“…This nding was in agreement with previous ndings from the research also conducted in the Qinghai-Tibetan Plateau, which showed that the dominant archaeal phylum was Thaumarchaeota, accounting for 79.27% of sequences [32]. Thaumarchaeota have been detected in a variety of habitats [48][49][50], and identi ed as a novel archaeal phylum in 2008 [48].…”

“…The Qinghai-Tibetan Plateau (QTP), known as the "roof of the world" and "the third pole", is an important component of the terrestrial ecosystem, which provides many vital ecological services [30]. As one of the world's most vulnerable habitat, the QTP region has harsh environmental conditions and is highly sensitive to environmental disturbance, which could greatly impact the distribution of organisms, especially soil microorganisms [31][32][33]. The knowledge about their underground microorganisms have largely been studied [34][35][36], but the characteristics of rhizosphere microbiota, particularly archaeal communities are inadequate.…”

Background: The Qinghai-Tibetan Plateau represents one of the most important component of the terrestrial ecosystem and a particularly vulnerable region, which harbouring complex and diverse microbiota. The knowledge about their underground microorganisms have largely been studied, but the characteristics of rhizosphere microbiota, particularly archaeal communities remains unclear.Results: High-throughput Illumina sequencing was used to investigate the rhizosphere archaeal communities of two native alpine trees (Picea crassifolia and Populus szechuanica) living on the Qinghai-Tibetan Plateau. The archaeal community structure in rhizospheres significantly differed from that in bulk soil. Thaumarchaeota was the dominant archaeal phylum in all soils tested (92.46-98.01%), while its relative abundance in rhizospheres were significantly higher than that in bulk soil. Ammonium nitrogen, soil organic matter, available phosphorus and pH were significantly correlated with the archaeal community structure, and the deterministic processes dominated the assembly of archaeal communities across all soils. In addition, the network structures of the archaeal community in the rhizosphere were less complex than they were in the bulk soil, and an unclassified archaeal group (Unclassified_k_norank) was identified as the keystone species in all archaeal networks. Conclusions: Overall, the structure, assembly and co-occurrence patterns of archaeal communities are significantly affected by the presence of roots of alpine trees living on the Qinghai-Tibetan Plateau. This study provides new insights into our understanding of archaeal communities in vulnerable ecosystems.

“…Archaeal generalists were overwhelmingly dominated by Nitrososphaeraceae (formerly described as Group 1.1b; Fig. 4), which is consistent with several studies [65,66]. We could further approve the wellknown pH preference of Group 1.1c for acidic forest soils [67].…”

Background: Recent studies have made significant progress in understanding how microbial composition varies across the major terrestrial biomes. However, they neglected large-scale environmental gradients and a defined set of global environmental predictors, which are applicable within biomes and across gradients, are elusive. We identified the soil microbial community composition on a broad continental scale along the Chilean Coastal Cordillera based on the generalist-specialist concept. Thereby, encompassing surface and subsurface soils from arid, semi-arid, mediterranean, and humid-temperate climate conditions.Results: Our results showed that soil communities from different climate regions are composed of the same subset of taxonomic groups. We further identified generalists, comprising taxa that predominated in all four regions, and habitat specialists that predominated in one or two regions only. We obtained higher proportions of habitat specialists (34 groups) than generalists (22 groups) with an increase of the generalist-to-specialist index along our gradient from North to South. The arid climate region revealed a unique hotspot of microbial specialization (60.1%). Contrary, the mediterranean and semi-arid regions featured mainly boundary-crossing specialists (35.5%).Conclusions: Our study supports that species sorting in response to local environmental factors is a key determinant of microbial community composition and further, the degree of microbial specialization can potentially be linked to the overall ecosystem stability.

“…From previous studies, it is clear that soil archaeal communities can vary in predictable ways along broad environmental gradients [10,11,[14][15][16], and between different habitats [17]. Our previous study [8] sampled archaea in both primary forest and agricultural environments on a broad scale across Malaysia, finding that soil pH played a major role in community composition.…”

Distinctive Soil Archaeal Communities in Different Variants of Tropical Equatorial Forest

Little is known of how soil archaeal community composition and diversity differ between local variants of tropical rainforests. We hypothesized that (1) as with plants, animals, fungi, and bacteria, the soil archaeal community would differ between different variants of tropical forest; (2) that spatially rarer forest variants would have a less diverse archaeal community than common ones; (3) that a history of forest disturbance would decrease archaeal alpha- and beta-diversity; and (4) that archaeal distributions within the forest would be governed more by deterministic than stochastic factors. We sampled soil across several different forest types within Brunei, Northwest Borneo. Soil DNA was extracted, and the 16S rRNA gene of archaea was sequenced using Illumina MiSeq. We found that (1) as hypothesized, there are distinct archaeal communities for each forest type, and community composition significantly correlates with soil parameters including pH, organic matter, and available phosphorous. (2) As hypothesized, the "rare" white sand forest variants kerangas and inland heath had lower archaeal diversity. A nestedness analysis showed that archaeal community in inland heath and kerangas was mainly a less diverse subset of that in dipterocarp forests. However, primary dipterocarp forest had the lowest beta-diversity among the other tropical forest types. (3) Also, as predicted, forest disturbance resulted in lower archaeal alpha-diversity-but increased beta-diversity in contrast with our predictions. (4) Contrary to our predictions, the BetaNTI of the various primary forest types indicated community assembly was mainly stochastic. The possible effects of these habitat and disturbance-related effects on N cycling should be investigated.
