Dispersal limitation drives successional pathways in Central Siberian forests under current and intensified fire regimes.
Fire is a primary driver of boreal forest dynamics. Intensifying fire regimes due to climate change may cause a shift in boreal forest composition toward reduced dominance of conifers and greater abundance of deciduous hardwoods, with potential biogeochemical and biophysical feedbacks to regional and global climate. This shift has already been observed in some North American boreal forests and ...
متن کاملNutrient Limitation on Ecosystem Productivity and Processes of Mature and Old-Growth Subtropical Forests in China
Nitrogen (N) is considered the dominant limiting nutrient in temperate regions, while phosphorus (P) limitation frequently occurs in tropical regions, but in subtropical regions nutrient limitation is poorly understood. In this study, we investigated N and P contents and N:P ratios of foliage, forest floors, fine roots and mineral soils, and their relationships with community biomass, litterfal...
متن کاملDifferences in Fine-Root Biomass of Trees and Understory Vegetation among Stand Types in Subtropical Forests
Variation of total fine-root biomass among types of tree stands has previously been attributed to the characteristics of the stand layers. The effects of the understory vegetation on total fine-root biomass are less well studied. We examined the variation of total fine-root biomass in subtropical tree stands at two sites of Datian and Huitong in China. The two sites have similar humid monsoon c...
متن کاملLand cover, more than monthly fire weather, drives fire-size distribution in Southern Québec forests: Implications for fire risk management
Fire activity in North American forests is expected to increase substantially with climate change. This would represent a growing risk to human settlements and industrial infrastructure proximal to forests, and to the forest products industry. We modelled fire size distributions in southern Québec as functions of fire weather and land cover, thus explicitly integrating some of the biotic intera...
متن کاملBiomass and carbon stocks in Schima superba dominated subtropical forests of eastern China
Quantitative relationships between stand indices and carbon dioxide (CO2) stocking are missing in the evergreen broadleaved forests (EBLFs) in eastern China and this hinders to estimate carbon (C) budget in the subtropical region. We determined the vegetation-soil C pool and CO2 stocking using stand indices [diameter at breast height (DBH), total height (H) and wood density] in Schima superba d...
