The population extinction pulse we describe here shows, from a quantitative viewpoint, that Earth's sixth mass extinction is more severe than perceived when looking exclusively at species extinctions. [...] Key Method That conclusion is based on analyses of the numbers and degrees of range contraction (indicative of population shrinkage and/or population extinctions according to the International Union for Conservation of Nature) using a sample of 27,600 vertebrate species, and on a more detailed analysis…Expand
Vertebrates on the brink as indicators of biological annihilation and the sixth mass extinction
TLDR
The human-caused sixth mass extinction is likely accelerating for several reasons, including: many of the species that have been driven to the brink will likely become extinct soon, and the distribution of those species highly coincides with hundreds of other endangered species, surviving in regions with high human impacts, suggesting ongoing regional biodiversity collapses.

The Sixth Mass Extinction Crisis and its Impact on Biodiversity and Human Welfare
“Earth provides enough to satisfy every man’s needs, but not every man’s greed” - Mahatma Gandhi The vast number of species prevailing on planet Earth is the result of evolutionary processes thatExpand
Co-extinctions annihilate planetary life during extreme environmental change
TLDR
It is shown how ecological dependencies amplify the direct effects of environmental change on the collapse of planetary diversity by up to ten times. Expand
Thinking about the Biodiversity Loss in This Changing World
Extinction of species has been a recurrent phenomenon in the history of our planet, but it was generally outweighed in the course of quite a long geological time by the appearance of new species,Expand
The dynamics underlying avian extinction trajectories forecast a wave of extinctions
TLDR
It is estimated that global conservation efforts have reduced the effective extinction rate by 40%, but mostly through preventing critically endangered species from going extinct rather than by preventing species at low risk from moving into higher-risk categories. Expand
Collapse of Terrestrial Biodiversity
Societies’ very survival depends on their ability to avert the impending threat of biological annihilation via the ongoing sixth mass extinction of species, which has intensified over the last 50Expand
Are Insects Heading Toward Their First Mass Extinction? Distinguishing Turnover From Crises in Their Fossil Record
Abstract Time and again, over hundreds of millions of years, environmental disturbances have caused mass extinctions of animals ranging from reptiles to corals. The anthropogenic loss of speciesExpand
Conserving the abundance of nonthreatened species

TLDR
Research should focus on characterizing the effects of local declines in species that are not threatened globally across a range of ecosystem services and quantifying the spatial distribution of these effects through the distribution of abundance. Expand
Wilderness areas halve the extinction risk of terrestrial biodiversity
TLDR
The persistence probability of biodiversity is modeled, combininghabitat condition with spatial variation in species composition, to show that retaining these remaining wilderness areas is essential for the international conservation agenda. Expand

TLDR
There is an urgent need for concerted global action to reduce and reverse this trend of environmental degradation and thus conserve the authors' biological diversity and ecosystem services to protect ourselves and their Planet. Expand

Accelerated modern human–induced species losses: Entering the sixth mass extinction
TLDR
Estimates of extinction rates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way and a window of opportunity is rapidly closing. Expand
The Sixth Extinction Crisis Loss of Animal Populations and Species
TLDR
There is an explosion of descriptions of new species even in previously "well-known" groups such as mammals, suggesting that previous estimates of the magnitude of biodiversity may be too low. Expand
Global biodiversity gain is concurrent with declining popula - tion sizes
TLDR
By using extinction records for well-known animal groups plus surrogate data, it is shown there is no evidence for an unusually high rate of extinction, a mass extinction is not yet underway, and there are indications of a continued biodiversity gain. Expand
Vertebrate biodiversity losses point to a sixth mass extinction
TLDR
Fuzzy arithmetic was used to compare recent vertebrate extinction reported in the 2012 IUCN/SSC Red List with biodiversity losses at the end of K–Pg, and extreme values and the great speed with which vertebrate biodiversity is being decimated are comparable to the devastation of previous extinction events.

Mass extinction in poorly known taxa
TLDR
It is estimated that the authors may already have lost 7% of the species on Earth and that the biodiversity crisis is real, based on extrapolation from a random sample of land snail species via two independent approaches. Expand

TLDR
Defaunation is both a pervasive component of the planet’s sixth mass extinction and also a major driver of global ecological change. Expand

Are we in the midst of the sixth mass extinction? A view from the world of amphibians
TLDR
A general message from amphibians is that the authors may have little time to stave off a potential mass extinction, and it is shown that salamanders on tropical mountains are particularly at risk. Expand
Mammal Population Losses and the Extinction Crisis
TLDR
Historic and present distributions of 173 declining mammal species from six continents are compared, finding that these species have collectively lost over 50% of their historic range area, mostly where human activities are intensive. Expand
Patterns, Causes, and Consequences of Anthropocene Defaunation
TLDR
Slowing defaunation will require aggressively reducing animal overexploitation and habitat destruction; mitigating climate disruption; and stabilizing the impacts of human population growth and uneven resource consumption. Expand
