The study evaluates the biogeochemical model ForSAFE-2D, designed to simulate water and chemical transport from the forest to the stream, by simulating the hydrology and the transport of the chemical tracer chloride (Cl−) along a forest hillslope in Northern Sweden. The simulated Cl− exports were in balance with the simulated inputs but measurements suggested a net release of Cl− from the catchmen
Background and aims: Betony (Betonica officinalis L.) is one of the rarest and mostspectacular plants in the Scandinavian flora. A long-term question has been whether it is spontaneous or introduced, or whether it comprises both spontaneous and introduced populations. This study aimed to answer this question by analyzing sequence data from the nuclear external transcribed spacer (ETS) region and t
Over 840 M ha of arable land is affected by salinization, and the area is predicted to increase due to global change. Assessments of the status of the microbial community in saline soils have frequently been based on microbial biomass estimates, which might not accurately reflect microbial process rates in soil. Moreover, assessments of how the relative importance of major decomposer groups bacter
Inland waters transport, transform and retain significant amounts of dissolved organic carbon (DOC) that may be biologically reactive (bioreactive) and thus potentially degraded into atmospheric CO2. Despite its global importance, relatively little is known about environmental controls on bioreactivity of DOC as it moves through river systems with varying water residence time (WRT). Here we determ
Introduction: Heterogeneity in composition and spatial configuration of landscape elements support diversity and abundance of flower-visiting insects, but this is likely dependent on taxonomic group, spatial scale, weather and climatic conditions, and is particularly impacted by agricultural intensification. Here, we analyzed the impacts of both aspects of landscape heterogeneity and the role of c
In a future warmer climate, extremely dry, warm summers might become more common. Soil weathering is affected by temperature and precipitation, and climate change and droughts can therefore affect soil chemistry and plant nutrition. In this study, climate change and drought effects on soil weathering rates and release of Ca, Mg, K and Na were studied on seven forest sites across different climates
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
Ectomycorrhizal fungi (EMF) are important components of soil microbial communities, and EMF biomass can potentially increase carbon (C) stocks by accumulating in the soils as necromass and producing recalcitrant structures. EMF growth depends on the C allocated belowground by the host trees, and the nutrient limitation on tree growth is expected to influence this allocation. Therefore, studying EM
Climate change is causing an intensification of soil drying and rewetting events, altering microbial functioning and potentially destabilizing soil organic carbon. After rewetting, changes in microbial community carbon use efficiency (CUE), investment in life history strategies, and fungal to bacterial dominance co-occur. Still, we have yet to generalize what drives these dynamic responses. Here,
Farmers are key to preserving and restoring semi-natural pastures (SNPs) while maintaining their environmental and cultural significance. To support these efforts, it is essential to create favorable conditions that encourages voluntary participation of farmers in agri-environment-climate measures (AECM) for SNP management. This study aims to assess acceptability of contract attributes within AECM
In the low deposition situation of today at many of the long-term Swedish forest monitoring sites, the deposition measured as precipitation to the open field, i.e. bulk deposition of oxidized sulphur (S) is often higher or equal to deposition of S sampled under the forest canopies, i.e. as throughfall. This suggests that the total S deposition estimated using throughfall is underestimated. The rea
This article describes the phonetic characteristics of the most common vocalisation types and subtypes in the domestic cat: the meow, the trill, the howl, the growl, the hiss (and the spit), the snarl (and the cry), the purr, the chirp and the chatter. In addition, the contexts where the different sounds are normally produced, and accompanying body postures and movements are summarised. Acoustic d
Articial intelligence (AI) is widely discussed across policy sectors, including global environmental politics. At the 28th United Nations Climate Change Conference in 2023 (COP28), national governments decided to explore AI’s role in climate solutions and its associated challenges and risks through the #AI4ClimateAction Initiative. In March 2024, the UN General Assembly adopted a resolution to “se
Agricultural management significantly affects insects, especially pollinators, which are crucial for crop pollination and biodiversity. In agricultural landscapes, various factors spanning different spatial scales are known to affect pollinator health, which, in turn, can influence pollination services. However, the importance of these factors in driving the health and performance of different pol
BACKGROUND: The endosymbiotic relationship between Wolbachia bacteria and insects has been of interest for many years due to their diverse types of host reproductive phenotypic manipulation and potential role in the host's evolutionary history and population dynamics. Even though infection rates are high in Lepidoptera and specifically in butterflies, and reproductive manipulation is present in th
The rise of antibiotic-resistant soil microbial communities is a critical global issue. Evidence suggests that heavy metals can select or co-select for tolerance to metals and antibiotics in soil bacteria, but it is unclear if this tolerance varies with land use. We tested the potential of bacterial communities to develop resistance to copper (Cu) or tetracycline (Tet) after amending soils from pr
Peacebuilding initiatives play an important role in the reconstruction of political, economic, and social conditions after internal armed conflicts. If these initiatives also account for environmental aspects, they have the potential to address both ecological damages and resource-related conflict causes. The sprawling literature on environmental peacebuilding therefore stresses the need for a hol
