Recent extinction rates are 100 to 1000 times their pre-human levels in well-known, but taxonomically diverse groups from widely different environments. If all species currently deemed "threatened" become extinct in the next century, then future extinction rates will be 10 times recent rates. Some threatened species will survive the century, but many species not now threatened will succumb. Regions rich in species found only within them (endemics) dominate the global patterns of extinction… 
Comparing Extinction Rates: Past, Present, and Future
The last centuries were marked by a steep increase of human population and by the intensification of anthropogenic impacts on ecosystems and natural communities. Today, the rate of species extinction
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.
Extinction rates of North American freshwater fauna
Since 1900, 123 freshwater animal species have been recorded as extinct in North America. Hun- dreds of additional species of fishes, mollusks, crayfishes, and amphibians are considered imperiled.
Biodiversity and extinction
Introduction extract: Species-level conservation activities tend to be focused on those species that are highly threatened with global or regional extinction in the near future. This is broadly
Threatened and endangered species geography: characteristics of hot spots in the conterminous United States
TLDR
An estimated global extinction rate that appears to be unprecedented in geological time has heightened concern for the increasing number of rare species and rarity has been used as an important criterion for identifying which species should be the focus of conservation efforts.
Extinctions of Threatened Frogs may Impact Ecosystems in a Global Hotspot of Anuran Diversity
Abstract Human activity is accelerating rates of extinction around the world, and there is therefore an urgent need to understand the potential consequences of species loss on functional diversity
Global Biodiversity Conservation: The Critical Role of Hotspots
Global changes, from habitat loss and invasive species to anthropogenic climate change, have initiated the sixth great mass extinction event in Earth’s history. As species become threatened and
Future threats to biodiversity and pathways to their prevention
TLDR
Proactive international efforts to increase crop yields, minimize land clearing and habitat fragmentation, and protect natural lands could increase food security in developing nations and preserve much of Earth's remaining biodiversity.
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.

Prehistoric Extinctions of Pacific Island Birds: Biodiversity Meets Zooarchaeology
TLDR
On tropical Pacific islands, a human-caused "biodiversity crisis" began thousands of years ago and has nearly run its course and the current global extinction crisis therefore has historic precedent.
Threatened biotas: "Hot spots" in tropical forests
  • N. Myers

TLDR
10 areas that, a) are characterised by exceptional concentrations of species with high levels of endemism and b) are experiencing unusually rapid rates of depletion are identified, so conservationists can engage in a more systematised response to the challenge of largescale extinctions impending in tropical forests.
Geographical Trends in Numbers of Species
TLDR
A quantitative analysis of geographic trends in species density for the terrestrial vertebrate faunas of the United States and Australia reveals general patterns as well as intriguing and profound differences in vertebrate distributions.

Discussion of Pimm et al., 1994 (Bird Extinctions in the Central Pacific [and Discussion])
TLDR
Cautions are suggested against the conclusion that all human colonists or islands necessarily cause substantial extinctions of vertebrates, rather than the general idea that humans necessarily are destructive of biodiversity.

TLDR
Two recent papers on mammals by Mares and Pagel et al. illustrate the complex biological issues involved in predicting what diversity might remain after future planners have taken a cookie cutter to their wilderness.

TLDR
Observations suggest that lifetimes of the 'Alala (now reduced to about three pairs in the wild), and of populations of Northern Spotted Owl in the smallest forest fragments, will be short unless active management is implemented.

TLDR
By concentrating on these hot-spot areas where needs are greatest and where the pay-off from safeguard measures would be greatest, conservationists can engage in a more systematised response to the challenge of large scale impending extinctions.
