The threatened status of restricted-range coral reef fish species [PDF]

open access: yes, 2000
Coral reefs are the most diverse ecosystem in the sea. Throughout the world they are being overfished, polluted and destroyed, placing biodiversity at risk.

Accelerated mass extinction in an isolated biota during Late Devonian climate changes

open access: yesScientific Reports, 2021
The fossil record can illuminate factors that contribute to extinction risk during times of global environmental disturbance; for example, inferred thermal tolerance was an important predictor of extinction during several mass extinctions that ...

Quantification of habitat fragmentation reveals extinction risk in terrestrial mammals [PDF]

open access: yes, 2017
Although habitat fragmentation is often assumed to be a primary driver of extinction, global patterns of fragmentation and its relationship to extinction risk have not been consistently quantified for any major animal taxon.

Environmental and anthropogenic constraints on animal space use drive extinction risk worldwide.

open access: yesEcology Letters, 2021
Animals require a certain amount of habitat to persist and thrive, and habitat loss is one of the most critical drivers of global biodiversity decline. While habitat requirements have been predicted by relationships between species traits and home-range ...

Conservation genetics – science in the service of nature

open access: yesActa Biologica, 2020
Conservation genetics is a subdicipline of conservation biology which deals with the extinction risk and many other problems of nature conservation by using genetic tools and techniques.

Relative Importance of Ecological, Evolutionary and Anthropogenic Pressures on Extinction Risk in Chinese Angiosperm Genera

open access: yesFrontiers in Ecology and Evolution, 2022
China has many threatened plant species, which are exposed to environmental degradation and other anthropogenic pressures. We assessed support for potential extinction pathways in Chinese angiosperm genera and quantified possible threats to phylogenetic ...

Climate change and the selective signature of the Late Ordovician mass extinction [PDF]

open access: yes, 2012
Selectivity patterns provide insights into the causes of ancient extinction events. The Late Ordovician mass extinction was related to Gondwanan glaciation; however, it is still unclear whether elevated extinction rates were attributable to record ...

Human population density and extinction risk in the world's carnivores. [PDF]

open access: yesPLoS Biology, 2004
Understanding why some species are at high risk of extinction, while others remain relatively safe, is central to the development of a predictive conservation science.

Morphological traits of reef corals predict extinction risk but not conservation status

open access: yesGlobal Ecology and Biogeography, 2021
Aim The current assessment of extinction risk in reef corals by the International Union for Conservation of Nature (IUCN) has been criticized, because coral life-history traits associated with resilience are not reflected in the conservation status.

Ecological and Conservation Correlates of Rarity in New World Pitvipers

open access: yesDiversity, 2019
Rare species tend to be especially sensitive to habitat disturbance, making them important conservation targets. Thus, rarity patterns might be an important guide to conservation efforts.
