Scavengers and decomposers
also clear refuse from the seafloor.
That lack of salt keeps decomposer
numbers in check, while plants, which don't need salt, flourish, piling up carbon on the forest floor when they die.
The new assay, however, may change that by making it possible for scientists to quickly screen the genes in masses of anonymous microbes taken from the forest floor, compost heaps, or other outdoor places where decomposers
live and work.
One is simply that invasives are more palatable to decomposers
due to potentially low C:N ratios, as observed in this study, and low lignin (or other recalcitrant components) in their leaves.
Nutrients in the organic matter, including carbon, are released into the soil with the help of decomposers
such as fungi and bacteria.
These beetles are late-stage decomposers
, meaning they do not eat fresh meat.
The search for excellent enzymes has taken chemist Charles Lee, and co-workers with the Albany center's Bioproduct Chemistry and Engineering Research Unit, to outdoor places where decomposers
live and work.
But without multiple species of crops and animals, the farms lacked natural predators, fertilizers and decomposers
, which healthy ecosystems require.
The nickel pellets used are a bulk sample ("run of mill") taken from the decomposers
at Inco's nickel refinery at Copper Cliff, Ontario.
However, the technique has been criticised on the grounds that the mesh could hinder entry of soil animals (earthworms and arthropods), which may be important decomposers
in some systems.
Students will explore the relationship of the earth to the sun, the important role of leaves and decomposers
and how animals respond to the imminent arrival of winter.
In most forests, the old growth is dominated by decomposers
in terms of species number and complexity," he says.
