Microbial ecology of vertebrate decomposition in terrestrial ecosystems

open access: yesFEMS Microbiology Ecology, 2023
AbstractVertebrate decomposition results in an ephemeral disturbance of the surrounding environment. Microbial decomposers are recognized as key players in the breakdown of complex organic compounds, controlling carbon and nutrient fate in the ecosystem and potentially serving as indicators of time since death for forensic applications.

Direct relationship between evapotranspiration rate (ETO) and vertebrate decomposition rate

open access: yesForensic Science International, 2023
When vertebrate scavenging is excluded, the Evapotranspiration Rate (ETo) of a given geographic region directly regulates the decomposition rate of unclothed vertebrate carrion, with any deviation attributed to insect activity. We conducted four decomposition experiments using pig carrion (Sus scrofa domesticus) over the span of two years (2018-2020 ...

Effect of vertebrate exclusion on leaf litter decomposition in the coastal Atlantic forest of southeast Brazil

Tropical Ecology, 2021
Forest fragmentation is the main cause of biodiversity loss in the Anthropocene and it is triggering a top-down cascade effect that may influence leaf litter decomposition. However, the link between biodiversity loss and changes in ecosystem processes is not fully understood.

The role of ants in vertebrate carrion decomposition

Food Webs, 2019
Abstract We review the relevant literature on ant-carrion interactions, highlight what is known about ants in decomposition ecology, and present a framework for future studies that aim to quantify the direct and indirect effects of ants on decomposition. One hundred and fifty-four species of ants were documented on carrion.

Mortality hotspots: Nitrogen cycling in forest soils during vertebrate decomposition

Soil Biology and Biochemistry, 2018
Abstract Decomposing animals alter soil biogeochemical cycles, and these natural ephemeral nutrient patches (or ‘hotspots’) are important for maintaining landscape heterogeneity and enriching local biodiversity. Soil nitrogen (N) enrichment associated with decomposing animals has been documented, but to date an integrated systems-level understanding ...

The effect of clothing on decomposition and vertebrate scavengers in cooler months of the temperate southwestern Cape, South Africa [PDF]

open access: yesForensic Science International, 2020
With research providing conflicting results from different habitats across the globe, the effect of clothing on decomposition is unclear; some studies indicate clothing increases decomposition rate by facilitating increased insect activity, and others conclude clothing prolongs the decay process.

Total RNA Analysis of Bacterial Community Structural and Functional Shifts Throughout Vertebrate Decomposition [PDF]

open access: yesJournal of Forensic Sciences, 2019
AbstractMultiple methods have been proposed to provide accurate time since death estimations, and recently, the discovery of bacterial community turnover during decomposition has shown itself to have predictable patterns that may prove useful. In this study, we demonstrate the use of metatranscriptomics from the postmortem microbiome to simultaneously ...
