Document Summary

Crowding effect facts: when you look at the growth of parasites compared to the total per host, the graph is sort of logarithmic with a point at which the graph tapers off, when you look at a graph of the number of parasites compared with the size, there is a negative sigmoidal sort of relationship. When you have higher numbers of parasites, the size of the parasite decreases: when people realized that there are actually constraints on parasite growth, there was a realization that parasites do not just grow in a way that is not limited, 1960s (cid:224)students of chandler and reid did research on ecological processes that govern the growth of the parasites. Another area of research (cid:224) what mechanisms govern the number of parasites that establish in the host: most parasites accumulate in the host in a negative binomial distribution pattern, 1970s (cid:224)crofton published a paper on the qualitative assessment of parasite distribution.
