Litter decomposition plays an important role in the nutrient cycle of terrestrial ecosystems. The alpine wetland has a high litter accumulation rate and slow degradation rate, which is extremely sensitive to changeable freeze–thaw patterns against background global climate change. Freeze-thaw process common natural phenomenon middle-high latitudes altitudes. Hydrothermal changes caused by freezing thawing affect survival physiological characteristics microorganisms, then litters. could be ideal example for altitude study mechanism microbial community structure function during composition process. Moreover, seldom research whole fields. bacterial fungal communities were analyzed three different Carex stages—fresh, four-, six-month—during period using 16/18S rDNA pyrosequencing. Phyllosphere microflora had identified rapid function. Bacteria mainly influenced environmental factors (air temperature, soil moisture), significantly related lignin change C/N ratio. Fungi affected both quality factors, cellulose phyllosphere organisms, including bacteria (Cryobacterium Paracoccus members) fungi (Mrakia, Mrakiella, Naganishia), replaced with specific metabolic capabilities adapt each particular stage. Ilumatobacter genera, Mycosphaerella Athelia characteristic four-month-old samples, whereas Brevundimonas, Nigrospora six-month-old samples. Our results suggest that structures forest initial stages may similar but their differ substantially.

Leaf litter decomposition plays a vital role in the nutrient budget of forest ecosystems.Fungal communities colonising leaf are "key players" and recycling, because their ability to produce wide range extracellular enzymes that facilitate breakdown litter.Fungal colonization decomposing is sequential process during which fungal tend change both quantitatively qualitatively.Most previous studies on succession have taken synecological approaches, recording species assemblages at different stages various plant species.This paper brings together decomposition, including study methods, stages, controlling factors, limitations future perspectives.We discuss high throughput methods as emerging complementary approaches better understand diversity community dynamics.We propose importance current combining morphological molecular data studies.Nevertheless, there still opportunities for further breakthroughs this area few research groups applied these techniques experiments.

Residues of cover crop grasses release nitrogen (N) to subsequent crops, which can contribute sustainable agricultural management and prevent increases in N-loss-related microorganisms. Moreover, applying N fertilizer crops enhance the N-use efficiency yields cash tighten cycle soil. However, long-term effects fertilization on soil microbiota tropical grass-crop no-till systems are unknown. The aim this study was evaluate timing or maize yields, total microbial abundances N-cycle gene at time harvest. We carried out a field experiment with two (palisade grass (Urochloa brizantha) ruzigrass (U. ruziziensis) fertilized 120 kg ha−1 (ammonium sulfate) one three times: (i) broadcast over green 35 days before seeding (35 DBS), (ii) straw residues 1 day (1 (iii) as side-dressing V4 growth stage according conventional method (band-applied 0.05 m from row). A control treatment without application also for both species. Except control, 40 ammonium sulfate subsurface band-applied all treatments 0.05–0.10 row seeding, corresponding 160 ha−1. bacterial, archaeal fungal genes encoding enzymes were quantified by real-time PCR harvest stage. Overall, yield increased significantly applications (average 13 Mg ha−1) compared (6 growing seasons, following palisade having highest yield. archaea fungi under that received DBS, values 4.6 × 106 1.7 107 copies/g dry soil, respectively. Both production positively correlated microbe densities. When crop, low enhanced nifH abundance. Archaeal amoA abundance biomass regardless grass. Bacterial amoA, nirK, nirS not linked mineralization. conclude should be applied using currently recommended (40 side-dressed maize, respectively) achieve high while controlling level loss via nitrification denitrification.
