Abstract Nitrogen (N) and phosphorus (P) are essential nutrients for plant metabolism, their availability often limits primary productivity. Whereas the effects of N on photosynthetic capacity well established, we still know relatively little about P at a foliar level, especially in P‐limited tropical forests. We examined capacity, leaf mass per area (LMA) fractions five woody species after 6 years fertilization lowland forest. Foliar N:P ratios indicated limitation unfertilized plants;...
Summary Tropical forests represent a major terrestrial store of carbon (C), large proportion which is contained in the soil and decaying organic matter. Woody debris plays key role forest C dynamics because it contains sizeable total C. Understanding factors controlling decomposition matter general, woody particular, hence critical to assessing changes tropical storage. We conducted factorial fertilization experiment South China investigate influence nitrogen (N) phosphorus (P) availability...
Abstract Plant N:P ratios are widely used as indices of nutrient limitation in terrestrial ecosystems, but the response these metrics different plant tissues to altered N and P availability their interactions remains largely unclear. We evaluated changes concentrations, new leaves (<1 yr), older (>1 stems mixed fine roots seven species after 3-years an addition experiment a tropical forest. Nitrogen only increased root concentrations. concentrations among all tissues. The × interaction...
Abstract Due to intensifying human disturbance, over half of the world's tropical forests are reforested or afforested secondary plantations. Understanding resilience carbon (C) stocks in these forests, and estimating extent which they can provide equivalent sequestration stabilization old growth forest replace, is critical for global C balance. In this study, we combined estimates biomass with a detailed assessment soil pools bare land, Eucalyptus plantation, natural old‐growth after 50...
Abstract Precipitation is projected to change intensity and seasonal regime under current global projections. However, little known about how precipitation changes will affect soil respiration, especially in seasonally dry tropical forests. In a forest South China, we conducted manipulation experiment simulate delayed wet season (DW) wetter (WW) over three‐year period. DW, reduced 60% throughfall April May delay the onset of irrigated same amount water into plots October November extend end...
Abstract Leaf soluble sugars and starch are important components of nonstructural carbohydrates (NSCs), which crucial for plant growth, development, reproduction. Although there is a large body research focusing on the regulation NSC (soluble starch) concentrations, response foliar concentrations to continuous nitrogen (N) phosphorus (P) addition still unclear, especially in tropical forests. Here, we used long‐term manipulative field experiment investigate leaf N P (3‐, 5‐, 8‐year...
The arsenic (As) release from litter decomposition of As-hyperaccumulator (Pteris vittata L.) in mine areas poses an ecological risk for metal dispersion into the soil. However, effect atmospheric nitrogen (N) deposition on tailing area remains poorly understood. In this study, we conducted a microcosm experiment to investigate As during P. under four gradients N addition (0, 5, 10, and 20 mg g−1). N10 treatment (10 g−1) enhanced by 1.2–2.6 folds compared control. Furthermore, Streptomyces,...
In the tropics of South China, climate change induced more rainfall events in wet season last decades. Moreover, there will be frequently spring drought future. However, knowledge on how litter decomposition rate would respond to these seasonal precipitation changes is still limited. present study, we conducted a manipulation experiment tropical forest. First, applied 60% exclusion April and May defer onset added same amount water October November mimic deferred (DW); second, increased as...
Intercropping of hyperaccumulators with crops has emerged as a promising method for remediating arsenic (As)-contaminated soil in agroecosystems. However, the response intercropping different types legume plants to diverse gradients As-contaminated remains poorly understood. In this study, we assessed plant growth and accumulation an As hyperaccumulator (Pteris vittata L.) intercropped two three soil. Results indicated that concentration had substantial effect on uptake by plants. P. growing...
Abstract Nitrogen availability and tree species selection play important roles in reforestation. However, long-term field studies on the effects mechanisms of composition N transformation are very limited. Eight years after seedlings were planted a experiment, we revisited site tested how affects dynamics mineralization nitrification. Both season significantly influenced soil dissolved organic carbon (DOC) nitrogen (DON). N-fixing Acacia crassicarpa monoculture had highest DON 10-mixed...
The plasticity of morphological, physiological and developmental traits can reflect the plant adaptation to diverse environmental changes. How foliar morphological with different functional groups in response N P fertilization is still unclear tropical forests. Here, we employed a nine-year manipulative field experiment nitrogen (N) phosphorus (P) addition investigate as well stoichiometry within overstory understory species secondary forest southern China. Our results showed that did not...
Abstract Mineral nutrients play a pivotal role in plant growth, development and reproduction. The uptake distribution of are generally limited by soil nutrient availability, affected global change. However, the responses foliar mineral concentrations to changes availability remain largely untested tropical forests. We used field‐based experiment with nitrogen (N) phosphorus (P) addition forest southern China investigate effect N P fertilization on exchangeable five understorey species. Our...
Soil organic carbon (SOC) is a crucial component of the soil pool that regulates fundamental properties and water status. In global context restoring vegetation, carbon-water coupling relationship has gained attention. particular, regulatory mechanism SOC on moisture requires further research. this study, three typical forests in subtropical China were chosen as restoration sequences to investigate changes during forest its regulation mechanisms: broadleaf-conifer mixed (EF), broad-leaved...
