Plant residue decomposition and the nutrient release to the soil play a major role in global carbon and nutrient cycling. Although decomposition rates vary strongly with climate, nitrogen immobilization into litter and its release in mineral forms are mainly controlled by the initial chemical composition of the residues. We used a data set of approximately 2800 observations to show that these g...
An update in the progress of the scientific researches related to the functions of the soil organisms in the grassland ecosystem is shown. The performance of different microorganisms in this ecosystem is recognized, focusing, mainly, on the functions of primary decomposers, like beetles, worms and termites. It is emphasized that these organisms, responsible for decomposing the excretions of mam...
Vertebrate corpse decomposition provides an important stage in nutrient cycling in most terrestrial habitats, yet microbially mediated processes are poorly understood. Here we combine deep microbial community characterization, community-level metabolic reconstruction, and soil biogeochemical assessment to understand the principles governing microbial community assembly during decomposition of m...
The chemical complexity of decomposing plant litter is a central feature shaping the terrestrial carbon (C) cycle, but explanations of the origin of this complexity remain contentious. Here, we ask: How does litter chemistry change during decomposition, and what roles do decomposers play in these changes? During a long-term (730 days) litter decomposition experiment, we tracked concurrent chang...

We present a flexible method that rearranges the ranked output of compound splitters (i.e., decomposers of one-word compounds such as the German Kinderlied ‘children’s song’) using a distributional semantics model. In an experiment, we show that our re-ranker improves the quality of various compound splitters.
As ubiquitous decomposers, symbionts and parasites, fungi build populations not easily accommodated by population genetic theory. Identifying and delineating individuals and populations is often difficult, and recombination can occur in complex and variable ways. Genotyping and gene genealogies provide the framework for identifying and delineating individuals and for detecting recombination in ...
