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 …

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 …

Understanding why some species are at high risk of extinction, while others remain relatively
safe, is central to the development of a predictive conservation science. Recent studies have …

Global species extinction typically represents the endpoint in a long sequence of population
declines and local extinctions. In comparative studies of extinction risk of contemporary …

Around one quarter of mammalian species and one eighth of bird species are listed by IUCN
as threatened with extinction (Hilton-Taylor 2000); the other species, however, seem not to …

Phylogenetic information is becoming a recognized basis for evaluating conservation
priorities, but associations between extinction risk and properties of a phylogeny such as …

It is well established that different species vary in their vulnerability to extinction risk and that
species biology can underpin much of this variation. By contrast, very little is known about …

Conservation biologists always wish they had more information. Which populations are most
vulnerable to extinction? What processes threaten them? What do they need to recover …

It is becoming increasingly clear that species of smaller body size tend to be less vulnerable
to contemporary extinction threats than larger species, but few studies have examined the …

Extinction is rarely random across ecological and geological time scales. Traits that make
some species more extinction-prone include individual traits, such as body size, and …
