fire and phosphorus limitation

Climate, fire and soil nutrient limitation are important elements that affect vegetation dynamics in areas of the forest-savanna transition. In this paper, we use the dynamic vegetation model INLAND to evaluate the influence of interannual climate variability, fire and phosphorus (P) limitation on Amazon-Cerrado transitional vegetation structure and dynamics.We assess how each environmental ...


2021-5-6 · A decade after fire, the burned site exhibited an increase in soil nitrogen and phosphorus availability and a transition toward taller, more productive, and more deciduous vegetation. This shift in vegetation structure, composition, and function was induced at the unburned site through the addition of both NP + and the alleviation of their co‐limitation.


2021-6-18 · Red phosphorus fire retardants are safe in daily life as well, given that the amount of phosphine emitted from products containing red phosphorus fire retardants is miniscule, and well below the threshold limit value for the work environment. …


2018-1-4 · The biogeochemical and stoichiometric signature of vegetation fire may influence post-fire ecosystem characteristics and the evolution of plant ‘fire traits’. Phosphorus (P), a potentially limiting nutrient in many fire-prone environments, might be particularly important in this context; however, the effects of fire on P cycling often vary ...


pulses in nitrogen (N) and phosphorus (P) that can increase their availability to plants. Plant growth is frequently limited by N and P, and fire has the potential to enhance or moderate the magnitude of N and P limitation in plants with important con-sequences for long-term net primary productivity and global carbon cycling. We used meta-analysis


We tested this hypothesis with a 2‐yr fertilization experiment. At peak biomass, we found a 30 percent increase in live biomass in plots with N added and no increase in production with only phosphorus (P) added. N and P together were synergistic, suggesting that co‐limitation or P limitation becomes important when N is more available.


In terms of magnitude, the effect of fire is strongest and is the main driver of vegetation changes along the transition. Phosphorus limitation, in turn, has a stronger effect on transitional ecosystem dynamics than interannual climate variability does.


2020-3-24 · Moreover, fire disturbances generally volatilize more N than P and may contribute to N limitation in fire-prone biomes 11,12. Anthropogenic N deposition may increase P limitation in hotspot regions13–17, and elevated atmospheric carbon dioxide (CO


2015-2-20 · Nitrogen (N) and/or phosphorus (P) limitation to primary productivity and other biological processes can change in a variety of ways as ecosystems develop. How N limitation and P limitation change from the early to the late stages of a secondary succession following farmland abandonment remains unclear in karst ecosystems in southwest China. We used community foliar N:P ratio, soil …

2002-8-20 · The interaction of plant and fungal nutrient limitation on the biomass of mycorrhizal fungi. At high nutrient levels, fungi will receive little carbon from plants and will be C-limited. At lower nutrient levels, plants will be N- or phosphorus P-limited and will allocate C to mycorrhizal fungi.


2015-3-6 · Fires are widespread and can result in large nutrient losses from ecosystems simultaneous with pulses in nitrogen (N) and phosphorus (P) that can increase their availability to plants. Plant growth is frequently limited by N and P, and fire has the potential to enhance or moderate the magnitude of N and P limitation in plants with important consequences for long-term net primary productivity ...

2018-10-17 · measure of nutrient limitation (Koerselman and Meuleman 1996;Gu¨sewell 2004). Foliar N:P ratios have been measured over longer times after fire and suggest that ecosystems experience N limitation (Dura´n et al. 2010), P limitation (Seaman et al. 2015), or co-limitation by N and P (Schafer and Mack 2014) across postfire chronosequences. However,


2020-2-10 · Nitrogen (N) and phosphorus (P) limitation constrains the magnitude of terrestrial carbon uptake in response to elevated carbon dioxide and climate change. However, global maps of nutrient ...


2016-3-7 · The literature primarily supports the hypothesis that nutrients may interact dynamically with fire to restrict the transition of savanna into forest. A compilation of indirect metrics of nutrient limitation suggest that nitrogen and phosphorus are both in short supply and may limit plants. Nutrient demand calculations provided a number of insights.


2012-8-3 · Nutrient limitation to net primary production (NPP) displays a diversity of patterns as ecosystems develop over a range of timescales. For example, some ecosystems transition from N limitation on young soils to P limitation on geologically old soils, whereas others appear to remain N limited. Under what conditions should N limitation and P limitation prevail?


2021-2-15 · Nitrogen and phosphorus limit plant growth in most, if not all, terrestrial ecosystems (Vitousek and Howarth 1991).Because fire has the potential to alter the re lative availability of N versus P both immediately following fire and over inter fire cycles, a fundamental question about nutrient limitation is whether fire causes shifts in N versus ...


2004-8-1 · Although P availability is low in these soils and may partially limit biomass growth, the most striking result of this study so far is the significant response of tree growth to N fertilization. Repeated fire and other losses of N from degraded pastures may render tree growth N limited in some young Amazonian forests.


2020-10-10 · Fire can ease P limitation and decouple the biogeochemical cycling of nutrients, potentially causing reversion to an earlier stage of ecosystem development. These effects also depend on vegetation and soil types (Butler et al., 2018). Vegetation is an important participant in the geochemical process of phosphorus cycling.

Phosphorus (P) is a key nutrient involved in the transfer of energy and the synthesis of several cellular components. It has been reported that P limitation in diatoms induces the synthesis of biomolecules and the accumulation of storage compounds, such as pigments, carbohydrates and lipids, with diverse biological activities, which can be used in diverse biotechnological applications.


2004-6-1 · Aleppo pine (Pinus halepensis) and the evergreen holm oak (Quercus ilex) dominate forest areas of the Mediterranean Basin. Both species regenerate abundantly after fires: pine through seedlings and holm oak through resprouts. Cumulative nutrient losses caused by frequent fires may have decreased soil nutrient availability in such areas. To assess the role of nitrogen and phosphorus as …

Phosphorus (P) is a fundamental component of plant organisms. Most of the Earth System Models (ESMs) project increases in future Net Primary Productivity (NPP) due to climate warming. However, large uncertainty exists in projected NPP due to future P limitation. Subtropical China is a region with high vegetation NPP, but its forests are mostly P limited.
