- In this context, would any positive power > 1 of the prey density in the
denominator be treatable in the same manner? Would the proofs just carry
over?(Õâ¾ä»°Ã»¿´¶®Òâ˼£¿)

- Also in the introduction, I would find it useful to first describe the
simple mean-field rate equation solutions (in the absence of Brownian
noise). These could then compared in Sec.5 with the numerical simulations.
It seems that the population densities shown in Figs. 1-3 fluctuate about
their mean given by basically the rate equation solutions. Are the
associated variances given just be the noise correlator strengths?

- Are the plots obtained with just a single noise history realization
each? Shouldn't there be averages over a sufficiently large number of
noise histories? Are there periodicities in the data, which could be
uncovered by temporal Fourier transforms? Are the predators in Fig. 3
truly becoming extinct? The data shown is not clear - there could be a
population recovery as in earlier times.
