The Sixth Mass Extinction: fact, fiction or speculation?
Biological Reviews of The Cambridge Philosophical Society, 2022 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 be underway, this time caused entirely by humans.

Frontiers in Ecology and Evolution, 2022 The colonization of Mauritius exemplifies the role played by humans in altering the ecosystems of remote oceanic islands. This paper focuses on how we study those islands first colonized under the global mantle of colonialism.

Neuron, 2015 Extinction serves as the leading theoretical framework and experimental model to describe how learned behaviors diminish through absence of anticipated reinforcement. In the past decade, extinction has moved beyond the realm of associative learning theory and behavioral experimentation in animals and has become a topic of considerable interest in the ...

Journal of Threatened Taxa, 2018 Ex situ management of wildlife provides a possibility for species maintenance, research development and environmental education. But as captive facilities are usually much smaller than the area occupied by a species in the natural habitat, cleaning ...

Vertebrates on the brink as indicators of biological annihilation and the sixth mass extinction
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance The ongoing sixth mass extinction may be the most serious environmental threat to the persistence of civilization, because it is irreversible.

Accelerated modern human–induced species losses: Entering the sixth mass extinction
Science Advances, 2015 Humans are causing a massive animal extinction without precedent in 65 million years. The oft-repeated claim that Earth’s biota is entering a sixth “mass extinction” depends on clearly demonstrating that current extinction rates are far above the ...

Recent responses to climate change reveal the drivers of species extinction and survival
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance The response of species to climate change is of increasingly urgent importance. Here, we address the specific changes in climate that were associated with recent population extinctions, using data from 538 plant and animal species ...

AIMS Neuroscience, 2021 We aimed to investigate the persistent trace of one traumatic event on neurocircuit controls in rats. Conditioning was reflected by reductions in rates of ‘freezing’ and ‘other-than-freezing’ motor activities, between which rats could alternate on ...
