The effect of carbon dioxide fertilization on forest productivity may ultimately be limited by the rate of nutrient cycling. Contemporary and future disturbances such as climatic warming, N-deposition, deforestation, short rotation sylviculture, fire (both wild and controlled), and the invasion of exotic species all place strains on the integrity of ecosystem nutrient cycling. Global differences in climate, soils, and species make it difficult to extrapolate even a single important study worldwide. Despite advances in the understanding of nutrient cycling and carbon production in forests, many questions remain. The chapters in this volume reflect many contemporary research priorities. The thirteen studies in this volume are arranged in the following subject groups: • N and P resorption from foliage worldwide, along chronosequences and along elevation gradients; • Litter production and decomposition; • N and P stoichiometry as affected by N deposition, geographic gradients, species changes, and ecosystem restoration; • Effects of N and P addition on understory biomass, litter, and soil; • Effects of burning on soil nutrients; • Effects of N addition on soil fauna.Biology, life sciencesbicsscForestry industrybicsscResearch and information: generalbicsscAlpine treelinebiomassclimate variablesclimate zonesclimatic factorscommunity structureconversion coefficientCunninghamia lanceolataCyclocarya paliurusdisturbancediversityecological stoichiometryexperimental firesexperimental nitrogen additionfood resourcesforestsgeographic variationsgreen leaf nutrientleaf N:P stoichiometryleaf stoichiometrylitter decompositionlitter standing crop carbonmanagementmixture effectN additionN and P colimitationN:P rationatural forestnatural grasslandnatural populationsnitrogenNitrogennitrogen and phosphorousnitrogen and phosphorus additionnitrogen depositionNon-structural carbohydratesnonstructural carbohydratesnutrient cyclingnutrient limitationsnutrient resorptionnutrientsnutrition resorptionphosphorusPhosphorusplant functional typesplant nutrientplant-soil feedbackplanted forestspoplar plantationsPotassiumprecipitationRemobilizationrhizosphere effectRobinia pseudoacacia L.seasonal variationsshrublandssoil faunasoil N:P stoichiometrysoil nutrientsoil profilesoil propertiessoil stoichiometryspecies competitionstand agestoichiometric ratioStoragethermal infrared thermometerTibetan Plateauunderstory plant growthunderstory plantsUpper limitsUV-spectroscopy analysisBiology, life sciencesForestry industryResearch and information: generalQualls Robert Gedt1322911Qualls Robert GothBOOK9910557498503321Nutrient Cycling in Forest Ecosystems3035255UNINA
