Viruses with high values of host specificity exhibit plasticity to infect a wide range of hosts, while viruses with lower values are restricted to a few closely related host species Poulin and Mouillot, 2003; Poulin et al., 2011. A Pearson correlation test was performed to explore the relationship between host BD and PBD with changing compositions of viral communities by habitat type calculated by the Sorensen index.
Los virus con valores bajos de especificidad de hospedero muestran una alta plasticidad para infectar a un amplio rango de especies, mientras que los virus con valores altos están restringidos a especies con filogenias emparentadas Poulin y Mouillot, 2003; Poulin et al., 2011.
