Digging the pupfish out of its hole: risk analyses to guide harvest of Devils Hole pupfish for captive breeding. [PDF]

open access: yes, 2014
The Devils Hole pupfish is restricted to one wild population in a single aquifer-fed thermal pool in the Desert National Wildlife Refuge Complex. Since 1995 the pupfish has been in a nearly steady decline, where it was perched on the brink of extinction ...

Extinction risk and conservation of the world’s sharks and rays [PDF]

open access: yeseLife, 2013
The rapid expansion of human activities threatens ocean-wide biodiversity. Numerous marine animal populations have declined, yet it remains unclear whether these trends are symptomatic of a chronic accumulation of global marine extinction risk.

Tracking the rising extinction risk of sharks and rays in the Northeast Atlantic Ocean and Mediterranean Sea

open access: yesScientific Reports, 2021
The loss of biodiversity is increasingly well understood on land, but trajectories of extinction risk remain largely unknown in the ocean. We present regional Red List Indices (RLIs) to track the extinction risk of 119 Northeast Atlantic and 72 ...

Estimating IUCN Red List population reduction: JARA—A decision‐support tool applied to pelagic sharks

open access: yesConservation Letters, 2020
The International Union for Conservation of Nature's (IUCN) Red List is the global standard for quantifying extinction risk but assessing population reduction (criterion A) of wide‐ranging, long‐lived marine taxa remains difficult and controversial.

Imperfect detection biases extinction‐debt assessments

open access: yesConservation Science and Practice, 2021
Freshwater ecosystems have been substantially altered, threatening the survival and recovery of aquatic species at risk. Estimating the likelihood and magnitude of future extinctions (extinction debt; ED) is integral for conserving biodiversity and ...

IUCNN - deep learning approaches to approximate species’ extinction risk

open access: yesbioRxiv, 2021
Aim The global Red List (RL) from the International Union for the Conservation of Nature is the most comprehensive global quantification of extinction risk, and widely used in applied conservation as well as in biogeographic and ecological research. Yet,

What does a threatened saproxylic beetle look like? Modelling extinction risk using a new morphological trait database.

open access: yesJournal of Animal Ecology, 2021
The extinction of species is a non-random process, and understanding why some species are more likely to go extinct than others is critical for conservation efforts. Functional trait-based approaches offer a promising tool to achieve this goal.

Global analysis of threat status reveals higher extinction risk in tropical than in temperate bird sister species [PDF]

open access: yes, 2019
Given increasing pressures upon biodiversity, identification of species’ traits related to elevated extinction risk is useful for more efficient allocation of limited resources for nature conservation.

How predictable are mass extinction events?

open access: yesRoyal Society Open Science, 2023
Many modern extinction drivers are shared with past mass extinction events, such as rapid climate warming, habitat loss, pollution and invasive species.
