Few humans doubt that the mother's milk offers the simplest nutrients for the full-terrn baby throughout the first few months of existence, while the digestive, absorptive and excretory structures are particularly immature. The increase ment of the digestive enzymes is designated in bankruptcy four. the importance of this immaturity first emerged because of the pioneering paintings of Professor Robert McCance and Dr Elsie Widdowson in human nutrients, once they studied the electrolyte and nitrogen excretion of infants and younger animals.

If the disease develops explosively, affecting a large number of individuals, it may spread to a new region where it will have the character once again of a progressive epidemic. Population bursts of fungi occur when diseased seeds are planted, or the fungus that has invaded the alternate host emerges. Shoots become diseased and the fungus spreads throughout the field from these primary diseased shoots; the fungus must increase about a billion-fold in order to destroy all the fields in the vicinity.

Since it is detectable in an aggregated data series, we conclude that this oscillation in mortality was present and was synchronous in most communities in the metapopulation of rural England.
E. its period tended to vary slightly) but had an average period of about 6 years. e. that it was directly driven by an oscillation in the levels of malnutrition. The elite classes would not show this sensitivity to grain prices, but they were of little demographic consequence. The bulk of the population were managing to exist and to reproduce and maintain their population numbers with difficulty on a suboptimal (and doubtless boring) diet. Any annual (or even seasonal) reductions in the availability of grains (their staple food) was reflected demographically in raised levels of mortality (particularly of infants, see Chapter 9).
