Litter Decomposition in the Desert

BioScience, 1981
havior 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.

Decomposition of bracken litter

Botanical Journal of the Linnean Society, 1976
Investigations on the decomposition of bracken petioles, over a five-year period on six adjacent soil types, including moder-type humus, mull and peat, are reviewed.

Litter decomposition and nutrient release from monospecific and mixed litters: Comparisons of litter quality, fauna and decomposition site effects

Journal of Ecology, 2022
Abstract Litter decomposition and nutrient release are key processes for soil C and nutrient cycling. However, the relative importance of the effects of litter quality, fauna and decomposition site on litter decomposition remains poorly understood.

Methods for Estimating Litter Decomposition

2008
Litterfall in terrestrial ecosystems represents the primary pathway for nutrient return to soil. Heterotrophic metabolism, facilitated through comminution by small insects and leaching during precipitation events, results in the release of plant litter carbon as CO2 into the atmosphere.

Litter decomposition rate is dependent on litter Mn concentrations

Biogeochemistry, 2006
A 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.

Measurement of Leaf Litter Decomposition

1999
Decomposition is a complex and multistep process of litter breakdown through leaching, mechanical and invertebrate fragmentation, and transformation through the activity of soil microorganisms (Swift et al. 1979). The rate of litter decomposition varies with chemical composition, abiotic factors and biotic factors (Singh and Gupta 1977).

EFFECTS OF DIMILIN® ON FRESHWATER LITTER DECOMPOSITION

Environmental Toxicology and Chemistry, 1988
Abstract The pesticide Dimilin® (diflubenzuron) is widely used on forests in Maryland to control gypsy moths, and it may enter streams via leaf litter. We measured the effects of Dimilin on stream leaf litter processing using artificial leaf packs treated with the pesticide.

Soil Respiration and Litter Decomposition

2003
Emissions of CO2 from the organic and mineral soil horizons into the atmosphere are considered a good representation of soil respiration (R soil) when the diffusion-driven losses to the atmosphere are at equilibrium with the biological rates of CO2 production (Hanson et al. 2000). R soil is the net effect of the biological activity of autotrophic roots

Litter Decomposition in Forest Soils

1992
Litter decomposition was studied in seven Bavarian forest soils with mull, moder, and mor humus types by means of solid-state 13C nuclear magnetic resonance (NMR) spectroscopy and individual compound class analyses. Results show that litter decomposition involves oxidative polysaccharide and lignin biodegradation and a concomitant enrichment of non ...
