Abstract

The concept of the extinction debt has 2 components : a direct timelag between an environmental perturbation and the consequent extinction of a species and the idea that among species going extinct the strong competitors/weak colonizers go extinct first. Although the term was first used in 1994 in the context of metapopulation models, its roots go back to general systems theory and the theory of island biogeography. The strongest critiques of the concept emphasize that the direct trade-off between competition and colonization abilities is not simple. The original application was to remnant habitat patches, but it could be applied to spatially heterogeneous habitats that are subject to climate change or invasive species
