Comparative soil bacterial metabarcoding after aboveground vs. subsurface decomposition of Mus musculus. [PDF]

Sci Rep
Outdoor microcosms, metabarcoding with next-generation sequencing of the 16S rRNA bacterial gene, total body score (TBS) and physicochemical analyses were used to monitor Mus musculus decomposition aboveground (A) and in the subsurface (S), and compared ...

Priority effects and density promote coexistence between the facultative predator Chrysomya rufifacies and its competitor Calliphora stygia. [PDF]

Oecologia, 2022
Highly competitive ephemeral resources like carrion tend to support much greater diversity relative to longer-lived resources. The coexistence of diverse communities on short-lived carrion is a delicate balance, maintained by several processes including ...

The spatiotemporal distribution of human pathogens in ancient Eurasia. [PDF]

Nature
Infectious diseases have had devastating effects on human populations throughout history, but important questions about their origins and past dynamics remain1.

A Machine Learning Approach for Using the Postmortem Skin Microbiome to Estimate the Postmortem Interval. [PDF]

PLoS ONE, 2016
Research on the human microbiome, the microbiota that live in, on, and around the human person, has revolutionized our understanding of the complex interactions between microbial life and human health and disease.

Editorial: Life and Death: New Perspectives and Applications in Forensic Science

Frontiers in Ecology and Evolution, 2021
Abstract Nowadays there are numerous scientific strategies thathelping to clarify forensic cases, including time since death. The absence of reliable quantitative methods to estimate the post-mortem interval explains the increase in promising new lines of research for this purpose.

Warming and Reduced Rainfall Alter Fungal Necromass Decomposition Rates and Associated Microbial Community Composition and Functioning at a Temperate-Boreal Forest Ecotone. [PDF]

Glob Chang Biol
In this study we explored how warming temperature and low water availability influenced the decomposition of dead fungal biomass. We found that warming and low water availability sped up how much the dead fungal biomass was decomposed in the first 2 weeks it was put in the field.

Secondary Decomposers Meet Their Predators: Decomposition Stage and Substrate Quality Jointly Structure Microbial Brown Food Webs During Fungal Necromass Decay. [PDF]

Mol Ecol
ABSTRACT Mycelial residues, also known as fungal necromass, represent a substantial fraction of soil organic matter (SOM) pools in terrestrial ecosystems worldwide. Although microbial decomposers are increasingly recognised as key drivers of fungal necromass carbon stock formation, the diversity and composition of their microbial predators—and the ...

The Necrobiome of Deadwood: The Life after Death

Ecologies, 2022
In recent decades, sustainable forest management has been increasingly recognized, promoting the diffusion of silvicultural practices aimed at considering all components of the forest system. Deadwood is an important component of the forest ecosystem. It

Necromass of Diverse Root-Associated Fungi Suppresses Decomposition of Native Soil Carbon via Impacts of Their Traits. [PDF]

Ecol Lett
We investigated the decomposition of diverse root‐associated fungi, their influence on native soil carbon (C) dynamics and the relationship of these processes with fungal traits. Fungal melanin, blackness, C/N and growth rates were linked to necromass decomposability and its stabilisation. Necromass addition commonly caused suppression of native soil C

Fungi rather than bacteria drive early mass loss from fungal necromass regardless of particle size. [PDF]

Environ Microbiol Rep
Dead fungal mycelium (also known as necromass) had higher mass loss, respiration, pH, and water content when colonized by fungi than by bacteria. When co‐cultured with a fungus, bacterial strains grew significantly more on necromass as the C source than when growing alone, while fungal growth was not significantly affected by bacteria.
