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.
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 1999, Brian Walker received the Ecological Society of Australia's Gold Medal for his work on ecology of tropical savannahs and rangelands. [2]In 2018, Brian Walker has been awarded the Blue Planet Prize for 2018, along with Professor Malin Falkenmark. [3]
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 history ...
Though Ulanowicz began his career modeling ecological systems using differential equations, he soon reached the limits of this approach. [4] Realizing that any ecosystem is a complex system , he decided to move away from what he saw as the inappropriate use of the reductionist approach, and instead began to work towards development of ...

The time for the fastest particles to reach a target in the context of redundancy depends on the numbers and the local geometry of the target. In most of the time, it is the rate of activation. This rate should be used instead of the classical Smoluchowski's rate describing the mean arrival time, but not the fastest. The statistics of the ...
Vulnerability is an attribute typical to the vessel and therefore heavily affected by the vessel's basic characteristics such as size, subdivision, armouring, and other hardening features, and also the design of the ship's systems, in particular the location of equipment, degrees of redundancy and separation, and the presence within a system of ...
