Decomposition of forest litters
Plant and Soil, 1959In 1878 Mul l e r of Denmark recognized two types of humus formation in forest soils and named these "mull" and "mor" 14 The mull type of humus has a loose, friable, crumbly structure; the organic matter is weil mixed with the mineral soil and plant residues can no longer be distinguished.

Litter Decomposition in the Desert
BioScience, 1981havior of these measures was calculated for small samples for all tables from 2 x 2 to 5 x 5; the resulting tables are presented and may be used in significance tests. Scientists who decide to use Colwell's measures should sample at least twice during the period of the most rapid fluctuation of interest.

Litter decomposition: a Russian matriochka doll
Biogeochemistry, 1990Litter is decomposed in a sequential process. In a concerted action animals and microorganisms break down complex organic matter to mineral products. Higher animals fragment and partially solubilize plant material. Subsequently, microorganisms (protozoa, fungi and bacteria) further degrade the organic matter to end products that cannot be metabolized ...

Litter decomposition, climate and liter quality
Trends in Ecology & Evolution, 1995Litter decomposition is controlled by three main factors: climate, litter quality and the nature and abundance of the decomposing organisms. Climate is the dominant factor in areas subjected to unfavourable weather conditions, whereas litter quality largely prevails as the regulator under favourable conditions.

2003
Leaf breakdown is considered a pivotal process in the metabolism of stream ecosystems (Webster et al., 1995; Wallace et al., 1997), providing important information on stream functioning (nutrient cycling and energy flow). Analyses of decomposing litter also inform us about the distribution and abundance (structure) of stream biota such as fungi ...

Models that Describe Litter Decomposition
2003The graphs for accumulated litter mass loss vs time form different patterns, which may be described using a few simple mathematical functions. Generally we may state that litter may decompose completely or leave a stabilized residue, which may decompose very slowly.

Litter-fall and litter decomposition in a low Mediterranean shrubland
Biology and Fertility of Soils, 2003Annual production of litter by Cistus incanus (L.) and Myrtus communis (L.) and decomposition dynamics of leaf litter of these species was studied in a Mediterranean shrubland. Myrtus and Cistus produced 472 and 429 g dry weight litter m-2 year-1, respectively. Leaves were the predominant litter component for both species. The average decay constant of

The effect of microarthropods on litter decomposition depends on litter quality
European Journal of Soil Biology, 2016Abstract Many studies have investigated whether microbiota has been adapted to decompose a given litter type but we have limited information about the specific role of microarthropods in litter decaying processes. This experiment studied functional redundancy of microarthropods in a litter decomposition system by interchanging mesofauna among three ...

Litter decomposition rate is dependent on litter Mn concentrations
Biogeochemistry, 2006A statistically significant linear relationship was found between annual mass loss of foliar litter in the late stages of decomposition and Mn concentration in the litter. We used existing decomposition data on needle and leaf decomposition of Scots pine (Pinus sylvestris L.), lodgepole pine (Pinus contorta var. contorta), Norway spruce (Picea abies (L.
