Extinction risk in the sea

Trends in Ecology & Evolution, 1999
Jean Baptiste de Lamarck and Thomas Huxley, two of the foremost thinkers of the 18th and 19th centuries, believed that humanity could not cause the extinction of marine species. Their opinions reflected a widespread belief that the seas were an inexhaustible source of food and wealth of which people could barely use a fraction.

Extinction Risk and Conservation Priorities

Science, 2006
Threatened species lists based on extinction risk are becoming increasingly influential for setting conservation priorities at regional, national, and local levels. Risk assessment, however, is a scientific endeavor, whereas priority setting is a societal process, and they should not be ...

Population Variability and Extinction Risk

Conservation Biology, 2000
Abstract: 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 ...

Metapopulation extinction risk: Dispersal’s duplicity

Theoretical Population Biology, 2009
Metapopulation extinction risk is the probability that all local populations are simultaneously extinct during a fixed time frame. Dispersal may reduce a metapopulation's extinction risk by raising its average per-capita growth rate. By contrast, dispersal may raise a metapopulation's extinction risk by reducing its average population density.

Inferring extinction risks from sighting records

Journal of Theoretical Biology, 2013
Estimating the probability that a species is extinct based on historical sighting records is important when deciding how much effort and money to invest in conservation policies. The framework we offer is more general than others in the literature to date.

Extinction and Risk

SSRN Electronic Journal, 2012
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, 2000
Extinction 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.

Extinction: Complexity of Assessing Risk

Science, 2001
In discussing the extinction risk of naive prey species confronted by reintroduced predators ( Science 's Compass, 9 Feb., p. [997][1]), J. L. Gittleman and M. E. Gompper say that, apparently because of diverse anthropogenic impacts, “a markedly higher proportion of ungulate species compared ...
