Population Viability Analysis for Endangered Roanoke Logperch [PDF]

, 2016
A common strategy for recovering endangered species is ensuring that populations exceed the minimum viable population size (MVP), a demographic benchmark that theoretically ensures low long-term extinction risk.

High Genetic Diversity in Geographically Remote Populations of Endemic and Widespread Coral Reef Angelfishes (genus: Centropyge)

Diversity, 2013
In the terrestrial environment, endemic species and isolated populations of widespread species have the highest rates of extinction partly due to their low genetic diversity.

Principles and Mechanisms of Wildlife Population Persistence in the Face of Disease

Frontiers in Ecology and Evolution, 2020
Emerging infectious diseases can result in species declines and hamper recovery efforts for at-risk populations. Generalizing considerations for reducing the risk of pathogen introduction and mitigating the effects of disease remains challenging and ...

Extinction in a branching process: Why some of the fittest strategies cannot guarantee survival [PDF]

arXiv, 2012
The fitness of a biological strategy is typically measured by its expected reproductive rate, the first moment of its offspring distribution. However, strategies with high expected rates can also have high probabilities of extinction. A similar situation is found in gambling and investment, where strategies with a high expected payoff can also have a ...

A Model of Pathways to Artificial Superintelligence Catastrophe for Risk and Decision Analysis [PDF]

, 2016
An artificial superintelligence (ASI) is artificial intelligence that is significantly more intelligent than humans in all respects. While ASI does not currently exist, some scholars propose that it could be created sometime in the future, and furthermore that its creation could cause a severe global catastrophe, possibly even resulting in human ...

Durable Anti‐fogging Polymer Coatings Based on C,H Insertion Cross–linking (CHic) That Are User and Environmentally Friendly

Advanced Materials Technologies, EarlyView.
Highly photoreactive polymer networks prevent fogging by forming uniform water films. Activated by visible light and cross‐linked by CH insertion, these coatings exhibit excellent water film formation, transparency, and durability, even after frequent washing.

Risk of Population Extinction from Periodic and Abrupt Changes of Environment

, 2008
A simulation model of a population having internal (genetic) structure is presented. The population is subject to selection pressure coming from the environment which is the same in the whole system but changes in time.
