Extinction Debt at Extinction Threshold
Conservation Biology, 2002Abstract: To allow for long‐term metapopulation persistence, a network of habitat fragments must satisfy a certain condition in terms of number, size, and spatial configuration of the fragments. The influence of landscape structure on the threshold condition can be measured by a quantity called metapopulation ...

The author discusses extinctions that could occur in the 100 years following 2013, focusing on the impact of invasive species, diseases, and climate change on animal populations and providing recommendations that could avert extinctions. According to the author, coral reefs may disappear, poaching could result in the extinction of the Borneo rhino, and

Human Nature, 1994
The probability of lineal extinction is sensitive to all the moments of the reproductive success probability distribution. In particular, high variance in reproductive success is associated with high probability of lineal extinction. Where male variance in reproductive success exceeds female variance, strictly patrilineal lines of descent will become ...

The pharmacology of extinction
Journal of Ethnopharmacology, 1992It is impossible to predict what compounds of pharmacological interest may be present in an unexamined species. The extinction of such species may result, therefore, in the loss of therapeutically significant compounds. The fact that science will never know what has been lost does not lessen the significance of the loss.

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1989
Abstract A species may go extinct either because it is unable to evolve rapidly enough to meet changing circumstances, or because its niche disappears and no capacity for rapid evolution could have saved it. Although recent extinctions can usually be interpreted as resulting from niche disappearance, the taxonomic distribution of ...

Foundations of Science, 1995
It is widely believed that empiricism, though once dominant, is now extinct. This turns out to be mistaken because of incorrect assumption about the initial dominance of logical empiricism and about the content and variety of logical empiricist views.
