Dimensions of tree root systems in savannas are poorly understood, despite being essential resource acquisition and post-disturbance recovery. We studied rooting patterns Southern African to ask: how strategies affected species responses severe drought; potential depths varied across gradients soil texture rainfall. First, detailed excavations eight Kruger National Park suggest that the ratio deep shallow taproot diameters provides a reasonable proxy for depth, facilitating extensive...
While there is an extensive body of research on the influence climate warming total soil microbial communities, our understanding how rhizosphere and non-rhizosphere microorganisms respond to remains limited. To address this knowledge gap, we investigated impact 4 years diversity composition communities in a temperate steppe, focusing changes root exudation rates exudate compositions. We used open top chambers simulate conditions, resulting average temperature increase 1.1°C over span years....
Fresh plant litter inputs accelerate soil organic matter (SOM) decomposition through a ubiquitous mechanism called priming. Insufficient priming has been suggested as stabilization of SOM at depth, well the long‐term persistence some highly degradable compounds in soils. Priming therefore plays crucial, albeit unquantified and commonly neglected, role global carbon cycle. Because intensity is likely to be altered by change‐induced changes net primary productivity, it casts substantial...
Plant functional traits provide a valuable tool to improve our understanding of ecological processes at range scales. Previous handbooks on plant have highlighted the importance standardising measurements and evolutionary processes. In open ecosystems (i.e. grasslands, savannas, woodlands shrublands), related disturbance (e.g. herbivory, drought, fire) play central role in explaining species performance distributions are focus this handbook. We brief descriptions 34 list important...
Rapid urbanization has exacerbated land use transformation, which in turn affected ecosystem service value (ESV). Clarifying the spatial association between change (LUC) and ESV is of relevance to development policies for sustainable (ES) management. In this paper, taking Hubei Province as an example, biomass coefficient, resource scarcity coefficient socioeconomic adjustment are introduced improve assessment model, then spatiotemporal dynamics from 2000 2020 analyzed. Furthermore, coupling...
Abstract An accurate quantification of global methane sources and sinks is imperative for assessing realistic pathways to mitigate climate change. A key challenge quantifying the Global Methane Budget (Saunois et al., 2020, https://doi.org/10.5194/essd‐12‐1561‐2020 ) lack consistency in uncertainties between sectors. Here we provide a new perspective on bottom‐up (BU) top‐down (TD) by using an expert opinion analysis based questionnaire conducted 2021. Expectedly, experts rank highest...
Abstract As part of the REgional Carbon Cycle Assessment and Processes Phase 2 (RECCAP2) project, we developed a comprehensive African Greenhouse gases (GHG) budget covering 2000 to 2019 (RECCAP1 RECCAP2 time periods), assessed uncertainties trends over time. We compared bottom‐up process‐based models, data‐driven remotely sensed products, national GHG inventories with top‐down atmospheric inversions, accounting also for lateral fluxes. incorporated emission estimates derived from novel...
Summary Recent global trends of increasing woody plant abundance in grass‐dominated ecosystems may substantially enhance soil organic carbon ( SOC ) storage and could represent a strong (C) sink the terrestrial environment. However, few studies have quantitatively addressed influence spatial heterogeneity vegetation properties on at landscape scale. In addition, most assessing response to encroachment consider only surface soils, not explicitly assessed extent which deeper portions profile...
The geographically extensive phenomenon of woody plant encroachment into grass-dominated ecosystems has strong potential to influence biogeochemical cycles at ecosystem global scales. Previous research focused almost exclusively on quantifying pool sizes and flux rates soil carbon nitrogen (N), while few studies have examined the impact phosphorus (P) cycling. Moreover, little is known regarding depth distribution total P landscape scale. We quantified patterns spatial heterogeneity in along...
Abstract Plant essential macronutrients like nitrogen (N) and phosphorus (P) can limit savanna tree growth are important determinants of vegetation dynamics, along with rainfall, fire herbivory. How shape tree‐grass competition their coexistence remain unclear, hindering our ability to predict how savannas may respond altered nutrient cycling. Here, we evaluate (1) if trees grasses differently N versus P availability, or (2) more competitive in low environments while high environments. To do...
Abstract Savanna trees experience various ecological pressures, requiring their roots to serve multiple functions. However, savanna root trait studies have focused on easily measurable traits, emphasizing a single axis of function: resource acquisition in competition with grasses, resilience episodic droughts or storage for recovery following fire herbivory. This narrow focus limits understanding trait–function relationships and factors driving variation. Our synthesis evaluates few key...
Recent urbanization and growing food consumption have had a severely detrimental effect on the ecological environment of Jianghan Plain. The fragility Plain must be continually monitored for environmental conservation sustainable development. This study utilized principal component analysis (PCA) to quantitatively assess vulnerability based remote sensing index (RSEI) analyzed space-time changes drivers in from 2000 2020 using Google Earth Engine Platform (GEE). findings this research...
Abstract Soil carbon, nitrogen, and phosphorus cycles are strongly interlinked controlled through biological processes, the cycle is further geochemical processes. In dryland ecosystems, woody encroachment often modifies soil stores, although it remains unknown if these three elements change proportionally in response to this vegetation change. We evaluated proportional changes spatial patterns of organic carbon ( SOC ), total nitrogen TN TP ) concentrations following by taking spatially...
