    Structure of the Microbial Communities in Coniferous Forest Soils in Relation to Site Fertility and Stand Development Stage T. Pennanen,l J. Liski,2 E. Bdath,3 V. Kitunen,l J. Uotila,4 C.J. Westman,2 H. Fritze' 1 Finnish Forest Research Institute, Post Office Box . The genus Bradyrhizobium has served as a model system for studying host–microbe symbiotic interactions and nitrogen fixation due to its importance in agricultural productivity and global nitrogen cycling. In this study, we identify a bacterial group affiliated with this genus that dominates the microbial communities of coniferous forest soils from six distinct ecozones .

    Understanding the ecology of coniferous forests is very important because these environments represent globally largest carbon sinks. Metatranscriptomics, microbial community and enzyme analyses were combined to describe the detailed role of microbial taxa in the functioning of thePicea abies-dominated coniferous forest soil in two contrasting. Metatranscriptomics combined with microbial community analysis was used to describe the roles of individual microbial taxa in the coniferous forest soil in two contrasting seasons. Both the microbial community composition and the pool of microbial transcripts were found to be highly diverse and subject to seasonal changes, especially in soil.

Humus phospholipid fatty acid (PLFA) analysis was used in clear-cut, wood-ash fertilized (amounts applied:, and kg ha −1), or prescribed burned (both in standing and clear-cut) coniferous forests to study the effects of treatments on microbial biomass and community microbial biomass (total PLFAs) decreased significantly due to the Cited by:   5oi7 Biol.

A comparative microbial population analysis showed that coniferous forest soils contained lower numbers of bacteria, fusaria, facultative anaerobes, and putative nitrogen-fixing bacteria than nursery soils, while the populations of actinomycetes, extracellular chitinase producers, fluorescent pseudomonads, and phosphate solubilizers did not differ.

An understanding of this ecological continuum is of great significance for drawing inferences about the effects of community assembly processes on microbial community structure and function.

Here, we investigated the driving forces of soil microbial. forest ecosystems, particularly of coniferous forests and other nutrient-poor types.

Nutrient release from fresh plant litter occurs via the enzymatic activities of the microbial communities. The varying predominance of the individual enzymes can be related to the amount of soil microorganisms. To our knowledge, no studies have specifically addressed the effect of charcoal on ammonia‐oxidizing bacteria (AOB) in forest soils.

Controlled experiments have shown that charcoal amendment of fire‐excluded temperate and boreal coniferous forest soil increases net nitrification, suggesting that charcoal plays a major role in maintaining.

The occurrence of mycobacteria was studied in organic horizons of coniferous forest soils in Finland and related to environmental variables, i.e. plate counts of other heterotrophic bacteria, microbial respiration rate, chemical soil characteristics, vegetational characteristics and climatic conditions in the study period.

Soil microbial communities play critical roles as integral components of forest ecosystem processes Vegetation type is a major factor in structuring communities of soil organisms among landscapes 3, Plant species have profound influences on soil microbial communities, especially when comparing coniferous and broadleaved spec23,   Soil bacteria may be influenced by vegetation and play important roles in global carbon efflux and nutrient cycling under global changes.

Coniferous and broadleaved forests are two phyletically. Fire is the predominant natural disturbance that influences the community structure as well as ecosystem function in forests. This study was conducted to examine the soil properties, loss of aboveground biomass, and understory plant community in response to an anthropogenic fire in a coniferous (Pinus massoniana Lamb.) and broadleaf (Quercus acutissima Carruth.) mixed forest.

Understanding the ecology of coniferous forests is very important because these environments represent globally largest carbon sinks. Metatranscriptomics, microbial community and enzyme analyses were combined to describe the detailed role of microbial taxa in the functioning of the Picea abies‐dominated coniferous forest soil in two contrasting seasons.

The bacterial community of forest soils is influenced by environmental disturbance and/or meteorological temperature and precipitation. In this study, we investigated three bacterial communities in soils of a natural hardwood forest and two plantations of conifer, Calocedrus formosana and Cryptomeria japonica, in a perhumid, low mountain area.

Windstorms can often decrease the diversity of native local biota in European forests. The effects of windstorms on the species richness of flora and fauna in coniferous forests of natural reserves are well established, but the effects on biotas in productive deciduous forests have been less well studied.

We analyzed the impact of windstorms on the diversity and abundance of soil. We studied the effect of tree species and fertilization on the forest floor microbial community of year-old regenerating forests.

We sampled F and H forest floor layers of plots planted to Thuja plicata (Donn ex D. Don.) or Tsuga heterophylla (Raf.) Sarg.

on N-poor and N-rich sites, with and without fertilizer treatments. Nitrogen in Soil Water of Coniferous Forests, Effects of Anthropogenic Disturbances Abstract In boreal and temperate forests, long-term elevated nitrogen (N) load may eventually saturate forest ecosystems with N, i.e. total N ecosystem input exceed ecosystem sinks for N, and N losses via soil water transport may then increase and negatively impact.

Microbial Diversity in Soils The 16S and 18S rRNA-encoding genes contain regions of strict sequence con-servation that are valuable for the design of universal primers to amplify the genes via PCR.

These conserved regions are interspersed with regions of sequence vari-ability that are useful for comparative analysis.The soils of these regions are generally fragile and vulnerable due to climatic aridity; their degradation today has accentuated the phenomenon of objective of this work was to compare the physicochemical and microbiological characteristics of the coniferous forest soils of the semi-arid and arid zones of the Algerian west.Coniferous forest, vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in areas with long winters and moderate to high annual precipitation.

Pines, spruces, firs, and larches are the dominant trees in coniferous forests with a layer of low shrubs or herbs beneath.
