Temperature is a key constraint on ecosystem respiration but is typically measured at only one or a few points across a study site. Given the exponential relationship between temperature and respiration, small differences in temperature across a heterogeneous ecosystem may result in large differences in respiration fluxes. These differences are not captured in current respiration models which use
The majority of the world’s peatlands are located in northern regions where climate change is occurring most rapidly. Therefore, there is an urgent need to understand whether, and under what conditions, peatlands will remain carbon sinks or become carbon sources. The uncertainties in our predictions stem from a variety of sources, including uncertainty about the competing effects of rising air tem
Boreal forests have a large impact on the global greenhouse gas balance and their soils constitute an important carbon (C) reservoir. Mature boreal forests are typically a net CO2 sink, but there are also examples of boreal forests that are persistent CO2 sources. The reasons remain often unknown, presumably due to a lack of understanding of how biotic and abiotic drivers interact to determine the
The Integrated Carbon Observation System Research Infrastructure aims to provide long-Term, continuous observations of sources and sinks of greenhouse gases such as carbon dioxide, methane, nitrous oxide, and water vapour. At ICOS ecosystem stations, the principal technique for measurements of ecosystem-Atmosphere exchange of GHGs is the eddy-covariance technique. The establishment and setup of an
Research infrastructures play a key role in launching a new generation of integrated long-Term, geographically distributed observation programmes designed to monitor climate change, better understand its impacts on global ecosystems, and evaluate possible mitigation and adaptation strategies. The pan-European Integrated Carbon Observation System combines carbon and greenhouse gas (GHG; CO2, CH4, N
Biogeochemical models use meteorological forcing data derived with different approaches(e.g. based on interpolation or reanalysis of observation data or a hybrid hereof) to simulateecosystem processes such as gross primary productivity (GPP). This study assesses theimpact of different widely used climate datasets on simulated gross primary productivity andevaluates the suitability of them for repr
Global warming is expected to transfer carbon from soil organic matter to atmospheric CO 2, with microbial communities playing a crucial role in regulating this exchange. While the immediate impact of temperature on microbial functions is well understood and causes soil carbon losses, the long-term response remains unclear, with losses stabilising over time, reducing the overall effect of chronic
Boreal forests emit terpenoid biogenic volatile organic compounds (BVOCs) that significantly affect atmospheric chemistry. Our understanding of the variation of BVOC species emitted from boreal ecosystems is based on relatively few datasets, especially at the ecosystem-level. We conducted measurements to obtain BVOC flux observations above the boreal forest at the ICOS (Integrated Carbon Observati
ContextPrimary forests, with little to no direct human impact, can serve as baselines to assess land-use effects. However, most have been converted for other land-uses and the locations and characteristics of the remaining forests are poorly characterized.ObjectivesThis study presents a map of Swedish primary forests, explores their persistence in a managed landscape, and assesses their suitabilit
Old-growth forests uniquely support biodiversity while serving as some of the planet's most important carbon stocks. The influence of tree and stand age on carbon flux dynamics remains debated—an urgent question as climate-driven disturbances may reshape forest age structures and in situ carbon storage. To clarify these relationships in Fagus sylvatica , systems, we examined a unique dataset of 3,
This study investigates isoprene emissions in a high-latitude Alpine tundra ecosystem, focusing on using near-field remote sensing of surface temperatures, the photochemical reflectance index (PRI) and normalized difference vegetation index (NDVI), and meteorological measurements to model these emissions. Isoprene is a key biogenic volatile organic compound (BVOC) emitted by select plants, which c
This article applies a conceptual framework based on multilevel theories of gender inequality to examine individual-level food insecurity (FI) outcomes in the League of Arab States (LAS). We conceptualize FI as an embodied waypoint on a discriminatory cycle incorporating material and cultural practices that function at macro-, situational-, and individual-levels. Using data drawn from the Gallup W
Increasing drought frequency and intensity affect biophysical functions of natural ecosystems. In tropical semi-arid savannas, while immediate drought effects are well-studied, the drought legacy effects on vegetation composition and associated ecosystem functions remain unclear. We used data of vegetation composition, net ecosystem CO 2 exchange, surface albedo and evapotranspiration (ET) in 201
The stable isotope ratios of carbon (δ13C(CH4)) and hydrogen (δ2H(CH4)) in methane (CH4) from atmospheric air samples provide a tracer that can help distinguish the relative contribution of emission sources. These can be continuously measured at atmospheric monitoring stations by optical isotope ratio spectrometer (OIRS) instruments, providing data that is complementary to isotope ratio mass spect
Tropical rainforests have complex responses to seasonal climatic variations. Compared to the Amazon and Asian rainforests, the Congo rainforest exhibits a more widespread bimodal seasonal pattern, yet it remains understudied. Here, we use three independent satellite-based vegetation indices to investigate the seasonal variations of the Congo rainforest, including solar-induced chlorophyll fluoresc
Dissolved Organic Carbon (DOC) is a key component of the inland water carbon cycle, playing a critical role in water quality, aquatic ecosystem dynamics, and carbon flux assessments. In this study, we combine Sentinel-2 Multi-Spectral Instrument (MSI) data with in-situ water quality, meteorological, and temporal variables to predict DOC concentrations in Lake Erken, Sweden.
