Long-Term Effects of Periodical Fires on Archaeal Communities from Brazilian Cerrado Soils

Figure 5

Phylogenetic tree of archaeal amoA gene OTUs (97% gene sequence similarity) obtained from typical Cerrado sensu stricto soils. The number of sequences represented by each OTU is shown in parentheses, with those from the Control area (C) indicated by blue squares and from the Burned area (Q) by red circles. The tree was constructed using FastTree v. 2.1 [54], with 1000 bootstrap tests. Values below 70% are not shown.
