Number of host species as a function of the number of each type of parasite lineage recovered from three areas studied in Tocantins-Brazil.

<p><i>Plasmodium</i> lineages are indicated by no fill symbols and <i>Haemoproteus</i> lineages are indicated by fill symbols. We can observer that one <i>Haemoproteus</i> lineage was presented in 21specimens from 17 different bird species. Genus is not a significant effect in an analysis of covariance (F1,18 = 2.2, P = 0.15). The equation for the line is number of hosts = −0.007 (±0.27 se) +0.77 (±0.04 se) number of infections (F1,19 = 377, P<0.0001, R² = 0.96).
