The classical view is that aging happens because of random wear and tear.
However, diversity of simulated forest patches declined over time largely because of random dynamics acting on small, isolated populations.
And is it stronger or weaker in terms of its resistance to failure because of random problems or actual attack.
The surveys were, he finds, more closely bunched around the prediction of a Conservative-Labour dead heat than should have been expected, because of random variation alone.
Of course, if there are enough competing stories, some of them will fit or predict some real-world events, if only because of random luck.
In heterogeneous landscapes, habitat clumping does not influence global dispersers because of random establishment, although it does promote the persistence of local dispersers, especially under severe habitat degradation.
Population models of filamentous morphology are difficult to solve because of random fragmentation, which introduces an integral term into the population balance equations.
First, to the extent that the original sample was off the mark because of random variance, the new one will be also.
In the wild, differences between individuals in a population (of finches, fish or people) arise because of random genetic mutations and sexual reproduction.
It is a continuing process of change, forced by what Wallace and Darwin, his more famous colleague, called "natural selection". In this process, species evolve because of random mutations and selection by environmental stresses.
The expression is verified, but it turns out that it can be rather time-consuming to predict the random error reliably under extreme conditions because of random errors in the predicted error itself.
