The Residence Time Of Litter On The Forest Floor Increases

Our estimate of the q 10 temperature coefficient for leaf litter decomposition was 2 17 within the commonly reported range for heterotrophic organic matter decomposition 1 5 2 5 across a broad range of ecosystems.

The residence time of litter on the forest floor increases.

The forest floor is a major reservoir of organic matter and nutrients for the ecosystem and as such it influences or regulates most of the functional processes occurring throughout the ecosystem. Litter mass loss or decay is the sum of carbon dioxide co 2 release and discharge of compounds. 1 two stands within this age class that were treated with nonlethal understorey fires in 1962 and 1963 stand nos. The size of the compartments was similar.

Leaf litter decomposition rates were a positive linear function of mat causing the residence time of leaf litter on the forest floor to decline by 31 days for each 1 c increase in mat. Leaf tissue can account for more than 70 of above ground litter fall in forests and the rest is composed of stems small twigs and propagative structures robertson and paul 1999. The mean residence time of the forest floor is the standing stock divided by the annual litter inputs. Prediction of soil macroporosity based on litter input.

Leaf litter decomposition rates were a positive linear function of mat causing the residence time of leaf litter on the forest floor to decline by 31 days for each 1 c increase in mat. The residence time in each compartment t r i increased with depth from 1 10 0 35 years for compartment l to 2 59 1 86 years for compartment f2b. Our estimate of the q 10 temperature coefficient for leaf litter decomposition was 2 17 within the commonly reported range for heterotrophic organic matter decomposition 1 5 2 5 across a broad range of ecosystems. The time required for a 50 loss of dry weight half life of standing litter is calculated as ln 0 5 k slow.

The mean residence time of litter is calculated as 1 k slow. Residence time forest floor litter. A time period where the megaphona were dying off from human interactions and increase in population about 10 000 years ago. Leaf litter decomposition rates were a positive linear function of mat causing the residence time of leaf litter on the forest floor to decline by 31 days for each 1 c increase in mat.

2 and 3. Decomposition litter fall and nutrient and organic matter turnover rates were determined in five eastern ontario jack pine pinusbanksiana lamb stands having various burning histories including wildfire the stands included a 65 year old age class stand no. Litter fall in terrestrial ecosystems signifies a crucial pathway for nutrient return to the soil. This study reports on the nutrient and organic matter content of the forest floor of the hubbard brook experimental forest during different seasons and attempts to correlate results from studies of.
