Effects of chlamydial infection on an almost completely censused population of koalas at Inverness, Queensland. The number of new recruits in the subsequent year, as a proportion of the number of adults in the current year, is inversely related to the prevalence of cystitis owing to chlamydial infection in the current year (quasi-binomial model, t = −2.23, p = 0.05, d.f. = 9), but there is no evidence that the finite population growth rate ln(N_t+1/N_t) is related to the prevalence of cystitis at time t (linear model r = −0.133, p = 0.27, d.f. = 9).
