“…Instead, we can conclude that differences in soil environmental conditions, namely differences in mean annual temperature seem to have important predictable effects on the composition of AOB communities in the soils included in this study. This result is consistent with other studies in soil and aquatic environments where a strong temperature influence on AOB community composition has also been observed [13,18,45,46].…”

Although ammonia-oxidizing bacteria (AOB) are likely to play a key role in the soil nitrogen cycle, we have only a limited understanding of how the diversity and composition of soil AOB communities change across ecosystem types. We examined 23 soils collected from across North America and used sequence-based analyses to compare the AOB communities in each of the distinct soils. Using 97% 16S rRNA sequence similarity groups, we identified only 24 unique AOB phylotypes across all of the soils sampled. The majority of the sequences collected were in the Nitrosospira lineages (representing 80% of all the sequences collected), and AOB belonging to Nitrosospira cluster 3 were particularly common in our clone libraries and ubiquitous across the soil types. Community composition was highly variable across the collected soils, and similar ecosystem types did not always harbor similar AOB communities. We did not find any significant correlations between AOB community composition and measures of N availability. From the suite of environmental variables measured, we found the strongest correlation between temperature and AOB community composition; soils exposed to similar mean annual temperatures tended to have similar AOB communities. This finding is consistent with previous studies and suggests that temperature selects for specific AOB lineages. Given that distinct AOB taxa are likely to have unique functional attributes, the biogeographical patterns exhibited by soil AOB may be directly relevant to understanding soil nitrogen dynamics under changing environmental conditions.

“…Decreasing soil temperature was correlated with increasing AOA abundance, which is in contrast to the results of a soil microcosm study by Tourna et al (2008). However, Urakawa et al (2008) and Caffrey et al (2007) investigated marine ecosystems in which decreased phylogenetic diversity and abundance of AOA were found with increasing temperature, respectively. Based on these contradictory results, we suggest further experiments under field conditions to substantiate that decreasing soil temperature promotes AOA abundance.…”

Seasonality and resource availability control bacterial and archaeal communities in soils of a temperate beech forest

et al. 2010

It was hypothesized that seasonality and resource availability altered through tree girdling were major determinants of the phylogenetic composition of the archaeal and bacterial community in a temperate beech forest soil. During a 2-year field experiment, involving girdling of beech trees to intercept the transfer of easily available carbon (C) from the canopy to roots, members of the dominant phylogenetic microbial phyla residing in top soils under girdled versus untreated control trees were monitored at bimonthly intervals through 16S rRNA gene-based terminal restriction fragment length polymorphism profiling and quantitative PCR analysis. Effects on nitrifying and denitrifying groups were assessed by measuring the abundances of nirS and nosZ genes as well as bacterial and archaeal amoA genes. Seasonal dynamics displayed by key phylogenetic and nitrogen (N) cycling functional groups were found to be tightly coupled with seasonal alterations in labile C and N pools as well as with variation in soil temperature and soil moisture. In particular, archaea and acidobacteria were highly responsive to soil nutritional and soil climatic changes associated with seasonality, indicating their high metabolic versatility and capability to adapt to environmental changes. For these phyla, significant interrelations with soil chemical and microbial process data were found suggesting their potential, but poorly described contribution to nitrification or denitrification in temperate forest soils. In conclusion, our extensive approach allowed us to get novel insights into effects of seasonality and resource availability on the microbial community, in particular on hitherto poorly studied bacterial phyla and functional groups.

“…Comprehensive studies have indicated AOA seemingly played a more important role than AOB in the global N cycling. It has been found that AOA widely occurred in freshwater and marine habitats (Caffrey et al, 2007;Francis et al, 2005;Herrmann et al, 2008), various soils and sediments (Di et al, 2009;He et al, 2007;Long et al, 2012;Sahan and Muyzer, 2008), as well as man-made environments (De Vet et al, 2009;Urakawa et al, 2008;Zhang et al, 2011). Evidence from 12 pristine and agricultural soils in three climatic zones suggested that AOA is the dominant ammonia oxidizer in soils (Leininger et al, 2006).…”

• We examined how fires affected the abundances and communities of soil AOB and AOA.• A long-term repeated forest fire experiment was investigated.• Fires increased the abundance of bacterium amoA genes, but not archaeal amoA genes.• Fire also modified the composition of AOA and AOB communities.• AOB genotype was affected by soil pH and DOC, while AOA by nitrate-N and DOC. a b s t r a c t a r t i c l e i n f o Fire shapes global biome distribution and promotes the terrestrial biogeochemical cycles. Ammonia-oxidizing bacteria (AOB) and archaea (AOA) play a vital role in the biogeochemical cycling of nitrogen (N). However, behaviors of AOB and AOA under long-term prescribed burning remain unclear. This study was to examine how fire affected the abundances and communities of soil AOB and AOA. A long-term repeated forest fire experiment with three burning treatments (never burnt, B0; biennially burnt, B2; and quadrennially burnt, B4) was used in this study. The abundances and community structure of soil AOB and AOA were determined using quantitative PCR, restriction fragment length polymorphism and clone library. More frequent fires (B2) increased the abundance of bacterium amoA gene, but tended to decrease archaeal amoA genes. Fire also modified the composition of AOA and AOB communities. Canonical correspondence analysis showed soil pH and dissolved organic C (DOC) strongly affected AOB genotypes, while nitrate-N and DOC shaped the AOA distribution. The increased abundance of bacterium amoA gene by fires may imply an important role of AOB in nitrification in fire-affected soils. The fire-induced shift in the community composition of AOB and AOA demonstrates that fire can disturb nutrient cycles.
