The human race faces many global to local challenges in the near future. Among these are massive biodiversity losses. The 2012 IUCN/SSC Red List reported evaluations of ~56 % of all vertebrates. This included 97 % of amphibians, mammals, birds, cartilaginous fishes, and hagfishes. It also contained evaluations of ~50 % of lampreys, ~38 % of reptiles, and ~29 % of bony fishes. A cursory examination of extinction magnitudes does not immediately reveal the severity of current biodiversity losses… 

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 species

The Sixth Mass Extinction: fact, fiction or speculation?

Differences in extinction rates are reviewed according to realms: marine species face significant threats but, although previous mass extinctions were largely defined by marine invertebrates, there is no evidence that the marine biota has reached the same crisis as the non-marine biota, and island species have suffered far greater rates than continental ones.

Trophic rewilding: impact on ecosystems under global change

There is increasing evidence that this global wildlife loss does not only imply the loss of charismatic animals but also the functions they have in ecosystems, and a novel ecological restoration technique has emerged, referred to as rewilding.

Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines

The population extinction pulse shows, from a quantitative viewpoint, that Earth’s sixth mass extinction is more severe than perceived when looking exclusively at species extinctions and humanity needs to address anthropogenic population extirpation and decimation immediately.

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

Late Pleistocene megafauna extinction leads to missing pieces of ecological space in a North American mammal community.

The conservation status of large-bodied mammals is dire. Their decline has serious consequences because they have unique ecological roles not replicated by smaller-bodied animals. Here, we use the

Seeing Red: Analyzing IUCN Red List Data of South and Southeast Asian Amphibians

In the midst of the sixth mass extinction event which is currently underway, it appears that amphibians are one of the most impacted vertebrates. Over 6,500 amphibian species are listed on the IUCN

Extinction Debt as a Driver of Amphibian Declines: An Example with Imperiled Flatwoods Salamanders

It is suggested that extinction debt is likely responsible for numerous amphibian declines and that this perspective should be incorporated into the structure of amphibian research and management.

The Challenges of Conserving Biodiversity: A Spotlight on Southeast Asia

Biodiversity is being lost at a rapid pace, mainly due to anthropogenic pressures from a growing human population. Southeast Asia is a biodiversity hotspot with high species endemism; however, it is

A lost world in Wallacea: Description of a montane archipelagic avifauna

Five new songbird species and five new subspecies found on a single small island near Sulawesi, Indonesia, over a single 6-week expedition are described, suggesting that humans’ understanding of biogeographically complex regions such as Wallacea remains incomplete.



Extinction risk and conservation of the world’s sharks and rays

Overall chondrichthyan extinction risk is substantially higher for sharks, rays, and chimaeras than for most other vertebrates, and only one-third of species are considered safe.

Are we in the midst of the sixth mass extinction? A view from the world of amphibians

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.

Human impacts on the rates of recent, present, and future bird extinctions.

The statement that approximately 1.3% of the approximately 10,000 presently known bird species have become extinct since A.D. 1500 is qualified and a 21st century rate of approximately 1,000 E/MSY is predicted, which is higher than the benchmark rate before human impacts but is a serious underestimate.

Extinctions in the fossil record

Approaches to extinction analysis and prediction based on morphological variety or biodisparity should be explored as an adjunct or alternative to taxon inventories or phylogenetic metrics.

A Cretaceous-Tertiary mass extinction? Were most of Earth's species killed off?

It is argued that the species changes at the K/T boundary were neither sudden nor catastrophic and were most likely caused by a regression of sea level that led to a decrease in primary production.

The Future of Biodiversity

Estimates of future extinctions are hampered by the authors' limited knowledge of which areas are rich in endemics, and regions rich in species found only within them (endemics) dominate the global patterns of extinction.

The end-Permian extinction was, without question, the most profound and triggered the most widespread reorganization of ecosystems and animal diversity in the past 500 million years and is largely responsible for much of the structure marine ecosystems today.

The Dodo Went Extinct (And Other Ecological Myths)

Critics challenge the scientific consensus that human impacts are driving species to extinction hundreds to thousands of times faster than expected from the natural background rate, and suggest that there have been too few recent extinctions.

Global patterns of diversification in the history of modern amphibians

A phylogenetic timetree based on a multigene data set of 3.75 kb for 171 species reveals several episodes of accelerated amphibian diversification, which do not fit models of gradual lineage accumulation.

End-Permian mass extinctions: A review

Two mass extinctions brought the Paleozoic to a close: one at the end of the Guadalupian, or middle Permian (ca. 260 Ma), and a more severe, second event at the close of the Changhsingian Stage (ca.
