However, in randomly fluctuating environmental conditions the correlation between the age of frozen species and their probability of extinction is probably rather loose.
Of course, even among the frozen species, the older species are probably more obsolete then younger species and therefore have a higher probability of extinction.
The report assumes that the probability of extinction is 0.1percentt per year.
The effect of spatial structure on the probability of extinction was greater in binary landscapes.
Even if the probability of extinction were merely 5%, or 1%, it would still be worth taking seriously in view of how much is at stake".
It contains explicit criteria and categories to classify the conservation status of individual species on the basis of their probability of extinction.
Finally, we conducted a population viability analysis to determine the probability of extinction associated with varying management strategies.
Their efficacy was assessed on model outputs such as the prevalence and probability of extinction at the metapopulation level.
Four traits increased the probability of extinction: smaller group size, higher background mortality, lower transmission rate and more costly traits (although costly traits sometimes reached an equilibrium).
A species listed as "threatened" has a high probability of extinction in the wild within the next few decades if nothing is done to prevent it).
Under current drought frequencies, A. bibullatus' probability of extinction was minimized with the most frequent management, since open habitats promote recruitment.
