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.

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.

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

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.

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

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 ...
