“…For example, a decrease in fungal biomass [19] and diversity [20] with increasing altitude were observed in the Austrian Central Alps. A negative correlation between bacterial population and altitude was reported by Ma et al [21] in the cold temperate Kalasi Lake and by Giri et al [22] in a tropical dry deciduous forest. Margesin et al [19] pointed out several shifts in microbial community composition with altitude in the Austrian Central Alps, such as a significant increase in the relative abundance of fungi and Gram-negative (Gm − ) bacteria.…”

Altitudinally-defined climate conditions provide specific vegetation types and soil environments that could influence soil microbial communities, which in turn may affect microbial residues. However, the knowledge is limited in terms of the degree to which microbial communities and residues present and differ along altitude. In this study, we examined the soil microbial communities and residues along the northern slope of Changbai Mountain, China using phospholipid fatty acid (PLFA) and amino sugar analysis, respectively. Soil samples were taken from five different vegetation belts defined by climates. Principal component analysis (PCA) revealed substantial differences in soil microbial community composition among study sites, appeared to be driven primarily by soil pH and C/N ratio on the first principal component (PC1) which accounted for 50.7% of the total sample variance. The alpine tundra was separated from forest sites on the second principal component (PC2) by a signifiscantly higher amount of fungal PLFA (18:2ω6,9). Soil pH and C/N ratio were also correlated with the ratios of Gram-positive to Gram-negative bacteria (Gm+/Gm−), glucosamine to galactosamine (GluN/GalN), and glucosamine to muramic acid (GluN/MurA). Both total PLFAs and amino sugars were positively correlated with soil organic carbon, inorganic nitrogen, available phosphorus and potassium. We concluded that soil pH and C/N ratio were the most important drivers for microbial community structure and amino sugar pattern, while substrate availability was of great importance in determining the concentrations of microbial communities and residues. These findings could be used to facilitate interpretation of soil microbial community and amino sugar data derived from measurements in latitude or managed forests.

“…There are contradictory reports regarding the relation between the methane oxidation rates or methanotrophic population and SOC. Singh et al (1997) found negative correlation between the CH 4 oxidation rate and SOC, while Giri et al (2007) have shown that CH 4 flux in the field was not directly correlated with SOC directly, but was correlated with soil C/N ratio (Tamai et al, 2003).…”

“…Soil organic C (SOC) also affects the methane oxidation capacity of the soil. It may influence the methanotrophic activity by (a) adsorbing the moisture and ensuring its supply during the drought period (Giri et al, 2007), (b) restricting the gaseous diffusion (Kravchenko et al, 2005), and (c) providing methane (through methanogenesis) and other nutrients (Singh et al, 1997;Steinkamp et al, 2001b). Singh et al (1997) suggested that SOC regulates the soil methane uptake capacity in long term.…”

“…The majority of the cultured microorganisms affiliated with uncultured sequences that belonged mainly to the Gamma -, Beta - and Alphaproteobacteria , Actinobacteria and to the CFB group (Lipson and Schmidt 2004). In forest soils, a high microbial metabolic versatility and capability to adapt to climatic changes associated with seasonality was reported (Ma et al 2004; Giri et al 2007; Männistö et al 2007; Rasche et al 2011; Fierer et al 2011; Shen et al 2013). All these investigations agree that altitude per se is not the driving force to promote changes in the microbial structure, instead a wider range of factors, such as the temperature and precipitation regimes that may indirectly control soil carbon input by influencing plant community and primary production, has to be considered.…”

Seasonal and altitudinal changes of culturable bacterial and yeast diversity in Alpine forest soils

et al. 2016

The effect of altitude and season on abundance and diversity of the culturable heterotrophic bacterial and yeast community was examined at four forest sites in the Italian Alps along an altitude gradient (545–2000 m). Independently of altitude, bacteria isolated at 0 °C (psychrophiles) were less numerous than those recovered at 20 °C. In autumn, psychrophilic bacterial population increased with altitude. The 1194 bacterial strains were primarily affiliated with the classes Alpha-, Beta-, Gammaproteobacteria, Spingobacteriia and Flavobacteriia. Fifty-seven of 112 operational taxonomic units represented potential novel species. Strains isolated at 20 °C had a higher diversity and showed similarities in taxa composition and abundance, regardless of altitude or season, while strains isolated at 0 °C showed differences in community composition at lower and higher altitudes. In contrast to bacteria, yeast diversity was season-dependent: site- and altitude-specific effects on yeast diversity were only detected in spring. Isolation temperature affected the relative proportions of yeast genera. Isolations recovered 719 strains, belonging to the classes Dothideomycetes, Saccharomycetes, Tremellomycetes and Mycrobotryomycetes. The presence of few dominant bacterial OTUs and yeast species indicated a resilient microbial population that is not affected by season or altitude. Soil nutrient contents influenced significantly abundance and diversity of culturable bacteria, but not of culturable yeasts.Electronic supplementary materialThe online version of this article (doi:10.1007/s00792-016-0874-2) contains supplementary material, which is available to authorized users.
