These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.  |  In general, it has been suggested that greater biodiversity confers more stability to ecosystems. As a result, less oxygen enters the lake's water. With greater biodiversity, the loss of one type of organism could be moderated by the adaptation of other organisms to fill its role. But until now, it’s been unclear how biodiversity losses stack up against other human-caused environmental changes that affect ecosystem health and productivity. A keystone species: Influences the survival of many other species in the ecosystem. Impacts of biodiversity change on ecosystem stability There is concern about the potential effect of biodiversity loss on the functioning of ecosystems and their services to society. warming; biodiversity; ecosystem function; traits; microbial ecology; The impact of biodiversity loss on the productivity and stability of ecosystems is a major concern (1, 2).Substantial evidence exists across diverse biomes that ecosystems with higher levels of biodiversity are also more productive and stable (3, 4).Biodiversity loss driven by factors such … 0. Nat Microbiol. Increased alpha diversity (the number of species present) generally leads to greater stability , meaning an ecosystem that has a greater number of species is more likely to withstand a disturbance than an ecosystem of the same size with a lower number of species. Epub 2012 Dec 6. However, associating biodiversity loss with species loss alone overlooks other subtle phenomena that threaten long-term ecosystem health. How does the biodiversity of an ecosystem affect its ability to withstand environmental stress? High biodiversity decreases the chances that an ecosystem will encounter an extreme disturbance. Biodiversity, the rich variety of living things that have evolved over millions of years to live in particular habitats, contributes to the beauty of natural ecosystems as well as to their resilience and stability. Why is India called a mega biodiversity center? Here we studied communities of aquatic ciliates to understand how temporal variability, resistance and overall ecosystem stability responded to diversity (that is, species richness) in a large experiment involving 690 micro-ecosystems sampled 19 times over 40 days, resulting in 12,939 samplings.

Previous biodiversity manipulation studies rarely reported such negative covariation despite general predictions of the negative effects of diversity on individual stability components3. In order to understand the effects that changes in biodiversity will have on ecosystem functioning, it is important to define some terms. Concern that the rapid anthropogenic erosion of biodiversity may undermine the delivery of ecosystem services has prompted a synthesis of community and ecosystem ecology over the last decade. Observed that higher diversity led to higher productivity, reduced invasions, lower severity of disease or pest outbreaks -observations from simple ag systems, disturbed urban areas, and islands. Biodiversity changes affect ecosystem functioning and significant disruptions of ecosystems can result in life sustaining ecosystem goods and services. The effects of diversity on ecosystem multifunctionality would also be hump- or U-shaped if diversity had positive effects on some functions and negative effects on others. Ecosystems. (2) How does biodiversity contribute to the stability and maintenance of ecosystem processes in the face of perturbations (long‐term effects of biodiversity)? Some ideas- stability refers to the ability to withstand a disturbance without changing, recover species diversity following a disturbance, and/or maintain productivity or function as conditions may change over time. “Some people have assumed that biodiversity effects are relatively minor compared to other environmental stressors,” said biologist David Hooper of Western Washington University, the lead author of the Nature paper. how does diversity affect ecosystem stability? doi: 10.7554/eLife.58999. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply.
