How predictable are mass extinction events?
Royal Society Open Science, 2023 Many modern extinction drivers are shared with past mass extinction events, such as rapid climate warming, habitat loss, pollution and invasive species.

Can Life History Predict the Effect of Demographic Stochasticity on Extinction Risk? [PDF]
The American Naturalist. 2012. 179(6): 706-720, 2013 Demographic stochasticity is important in determining extinction risks of small populations, but it is largely unknown how its effect depends on the life histories of species. We modeled effects of demographic stochasticity on extinction risk in a broad range of generalized life histories, using matrix models and branching processes.

Effects of evolutionary history and life form on extinction risk of Chinese flowering plants
Global Ecology and Conservation, 2023 There has been much debate on what, including evolutionary history, ecological processes or environmental change, might contribute to species extinctions.

Ecological and Conservation Correlates of Rarity in New World Pitvipers
Diversity, 2019 Rare species tend to be especially sensitive to habitat disturbance, making them important conservation targets. Thus, rarity patterns might be an important guide to conservation efforts.

Conservation Letters, 2020 The International Union for Conservation of Nature's (IUCN) Red List is the global standard for quantifying extinction risk but assessing population reduction (criterion A) of wide‐ranging, long‐lived marine taxa remains difficult and controversial.

Extinction risk of a Metapopulation under the Allee Effect [PDF]
Phys. Rev. E 101, 012135 (2020), 2019 We study the extinction risk of a fragmented population residing on a network of patches coupled by migration, where the local patch dynamics include the Allee effect. We show that mixing between patches dramatically influences the population's viability. Slow migration is shown to always increase the population's global extinction risk compared to the

Extinction risk from climate change [PDF]
Nature, 2004 Climate change over the past approximately 30 years has produced numerous shifts in the distributions and abundances of species and has been implicated in one species-level extinction. Using projections of species' distributions for future climate scenarios, we assess extinction risks for sample regions that cover some 20% of the Earth's terrestrial ...

Accelerated mass extinction in an isolated biota during Late Devonian climate changes
Scientific Reports, 2021 The fossil record can illuminate factors that contribute to extinction risk during times of global environmental disturbance; for example, inferred thermal tolerance was an important predictor of extinction during several mass extinctions that ...

Area‐based assessment of extinction risk [PDF]
Ecology, 2012 Underpinning the International Union for Conservation of Nature (IUCN) Red List is the assessment of extinction risk as determined by the size and degree of loss of populations. The IUCN system lists a species as Critically Endangered, Endangered, or Vulnerable if its population size declines 80%, 50%, or 30% within a given time frame.

Frontiers in Ecology and Evolution, 2022 China has many threatened plant species, which are exposed to environmental degradation and other anthropogenic pressures. We assessed support for potential extinction pathways in Chinese angiosperm genera and quantified possible threats to phylogenetic ...
