title: An example of circular statistics in chronobiological studies: analysis of polymorphism in the emergence rhythms of Schistosoma mansoni cercariae.
abstract: Chronobiological data concerning the emergence rhythms of Schistosoma mansoni cercariae were transformed into circular variables and analysed using circular statistics. The method proposed allowed three chronobiological patterns to be distinguished for the parasite populations studied, and statistical tests for the homogeneity of samples in each group and the significant differences between groups were also carried out.
