25) Here, g translates the measures Z of the density-independent factors involved into their effects on R t • For simplicity, however, g(Z) may be denoted by z. e. 26) Assume, for simplicity and without loss of generality in conclusion, that {Zt} is a stationary stochastic process with the mean Jiz and autocovariances yzz(j). l5d), we see that the regulation of the population requires lim t L t-OOj=l (l-jjt)Yzz(j)= -(lj2)YzAO). 6). However, such a theoretical mechanism of population regulation is fragile and, hence, is unlikely to exist in the real world, as explained below.

11), we find: = tYRR(O) + 2 t I (t-j)YRR(j)+(tfiR)2~A. 20) For t---+ 00, the right-hand side will vanish. It follows that the left-hand side, because it is non-negative, must also vanish. 8b), fiR is infinitesimal of order t- 1 at most, so that the last quotient on the left-hand side will vanish. 22) 20 Basic properties and structure of population processes So far, I have considered only the present-to-future section of the time series {R t }, that is, that the time series starts at t = 0 and extends only to the future.

33) as in Fig. 7. The point is, however, that the difference will show up when the two processes are subjected to random perturbation. 37) is robust, as we see below. Because we cannot by any practical means build a perfect control box for the environmental chamber, some error is inevitable. Let us assume that the error is uncorrelated. 39) respectively. 39) are no longer equivalent to each other in their statistical characteristics. As shown in Fig. 39) appears much the same as the preperturbation series in Fig.
