Biological and extrinsic correlates of extinction risk in Chinese lizards

Current Zoology, 2021
Abstract China is a country with one of the most species-rich reptile faunas in the world. However, nearly a quarter of Chinese lizard species assessed by the China Biodiversity Red List are threatened. Nevertheless, to date, no study has explicitly examined the pattern and processes of extinction and threat in Chinese lizards.

Testing the accuracy of biological attributes in predicting extinction risk

Perspectives in Ecology and Conservation, 2020
The assessment of species conservation status traditionally relies on population data. In the absence of such data, biological attributes have been applied to predict the degree of species’ vulnerability. Our study investigated the accuracy of biological

Contextual and Temporal Modulation of Extinction: Behavioral and Biological Mechanisms [PDF]

Biological Psychiatry, 2006
Extinction depends, at least partly, on new learning that is specific to the context in which it is learned. Several behavioral phenomena (renewal, reinstatement, spontaneous recovery, and rapid reacquisition) suggest the importance of context in extinction.

Exposure to Violence and Neglect Images Differentially Influences Fear Learning and Extinction

, 2020
The mechanisms by which exposure to adversity contributes to psychopathology development are poorly understood. Recent models link experiences of threat of harm and deprivation to psychopathology via disruptions in learning mechanisms underlying fear ...

Extinction debt on reservoir land-bridge islands [PDF]

, 2016
Large dams cause extensive inundation of habitats, with remaining terrestrial habitat confined to highly fragmented archipelagos of land-bridge islands comprised of former hilltops.

Behavioral Correlates of Primates Conservation Status: Intrinsic Vulnerability to Anthropogenic Threats. [PDF]

PLoS ONE, 2015
Behavioral traits are likely to influence species vulnerability to anthropogenic threats and in consequence, their risk of extinction. Several studies have addressed this question and have highlighted a correlation between reproductive strategies and ...

Biological Extinction and Climate Change [PDF]

, 2020
What are the current dimensions of biological diversity? Taxonomists have described approximately two million species of eukaryotic organisms. Many more remain unknown, and the global total may approximate 12 million species or more. Generally, for the past 65 million years, the rate of extinction of these species appears to have been ~0.1 extinctions ...

The predictability of extinction: biological and external correlates of decline in mammals [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2008
Extinction risk varies among species, and comparative analyses can help clarify the causes of this variation. Here we present a phylogenetic comparative analysis of species-level extinction risk across nearly the whole of the class Mammalia.

Utopia without us?

Esboços, 2021
As the prospect of self-authored human extinction increasingly appears as a plausible scenario of human futures, a growing number of efforts aim at comprehending it as the prospect of the world without us.
