Relationships between bacterial lineage diversity (means ± SE of Fisher alpha) and rodent species richness.

Relationships are quantified at different scales and for different organization levels. A- in individual hosts, B- at the plot scale in a population of hosts, C- at the plot scale in a community of hosts, D- at the regional scale in a population of hosts, E- at the regional scale in a community of hosts. The relationships between bacterial diversity and host diversity in individual hosts and host populations are illustrated separately for each host species (Gerbillus andersoni is indicated in green, G. pyramidum in purple and G. gerbillus in red).
