Insurance Hypothesis Ecology, Previous experimental investigations of the insurance hypothesis have not examined this mechanism. Here we examine this hypothesis theoretically. The spatial insurance hypothesis predicts that dispersal can mitigate the negative effect of environmental change on diversity by facilitating species sorting that is allowing the immigration of species that are adapted to the new environmental conditions loreau et al. Journal of animal ecology 2009 78 1 143 1 1 5 1 doi. This Insurance Hypothesis Ecology can keep free with high resolution 8k for your information and reference before execute your plan.
Yachi loreau 1999. Journal of animal ecology 2009 78 1 143 1 1 5 1 doi. Here we examine this hypothesis theoretically. Previous experimental investigations of the insurance hypothesis have not examined this mechanism.
Although the effect of biodiversity on ecosystem functioning has become a major focus in ecology its significance in a fluctuating environment is still poorly understood.
The insurance hypothesis predicts a stabilizing effect of increasing species richness on community and ecosystem properties. Insurance Hypothesis Ecology Difference among species responses to environmental fluctuations provides a general mechanism for the hypothesis. That is the correlation between pairs of species does not equal 1 0. A commonly used metric in ecology tilman et al 1998. The spatial insurance hypothesis predicts that dispersal can mitigate the negative effect of environmental change on diversity by facilitating species sorting that is allowing the immigration of species that are adapted to the new environmental conditions loreau et al. Petchey department of animal and plant sciences university of sheffield western bank sheffield s102tn uk summary 1. According to the biodiversity insurance hypothesis diverse ecosystems are more resilient to environmental change because assuming species specific responses to such changes they provide better guarantees that some species will maintain their performance even if others fail naeem li 1997. These models require that species do not fluctuate synchronously over time. Previous experimental investigations of the insurance hypothesis have not examined this mechanism. Pdf Biodiversity As Spatial Insurance The Effects Of Habitat Fragmentation And Dispersal On Ecosystem Functioning
The Spatial Insurance Hypothesis Connects Diversity To Ecosystem Download Scientific Diagram, The insurance hypothesis predicts a stabilizing effect of increasing species richness on community and ecosystem properties. A commonly used metric in ecology tilman et al 1998. By contrast with monocultures all of the individual plants are competing for the resources held within one specific ecological niche. One explanation of the relationship between biodiversity and ecosystem functioning lies in the spatial insurance hypothesis which centers on the idea that productivity and stability increase with biodiversity in a temporally varying. Previous experimental investigations of the insurance hypothesis have not examined this mechanism. Here we examine this hypothesis theoretically. The idea behind the insurance hypothesis is simple. Difference among species responses to environmental fluctuations provides a general mechanism for the hypothesis. When different species are present they are able to fulfil a variety of different ecological niches within a given ecosystem. According to the insurance hypothesis biodiversity insures ecosystems against declines in their functioning because many species provide greater guarantees that some will maintain functioning even if others fail.
