The use of disc diffusion susceptibility tests to determine the antibacterial activity engineered nanoparticles (ENPs) is questionable because their low diffusivity practically prevents them from penetrating through culture media. In this study, we investigate ability such a test, namely Kirby-Bauer antimicrobial Au and Ag ENPs having diameters 10 40 nm on Escherichia coli cultures. As anticipated, did not show any effects (NPs) as result negligible NPs other hand exhibited strong that was...
Abstract Enhanced CO 2 assimilation by forests as atmospheric concentration rises could slow the rate of increase if assimilated carbon is allocated to long-lived biomass. Experiments in young tree plantations support a fertilization effect continues increase. Uncertainty exists, however, whether older, more mature retain capacity respond elevated 2. Here, aided tree-ring analysis and canopy laser scanning, we show that 180-year-old Quercus robur L. woodland central England increased...
In the future, with elevated atmospheric CO2 (eCO2), forests are expected to increase woody biomass capture more carbon (C), though this is dependent on soil nutrient availability. While young may access unused nutrients by growing into an unexplored environment, it unclear how or if mature can adapt belowground under eCO2. Soil respiration (Rs) and bioavailability integrative ecosystem measures of below-ground dynamics. At Birmingham's Institute Forest Research Free Air Enrichment (BIFoR...
Abstract. The role of plants in sequestering carbon is a critical component mitigating climate change. A key aspect this involves plant nitrogen (N) uptake (Nup) and N use efficiency (NUE), as these factors directly influence the capacity to store carbon. However, contribution deposition soil (biotic abiotic) addition cycle, remains inadequately understood, introducing significant uncertainties into change projections. Here, we used ground-based observations across 159 locations calculate...
Tree roots adapt their morphological, physiological and biochemical functional traits to optimise nutrient acquisition, notably in response global changes. Therefore, it is hypothesized that, increase acquisition under elevated CO2 (eCO2) sustain productivity, trees will allocate more carbon assimilates into root systems. As fine are thought represent ~1/3 of NPP, understanding how much the additional (C) introduced forest ecosystem by increased photosynthesis allocated belowground, improve...
Abstract The ecosystem services provided by forests modulate runoff generation processes, nutrient cycling and water energy exchange between soils, vegetation atmosphere. Increasing atmospheric CO 2 affects many linked aspects of forest catchment function in ways we do not adequately understand. Global levels will be around 40% higher 2050 than current levels, yet estimates how solute fluxes forested catchments respond to increased are highly uncertain. Free Air Enrichment (FACE) facility...
Increasing CO2 levels are a major global challenge, and the potential mitigation of anthropogenic emissions by natural carbon sinks remains poorly understood. The uptake elevated (eCO2) terrestrial biosphere, subsequent sequestration as biomass in ecosystems, remain hard to quantify ecosystems. Here, we combine field observations fine root stocks flows, derived from belowground imaging soil cores, with image analysis, stochastic modelling, statistical inference, elucidate dynamics mature...
Abstract Intact peatlands provide hydrological ecosystem services, such as regulating water regimes and immobilizing pollutants within catchments. Climate change impacts including drought wildfire may impair their functioning, potentially impacting service delivery. Here we investigate stream quality changes following the combined of a summer in peat‐dominated catchment UK during 2018. The study stores legacy (i.e., metals) due to past industrial activity, thus making it particularly...

Evidence supporting a carbon fertilisation effect, where increasing levels of dioxide (CO2) in the atmosphere lead to photosynthetic enhancement trees, suggests that forests can sequester more under elevated CO2 (eCO2). However, it remains largely unclear and for how long this is stored within forest ecosystem. To sustain eCO2 concentrations, trees are likely require higher intake nutrients from soil, which should stimulate root growth. This ongoing study (2022-2026) investigates hypothesis...
Enhanced productivity of forest ecosystems in response to rising levels anthropogenically generated atmospheric carbon dioxide (CO2) has the potential mitigate against climate change by sequestering woody biomass and soils. However, physiological trees elevated CO2 may be constrained availability soil nutrients, predominantly nitrogen phosphorus (P). Here, we assess impact on P cycling a temperate 180-year-old oak (Quercus robur L.) exposed free-air enrichment (ambient + 150 ppm) for six...
Urbanisation inevitably alters the chemical, physical and biological soil properties. Consequently, it modifies environmental services. The sealing of – covering surface with non-biological structures - has gained attention in urban area relation to flooding, loss carbon, function other problems, which can be mitigated introducing greenspaces areas. To understand impact on properties, beneath three pavement types (concrete, slab tarmac) from paired unsealed areas (representing four...
Over half of the world’s population live currently in urban areas with future projections estimating an increase to 68% by 2050, a projected additional 1.2 million km2 land be converted 20301. Poor practice construction industry, lack established processes and practitioners undertake surveys assessing soils health prior development, as well loopholes laws policies are key factors affecting soil during construction. Millions tonnes coming from sites being disposed landfill2 but 90%...
Abstract Among the numerous causes of soil degradation, one most severe and difficult to reverse is land take. Land take results in loss valuable ecosystem services that negatively impact health, especially agricultural areas. The main drivers are increased provision housing, schools, hospitals, industrial commercial sites, transport networks infrastructures, mines, quarries waste dumpsites. Globally, rate scale increasing. Given on such as carbon, hydrological nitrogen cycles, preventing...
Abstract Increasing CO 2 levels are a major global challenge, and the extent to which increasing anthropogenic emissions can be mitigated by natural carbon sinks remains poorly understood. The uptake of elevated (eCO ) terrestrial biosphere, subsequent sequestration as biomass in ecosystems, may act negative feedback budget, but hard quantify ecosystems. Here, we combine large-scale field observations fine root stocks flows, derived from belowground imaging soil cores, with image analysis,...
In this research we consider the response of soil respiration under elevated CO2 (eCO2) in an oak-dominated temperate forest. We hypothesised that (550 ppm) moisture would increase as a result reduced stomatal conductance, which turn lead to higher respiration. Continuous measurements were performed on three pairs plots near Stafford (United Kingdom). Respiration was measured diurnally for 2 minutes each time, using LI-COR 8100A set-up, and rate (flux rate) calculated SoilFluxPro software....
Anthropogenic CO2 emissions have resulted in elevated (eCO2) the atmosphere, and this rise is predicted to continue1. Increases fertilised forest ecosystems led an uptake of into plant soil biomass. Early findings at BIFoR FACE (Free-Air Carbon Dioxide Enrichment) showed increased photosynthetic uptake2, fine root net primary productivity3 respiration4, indicating carbon (C) allocation belowground mirroring previous experiments. Roots play a key role whole-plant functions, biogeochemical...
Whether photosynthesis under elevated CO2 (eCO2) will promote increases in net primary productivity depends on whether plants can access additional essential nutrients. While increasing to nutrients may be possible young forests that have not explored their whole soil environment, it is unknown mature perform similarly eCO2. Soil respiration (Rs) and nutrient bioavailability are sensitive integrative measurements of biogeochemistry temperate forests. However, little known about how these...
