Effects of Controlled Mycorrhization and Deficit Irrigation in the Nursery on Post-Transplant Growth and Physiology of <i>Acer campestre</i> L. and <i>Tilia cordata</i> Mill.

The goal of this work was to assess the effects of mycorrhizal inoculation and deficit irrigation applied in the nursery on the post-transplant growth and physiology of Acer campestre L. and Tilia cordata Mill. For this purpose, 144 preconditioned plants were planted in an experimental plot in northern Italy and were monitored for three growing seasons. Controlled inoculation in the nursery enhanced the root colonization rate three years after transplanting only in Acer campestre. Inoculated Acer campestre showed higher survival, shoot length, turgor potential and leaf gas exchange than non-inoculated plants throughout the experiment. By contrast, in Tilia cordata, no difference in root colonization by mycorrhizal fungi was observed between plants inoculated or not in the nursery three years after transplanting. Indeed, the survival, growth and physiology of Tilia cordata after transplanting were little affected by inoculation. Deficit irrigation in the nursery determined higher survival, growth and CO2 assimilation rate and more favorable water relations in newly transplanted Acer campestre. By contrast, Tilia cordata exposed to deficit irrigation in the nursery showed lower growth and unaffected survival after transplanting compared to plants which received full irrigation in the nursery. The overall results suggest that nursery preconditioning through mycorrhizal inoculation and deficit irrigation can affect post-transplant performances, although their effectiveness depends on species’ mycorrhizal dependency and water use strategy

Interlinkages between Climate Change Impacts, Public Attitudes, and Climate Action—Exploring Trends before and after the Paris Agreement in the EU

European member states have high emission reduction potential. They send a strong signal to the rest of the world with their action or inaction on climate change. Yet, within the EU, national-level climate policies (NLCP) lag behind the EU Commission’s overall climate goals. Transparency of and accountability for climate action requires an integrative perspective. Here, insights from diverse research disciplines address the following questions: How are climate impacts, public attitudes, and climate policies changing over time, and what are the interlinkages? Using three databases (Germanwatch (CCPI), European Extreme Events Climate Index (E3CI), and Eurobarometer Public Opinion Survey, 27 European countries were compared for NLCP (mitigation), climate change impacts (heat/drought), and public attitudes towards climate change (cognition/affect/conation). Differences among groups before and after the Paris Agreement were evaluated with ANOVA tests; trends and geographical differences were analysed with linear models. NLCP did not improve after the Paris Agreement, even displaying some deterioration in the eastern macro-region. Conversely, public awareness towards climate change is improving, with concern being higher in northern compared with southern countries. Heat stress is significantly related to NLCP, with increases in heat stress corresponding to improved climate policy in the northern region while worsening it in the southern region. Under worsening climate impacts, public attitudes increasingly favour climate action. However, overall policy responses are inadequate, although differences occur at the macro-regional level. The results provide granular insights into a persistent knowledge–action gap

Fire-smart solutions for sustainable wildfire risk prevention: Bottom-up initiatives meet top-down policies under EU green deal

Fuel management for wildfire risk prevention generally lacks economic sustainability. In marginal areas of southern Europe, this limits fuel treatment programs from reaching the critical mass of required treated area to modify landscape flammability, the fire regime and its impacts. This study investigates key fuel management initiatives for wildfire risk prevention in southern EU countries. We compared local approaches through a bottom-up selection of 38 initiatives, which we analyzed systematically through a set of fire-smart criteria: sustainability, cost-benefit ratio, synergies and inter-sectoral cooperation, integration between strategic prevention planning and multiple land governance goals (e.g., rural development, biodiversity conservation, energy supply), innovation and knowledge transfer, and adaptive management. We summarized lessons learned from the most innovative initiatives, by identifying solutions and functional approaches for building sustainable fuel management at the landscape scale, under fire-smart management principles. These make synergistic use of private, public and European resources to activate value chains that valorize the products, by-products and services generated by fuel management activities and their positive externalities on ecosystem services. The multiple mechanisms include fire-marketing, Payment for Ecosystem Services schemes, specific taxes, or environmental compensatory measures. These mechanisms catalyze the interest of multiple stakeholders (economic actors, private owners, land and fire management agencies) improving the cost-efficiency of landscape fuel management. We contend that the EU Green Deal offers the political backing and framework (mainstreaming of EU strategies and funding opportunities) to enable the replication of documented fire-smart models and functional approaches to wildfire risk prevention.17s

A multi-element psychosocial intervention for early psychosis (GET UP PIANO TRIAL) conducted in a catchment area of 10 million inhabitants: study protocol for a pragmatic cluster randomized controlled trial

Multi-element interventions for first-episode psychosis (FEP) are promising, but have mostly been conducted in non-epidemiologically representative samples, thereby raising the risk of underestimating the complexities involved in treating FEP in 'real-world' services
