The term guild is a broad term to describe the relationship between different species using the same resource. Since it is difficult to classify a guild it can be broken down into two more specific categories, alpha guilds and beta guilds. Alpha guild is specifically related to species that share a resource used within the same community. [10]
Mutualism in microbial ecology is a relationship between microbial species and humans that allows for both sides to benefit. [31] One such example would be syntrophy, also known as cross-feeding, [30] of which 'Methanobacterium omelianskii ' is a classical example. [32] [33] This consortium is formed by an ethanol fermenting organism and a ...
A microbiome (from Ancient Greek μικρός (mikrós) 'small' and βίος (bíos) 'life') is the community of microorganisms that can usually be found living together in any given habitat. It was defined more precisely in 1988 by Whipps et al. as "a characteristic microbial community occupying a reasonably well-defined habitat which has ...
Functional group (ecology) A functional group is merely a set of species, or collection of organisms, that share alike characteristics within a community. Ideally, the lifeforms would perform equivalent tasks based on domain forces, rather than a common ancestor or evolutionary relationship. This could potentially lead to analogous structures ...
Functional ecology. Bees serve the ecological function of pollinating flowers, maintaining flora reproduction and density in the ecosystem. Functional ecology is a branch of ecology that focuses on the roles, or functions, that species play in the community or ecosystem in which they occur. In this approach, physiological, anatomical, and life ...
Gut microbiota, gut microbiome, or gut flora are the microorganisms, including bacteria, archaea, fungi, and viruses, that live in the digestive tracts of animals. [ 1 ][ 2 ] The gastrointestinal metagenome is the aggregate of all the genomes of the gut microbiota. [ 3 ][ 4 ] The gut is the main location of the human microbiome. [ 5 ]
Metagenomics allows researchers to access the functional and metabolic diversity of microbial communities, but it cannot show which of these processes are active. [59] The extraction and analysis of metagenomic mRNA (the metatranscriptome ) provides information on the regulation and expression profiles of complex communities.
e. A microorganism, or microbe, [ a ] is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.
