Study region: Rukarara River Watershed (RRW), Rwanda. Study focus: DOC leaching has important environmental consequences for both terrestrial and aquatic ecosystems. This paper measures leached dissolved organic carbon (LDOC) and the factors controlling its variation in the RRW, a mixed agriculture and forest watershed in Rwanda. The study describes the relationship of LDOC with land use/land cove
(“Sources of soil dissolved organic carbon in a mixed agricultural and forested watershed in Rwanda”, [6]) This data article presents water extractable organic carbon (WEOC), percolation water dissolved organic carbon (pDOC), and mean antecedent precipitation indices (API) and mean antecedent temperature (MAT) data. The article also presents edaphic properties such soil texture elements, total org
Recent studies suggest that oncogenic processes (from precancerous lesions to metastatic cancers) are widespread in wild animal species, but their importance for ecosystem functioning is still underestimated by evolutionary biologists and animal ecologists. Similar to what has been observed in humans, environmental modifications that often place wild organisms into an evolutionary trap and/or expo
In 2019, the Climaginaries project ran a climate fiction competition. Out of more than 40 entries, five winners were selected and published in this collection. More of the entries can be found on climaginaries.org/anthroposcenes.
Improving our understanding of the relationships between biodiversity and the delivery of ecosystem services is crucial for the development of sustainable agriculture. We introduce a novel framework that is based on the identification of indicator species for single or multiple ecosystem services across taxonomic groups based on indicator species analyses. We utilize multi-species community data (
In agricultural landscapes, sown flower strips can benefit pollinators and pollination of nearby plants, but their impact on pollination in the wider landscape is poorly studied. We evaluated effects on reproductive success of field bean (Vicia faba) and woodland strawberry (Fragaria vesca) using data from two study systems, both including study sites (1 km radius) with (flower strip sites) or wit
Popular Abstract in Swedish Avhandlingen består av tre empiriska uppsatser inom internationell finansiell ekonomi. Den ekonometriska gemensamma nämnaren är att samtliga använda modeller är av komplex multivariat natur. Därför föreslås att de ekonometriska modellerna estimeras med hjälp av simulated annealing, en stokastisk optimeringsalgoritm som potentiellt löser de problem som vanligtvis är förkThis thesis consists of three self-contained empirical studies on international financial economics. The common economic theme is that all three studies deal with international stock market return and risk. The common econometric theme is that all estimations are performed using simulated annealing, a stochastic optimization algorithm in the Markov Chain Monte Carlo family, in an attempt to solve
Insect herbivory can have important consequences for the functioning of terrestrial ecosystems. Despite a growing recognition of the role of herbivores in above-ground–below-ground interactions, our current understanding is mainly restricted to studies of vertebrates in grassland and tundra ecosystems, while ecosystems with tree-like canopies (termed forests below) and invertebrates remain underst

Ecological compensation is the latest member of a growing family of concepts aimed at reducing degradation of environmental quality. This and other concepts of the family – like ecosystem services, green infrastructure, and nature-based solutions – have been subject to a range of different interpretations and subsequent implementation practices. The result is a complex governance system with uncle
Temperature is a major determinant of biological process rates, and microorganisms are key regulators of ecosystem carbon (C) dynamics. Temperature controls microbial rates of decomposition, and thus warming can stimulate C loss, creating positive feedback to climate change. If trait distributions that define temperature relationships of microbial communities can adapt to altered temperatures, the
Soil microbes perceive drying and rewetting (DRW) events as more or less harsh depending on the previous soil moisture history. If a DRW event is not perceived as harsh, microbial growth recovers rapidly after rewetting (referred to as ‘type 1’ response), while a harsh DRW will be followed by a delayed growth recovery (‘type 2’ response). Predicting these responses based on pedoclimatic factors is
Agricultural expansion and intensification have boosted global food production but have come at the cost of environmental degradation and biodiversity loss. Biodiversity-friendly farming that boosts ecosystem services, such as pollination and natural pest control, is widely being advocated to maintain and improve agricultural productivity while safeguarding biodiversity. A vast body of evidence sh
Remediation of soil contaminated with cadmium (Cd) and lead (Pb) is critical for tobacco production. Silicon (Si) fertilizer can relieve heavy metal stress and promote plant growth, however, it remains unknown whether fertilization with Si can mitigate the effects of Cd and Pb on tobacco growth and alter microbial community composition in polluted soils. Here we assessed the effect of two organic
The microbial use of resources to sustain life and reproduce influences for example, decomposition and plant nutrient provisioning. The study of “limiting factors” has shed light on the interaction between plants and their environment. Here, we investigated whether carbon (C), nitrogen (N), or phosphorus (P) was limiting for soil microorganisms in a subarctic tundra heath, and how changes in resou
