Re: Sex Ratios

As an aside on this topic, I vaguely remember reading somewhere that deer in the wild
vary the sex of offspring based on food availability. IIRC, when food was plentiful, the
does would have more males, but when food got scarce, more females would be born. I assume
this has to do with the amount of growth either sex has to do in order to be successful
a reproducing. When there is less food, a female has a better chance of reaching maturity and
reproducing, because she does not have to be as large to win the right to mate. Could something 
similar has influenced the apistos sex distribution?
