Norway spruce shows stronger growth sensitivity and weaker intrinsic water-use efficiency response than Scots pine under increasing water limitation in southern Finland

Abstract. Boreal forests, essential for carbon sequestration and multiple ecosystem services, face increasing pressure from climate-induced water stress. This study investigates how increasing water limitation affects growth and intrinsic water-use efficiency (iWUE) in Scots pine...

A method quantifying soil melanin to understand fungal impacts on soil carbon stability

Abstract Fungal necromass, particularly dead microbial cells rich in melanin, is an important contributor to long-term soil carbon stabilization. Progress in understanding the role of soil melanin is limited by the lack of validated analytical methods. DNA-based approaches estima...

Drought responses of a Norway spruce forest on drained peat soil: combining sap-flow sensors, eddy-covariance, meteorological, soil and UAV data

Abstract. The summer of 2021 brought a severe drought to southern Finland. We explored how a drained boreal peatland forest responds to drought by combining a wide range of in situ monitoring and Unmanned Aerial Vehicle (UAV) remote sensing. A dataset combining eddy-covariance (E...

Landscape composition and photoperiod shape differences in space use and hunting behaviour between boreal and Alpine pygmy owl populations

Abstract Context Investigating how habitat specialists express population-level differences in habitat preferences and movement behaviour across contrasting landscapes and abiotic environments allows us to distinguish patterns that are consistent across populations from those tha...

Spring migration passage advances can be counteracted by range shifts

Long-term passage records of migrating birds from fixed observatories are widely used to infer spring migration phenology. Yet migrants recorded at a site need not represent a constant mixture of populations over time. Spring onset and optimal arrival occur later at higher latitu...

Approximating prediction error variances and reliabilities in a multiple-trait genomic prediction model using Monte Carlo sampling

Abstract Key message We evaluated four existing Monte Carlo-based methods for approximating prediction error variances and reliabilities in a multiple-trait genomic prediction model. All four methods yielded consistent approximations of the exact values. Abstract Genomic predicti...

Environmental drivers of litter- and soil-dwelling springtail communities across European forests, assessed by morphotaxonomy and soil DNA metabarcoding

Springtails are abundant in forest litter and soils, where they play a crucial role in the transformation and decomposition of organic matter. However, most data on springtail communities originates from studies at the local and regional levels, while larger-scale studies are lac...

Operationalizing the Concept of Socio-environmental Tipping Points in River Basin Management

Abstract The concept of socio-environmental tipping points (SETPs) is gaining interest as a means to describe nonlinear transformations in socio-environmental systems that are driven by both biophysical and social dynamics. These SETPs stem from multiple interacting factors that...

Soil–plant interactions during early vegetation growth govern HONO, NO and N2O emissions through moisture, temperature, and mineral N pools in boreal agricultural soils

Abstract Background and aims Reactive nitrogen gases (HONO, NO, N 2 O) are key to atmospheric chemistry and climate forcing, yet their simultaneous in-situ emissions from boreal agricultural soils are poorly known. We aimed to quantify these gases during early crop growth, a peri...
