Mapping the forest litterfall mercury deposition in China

Science of the Total Environment, 2022
Litterfall mercury (Hg) deposition represents one of the biggest Hg inputs to forest ecosystems through assimilation of atmospheric gaseous elemental Hg (Hg0) to foliage. However, due to the availability of litterfall production and Hg concentration data, a comprehensive quantification of litterfall Hg deposition is still lacking in China.

Assessment of Global Mercury Deposition through Litterfall

open access: yesEnvironmental Science & Technology, 2016
There is a large uncertainty in the estimate of global dry deposition of atmospheric mercury (Hg). Hg deposition through litterfall represents an important input to terrestrial forest ecosystems via cumulative uptake of atmospheric Hg (most Hg(0)) to foliage.

Litterfall mercury dry deposition in the eastern USA

Environmental Pollution, 2012
Mercury (Hg) in autumn litterfall from predominately deciduous forests was measured in 3 years of samples from 23 Mercury Deposition Network sites in 15 states across the eastern USA. Annual litterfall Hg dry deposition was significantly higher (median 12.3 micrograms per square meter (μg/m(2)), range 3.5-23.4 μg/m(2)) than annual Hg wet deposition ...

Seasonal patterns of litterfall in forest ecosystem worldwide

Ecological Complexity, 2014
Abstract 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 ...

Fine litterfall in the Brazilian Atlantic Forest

Biotropica, 2017
AbstractLitterfall is an essential component of tropical forest productivity, transferring nutrients from the vegetation back to soils. Here, we summarize the data from 105 estimates of fine litterfall production from 45 sites in the Atlantic Forest domain, including two types of forests, evergreen and seasonal, and two successional stages, secondary ...

Quantifying the interannual litterfall variations in China’s forest ecosystems

open access: yesJournal of Plant Ecology, 2020
Aims Litterfall is a key parameter in forest biogeochemical cycle and fire risk prediction. However, considerable uncertainty remains regarding the litterfall variations with forest ages.

The influence of macro‐litterfall and forest structure on litterfall damage to seedlings

Austral Ecology, 2004
Abstract  Microdisturbance to seedlings is important because it can differentially affect the mortality and recruitment of seedlings of forest tree species and thereby ultimately affect community composition. Microdisturbance due to litterfall has been shown to vary greatly in its influence on seedling survival among and within forests, and yet there ...

Forest Litterfall in Mount Kasunogan

SMCC Higher Education Research Journal, 2020
Forest litterfall is plant materials that have been fallen to the ground. It is vital in the process of nutrient forests. The vegetation of the stations in Mount Kasunogan consisted of 7 plant species from 7 different families; Tamanu (Calophyllum) from Calophyllaceae, Sweet flag (Calamus Sp) from Acoraceae, Pitanga (Eugenia Sp) from Myrtaceae, Cogon ...
