Developing accurate large-scale drought prediction models is challenging due to the complex temporal and spatial correlation patterns that govern drought dynamics, as well as the compounding effects of anthropogenic activities and global climate change. Although recent advances in deep learning have yielded effective drought prediction models, many struggle to fully capture the heterogeneous spati
Climate change and land-use change represent a dual threat to terrestrial ecosystem functioning. In the tropics, forest conversion to agriculture is occurring alongside warming and more pronounced periods of drought. Rainfall after drought induces enormous dynamics in microbial growth (potential soil carbon storage) and respiration (determining carbon loss), affecting the ecosystem carbon budget.
Global change is altering forests worldwide, with multiple consequences for ecosystem functioning. Temporal changes in climate, and extreme, compounded weather events like hotter droughts are affecting the demography, composition and function of forests, leading to a highly uncertain future. To accurately predict future forest responses to hotter droughts, we highlight the need for considering a b
Accurately simulating soil organic carbon (SOC) dynamics is essential for carbon-related assessments. Process-oriented SOC models employ temperature (f(T)) and soil moisture (f(W)) response functions derived from specific conditions to simulate SOC responses to climate change, yet are widely applied in regional and global-scale studies. How these functions affect regional SOC simulations remains u
Aim: Our primary aim was to assess how dispersal limitation affected forest changes in the Northern Hemisphere during the last glacial cycle, and especially after the last deglaciation. Location: Northern Hemisphere (between 20°N and 80°N). Time Period: 50,000–0 years before present. Major Taxa Studied: Angiosperms and gymnosperms. Methods: We used the LPJ-GM 2.0 dynamic global vegetation model to
The impact of livestock grazing on soil organic carbon (SOC) stocks in the Sahel has been poorly documented due to a lack of data from different grazing intensities. This study evaluated SOC stocks under four grazing intensities within 0–30 cm soil depth in dry savanna ecosystems of Senegal. It also examined possible indirect relationships between grazing and SOC through herbaceous species diversi
Whilst the importance of fungal primary biological aerosol particles (PBAPs) has been recognised, few studies have empirically assessed how land-use patterns influence them. Here, we show the impacts of different land-use patterns on fungal PBAPs within the Brazilian Atlantic Forest biodiversity hotspot. Spanning a distance of ca. 600 km within this biome, we collected fungal bioaerosols in the fo
Temperature impacts on microbiological processes are crucial for soil biogeochemistry and ecosystem functioning, yet existing models either fail to capture microbial temperature dependences across the full biokinetic range or risk overparameterization. Here we present the “Dual-Kinetics Ratkowsky” model (Ratkowsky DK), which simultaneously describes temperature dependences of microbial growth and
This study analyzed daily temperature data from 114 meteorological stations in the Qinling-Daba Mountains from 1980 to 2017, focusing on core zones (CE I ≥ 2274 m, CE II 1321–2274 m) and peripheral zones (PE I 668–1321 m, PE II < 668 m). Using 15 extreme temperature indices computed with RClimDex, we assessed the spatiotemporal patterns, trends, and response to climate warming of extreme temperatu
Radiation dosimetry and cancer risk estimations are central to virtually all radiation safety applications, optimization, and research. These estimates relate to various exposure situations including planned, existing, and emergency situations. The International Commission on Radiological Protection (ICRP) has developed a new methodology to handle the dosimetry of an acute/single intake of radionu
The dynamics of atmospheric CO2 concentrations during and following the last deglaciation have mainly been ascribed to carbon release from and uptake in oceans, primarily in the Southern Ocean. But recent studies also point toward a terrestrial influence. We quantify dynamic changes to northern terrestrial carbon stocks from the Last Glacial Maximum (21,000 years) until present at millennial time
The Alzheimer’s Association and the Society of Nuclear Medicine and Molecular Imaging convened a multidisciplinary workgroup to update appropriate use criteria (AUC) for amyloid positron emission tomography (PET) and to develop AUC for tau PET. Methods: The workgroup identified key research questions that guided a systematic literature review on clinical amyloid/tau PET. Building on this review, t
Avian haemosporidian parasites are globally widespread with a broad repertoire of hosts. When infected, the host can either reduce (resistance) and/or limit the severity of parasitaemia (tolerance). Oxidative stress plays a pivotal role in the host's resistance and tolerance, as well as its detrimental endpoints. The rationale behind this paradox lies in the dual role of reactive oxygen species (R
Naturbetesmarker och slåtterängar är bland de mest artrika miljöerna i det svenska jordbrukslandskapet och har därför en avgörande betydelse för bevarandet av biologisk mångfald. För att uppfylla kraven i EU:s Naturrestaureringsförordning och de nationella miljökvalitetsmålen krävs att Sverige både bevarar befintliga gräsmarker med höga naturvärden och restaurerar betydande arealer så att de erhål
Mercury (Hg) has been stored in permafrost peatlands for millennia. As permafrost thaw is predicted to increase with ongoing climate warming, Hg is at risk to be remobilized from those peatlands and hotspots for Hg methylation could potentially form. Monomethylmercury (MeHg) is a known neurotoxin and a health concern to northern communities if Hg is remobilized, transformed to MeHg and subsequentl
