Effective environmental policies for the tropics depend on accurate, representative scientific data. However, there is strong evidence from particular disciplines and regions that existing research is patchily distributed. Here, we show that poor representation of sampling and citation in some biomes and across key environmental gradients from all disciplines for the entire tropics may lead to fla

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 2017

ObjectivesPeople with serious illness approaching end of life often end up in emergency and hospital care, frequently against expressed preferences. Consequently, oncology trials record care days as a measure of treatment burden called “time toxicity.” However, this measure ignores the diminishing marginal utility of time: that the value of a day is higher when fewer remain. We aimed to incorporat

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

Relaxed eddy accumulation (REA) measurements for 14CO2 enable the estimation of fossil fuel (ff) CO2 fluxes in urban areas. This work is based on 252 REA ffCO2 flux measurements conducted on tall towers in the cities of Zurich, Paris, and Munich. The ffCO2 fluxes were compared to net eddy covariance CO2 fluxes to quantify the role of non-fossil (nf) CO2 fluxes. While the measurements in Zurich and

While many studies have examined carbon dynamics of boreal ecosystems following wildfire, research on forest-atmosphere carbon fluxes during widespread smoke events from adjacent active wildfires is limited. We examined eddy covariance carbon exchange adjacent to the May 2011 Utikuma Complex wildfire in central Alberta, Canada. Over a one-week period while the wildfire was burning <10 km from the

The future role of boreal forests in the global carbon cycle is uncertain given the rapid climate change in high latitudes. At the landscape scale, heterogeneity in stand age and land cover, contributions from terrestrial and aquatic fluxes, and harvest export may create complex carbon cycle-climate interactions. However, the integrated response of the net landscape carbon balance (NLCB) to inter-

Deposition of phosphorus (P) is important for the nutrient supply to forests and open land but also contributes to the eutrophication of surface waters. Deposition to open land can be measured as bulk deposition while deposition to forests cannot be measured directly, due to internal circulation of P within forest canopies. This study aimed to quantify the total deposition of P to open land and fo

This study investigates possible structural changes of an intrinsically disordered protein (IDP) when it adsorbs to a solid surface. Experiments on IDPs primarily result in ensemble averages due to their high dynamics. Therefore, molecular dynamics (MD) simulations are crucial for obtaining more detailed information on the atomistic and molecular levels. An evaluation of seven different force f

An increased frequency of droughts due to anthropogenic climate change can lead to considerable stress for soil microorganisms and their functioning within northern peatlands. A better understanding of the diversity and relative abundance of methane producing and oxidizing taxa, and their functional genes, can help predict the functional potential of peatlands and how the microorganisms respond to

To meet complex needs in persons and families within specialist palliative care, care team members are expected to work together in performing a comprehensive assessment of patient needs. Team type (how integrated team members work) and team maturity (group development) have been identified as components in team effectiveness and productivity. The aim of the study reported in this paper was to ide

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and biocl

ObjectivesBeing met with empathy increases information sharing, treatment coherence, and helps patients to recover faster. However, we do not know how the content of the conversation about disease progression, new treatments, or other issues concerning serious illness affects patients' perceptions of the physician's empathy, and thus, the quality of the conversation. This study aimed to test the h

High latitude mires are key ecosystems in the context of climate change since they store large amounts of carbon while constituting an important natural source of methane (CH4). However, while a growing number of studies have investigated methane fluxes (FCH4) at the plot- (~1 m2) and ecosystem-scale (~0.1–0.5 km2) across the boreal biome, variations of FCH4 magnitudes and drivers at the mesoscale

Upplevt socialt stöd, självkännedom och självmedkänsla är faktorer som tidigare visat sig hänga samman med tonåringars livstillfredsställelse och psykiska ohälsa i flera tvärsnittsstudier. Denna studie hade för avsikt att undersöka hur de ovan nämnda variablerna förhåller sig till varandra över tre år och om sambanden mellan socialt stöd och livstillfredsställelse respektive psykisk ohälsa medieraPerceived social support, self-awareness and self-compassion are factors that have previously been shown to be associated with adolescent life-satisfaction and psychological distress in cross-sectional studies. The aim of this study was to examine how these variables relate to each other over three years and whether the relationship between perceived social support and well-being, as well as psych
