Population Variability and Extinction Risk
Conservation Biology, 2000Abstract: Population models generally predict increased extinction risk (ER) with increased population variability ( PV ), yet some empirical tests have provided contradictory findings. We resolve this conflict by attributing negative measured relationships to a statistical artifact that arises because PV ...

Brazilian killifishes risk extinction
Science, 2018The annual killifishes are a diversified group of small fish in Africa and South America ([ 1 ][1]). Annual killifish are unique in their ability to survive in ephemeral pools; they have short, seasonal life cycles, laying eggs that lie dormant in the soil once the pools have evaporated and ...

This is an early portion of a forthcoming work of practical moral philosophy, one arguing that humanity, as a species, should want to survive. This particular piece argues that neo-classical economics places an emphasis on short-term gain over precaution and in doing so places lives of individual humans — and even the species itself — at risk.

Extinction Risk in Endemic Marine Fishes
Conservation Biology, 2011[Extract] Developing effective management strategies for conserving species requires identifying the species with the greatest probability of extinction and determining why the probabilities are high. In terrestrial systems, endemic island species have the highest rates of extinctions (Frankham 1998; Whittaker 1998).

Comparing Risk Factors for Population Extinction
Journal of Theoretical Biology, 2000Extinction risk of natural populations of animals and plants is enhanced by many different processes, including habitat size reduction and toxic chemical exposure. We develop a method to evaluate different risk factors in terms of the decrease in the mean extinction time.

The Consistency of Extinction Risk Classification Protocols
Conservation Biology, 2005Abstract: Systematic protocols that use decision rules or scores are seen to improve consistency and transparency in classifying the conservation status of species. When applying these protocols, assessors are typically required to decide on estimates for attributes that are inherently uncertain. Input data and

Biological Correlates of Extinction Risk in Bats
The American Naturalist, 2003(Uploaded by Plazi for the Bat Literature Project) We investigated patterns and processes of extinction and threat in bats using a multivariate phylogenetic comparative approach. Of nearly 1,000 species worldwide, 239 are considered threatened by the International Union for Conservation of Nature and Natural Resources (IUCN) and 12 are extinct.

Greenland sled dogs at risk of extinction
Science, 2018Dog ( Canis familiaris ) and sled remains found together suggest that the first sled dogs arose approximately 10,000 years ago ([ 1 ][1]). The ancestors to current sled dog breeds were essential to the Inuit's conquest of the Arctic. Sled dogs provided the main transport and hunting platform ([ 2 ][
