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

Biological Extinction and Climate Change [PDF]
Health of People, Health of Planet and Our Responsibility, 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 ...

Biological legacies buffer local species extinction after logging
Journal of Applied Ecology, 2013 SummaryClearcutting has been identified as a main threat to forest biodiversity. In the last few decades, alternatives to clearcutting have gained much interest. Living and dead trees are often retained after harvest to serve as structural legacies to mitigate negative effects of forestry.

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.

Biologically inspired near extinct system reconstruction [PDF]
13th IEEE International Conference on BioInformatics and BioEngineering, 2013 Recovery software system operations from a state of extensive damage without human intervention is a challenging problem as it may need to be based on a different infrastructure from the one that the system was originally designed for and deployed on (i.e., computational and communication devices) and significant reorganization of system ...

Vertebrates on the brink as indicators of biological annihilation and the sixth mass extinction
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance The ongoing sixth mass extinction may be the most serious environmental threat to the persistence of civilization, because it is irreversible.

The Sixth Mass Extinction: fact, fiction or speculation?
Biological Reviews of The Cambridge Philosophical Society, 2022 There have been five Mass Extinction events in the history of Earth's biodiversity, all caused by dramatic but natural phenomena. It has been claimed that the Sixth Mass Extinction may be underway, this time caused entirely by humans.

Cultural extinction in evolutionary perspective
Evolutionary Human Sciences, 2021 Cultural diversity is disappearing quickly. Whilst a phylogenetic approach makes explicit the continuous extinction of cultures, and the generation of new ones, cultural evolutionary changes such as the rise of agriculture or more recently colonisation ...

Extinction events can accelerate evolution. [PDF]
PLoS ONE, 2015 Extinction events impact the trajectory of biological evolution significantly. They are often viewed as upheavals to the evolutionary process. In contrast, this paper supports the hypothesis that although they are unpredictably destructive, extinction ...
