Litter decomposition is a key driver of ecosystem processes and carbon cycling. Decomposition rate influenced by numerous factors, such as temperature, humidity, litter properties, soil properties fauna/microbial communities. The aim this review was to summarize current knowledge on above the treeline in alpine regions worldwide identify: I) factors that have been studied great detail, II) less intensively investigated, III) geographical well studied, IV) with consistent or inconsistent effects decomposition. showed results for all covered two more studies regarding their effect (positive, negative, no effect), usually result interactions between factors. Studies examining one several physical environment (i.e., altitude, experimental warming, microclimate, snow cover moisture) were most common, while different aspects resource quality second common. impacts trophic microbes fauna frequently studied.

Abstract Treelines advance due to climate warming. The impacts of this vegetation shift on plant–soil nutrient cycling are still uncertain, yet highly relevant as availability stimulates tree growth. Here, we investigated nitrogen (N) and phosphorus (P) in plant soil pools along two tundra–forest transects Kola Peninsula, Russia, with a documented elevation birch‐dominated treeline by 70 m during the last 50 years. Results show that although total N P stocks soil–plant system did not change elevation, their distribution was significantly altered. With transition from high‐elevation tundra low‐elevation forest, stones decreased, possibly reflecting enhanced weathering. In contrast, biomass approximately tripled available increased fivefold toward forest. This paralleled decreasing carbon (C)‐to‐nutrient ratios foliage litter, smaller C:N:P microbial biomass, lower enzymatic activities related acquisition forest soils. An incubation experiment further demonstrated manifold higher net mineralization rates litter compared tundra, likely decomposing organic matter. Overall, our results expansion increases mobilization nutrients through weathering positive feedback, nutrient‐rich releasing greater amounts upon decomposition. While low may retard advances, its improvement promotes growth development.

Coastal nutrient loading has been linked to a decline in the capacity of seagrass ecosystems sequester carbon ('blue carbon'); however, mechanisms are unclear. Here we investigated how can affect contribution that plant material makes blue stocks by investigating quality-decomposition dynamics. Specifically, used combination laboratory and field experiments account for various changes biogeochemical cycling from meadows, ranging leaf quality CO2 fluxes. It was found increased 'labile' content (i.e. levels nitrogen, phosphorus soluble organic (amino acid sugar content), at same time decreased 'recalcitrant' materials harder microbes break down, such hemicellulose, cellulose lignin contents). Nutrient-enriched leaves decomposed ∼ 18 % faster than non-enriched greater biomass loss nutrient-affected seagrass), resulting 80 more emissions nutrient-enriched seagrass. We also naturally contained high labile start experiment were affected degree higher emissions) nutrients addition had proportions recalcitrant begin with. Overall, these findings suggest weaken act as sinks through its effect on decomposability.

Abstract The chemical traits of litter are among the most critical factors that affect its decomposition. During vegetation restoration planted forests, increasing age species and succession understory may lead to significant changes in traits. However, it is unclear how these occur they Therefore, we studied decomposition from four Robinia pseudoacacia plantations Loess Plateau China with stand ages 10–43 years using an indoor simulation test. We measured substrate quality diversity, structural properties microbial community, activity enzymes, mixed effects during restoration. Their relationships rate were analyzed equation modeling. Improvements forest induced by drove fungal community composition late (day 358), which turn increased lignin‐decomposing enzymes ultimately accelerated At same time, decreases diversity reduced fungi middle (days 182 358). This caused negative effects, thereby inhibiting improvements dominated rate, R. plantation thus over course

The internal correlation of plant, litter and soil stoichiometric characteristics their responses to the environment are helpful for revealing nutrient cycling mechanisms. However, few studies have assessed relationship between stock along elevational gradients, which limit understanding relationships in ecosystem. To gain insight into forces its ecological gradients forest ecosystem, we investigated carbon (C), nitrogen (N) phosphorus (P) contents ratios dominant plants, layers at different elevations (900–1600 m) Daiyun Mountain. results showed following: (1) C, N P an increasing order as plant > each elevation Dominant plants were limited by elevation. high higher than those low significant correlations found TN, TP air temperature (negative), conforms Temperature-Plant Physiological Hypothesis (TPPH). (2) Significant C:N (positive); C:P N:P (negative). (3) Elevation slope essential environmental factors ratio litter, pH was main factor that correlated negatively stoichiometry ratio. Litter provided a link soil, there coupling among nutrients. could provide theoretical basis subtropical ecosystem China.
