Vegetative stage and soil horizon respectively determine direction and magnitude of rhizosphere priming effects in contrasting tree line soils

Functional Ecology, Volume 38, Issue 9, Page 1984-2002, September 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tree lines in high latitudes and high altitudes are considered sentinels of global change. This manifests in accelerated encroachment of trees and shrubs and enhanced plant productivity, with currently unknown implications for the carbon balance of these biomes.

Plant‐based meat analogues marketed in Catalonia: analysis of contaminants, essential elements, microbiological and physicochemical status, dietary intake estimation and health risk assessment

Food Risk Assess Europe, Volume 2, Issue 3, July 2024.
Abstract The latest barometer of food safety in Catalonia conducted by the Catalan Food Safety Agency (ACSA for its initials in Catalan) in 2021 shows that 28.7% of the population consumes meat analogues (substitutes). The main reasons for consuming this type of food are animal welfare, followed by environmental and health reasons.

Multiple stressors alter greenhouse gas concentrations in streams through local and distal processes

Global Change Biology, Volume 30, Issue 5, May 2024.
We found that the simultaneous occurrence of several human‐induced stressors in streams increases the concentrations of greenhouse gases in their waters, potentially exacerbating climate crisis. Our results also indicate that the scale at which human impacts occur has different effects on carbon dioxide and methane concentrations.

Pushing the limits of C3 intrinsic water use efficiency in Mediterranean semiarid steppes: Responses of a drought‐avoider perennial grass to climate aridification

Functional Ecology, Volume 38, Issue 4, Page 955-966, April 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intrinsic water use efficiency (WUEi) reflects the trade‐off between photosynthetic carbon gain and water loss through stomatal conductance and is key for understanding dryland plant responses to climate change.
