Archaeal communities in dairy cattle manure before and after aging and house fly larval grazing. a) Archaeal OTUs in Fresh, Aged, and house fly larval grazed (Grazed) manure types. Overlapping sections present the number of OTUs shared between and/or across manure types, and non-overlapping are unique to the manure type. Each manure type consisted of 4 replicates except fresh which included 8 replicates; b) Mean relative abundance of archaeal taxon at finest taxonomic resolution across manure types; c) Effect of manure types on the relative abundance of archaeal genera: Methanomassiliicoccus, Methanosphaera, Methanocorpusculum, and Methanobrevibacter. In the box plots, median and interquartile range (25th–75th percentiles; boxes) with upper and lower range of values are shown. The different letters on top of each box indicate the significant differences between manure types (p ≤ 0.05)
