Accordingly, more species should coexist in stabler environments. Empirical analyses of trade-offs suggest that, indeed, 'the jack of all trades is master of none'. Diversity represents a balance between speciation and extinction. Theory and experiment suggest that competitive overlap hastens a population's extinction. Currently… CONTINUE READING
