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 …

Because of human action, the Earth has entered an era where profound changes in the
global environment are creating novel conditions that will be discernable far into the future …

Here we build on the manifesto 'World Scientists' Warning to Humanity, issued by the
Alliance of World Scientists. As a group of conservation biologists deeply concerned about …

Long-term data allow ecologists to assess trajectories of population abundance. Without this
context, it is impossible to know whether a taxon is thriving or declining to extinction. For …

Found throughout the tree of life and in every ecosystem, parasites are some of the most
diverse, ecologically important animals on Earth—but in almost all cases, the least protected …

Terrestrial mammals are experiencing a massive collapse in their population sizes and
geographical ranges around the world, but many of the drivers, patterns and consequences …

Although theory identifies coextinctions as a main driver of biodiversity loss, their role at the
planetary scale has yet to be estimated. We subjected a global model of interconnected …

The effects of the present biodiversity crisis have been largely focused on the loss of
species. However, a missed component of biodiversity loss that often accompanies or even …

Climate, physical landscapes, and biota interact to generate heterogeneous hydrologic
conditions in space and over time, which are reflected in spatial patterns of species …

Biotic interactions drive key ecological and evolutionary processes and mediate ecosystem
responses to climate change. The direction, frequency, and intensity of biotic interactions …
