Modified Biochar for Wastewater Nutrient Recovery and Slow‐Release Fertilization in Sandy Agroecosystems

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Modified biochars are increasingly recognized as multifunctional materials for wastewater nutrient recovery and slow‐release fertilization in sandy agroecosystems. This review evaluates modified biochars, with particular emphasis on tyre‐derived biochar (TBC), for (i) recovery of nitrogen (N) and phosphorus (P) from wastewater and digestate ...

Navigating Guaiacyl and Syringyl Lignin Structural Complexity in Intact Plant Cell Walls Through 13C Chemical Shift Mapping by Two‐Dimensional Solid‐State NMR

open access: yesMagnetic Resonance in Chemistry, EarlyView.
We establish a two‐dimensional solid‐state NMR 13C chemical shift mapping framework that resolves diagnostic features and explicitly visualizes spectral overlap among guaiacyl and syringyl lignin substructures in intact plant cell walls. Application across Arabidopsis genotypes and developmental stages, hardwoods, and softwood reveals distinct lignin ...

FennoTraits: dataset of plant functional traits and community composition in northern European flora

open access: yesNordic Journal of Botany, EarlyView.
We present here FennoTraits, a dataset of plant functional trait and community composition data collected from Fennoscandia across northern Finland, Norway, and Sweden in 2016–2025. This dataset has 42 049 abundance estimations and 155 794 site‐level functional trait observations from 10 traits representing 373 vascular plant species collected from ...

Species‐specific browsing constraints on tree recruitment may curb conifer treeline expansion in the Arctic

open access: yesOikos, EarlyView.
Treelines at the forest–tundra ecotone are often shifting to higher elevation and latitudes in response to global warming, yet not all treeline positions match the climatic maximum range. This mismatch often reflects the interplay between various factors, including historical land use legacies, propagule dispersal capacity and herbivore impacts on ...

Dissolved organic carbon and nitrogen leaching from Scots pine, Norway spruce and silver birch stands in southern Sweden [PDF]

open access: yes, 2011
The effects of three common tree species – Scots pine, Norway spruce and silver birch – on leaching of dissolved organic carbon and dissolved nitrogen were studied in an experimental forest with podzolised soils in southern Sweden. We analyzed soil water

Spruce Bark Biorefinery

open access: yes, 2013
Norway spruce Picea abies is a key raw material for the forest industry in the Nordic countries. In order to improve the competitiveness of the forest industry by valorising residues and creating value from new products, we have studied the upgrading of spruce bark into transport fuels and chemicals.

Technical wildness: Modernity, romanticism, and the technocratic turn in Scottish rewilding

open access: yesPeople and Nature, EarlyView.
Abstract Technical wildness is a new and increasingly influential culture of nature. This paper marks its emergence in Scotland in the early 2020s. Focusing on Scotland's rapidly evolving land management sector, the paper traces how private rewilding companies position science‐led land management and natural capital markets as the most effective ...

Spruce Beetles Attack Slowly Growing Spruce

open access: yesForest Science, 1985
Abstract White spruce ( Picea glauca (Moench) Voss) stands were examined in 1982 to determine the relationship of tree growth to spruce beetle attack in an active spruce beetle ( Dendroctonus rufipennis (Kirby)) infestation on the ...
