Holding vs. Using Power: A Dyadic Study of Mediated Power and Responsible Supply Chains

Journal of Supply Chain Management, EarlyView.
ABSTRACT Business organizations must (re‐)evaluate their supply chain practices to foster responsible relationships while adopting strategies to achieve sustainability. Understanding the dynamic interactions among supply chain members is essential for advancing responsible supply chain practices. The authors define responsible supply chain practices as

Influence of human disturbance on the activity patterns and spatiotemporal interactions of wolves and their prey in an Italian stronghold

Journal of Zoology, EarlyView.
The intensification of human activities exerts an influence on animal behaviour, resulting in noticeable shifts in species distributions, movements, and activity patterns. Differential responses among sympatric species, influenced by human disturbance, have the potential to alter species interactions, such as predator‐prey relationships.

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

New Phytologist, EarlyView.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress

New Phytologist, EarlyView.
Significant cross‐tolerance of leaf traits to heat, drought and late spring‐frost were found. (a) Turgor loss point vs lethal spring‐frost temperature. (b) Heat thermal threshold temperature vs lethal spring‐frost temperature. (c) Heat thermal threshold temperature vs turgor loss point.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Water Availability and Hydraulic Strategies Control Leaf Thermoregulation and Damage During Heat Stress and Recovery in Temperate Tree Species

Plant, Cell &Environment, EarlyView.
Abstract Heatwaves are intensifying worldwide, often coinciding with high vapour pressure deficit (VPD) and soil drought. Yet, how temperate tree species tolerate these combined stresses remains elusive. Using single‐tree gas‐exchange chambers, we examined the response of leaf gas exchange and thermoregulation of three broadleaved tree species to a ...

Lack of Hydraulic Acclimation in Response to Multiple Droughts and Recovery

Plant, Cell &Environment, EarlyView.
ABSTRACT Human‐caused climate change is expected to bring more frequent and extended droughts with shorter wet periods of relief in between for many regions of the world. Critical knowledge gaps remain around the extent to which tree species can acclimate physiologically to repeated droughts.

Ecological niches and biogeography of nitrogen‐fixing plants in Europe

Plant Biology, EarlyView.
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

Selective seasonal foraging behavior of herbivores on a Danish island demonstrated by DNA metabarcoding

Restoration Ecology, EarlyView.
Abstract Introduction Understanding how herbivores influence plant communities is critical for managing biodiversity and ecosystem functions, particularly in conservation areas undergoing restoration or rewilding, where free‐ranging large herbivores impact the vegetation development.
