In ecology, functional equivalence (or functional redundancy) is the ecological phenomenon that multiple species representing a variety of taxonomic groups can share similar, if not identical, roles in ecosystem functionality (e.g., nitrogen fixers, algae scrapers, scavengers). [1] This phenomenon can apply to both plant and animal taxa.
Relatively high diversity levels are still observed despite the use of enrichment steps when working from environmental samples, [18] likely due to the high functional redundancy observed in environmental microbial communities, being a key asset of their functional stability.
The optimal paths for the fastest can be found using the Wencell-Freidlin functional in the Large-deviation theory. These paths correspond to the short-time asymptotics of the diffusion equation from a source to a target. In general, the exact solution is hard to find, especially for a space containing various distribution of obstacles.
Functional redundancy refers to the phenomenon that species in the same ecosystem fill similar roles, which results in a sort of "insurance" in the ecosystem. Redundant species can easily do the job of a similar species from the same functional niche. [13] This is possible because similar species have adapted to fill the same niche overtime.

In this case, the redundant part of the gene remains in the genome due to the proximity to the area that codes for the unique function. [17] The reason redundant genes remain in the genome is an ongoing question and gene redundancy is being studied by researchers everywhere. There are many hypotheses in addition to the backup and piggyback models.
Genetic redundancy is a term typically used to describe situations where a given biochemical function is redundantly encoded by two or more genes. In these cases, mutations (or defects) in one of these genes will have a smaller effect on the fitness of the organism than expected from the genes’ function.
Single-cell genomics is a powerful way to obtain microbial genome sequences without cultivation. This approach has been widely applied on marine, soil, subsurface, organismal, and other types of microbiomes in order to address a wide array of questions related to microbial ecology, evolution, public health and biotechnology potential.
