years and designed to explore the role of biological diversity in maintaining the stability of coastal ecosystems. The experiments were designed to test theoretical predictions and mechanisms that explain the effects of biodiversity. So, at the first glance, the scope of this thesis might seem confined to the academic realm. A classic model for ecological stability revised, 40 years later Predator-prey relationships stabilize diverse ecosystems, according to calculation.

Ecosystems are the basis of life and all human activities. Conservation of biological diversity is very important for the proper functioning of the ecosystem and for delivering ecosystem services.

I suspect that diversity per se has little to do with the stability of most marine systems, i.e., the nondiverse systems are just as stable as those that are diverse. More to the point is whether characteristic diversity confers some predictability to by:

Although diversity-ecosystem theory predicts that ecosystem functioning is strongly determined by species number, species traits play an important role in regulating ecosystem-level : Na Zhao, Na Zhao, Xinqing Shao, Kun Wang.
Thus, beta diversity allows us to compare diversity between ecosystems. Gamma diversity is a measure of the overall diversity for the different ecosystems within a region. Hunter ( ) defines gamma diversity as "geographic-scale species diversity".

Biological diversity (biodiversity) helps to maintain healthy ecosystems, e.g., water quality, primary production, and decomposition. Biodiversity is therefore an important component of ecosystem services, which contribute to healthy, human livelihoods.
Increasing biodiversity results in increased ecosystem stability (Cardinale et al., ). Conversely, declines in biodiversity can have major implications for ecosystem.

Despite the theoretical nature of the idea, up until the s, ecologists agreed with what became known as the diversity-stability hypothesis: diverse ecosystems are more stable than ecosystems with fewer species.
Diversity of Ecosystems. Aim of this book is to bring out a general view on the function of ecosystems, modelling, sampling strategies, invading species, the response of organisms to modifications, the carbon dynamics, the mathematical models and theories that can be applied in diverse conditions.

INTRODUCTION. 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. Stability and diversity.
The relation between diversity and stability has been widely studied. Diversity can operate to enhance the stability of ecosystem functions at various ecological scales.
For example, genetic diversity can enhance resistance to environmental perturbations. Generally speaking, greater species diversity (alpha diversity) leads to greater ecosystem stability.
This is termed the "diversity–stability hypothesis." Warning: the simple answer is greater species diversity leads to increased stability, but this is not the complete answer.
The diversity-stability hypothesis states that ecosystems with greater species diversity are more stable.The positive slopes indicated that stability was an increasing function of vegetation diversity. Higher diversity ensured higher ecosystem stability so that lower proportional change of vegetation was caused by climate anomalies.
However, ecosystem stability was not correlated with Pielou evenness index (Fig. 6 d).Cited by: 6.Among terrestrial ecosystems, forests support the richest biological diversity. The interaction of humans and forests has a long history, but recent changes have been the most drastic ever.
The rapid decrease and deterioration of forest ecosystems has been caused by social, economic, and ecological factors, which may vary locally but are common.
