Webredundancy, in the context of ocean biogeochemistry, has previously been defined as the ‘ability of one microbial taxon to carry out a process [i.e. a function] at the same rate as another under the same environmental conditions’ (Allison & Martiny, 2008). In an oceanic context, ecological redundancy could similarly be defined as ‘ability WebThe redundancy principle in biology expresses the need of many copies of the same entity (cells, molecules, ions) to fulfill a biological function.Examples are numerous: …
