It is the resistance to change.

Diversity- the number and variety of species present in an area and their spatial distribution.

Alpha diversity- diversity within a particular area or ecosystem.

Beta diversity- the change in diversity between ecosystems.

Gamma diversity- the overall diversity in a landscape comprised of several ecosystems.
Rivet hypothesis

claims that each species added to an ecosystem increases ecosystem functions, although the increase in function may increase more slowly as more species are included.

Rivet popper hypothesis - Essay writers

Ecologists have argued for decades that species are not interchangeable. and presented convincing experimental evidence that this is true. Testing these three hypotheses, using small artificial microcosms in a controlled environmental facility called the “Ecotron,” they found that decomposition rates, water and nutrient retention varied idiosyncratically as species richness varied. However, the uptake of carbon and plant productivity declined with the numbers of species, as predicted by the rivet hypothesis.


The redundancy hypothesis predicts ..

Contrasting this theory is the “rivet hypothesis” ..

Contrasting this theory is the “rivet hypothesis” (), which suggests that all species make a contribution to ecosystem processes. Like the rivets on an airplane wing, redundancy is built in so that the wing doesn't fail. But as rivets fall out, the wing becomes impaired until it eventually fails and the plane — the entire system — crashes.


Ecological thresholds: a survey - ScienceDirect

The concept of ecological redundancy is sometimes referred to as and assumes that more than one species performs a given role within an ecosystem.More specifically, it is characterized by a particular speciesincreasing its efficiency at providing a service when conditions arestressed in order to maintain aggregate stability in the ecosystem.However, such increased dependence on a compensating species placesadditional stress on the ecosystem and often enhances itssusceptibility to subsequent . The redundancy hypothesis can be summarized as "species redundancy enhances ecosystem resilience".
