Extinctions? What extinctions?
New Scientist, 2021There are a growing number of people who deny the threats that many species face.

BioEssays, 2000
In the life of any species, extinction is the final evolutionary process. It is a common one at present, as the world is entering a major extinction crisis. The pattern of extinction and threat is very non-random, with some taxa being more vulnerable than others.

Resistance to extinction versus extinction as discrimination
Journal of the Experimental Analysis of Behavior, 2021The hypothesis that response strength might be measured by persistence of responding in the face of extinction was discredited in the 1960s because experiments showed that responding persists longer following intermittent reinforcers than following continuous reinforcers.

Cretaceous Dinosaur Extinction
Evolution, 1968The reign of dinosaurs, dominant on land for about 150 million years, terminated at the close of the Cretaceous. They did not all disappear at precisely the same moment, but from a peak of about 120 genera near the middle of the period, dwindled in numbers down to the end of Cretaceous at which time a large number of genera became extinct (Newell, 1962;

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 ...

Lists of extinct species often act as “wake-up calls” and are based on the length of time since the last sighting, resulting in numerous species having been prematurely classified as being extinct only to be rediscovered ([1][1]). This not only provides ammunition for environmental sceptics (D.
