The misunderstood sixth mass extinction

  title={The misunderstood sixth mass extinction},
  author={Gerardo Ceballos and Paul R. Ehrlich},
  pages={1080 - 1081}
Scientific misunderstanding about the nature and consequences of the sixth mass extinction has led to confusion among policy-makers and the public. Scientists agree that there have been five mass extinctions in the past 600 million years ([ 1 ][1]). Although scientists also agree that Earth is now 
Discussion: Early life and lessons learned from mass extinctions.
The present Discussion tries to shed light on how life arose and developed if it is important to understand biodiversity and mass extinctions to day.
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.
The end-Guadalupian (259.8 Ma) biodiversity crisis: the sixth major mass extinction?
ABSTRACT The modern loss of species diversity has been labelled the ‘sixth extinction’ subsequent to the five major mass extinctions widely recognised in the Phanerozoic geologic record – the
Advances in Quaternary Studies: The Contribution of the Mammalian Fossil Record
Explaining the multifaceted, dynamic interactions of the manifold factors that have modelled throughout the ages the evolutionary history of the biosphere is undoubtedly a fascinating and challenging
The inflated significance of neutral genetic diversity in conservation genetics
It is demonstrated that no simple general relationship exists between neutral genetic diversity and the risk of species extinction, and a better understanding of the properties of functional genetic diversity, demographic history, and ecological relationships is necessary for developing and implementing effective conservation genetic strategies.
Just preservation
We are failing to protect the biosphere. Novel views of conservation, preservation, and sustainability are surfacing in the wake of consensus about our failures to prevent extinction or slow climate

Let Earth Rebound! Conservation’s New Imperative
The status quo of a human-possessed and humanized ecosphere might be viewed as a shared “blueprint” in being widely regarded as given, normal, and even desirable. The blueprint consists of a physical
Multiple Perspectives on Biodiversity Conservation: From Concept to Heated Debate
This chapter will initially explore the concept of biodiversity and its different interpretations, owing to its extensive and varied use since the 1990s. In addition to the well-known definition

This commentary focuses the ways in which microbes, as an essential part of all ecosystems, provide a vital link between personal and planetary systems, and mediate the biopsychosocial aspects of the authors' individualized experience—and thus health—over their life course journey.


Has the Earth’s sixth mass extinction already arrived?
Differences between fossil and modern data and the addition of recently available palaeontological information influence understanding of the current extinction crisis, and results confirm that current extinction rates are higher than would be expected from the fossil record.
Mass Extinctions and Their Aftermath
In this text the demise of the dinosaurs is put into the proper context of other extinction events and all proposed extinction mechanisms - climate change, meteorite impact, volcanisms - are critically assessed.
Accelerated modern human–induced species losses: Entering the sixth mass extinction
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.

World Scientists’ Warning to Humanity: A Second Notice
Twenty-five years ago, the Union of Concerned Scientists and more than 1700 independent scientists, including the majority of living Nobel laureates in the sciences, penned the 1992 "World
Defaunation in the Anthropocene
Defaunation is both a pervasive component of the planet’s sixth mass extinction and also a major driver of global ecological change.
The biodiversity of species and their rates of extinction, distribution, and protection
The biodiversity of eukaryote species and their extinction rates, distributions, and protection is reviewed, and what the future rates of species extinction will be, how well protected areas will slow extinction Rates, and how the remaining gaps in knowledge might be filled are reviewed.

Approaches to Macroevolution: 2. Sorting of Variation, Some Overarching Issues, and General Conclusions
Progress is being made on two of the key ones: (a) the integration of variation-generating mechanisms and the multilevel sorting processes that act on that variation, and (b) the Integration of paleontological and neontological approaches to historical biology.
More than 75 percent decline over 27 years in total flying insect biomass in protected areas
This analysis estimates a seasonal decline of 76%, and mid-summer decline of 82% in flying insect biomass over the 27 years of study, and shows that this decline is apparent regardless of habitat type, while changes in weather, land use, and habitat characteristics cannot explain this overall decline.
