Litterfall production was shown to have a significant linear relationship with NPP in both natural and planted forests (R2= 0.67, 0.30,P<0.001). Correlation of litterfall production and climatic factors was higher in natural forest than in planted forest.

Seasonal patterns of litterfall in forest ecosystem worldwide
Ecological Complexity, 2014Abstract The seasonal litterfall plays an important role in the process of forest carbon and nutrient cycles. The current dynamic vegetation models use a simplified method to simulate seasonal patterns of litterfall, and assume that litterfall inputs distributed evenly through the year for deciduous trees or occur once during the start of year for ...

Litterfall in beech (Fagus sylvatica L.) forests.
2023This study is a part from a project "Structure and ecological functions of dead biomass in beech forests (Fagus sylvatica L.) in Western Bulgaria". The dead plant biomass plays an important role in the functioning and productivity of forest ecosystems through its influence on biodiversity, carbon dioxide storage, substance and energy cycling, soil ...

Sugar maple seed production and nitrogen in litterfall
Canadian Journal of Forest Research, 1991The influence of seed production on litterfall was studied for 2 years at five northern hardwood sites located across the Great Lakes region. Flower and seed litter contributed > 1 Mg•ha−1 dry matter in several instances, accounting for as much as 34% of total litter deposition.

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 ...

Litterfall mercury deposition in Atlantic forest ecosystem from SE – Brazil
Environmental Pollution, 2012Litterfall is believed to be the major flux of Hg to soils in forested landscapes, yet much less is known about this input on tropical environment. The Hg litterfall flux was measured during one year in Atlantic Forest fragment, located within Rio de Janeiro urban perimeter, in the Southeastern region of Brazil.
