The concept of species redundancy in ecosystem processes is troublesome because it appears to contradict the traditional emphasis in ecology on species singularity. When species richness is high, however, ecosystem processes seem clearly insensitive to considerable variation in biodiversity. Some elementary principles from reliability engineering, where engineered redundancy is a valued part of systems design, suggest that we should rethink our stance on species redundancy. For example, a…

The Importance of Ecological Redundancy for Ecosystems Restoration

Evidence that distinguishing redundant species and identifying key species is feasible for ecological restoration is provided and it is suggested that redundancy should also be part of the restoration monitoring, for example, by checking if functional groups have been recovered.

Biodiversity enhances ecosystem reliability

It is found that as the number of species per functional group increased, replicate communities were more consistent in biomass and density measures, suggesting that redundancy (in the sense of having multiple species perfunctional group) is a valuable commodity, and that the provision of adequate redundancy may be one reason for preserving biodiversity.

Does functional redundancy affect ecological stability and resilience? A review and meta‐analysis

. In light of rapid shifts in biodiversity associated with human impacts, there is an urgent need to understand how changing patterns in biodiversity impact ecosystem function. Functional redundancy

Measuring the functional redundancy of biological communities: a quantitative guide

The preservation of ecosystem processes under ongoing biotic erosion requires that some species within affected communities perform similar functions, a property that is usually defined as functional

Conservation implications of the link between biodiversity and ecosystem functioning

This work argues that the link between biodiversity and ecosystem functioning is an important additional argument for conservation for several reasons, and is moving to a scientific position based on accumulating experimental evidence.

Biological diversity and probability of local extinction of ecosystems

It is demonstrated that two principle components of biological diversity have antagonistic effects on the probability of ecosystem functioning, and an asymptotic relationship between number of functionally analogous species and probability of functioning is predicted, rather than a linear or complex one.

A quantitative measure of functional redundancy in microbial ecosystems

TCE functional redundancy is demonstrated to be closely and monotonically related to the resilience of a trait to extinctions of trait-bearing taxa and addresses shortfalls of other functional redundancy measurements by providing a generalizable, quantitative, and comparable functional redundancy measurement.

Rare Species and Ecosystem Functioning

It is suggested that until further research is conducted a prudent conservation approach is warranted wherein the contribution of less common species to ecosystem functioning is assumed.



Conserving Biological Diversity through Ecosystem Resilience

Ecological redundancy is good because it enhances ecosystem resilience, but functionally important groups that have only one or very few species deserve priority conservation attention because their functions could be quickly lost with species extinctions.

Biodiversity and Ecological Redundancy

This paper addresses the problem of which biota to choose to best satisfy the conservation goals for a particular region in the face of inadequate resources, and asserts that focusing on species is not the best approach.

Species redundancy: a redundant concept?

The concept of 'species redundancy' (or 'ecological redundancy') has recently been applied to community and conservation ecology. The suggestion is that, in some communities, some species are

The Theory of Diversity-Stability Relationships in Ecology

There is no simple relationship between diversity and stability in ecological systems, and an alternate perspective for interpreting population stability is suggested.

Biodiversity and stability in grasslands

ONE of the ecological tenets justifying conservation of biodiversity is that diversity begets stability. Impacts of biodiversity on population dynamics and ecosystem functioning have long been

Productivity and sustainability influenced by biodiversity in grassland ecosystems

THE functioning and sustainability of ecosystems may depend on their biological diversity1–8. Elton's9 hypothesis that more diverse ecosystems are more stable has received much

Empirical Evidence that Declining Species Diversity May Alter the Performance of Terrestrial Ecosystems

The results provide the first evidence (obtained by a direct manipulation of diversity under controlled environmental conditions) that ecosystem processes may be affected by loss of diversity.

It is shown that stability (as measured by return time to equilibrium) can increase with various measures of complexity, which include connectivity, interaction strength, and trophic efficiency.

Efforts to preserve biological diversity must focus increasingly at the ecosystem level because of the immense number of species, the majority of which are currently unknown. An ecosystem approach is

Biodiversity: Population Versus Ecosystem Stability

The relationships between biodiversity and stability were determined for both population and ecosystem traits in a long-term study of 207 grassland plots. Results demonstrate that biodiversity
