A dead mammal (i.e. cadaver) is a high quality resource (narrow carbon:nitrogen ratio, high water content) that releases an intense, localised pulse of carbon and nutrients into the soil upon decomposition. Despite the fact that as much as 5,000 kg of cadaver can be introduced to a square kilometre of terrestrial ecosystem each year, cadaver decomposition remains a neglected microsere. Here we review the processes associated with the introduction of cadaver-derived carbon and nutrients into… 

Temporal and Spatial Impact of Human Cadaver Decomposition on Soil Bacterial and Arthropod Community Structure and Function

TLDR
There is strong evidence of a predictable response to cadaver decomposition that varies over space for soil bacterial and arthropod community structure, carbon (C) mineralization and microbial substrate utilization patterns, which can be applicable to environmental bio-monitoring and forensic sciences.

The impact of the decomposition process of shallow graves on soil mite abundance

TLDR
It is found that the decay of three pig cadavers buried in shallow graves caused a significant increase in the soil pH throughout decomposition, from neutral to alkaline, which affected the abundance and diversity of the associated mites.

Soil Fauna and Their Effects on Decomposition Within Coniferous and Deciduous Tree Soil Samples

Soils are dynamic environments that undergo constant change due to activities of the community that lives within and upon them. This dynamic system as a medium for corpse decomposition is little

Carrion decomposition and nutrient cycling in a semiarid shrub–steppe ecosystem

Vertebrate carrion decomposition and nutrient cycling have both direct and indirect effects on the soil properties, fauna, and flora associated with an animal's carcass. While few comprehensive

Functional and Structural Succession of Soil Microbial Communities below Decomposing Human Cadavers

TLDR
The results revealed the pattern of functional and compositional succession in soil microbial communities during decomposition of human-derived organic matter, provided insight into decomposition processes, and identified putative predictor populations for time since death estimation.

Spatial impacts of a multi-individual grave on microbial and microfaunal communities and soil biogeochemistry

TLDR
It is demonstrated that human decomposition influences soil biogeochemistry, microbes, and microfauna up to four years after burial.

Elemental analysis of soil and vegetation surrounding decomposing human analogues

ABSTRACT The introduction of cadaveric material creates a localized surge of nutrients into the surrounding environment, which can have a profound effect on soil and vegetation in contact with the

Forensic taphonomy: processes associated with cadaver decomposition in soil

A series of laboratory and field incubations were carried out where juvenile rat (Rattus rattus) cadavers were buried in three soils of contrasting texture from tropical savanna ecosystems in

Biodiversity and ecosystem function in soil

TLDR
The combination of taxonomic diversity and rapid carbon flux makes the soil ecosystem highly resistant to perturbation through either changing soil structure or removing selected groups of organisms.

Nitrogen effects on conservation of carbon during corn residue decomposition in soil

Nitrogen fertilization is widely recognized for its potential to help maintain soil organic matter (SOM) concentrations by increasing plant growth and amounts of plant material decomposed in soils.

Plant community composition affects the biomass, activity and diversity of microorganisms in limestone grassland soil

TLDR
It is hypothesized that the discriminating functional attribute leading to a reduction of bacterial diversity in these microcosms was the presence in the F. ovina and mixed-plant communities of an active arbuscular–mycorrhizal mycelium that is absent from bare soil and monocultures of C. flacca.

Prairie vegetation and soil nutrient responses to ungulate carcasses

TLDR
By providing a niche for species not normally found in undisturbed prairie, carcasses increased community heterogeneity and may play an important role in adding spatial complexity to grassland ecosytems.

The Soil Biomass

TLDR
The biomass will be considered as an undifferentiated whole, usually expressed quantitatively as biomass-C.

Decomposition of elephant dung in an arid, tropical environment

TLDR
Under high moisture controlled conditions CO2 evolution from the dung was primarily temperature limited, but a decrease in the carbon mineralisation rate and the temperature response over the 14 day experimental period suggested that the availability of carbon and nutrient resources also became limiting to micro-organism activity.
