What biological attributes predispose species to the risk of extinction? There are many hypotheses but so far there has been no systematic analysis for discriminating between them. Using complete phylogenies of contemporary carnivores and primates, we present, to our knowledge, the first comparative test showing that high trophic level, low population density, slow life history and, in particular, small geographical range size are all significantly and independently associated with a high… 

Figures and Tables from this paper

Variability in life-history and ecological traits is a buffer against extinction in mammals.

The findings reveal the role of local variation among populations, particularly of large mammals, as a buffering mechanism against extinction, and emphasise the importance of considering trait variation in comparative analyses and conservation management.

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

Geographical range size, human population density and latitude were the most consistently significant predictors of extinction risk, but otherwise there was little evidence for general, prescriptive indicators of high extinction risk across mammals.

Multiple Causes of High Extinction Risk in Large Mammal Species

The disadvantages of large size are greater than generally recognized, and future loss of large mammal biodiversity could be far more rapid than expected.

Species traits predict extinction risk across the Tree of Life

This study suggests that in the absence of data on the precise distribution and population trends of species, traits can be used as predictors of extinction risk and thus help guide future research, monitoring and conservation efforts.

Range size dynamics can explain why evolutionarily age and diversification rate correlate with contemporary extinction risk in plants

It is found that a greater proportion of species were threatened by extinction in younger and faster-diversifying genera, suggesting that range size dynamics may explain differing patterns of extinction risk across the ToL with consequences for biodiversity conservation.

Extinction risk and population declines in amphibians

The overall distribution of threatened amphibians remained taxonomically non-random when species of unknown conservation status were omitted, and significant selectivity was detected not only at a global geographic scale, but also in country and site-specific data sets.

Doomed to die? Predicting extinction risk in the true hawks Accipitridae

It was found that species with less habitat specialization, a larger clutch size and more plumage polymorphism were associated with lower extinction risk and larger population and range sizes, and no single factor is likely to be sufficient when predicting the threat of extinction.

Ecological correlates of extinction risk in Chinese terrestrial mammals

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. For effective

Trait-based prediction of extinction risk across terrestrial taxa

A systematic review of the relation between species traits and extinction risk

Two complementary paths to better understand extinction risk dynamics are proposed: the simulation of virtual species and settings for theoretical insights, and the use of comprehensive and comparable empirical data representative of all taxa and regions under a unified study.



Extinction Vulnerability and Selectivity: Combining Ecological and Paleontological Views

This work has shown that replacement of vulnerable taxa by rapidly spreading taxa that thrive in human-altered environments will ultimately produce a spatially more homogenized biosphere with much lower net diversity.

Nonrandom extinction and the loss of evolutionary history.

It is estimated that the prospective extra loss of mammalian evolutionary history alone would be equivalent to losing a monotypic phylum, and the potentially severe implications of the clumped nature of threat for the loss of biodiversity are shown.

Edge effects and the extinction of populations inside protected areas

The species most likely to disappear from small reserves are those that range widely-and are therefore most exposed to threats on reserve borders-irrespective of population size, so that border areas represent population sinks.

Ecological Correlates of Extinction Proneness in Australian Tropical Rain Forest Mammals

The results highlight the importance of tolerance of modijied habitats in determining survival of nonpying mammals in tropical forest fragments and the implications for hopical forest conservation.

Flight areas of British butterflies: assessing species status and decline

Geographical range size is a key ecological variable, but the consequences of measuring range size in different ways are poorly understood. We use high–resolution population data from British

Dynamic biogeography and conservation of endangered species

It is reported that observed patterns of range contraction do not support the above predictions and that most species examined persist in the periphery of their historical geographical ranges, with the core populations persisting until the final stages of decline.

Present and Future Taxonomic Selectivity in Bird and Mammal Extinctions

We compared the distribution of historical bird and mammal species extinctions across genera and families with the distribution we would expect if these extinctions had occurred at random with


The history of carnivorous mammals is characterized by a series of rise-and-fall patterns of diversification in which declining clades are replaced by phylogenetically distinct but functionally similar clades, which reflects the tendency for clades of large carnivorous mamm...

Relative risk of extinction of passerine birds on continents and islands

This work compiles the ranges of thepasserine (perching) birds of the Americas to produce a map showing where species losses might occur in the long term.

Resilience and conservation of large carnivores in the Rocky Mountains

Large carnivores evolved behaviors and life-history traits that conferred resilience to environmental disturbances at various temporal and spatial scales. We synthesize empirical information for each
