The phrase "abrupt extinction" is correct and usable in written English.
It can be used to describe a sudden and unexpected end to a species or a phenomenon.
Example: "The abrupt extinction of the passenger pigeon serves as a cautionary tale about the impact of human activity on wildlife."
Alternatives: "sudden extinction" or "rapid extinction".
This change could also have resulted in a major abrupt extinction that occurred in the area, the so called Vallesian crisis.
Further increase of the rotation velocity results in abrupt extinction of the entire diffusion flame-ring at a critical and constant value of the Rossby number Roc = 7.
Abrupt extinction was attributed to the quenching of the oxidation layer with the entire H OH O radical pool being comparably reduced.
"This abrupt extinction of marine life we can clearly see in the fossil record firmly links giant volcanic eruptions with global environmental catastrophe," Paul Wignall, a professor of paleontology at the University of Leeds and lead author on the study, said in a statement.
Early this decade, oceanographers and paleontologists found a striking coincidence recorded in 55-million-year-old deep-sea sediments: a 10,000-year-long warming of bottom waters, an equally abrupt mass extinction of tiny bottom-dwelling organisms called forams, and a shift in the relative abundance of carbon isotopes in the forams.
Many ecosystems across the globe have faced large-scale perturbations including massive extinctions, abrupt species shifts, and changing disturbance regimes as a result of human activities.
An abrupt increase in the extinction coefficient for higher photon energy is due to the fundamental bandgap absorption in the films.
For this, models have 'coupled population dynamics and evolution by natural selection to identify conditions for which evolution succeed – or fails – to rescue a closed population from extinction following abrupt environmental change' (Gomulkiewicz and Holt 1995).
In 2009 American geoarchaeologist Douglas Kennett of the University of Oregon at Eugene with seven coauthors from several universities published persuasive evidence linking a cosmic impact to megafaunal extinctions and abrupt ecosystem disruptions at the Younger Dryas boundary about 12,900 years ago, a time when Earth was emerging from the last glacial period.
But he also believes there is still time to avoid a crash in the variety of species more abrupt than any previous mass extinction.
The result we obtain helps in the understanding of the onset of abrupt transitions leading to the extinction of biological populations.
