Understanding how biotic interactions and environmental filtering mediated by soil properties shape plant community assembly is a major challenge in ecology, especially when studying complex hyperdiverse ecosystems like tropical forests. To shed light on the influence of both factors, we examined edaphic optimum species (their niche position) related to their range breadth) along different gradients this translates into functional strategies. Here tested four scenarios describing breadth-niche position relationship, including one neutral scenario three proposing relative influences abiotic factors resource gradient. do so, used concentration data for five key nutrients (N, P, Ca, Mg, K), with accurate measurements 14 leaf, stem, root traits 246 tree inventoried 101 plots located across Eastern (French Guiana) Western (Peru) Amazonia. We found that breadth increased linearly each nutrient This increase was associated more acquisitive leaves roots N, K concentration, while it negatively wood density P concentration. These observations agreed our hypothetical which conservation are confined most nutrient-depleted soils (abiotic filter), but they outperformed faster-growing fertile conditions (biotic filter). Our results refine strengthen support theories providing an integrated approach improving forest management policies.

Abstract The term carbon (C) sequestration has not just become a buzzword but is something of siren's call to scientific communicators and media outlets. Carbon the removal C from atmosphere storage, for example, in soil. It potential partially compensate anthropogenic greenhouse gas emissions is, therefore, an important piece global climate change mitigation puzzle. However, often used misleadingly and, while likely unintentional, can lead perpetuation biased conclusions exaggerated expectations about its contribution efforts. Soils have considerable take up many are also state continuous loss. In such soils, measures build soil may only reduction losses (C loss mitigation) rather than result real negative emissions. examination 100 recent peer‐reviewed papers on topics surrounding C, 4% were found correctly. Furthermore, 13% equated with stocks. review, further, revealed that leading will always when non‐CO 2 gases leakage taken into consideration. This paper highlights pitfalls using incorrectly calls accurate usage this going forward.

Abstract The capacity for terrestrial ecosystems to sequester additional carbon (C) with rising CO 2 concentrations depends on soil nutrient availability 1,2 . Previous evidence suggested that mature forests growing phosphorus (P)-deprived soils had limited extra biomass under elevated (refs. 3–6 ), but uncertainty about ecosystem P cycling and its response represents a crucial bottleneck mechanistic prediction of the land C sink climate change 7 Here, by compiling first comprehensive budget P-limited forest exposed , we show high likelihood captured microorganisms constrains recycling plant uptake. Trees used efficiently, microbial pre-emption mineralized seemed limit trees increased uptake assimilation and, therefore, their C. Plant strategies stimulate uptake, such as increasing rhizosphere release soil, will probably be necessary increase capture into new biomass. Our results identify key mechanisms which limits fertilization tree growth guide development Earth system models predict future long-term storage.

Phosphorus deposition can stimulate both plant carbon inputs and microbial outputs. However, how P enrichment affects soil organic (SOC) storage the underlying mechanisms remain unclear. We conducted a meta-analysis of 642 SOC observations from 213 field addition experiments world-wide explored regulations inputs, outputs, characteristics, environmental experimental factors on responses. found that, globally, stimulated by 4.0% (95% CI: 2.0-6.0%), but stimulation only occurred in forest cropland rather than grassland. Across sites, response correlated with that aboveground belowground biomass, suggesting change was more important regulating changes due to addition. Among multiple factors, N fixation status mean annual temperature were best predictors for responses addition, being higher ecosystems dominated symbiotic nitrogen fixers high-temperature regions like tropical forests. Our findings highlight differential ecosystem-dependent contribute accurate predictions dynamics P-enriched world.

Microorganisms play crucial roles in phosphorus (P) turnover and P bioavailability increases heavy metal-contaminated soils. However, microbially driven P-cycling processes mechanisms of their resistance to metal contaminants remain poorly understood. Here, we examined the possible survival strategies microorganisms horizontal vertical soil samples from world's largest antimony (Sb) mining site, which is located Xikuangshan, China. We found that total Sb pH were primary factors affecting bacterial community diversity, structure traits. Bacteria with gcd gene, encoding an enzyme responsible for gluconic acid production, largely correlated inorganic phosphate (Pi) solubilization significantly enhanced bioavailability. Among 106 nearly complete metagenome-assembled genomes (MAGs) recovered, 60.4% carried gene.

Limiting global warming to 2 °C requires urgent action on land-based mitigation. This study evaluates the biogeochemical and biogeophysical implications of two alternative mitigation scenarios that aim achieve same radiative forcing. One scenario is primarily driven by bioenergy expansion (SSP226Lu-BIOCROP), while other involves re/afforestation (SSP126Lu-REFOREST). We find overall, SSP126Lu-REFOREST a more efficient strategy for removing CO from atmosphere 2100, resulting in net carbon sink 242 ~ 483 PgC with smaller uncertainties compared SSP226Lu-BIOCROP, which exhibits wider range −78 621 PgC. However, leads relatively warmer planetary climate than this relative can be intensified certain re/afforested regions where local climates are not favorable tree growth. Despite cooling effect scale, SSP226Lu-BIOCROP reshuffles regional hotspots, amplifying summer temperatures vulnerable tropical such as Central Africa Southeast Asia. Our findings highlight need strategic land use planning identify suitable expansion, thereby improving likelihood achieving intended outcomes.

The Amazon is the largest drainage basin on Earth and contains a wide variety of abiotic landscape features. In spite this, geodiversity in this has not yet been objectively evaluated. We address knowledge gap by combining meta-analysis an existing global map its components with systematic literature review, to identify key characteristics (ADB). also evaluate how these component maps, that are based geology, geomorphology, soils hydrology, could be refined better reflect basin. Our review shows geology—through lithological diversity geological structures—and hydrology—through hydrological processes influence geomorphology soil diversity—are main determinants geodiversity. Based features, ADB can subdivided into three principal regions: (i) Andean orogenic belt western Amazon, (ii) cratons eastern (iii) Solimões-Amazon river system. Additional methods geomorphological have identified. Future research should focus investigating relationship between assess their biodiversity. Such enhance conservation plans for ADB.
