Root exudates are a labile source of carbon (C) for microorganisms that can lead to increased CO2 emission. Root exudates can vary in C:N stoichiometric ratio and their impact on microbially driven soil organic matter (SOM) turnover in paddy soils still remains unclear. The objective was to explore the underlying mechanisms involved in SOM decomposition due to root exudate (artificial) addition wi
Rice paddy agro-ecosystems play an important role in global carbon (C) sequestration. Because of flooding management, paddy soil experience periodical changes in oxygen availability, which may make soil organic carbon (SOC) mineralisation unique as compared to upland or other wetland ecosystems. However, at present, information about the relevant mechanisms involved in paddy SOC mineralisation is
Boreal forests exchange large amounts of carbon dioxide (CO2) with the atmosphere. A managed boreal landscape usually comprises various potential CO2 sinks and sources across forest stands of varying age classes, clear-cut areas, mires, and lakes. Due to this heterogeneity and complexity, large uncertainties exist regarding the net CO2 balance at the landscape scale. In this study, we present the
This report is a result of a cooperation project between Lund University in Sweden and the Koninklijk Nederlands Meteorologisch Instituut, KNMI, in the Netherlands. The overall aim of the project was to provide an initial mapping of providers and purveyors of climate services in the Netherlands and Sweden. In total, 64 organisations participated in the study, through questionnaire replies and/or i
Popular Abstract in Swedish När vi äter kolhydrater, fett, protein och andra näringsämnen sker kemiska reaktioner i kroppen som kan liknas vid dom som sker när man eldar en brasa. Vid förbränning reagerar kolhydrater med syre och bildar koldioxid och vatten. Denna förbränning frigör den energi som funnits lagrad i kolhydraterna, i brasan i form av värme, och i kroppens celler omvandlas den till keNADH:quinone oxidoreductase, or complex I, is a large, complex and poorly understood bioenergetic enzyme in the respiratory chain of living organisms. The enzyme has a conserved core structure, comprising fourteen protein subunits: Seven subunits protrude from the membrane and contain a flavin prosthetic group and eight iron-sulfur clusters that guide electrons from the oxidation of NADH towards t
The effect of mineral fertilization and its application pattern on microbial activity and the subsequent CO2 and CH4 emissions arising from soil organic matter (SOM) or added substrate remains unclear. We quantified the decomposition of 13C-labeled straw and the priming effect (PE) governed by the N and P fertilizer application pattern during a 100-day experiment in a flooded soil. Straw addition
Scholarly literature on science-policy interaction is typically dividedbetween advocating that science and policy need to be broughtcloser together or separated. In a recent article in this journal,Sundqvist and colleagues [Sundqvist et al. (2018) Oneworld ortwo? Science–policy interactions in the climate field, Critical PolicyStudies, 12:4, 448–468] proposed a typology that structures thisdebate.
Large grazers are known to affect ecosystem functioning even to the degree where ecosystems transition to another vegetation state. Alongside the vegetation change, several features of ecosystem functioning, such as ecosystem carbon sink capacity and soil carbon mineralisation rates, may be altered. It has remained largely uninvestigated how the grazing effects on carbon cycling processes depend o
The role of the IPCC as a boundary, or hybrid organization, between science and policy has been well-documented. Much of this research focuses on the role that the IPCC has had in shaping policy outcomes, or how its limitations have potential impacts in uptake and political acceptability of its knowledge claims. Less has been said on its role as an organizer of scientific research. This paper take
Climate change is not only about changes in means of climatic variables such as temperature, precipitation and wind, but also their extreme values which are of critical importance to human society and ecosystems. To inspire the Swedish climate research community and to promote assessments of international research on past and future changes in extreme weather events against the global climate chan
No-tillage (NT) practice is extensively adopted with aims to improve soil physical conditions, carbon (C) sequestration and to alleviate greenhouse gases (GHGs) emissions without compromising crop yield. However, the influences of NT on GHGs emissions and crop yields remains inconsistent. A global meta-analysis was performed by using fifty peer-reviewed publications to assess the effectiveness of

Cryogenic land surface processes (CLSPs), such as cryoturbation, are currently active in landscapes covering 25% of our planet where they dictate key functions, such as carbon (C) cycling, and maintain patterned landscape features. While CLSPs are expected to diminish in the near future due to milder winters especially in the southern parts of the Arctic, the shifts in C cycling in these landscape
Mexico, the second largest economy in Latin America, has almost eradicated extreme poverty according to the Millennium Development Goals; however, official statistics show that by national standards poverty levels are still quite high, reaching up to half its population. This paper looks into how the determinants of poverty in Mexico have evolved after the last major economic crisis the country ex
Understanding greenhouse gas fluxes in semi-arid ecosystems is critical for improving our understanding of biogeochemical cycles, particularly in underrepresented regions like the African Sahel. In these landscapes, greenhouse gas exchange arises from ground, trees, and water ponds, and is further shaped by environmental conditions and grazing. The carbon dioxide, methane, and nitrous oxide fluxes
Transpiration drives up to 40 % of terrestrial precipitation, with forests playing a critical role. This study combines long-term sap flow measurements and surface-based cloud observations to examine how different clouds affect tree transpiration across boreal and temperate European forests. Under specific cloudy conditions, sap flow can exceed clear-sky levels, reflecting distinct radiation effec
