Aim Phylogenetic endemism (PE) identifies geographic concentrations of evolutionarily
isolated and spatially restricted biota. Locations with high PE hold elements of biodiversity …

Abstract Between 50,000 and 3,000 years before present (BP) 65% of mammal genera
weighing over 44 kg went extinct, together with a lower proportion of small mammals. Why …

Extinction from habitat loss is the signature conservation problem of the twenty-first century.
Despite its importance, estimating extinction rates is still highly uncertain because no proven …

In their paper Malcolm et al.(2006) use climate-warming scenarios to estimate up to 43%
loss of species within biodiversity hotspots. This prediction is based on a climate-envelope …

Conservation biologists have identified threats to the survival of about a quarter of the
mammalian species; to identify patterns of rarity and commonness of mammals, we studied …

Species differ in their biological susceptibility to extinction, but the set of traits determining
susceptibility varies across taxa. It is yet unclear which patterns are common to all taxa, and …

Current levels of endangerment and historical trends of species and habitats are the main
criteria used to direct conservation efforts globally. Estimates of future declines, which might …

Here, I use published mortality data from 56 natural populations of mammals to examine
evidence for senescence, an increase in the probability of mortality with age. Data on extent …

1. Conservation biology has two threads: the small-population paradigm which deals with
the effect of smallness on the persistence of a population, and the declining-population …
