Evolution of the Earth Microbial Co-occurrence Network [PDF]

, 2021
Abstract Background: Co-occurrence pattern provides vital insight into complex microbial interactions of microbiomes. Although network analysis offers useful tools for describing microbial co-occurrence pattern, evolution of co-occurrence networks remains largely uncharacterized.

Exploring frailty and its domains – Systematic mapping of the literature

Indian Journal of Public Health, 2023
Background: 'Frailty' has no consensual definition till date, although the term occupies a pivotal role in geriatric medicine. A bibliometric analysis of the literature serves to capture the keyword cooccurrences and linkages, co-citations, author ...

Visualising text co-occurrence networks [PDF]

, 2016
We present a tool for automatically generating a visual summary of unstructured text data retrieved from documents, web sites or social media feeds. Unlike tools such as word clouds, we are able to visualise structures and topic relationships occurring in a document. These relationships are determined by a unique approach to co-occurrence analysis. The

Vertically Exported Phytoplankton (< 20 µm) and Their Correlation Network With Bacterioplankton Along a Deep-Sea Seamount

Frontiers in Marine Science, 2022
Phytoplankton have been observed to be widely distributed in the oceanic vertical water columns and have an important contribution to carbon sequestration via biological pump mechanism. However, in seamount areas with strong hydrodynamics, their vertical

A Bayesian derived network of breast pathology co-occurrence

Journal of Biomedical Informatics, 2008
In this paper, we present the validation and verification of a machine-learning based Bayesian network of breast pathology co-occurrence. The present/not present occurrences of 29 common breast pathologies from 1631 pathology reports were used to build the network. All pathology reports were developed by a single pathologist.

Exploring the random genesis of co-occurrence networks [PDF]

Physica A: Statistical Mechanics and its Applications, 2011
Using the network random generation models from (Gustedt 2009), we simulate and analyze several characteristics (such as the number of components, the degree sequence and the clustering coefficient) of the generated networks. This is done for a variety of distributions (fixed value, Bernoulli, Poisson, binomial) that are used to control the parameters ...

Effects of Different Heavy Metal Stressors on the Endophytic Community Composition and Diversity of Symphytum officinale

Microorganisms
Endophytes play an important role in helping plants resist heavy metal stress. However, little is known about the effects of different heavy metals on the diversity and composition of endophyte communities.

Unbalanced diets enhance the complexity of gut microbial network but destabilize its stability and resistance

Stress Biology, 2023
Stability is a fundamental ecological property of the gut microbiota and is associated with host health. Numerous studies have shown that unbalanced dietary components disturb the gut microbial composition and thereby contribute to the onset and ...

Effects of environmental and biological characteristics on leaf decomposition under wetland restoration conditions

Global Ecology and Conservation
The implementation of ecological restoration projects, such as wetland rehabilitation, is essential for achieving sustainable development. However, current research on monitoring recovery status primarily focuses on evaluating water quality and aquatic ...

Using co‐occurrence network topology in assessing ecological stress in benthic macroinvertebrate communities

Ecology and Evolution, 2019
Ecological monitoring of streams has often focused on assessing the biotic integrity of individual benthic macroinvertebrate (BMI) communities through local measures of diversity, such as taxonomic or functional richness.
