Understanding the relationships between climate and carbon exchange by terrestrial ecosystems is critical to predict future levels of atmospheric dioxide because potential accelerating effects positive climate–carbon cycle feedbacks. However, directly observed CO2 with atmosphere across biomes continents are lacking. Here we present data describing net ecosystem (NEE) factors as measured using eddy covariance method at 125 unique sites in various over six a total 559 site-years. We find that...
Abstract Lolium perenne and Trifolium repens were grown in a Free Air CO 2 Enrichment (FACE) system at elevated (600 μimol mol‐ 1 ) ambient (340 μmol carbon dioxide concentrations during whole growing season. Using root ingrowth bag technique the extent to which enrichment influenced growth of L, T. roots under two contrasting nutrient regimes was examined. Root bags inserted for fixed time into soil order trap roots. It also possible follow mortality different intervals. both L. increased...
ABSTRACT Grasslands play a critical role in providing diverse ecosystem services. Sown biodiverse pastures (SBP) rich legumes are an important agricultural innovation that increases grassland productivity and reduces the need for fertilisers. This study developed machine learning model to obtain spatially explicit estimations of SBP, based on field sampling data from five Portuguese farms during four production years (2018–2021) under two fertilisation regimes (conventional variable rate)....
Many Portuguese pastures face a risk of desertification, but including biochar may enhance the soil sponge function and help mitigate this threat. This study examines biochar's climate change mitigation potential as climate-smart management strategy. It its effects on GHG emissions properties in hardsetting pasture under current projected rainfall conditions. Biochar was incorporated to depth 20 cm at 3% gravimetric concentration October 2022. The field site is biodiverse sown Quinta da...
Small islands offer unique conditions for studying human-nature relations. Our study uses the real-world laboratory concept to reflect on a long-term transdisciplinary research process that aimed facilitate sustainability transition an entire island.This article introduces Greek island of Samothraki, aiming at solutions are not only scientifically sound, but also co-designed, well received and adopted by local community. We 15 years socioecological utilizing conceptual lens laboratories...

Soil microbial community structure is determined by environmental conditions and influenced other factors, such as the intensity of land use management. Studies addressing effect factors management on grassland soil communities at continental scale are missing, wide range ecosystem services provided these ecosystems thus also wanting. To address this knowledge gap, study presents data along a pan-European agro-ecological gradient. The transect included five geographical locations (Sweden,...
On the Greek island of Samothraki, decades overgrazing by large domestic population small ruminants accelerated soil degradation and surface erosion, with direct consequences for ecosystem functioning delivery services. This manuscript reports on a 5-year research project to achieve more sustainable pasture management practices among ruminant farmers island, through introduction Sown Biodiverse Pastures (SBP). practice, based sowing seed mixture legumes grasses that increase productivity,...
Using open-top chambers, four prominent species ( Lolium perenne, Cynosurus cristatus, Holcus lanatus and Agrostis capillaris ) of Irish neutral grasslands were grown at ambient elevated (700 μmol mol -1 atmospheric CO 2 for a period 8 months. The effects interspecific competition on plant responses to enrichment investigated by growing the in four-species mixture. results indicate that differ their ability respond . -enrichment had largest effect biomass production H. , but substantial...
The southern Iberian Peninsula is characterized by evergreen oak woodlands (locally known as montado), which constitute an important savanna-type agro-silvo-pastoral ecosystem. This ecosystem facing a progressive decline for several reasons, with the foremost being overgrazing. Better management tools are necessary to accurately quantify systems’ carrying capacity and sustainable stocking rates that prevent land degradation. purpose of this study was determine whether MOHID-Land model could...
Introduction: Soil organic carbon (SOC) sequestration is one of the main ecosystem services provided by well-managed grasslands. In Mediterranean region, sown biodiverse pastures (SBP) rich in legumes are a nature-based, innovative, and economically competitive livestock production system. As co-benefit increased yield, they also contribute to through SOC accumulation. However, monitoring SBP require time-consuming costly field work. Methods: this study, we propose an expedited...
Abstract To date, the implications of predicted greater intra‐annual variability and extremes in precipitation on ecosystem functioning have received little attention. This study presents results leaf‐level physiological responses five species covering functional groups grasses, forbs, legumes understorey a Mediterranean oak woodland, with increasing variability, without altering total annual inputs. Although extending dry period between events from 3 to 6 weeks led increased soil moisture...
