Extinction Risk Escalates in the Tropics

open access: yesPLoS ONE, 2008
The latitudinal biodiversity gradient remains one of the most widely recognized yet puzzling patterns in nature. Presently, the high level of extinction of tropical species, referred to as the "tropical biodiversity crisis", has the potential to erode this pattern.

Generation lengths of the world's birds and their implications for extinction risk

open access: yesConservation Biology, 2020

Environmental and socioeconomic correlates of extinction risk in endemic species

open access: yesDiversity and Distributions: A journal of biological invasions and biodiversity, 2021
Our current understanding of the causes of global extinction risk is mostly informed by the expert knowledge‐based “threats classification scheme” of the IUCN Red List of Threatened Species.

Hurst Coefficient in long time series of population size: Model for two plant populations with different reproductive strategies [PDF]

open access: yes, 2010
Can the fractal dimension of fluctuations in population size be used to estimate extinction risk? The problem with estimating this fractal dimension is that the lengths of the time series are usually too short for conclusive results.

How predictable are mass extinction events?

open access: yesRoyal 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]

open access: yesThe 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.

Ecological correlates of extinction risk in Chinese terrestrial mammals

open access: yesDiversity and Distributions: A journal of biological invasions and biodiversity, 2021
China is among the countries with highest mammal diversity in the world, but a considerable proportion of Chinese terrestrial mammal species is currently at risk of extinction.

Digging the pupfish out of its hole: risk analyses to guide harvest of Devils Hole pupfish for captive breeding. [PDF]

open access: yes, 2014
The Devils Hole pupfish is restricted to one wild population in a single aquifer-fed thermal pool in the Desert National Wildlife Refuge Complex. Since 1995 the pupfish has been in a nearly steady decline, where it was perched on the brink of extinction ...

Effects of evolutionary history and life form on extinction risk of Chinese flowering plants

open access: yesGlobal 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

open access: yesDiversity, 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.
