Abstract
If habitat destruction or overexploitation of populations
is severe, species loss can occur directly and abruptly.
Yet the final descent to extinction is often driven by
synergistic processes (amplifying feedbacks) that can
be disconnected from the original cause of decline. We
review recent observational, experimental and meta-analytic
work which together show that owing to interacting
and self-reinforcing processes, estimates of
extinction risk for most species are more severe than
previously recognised. As such, conservation actions
which only target single-threat drivers risk being
inadequate because of the cascading effects caused by
unmanaged synergies. Future work should focus on how
climate change will interact with and accelerate ongoing
threats to biodiversity, such as habitat degradation,
overexploitation and invasive species.
