    concept of ecological diversity. Species diversity is the most commonly used representation of ecological diversity, but it is not the only measure. Niche width and habitat diversity are also key components of ecological diversity. Niche width describes the availability of resources to an organism (or taxon) over spatial and temporal scales. The first experiments to measure the relationship between diversity and stability manipulated diversity in aquatic microcosms — miniature experimental ecosystems — containing four or more trophic levels, including primary producers, primary and secondary consumers, and decomposers (McGrady-Steed et al. , Naeem & Li ).

McNAUGHTON Biological Research Laboratories, Syracuse University, College Place, Syracuse, New York , and Serengeti Research Institute, P.O. Seronera via Arusha, Tanzania. Does greater species diversity lead to greater stability in ecosystems? Viewpoint: Yes, greater species diversity does lead to greater stability in ecosystems. Viewpoint: No, ecosystem stability may provide a foundation upon which diversity can thrive, but increased species diversity does not confer ecosystem stability. In , Philip Handler, president of the United States National Academy.

    Abstract. Ecosystem stability in variable environments depends on the diversity of form and function of the constituent species. Species phenotypes and ecologies are the product of evolution, and the evolutionary history represented by co-occurring species has been shown to be an important predictor of ecosystem function. Aug 03,  · However, stability is not one, simple property of an ecosystem and there is no one, simple relationship between diversity and stability, say ecologists Tony Ives and Steve Carpenter of the.

Once the ecological stability to be assessed is defined, the next step could be to decide what facets of biological communities are focused. To date, numerous tools and metrics are currently available to evaluate the state of biological communities.

After much progress made with experimental studies in the 60's, Robert May advanced the field of theoretical ecology and refuted the idea that diversity begets stability. Many definitions of ecological stability have emerged in the last decades while the concept continues to gain attention. See also.

Attempts to unveil the relationships between the taxonomic diversity, productivity and stability of ecosystems continue to generate inconclusive, contradictory and controversial conclusions.

Reference Stability property Trophic. Oct 24,  · A major ecosystem effect of biodiversity is to stabilise assemblages that perform particular functions. However, diversity–stability relationships (DSRs) are analysed using a variety of different population and community properties, most of which are adopted from theory that makes several restrictive assumptions that are unlikely to be reflected in runrevlive.com by: Stability and Diversity of Ecosystems Anthony R.

Ives1 and Stephen R. Carpenter2 Understanding the relationship between diversity and stability requires a knowledge of how species interact with each other and how each is affected by the environment. The relationship is also. Ecological stability explained.

An ecosystem is said to possess ecological stability (or equilibrium) if it is capable of returning to its equilibrium state after a perturbation (a capacity known as resilience) or does not experience unexpected large changes in its characteristics across time.

In this paper we review the development of the diversity-stability hypothesis, evaluate attempts to support or refute it, and suggest an alternate perspective for interpreting population stability.

Jul 20,  · The diversity in interactions that occur between different species—such as predation, competition, and mutualism—is a fundamental feature of natural ecological systems. Using a theoretical model, Mougi and Kondoh (p.
