The book presents a novel theory of bioversity by analyzing the distribution of abundances among species in the context of a community. The basis of this new theory is a distribution called the “J distribution." This distribution is a pure hyperbola and mathematically implied by the “stochastic species hypothesis” assigning equal probabilities of birth and death within the population of each species over varying periods of time. The J distribution in natural communities has strong empirical support resulting from a metastudy and strong theoretical support from a theorem that is mathematically implied by the stochastic species hypothesis.
