Abstract Since 1988, there has been, on average, a 91% increase in dissolved organic carbon (DOC) concentrations of UK lakes and streams the Acid Waters Monitoring Network (AWMN). Similar DOC increases have been observed surface waters across much Europe North America. Much debate about causes rising has, as other studies relating to cycle, focused factors related climate change. Data from our peat‐core experiments support an influence DOC, notably production with temperature under aerobic,...
Abstract. Soils play a pivotal role in major global biogeochemical cycles (carbon, nutrient, and water), while hosting the largest diversity of organisms on land. Because this, soils deliver fundamental ecosystem services, management to change soil process support one service can either provide co-benefits other services or result trade-offs. In this critical review, we report state-of-the-art understanding concerning biodiversity soil, relate these provisioning, regulating, supporting,...
Abstract Dissolved organic carbon ( DOC ) concentrations in surface waters have increased across much of E urope and N orth A merica, with implications for the terrestrial balance, aquatic ecosystem functioning, water treatment costs human health. Over past decade, many hypotheses been put forward to explain this phenomenon, from changing climate land management eutrophication acid deposition. Resolution debate has hindered by a reliance on correlative analyses time series data, lack robust...
Climate change in the UK is expected to cause increases temperatures, altered precipitation patterns and more frequent extreme weather events. In this review we discuss climate effects on dissolved organic matter (DOM), how DOM water physico-chemical properties will affect treatment processes assess utility of techniques used remove monitor quality. A critical analysis literature has been undertaken with a focus catchment drivers character, removal via coagulation formation disinfectant...
Abstract A strong relationship between dissolved organic carbon (DOC) and sulphate (SO 4 2− ) dynamics under drought conditions has been revealed from analysis of a 10‐year time series (1993–2002). Soil solution blanket peat at 10 cm depth stream water were collected biweekly weekly intervals, respectively, by the Environmental Change Network Moor House‐Upper Teesdale National Nature Reserve in North Pennine uplands Britain. DOC concentrations soil closely coupled, displaying seasonal cycle...

Abstract The production and release of dissolved organic carbon (DOC) from peat soils is thought to be sensitive changes in climate, specifically temperature rainfall. However, little known about the actual rates net DOC response water table draw‐down, particularly comparison dioxide (CO 2 ) fluxes. To explore these relationships, we carried out a laboratory experiment on intact soil cores under controlled conditions determine impact interaction each climatic factors production. We found...

Abstract Soils are the largest terrestrial pool of organic carbon, with up to 50% soil carbon (SOC) stored below 30 cm. Knowledge impact land use on mechanisms by which SOC is in subsoils critical developing and delivering strategies mitigate climate change.

A role for TNF-alpha in the pathogenesis of chronic inflammatory disease is now firmly established. Paradoxically, TNF also has potent immunomodulatory effects on CD4(+) T lymphocytes, because Ag-specific proliferative and cytokine responses are suppressed following prolonged exposure to TNF. We explored whether attenuated cell activation by uncoupling proximal TCR signal transduction pathways using a mouse hybridoma model. Chronic induced profound, but reversible, hyporesponsiveness, with...
It is of wide interest to understand how opposing extracellular signals (positive or negative) are translated into intracellular signaling events. Receptor–ligand interactions initiate the generation bioactive lipids by human neutrophils (PMN), which serve as orchestrate cellular responses important in host defense and inflammation. We recently identified a novel polyisoprenyl phosphate (PIPP) pathway found that one its components, presqualene diphosphate (PSDP), potent negative signal PMN...
The relationship between dissolved organic carbon (DOC) and the acidification of soils freshwaters by sulfate (SO42-) has been a topic great debate over last few decades. Most interest focused on long-term acidification. Few have considered influence episodic drought-induced in peatlands DOC mobility, even through increased acidity ionic strength associated with oxidation reduced sulfur to SO42- are known reduce solubility. Reduced concentrations during droughts often attributed to: (i)...
