Carbon, Nitrogen, and Corresponding Stable Isotope Signatures Reveal Channel Banks as Major Sediment Sources in a Tropical Agricultural Watershed

Land Degradation &Development, EarlyView.
ABSTRACT Uncertainties about the applicability of δ13C and δ15N as tracers of sediment sources in tropical river basins highlight the need for more in‐depth investigations of these isotopes. This study therefore assessed the effectiveness of δ13C and δ15N signatures in discriminating sediment sources in an agricultural catchment in Northeast Brazil ...

The Epidemiology of Aortic Aneurysms: Global and Regional Trends Between 1990 and 2021

Medicine Advances, EarlyView.
This study presents the first comprehensive global analysis of the burden and inequality of aortic aneurysm (AA) using GBD 2021 data across 204 countries and territories. While the overall global burden of AA has declined over the past three decades, our findings reveal a concerning rise in AA‐related mortality and disability‐adjusted life years (DALYs)

The native flora of the Redberry Lake Biosphere Region (Saskatchewan, Canada): taxonomy, biogeography, habitats and conservation

Nordic Journal of Botany, EarlyView.
This study reports for the first time a checklist of native vascular plants and provides a comprehensive analysis of the flora of the Redberry Lake Biosphere Region (RLBR) in the province of Saskatchewan, Canada. To complete an inventory of the regional flora, I conducted intensive field investigations during 2010–2025 and employed detailed examination

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa

Nordic Journal of Botany, EarlyView.
The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.
