Different meal, same flavor: cospeciation and host switching of haemosporidian parasites in some non-passerine birds

Table 1 Cost-event codivergence analysis for the distribution of mtDNA cyt b lineages of haemosporidian parasites across their avian hosts

For each analysis we conducted 100 randomizations to determine whether the predicted number of each event type is higher or lower than expected by chance.
^aEvent costs are for codivergence (cospeciation), duplication (within-host speciation), sorting (extinction), and host switching, respectively.
^bThe number of events significantly exceeds that for randomized trees (P < 0.05).
^cThe number of events is significantly less than that for randomized trees (P < 0.05).
