In the classical plenary lecture ‘Global limnology’ (J.A. Downing, 2007, SIL in Montréal), a new holistic direction for freshwater science was pointed out, focused at upscaling of limnological processes to planet Earth. Since then, the literature on the global importance of freshwater networks, especially as routes for carbon degassing, burial and transport, has grown explosively. This has been re
In spite of substantial greenhouse gas emissions from photo-degradation of dissolved organic carbon (DOC), little is known about the variability in DOC photo-reactivity. It has been suggested that photo-reactivity depends on the degree of DOC pigmentation. However, recent evidence suggests that also non-colored fractions can be photo-reactive. Furthermore photo-degradation processes interact with
The contribution of terrestrially-derived carbon to micro-crustacean zooplankton biomass (i.e. allochthony) has been previously studied in lakes and reservoirs, but little is known about allochthony in rivers. We hypothesized that restricted selective grazing in turbulent environments such as rivers would decouple zooplankton from specific microbial and algal food resources, such that their alloch
Swedish alpine and subarctic areas undergo rapid transitions due to climate change, especially in relatively humid areas where the forest vegetation is expanding. It has been suggested that lakes in these areas are in transition from clearwater into brownwater state, because of the humus layer building up in surrounding soils, with negative consequences, e.g., for the biomass production of zooplan
Planktonic community respiration is an important carbon cycling process, typically quantified by converting measured values of dissolved oxygen consumption rates into carbondioxide production rates using a respiratory quotient of 1 (RQ = carbondioxide per oxygen by moles). However, the true variability in planktonic RQs between different aquatic ecosystems is poorly understood. We conducted in sit
The stable carbon isotope ratio (δ13C) is a key tool in tracing the source of carbon within and across ecosystems. In isotope mixing models dissolved organic carbon (DOC) from terrestrial sources is often assigned a fixed δ13C of roughly -28‰ to -27‰ in C3 plant-dominated areas. However, the claim of a uniform δ13C distribution for terrestrial DOC sources of different reactivity has seldom been te
What explains subnational policy choices over tax cut after decentralization? We test two different explanations in the context of the 2002 tax reform in Russia. A popular strand of literature suggests that decentralization induces more regional competition over investment, motivating subnational tax cuts. A second body of literature suggests that personal business interests of regional governors
We present a detailed measurement of charged two-pion correlation functions in 0-30% centrality sNN=200 GeV Au+Au collisions by the PHENIX experiment at the Relativistic Heavy Ion Collider. The data are well described by Bose-Einstein correlation functions stemming from Lévy-stable source distributions. Using a fine transverse momentum binning, we extract the correlation strength parameter λ, the
Background: This is the second of two papers presenting the results from a study of the implementation of patient online access to their electronic health records (here referred to as Open Notes) in adult psychiatric care in Sweden. The study contributes an important understanding of both the expectations and concerns that existed among health care professionals before the introduction of the Open
Background: Lymphedema may affect patients' health-related quality of life (HRQoL) and thus a disease-specific questionnaire is needed. The Lymphedema Quality of life Inventory (LyQLI) has been tested for reliability and validity. The purpose of this study was to test the LyQLI for responsiveness and sensitivity. Methods and Results: The study participants were patients with lymphedema in the uppe
The Gaia mission is expected to make a significant contribution to the knowledge of exoplanet systems, both in terms of their number and of their physical properties. We develop Bayesian methods and detection criteria for orbital fitting, and revise the detectability of exoplanets in light of the in-flight properties of Gaia. Limiting ourselves to one-planet systems as a first step of the developm
Nod-like receptors (NLRs) are important innate pattern recognition receptors and regulators of inflammation or play a role during development. We systematically analysed 41 non-synonymous single nucleotide polymorphisms (SNPs) in 21 NLR genes in a Czech discovery cohort of sporadic colorectal cancer (CRC) (1237 cases, 787 controls) for their association with CRC risk and survival. Five SNPs were f
This article analyses the effect of cultural diversity on employment growth, considering the recent global financial crisis (GFC) as a moderating factor. In doing so, we developed competing hypotheses based on Blau’s theory of heterogeneity versus an alternative perspective which combines the resource-based view (RBV) with social identity theory (SIT). We empirically test such theories using a uni
Background: The dental characteristics of large plant-eating mammals, such as hypsodonty, quite accurately describe present and past climatic conditions worldwide. However, several peculiar regions give systematically higher predictions of primary productivity than the local average environmental conditions should support. We call these 'anomalies'. Anomalies are prominent in areas dominated by pa
We report on the design and performance of a velocity map imaging (VMI) spectrometer optimized for experiments using high-intensity extreme ultraviolet (XUV) sources such as laser-driven high-order harmonic generation (HHG) sources and free-electron lasers (FELs). Typically exhibiting low repetition rates and high single-shot count rates, such experiments do not easily lend themselves to coinciden
