Key findings from Harvard Forest warming
In 14 control and 14 heated direct samples from organic soil, Acidobacteria relative abundance decreased from 0.035 in control samples to 0.024 in heated samples. 1
This change corresponded to a log2 fold change of −0.549 and an FDR-adjusted q-value of 0.049. 1
The Acidobacteria depletion was part of the reproduced community-level response to a 25-year +5°C soil-warming experiment at Harvard Forest, alongside an increase in actinobacteria. 1
No phylum-level changes remained after FDR correction in mineral soil, so the reported Acidobacteria depletion was specific to the warmed organic-soil comparison in this analysis. 1
Functional-gene evidence from the lanthanide methylotrophy atlas
Using GTDB-r214 taxonomy, the atlas reports Acidobacteriota as carrying 285 xoxF genomes and 3 mxaF genomes among 1,006 genomes; xoxF occurred at a 28.3 % rate with a 95 : 1 xoxF:mxaF ratio and p_BH = 1.2 × 10⁻⁷⁹. 2
This refines the abundance-based warming result by showing substantial representation of the xoxF marker in Acidobacteriota, while annotation alone does not establish methanol-oxidation activity or methylotrophic physiology. 2
Within Acidobacteriota, soil/sediment xoxF enrichment remained significant relative to the reference, with OR = 2.16 and p_BH = 2.2 × 10⁻⁵; this supports a connection between environmental context and functional-gene distribution beyond phylogenetic composition alone. 2

The result links Acidobacteria abundance to horizon-specific environmental responses and functional-gene content in ecotype-environment-gene-content. 1
It also provides an organic-versus-mineral soil case for environment-embedding-geography. 1
The atlas additionally contributes cross-genome functional-marker evidence to pangenome-integration and environmental-distribution evidence to environment-embedding-geography. 2
