Phylogenetically clustered extinction risks do not substantially prune the Tree of Life. [PDF]

open access: yesPLoS ONE, 2011
Anthropogenic activities have increased the rate of biological extinction many-fold. Recent empirical studies suggest that projected extinction may lead to extensive loss to the Tree of Life, much more than if extinction were random.

Permian-Triassic insect diversity revealed by fossils from China [PDF]

open access: yesBIO Web of Conferences, 2023
Most of the research on Paleoentomology focuses on describing morphology and classification of one species of fossil insects. However, there is little information on the temporal diversity of insects during the Permian and Triassic periods.

Biological traits of seabirds predict extinction risk and vulnerability to anthropogenic threats

open access: yesbioRxiv, 2020
Aim Here we aim to: 1) test whether globally-threatened vs non-threatened seabirds are separated in trait space; 2) quantify the redundancy and uniqueness of species trait combinations per IUCN Red List Category; and 3) identify traits that render ...

The ethics of species extinctions

open access: yesCambridge Prisms: Extinction, 2023
This review provides an overview of the ethics of extinctions with a focus on the Western analytical environmental ethics literature. It thereby gives special attention to the possible philosophical grounds for Michael Soulé’s assertion that the untimely

The Intensification of Prolonged Cooling Climate-Exacerbated Late Ordovician–Early Silurian Mass Extinction: A Case Study from the Wufeng Formation–Longmaxi Formation in the Sichuan Basin

open access: yesJournal of Marine Science and Engineering, 2023
The Late Ordovician–Early Silurian period was a significant transitional phase in geological history and has garnered global interest. This study focuses on the black shale series of the Wufeng Formation–Longmaxi Formation of the Upper Ordovician–Lower ...

Extinction in neutrally stable stochastic Lotka-Volterra models [PDF]

open access: yes, 2012
Populations of competing biological species exhibit a fascinating interplay between the nonlinear dynamics of evolutionary selection forces and random fluctuations arising from the stochastic nature of the interactions.

Circling the drain: the extinction crisis and the future of humanity

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2022
Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centred on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although ...

Bistability induced by generalist natural enemies can reverse pest invasions [PDF]

open access: yes, 2016
Reaction-diffusion analytical modeling of predator-prey systems has shown that specialist natural enemies can slow, stop and even reverse pest invasions, assuming that the prey population displays a strong Allee effect in its growth.

Over half of threatened species require targeted recovery actions to avert human‐induced extinction

open access: yesFrontiers in Ecology and the Environment, 2022
Averting human-induced extinctions will require strong policy commitments that comprehensively address threats to species. A new Global Biodiversity Framework is currently being negotiated by the world’s governments through the Convention on Biological ...

Potential landscape-scale pollinator networks across Great Britain: structure, stability and influence of agricultural land cover [PDF]

open access: yes, 2018
Understanding spatial variation in the structure and stability of plant-pollinator networks, and their relationship with anthropogenic drivers, is key to maintaining pollination services and mitigating declines.
