Fire regimes in Mediterranean countries have been shifting recent decades, including changes wildfire size and frequency. We sought to describe fire across two periods (1975–1995 1996–2018) a fire-prone region of central Portugal, explore the relationships between these territorial features, check whether associations persisted periods. Two independent indicators were determined at parish level: incidence burn concentration. Most parishes presented higher values both second period. Higher associated with lower population densities, proportions farmland areas natural vegetation. levels concentration smaller These differed periods, reflecting contrasting climatic socio-economic contexts. Keeping 40% territory covered by was effective buffer increased risks different management climate The effectiveness densities keeping low decreased last decades. results can improve knowledge on temporal evolution their conditioning factors, providing contributions for spatial planning forest/wildfire policies.

Regenerative agriculture aims to boost native biodiversity and ensure sustainable production. Plant Growth Promoting Bacteria (PGPB) enhance crop yield through improved nutrient use efficiency or stress tolerance. Utilizing synthetic bacterial communities (SynCom) tailored specific challenges holds promise for enhancing plant resilience. However, include designing microbial consortia selecting SynCom application techniques. This study tested four PGPB methods on tomato plants evaluate their effectiveness in promoting resistance recovery from short extreme heat waves. Non-invasive phenotyping techniques were used assess responses three delivery (watering, foliar spray, alginate spheres immobilization) under stress. Plants treated with the marine like leaf spraying encapsulation exhibited resilience terms of Kautsky curve intensity shape, indicating better photochemical apparatus function. These also facilitated post-stress recovery. Deep analysis revealed SynCom-induced improvements plant's apparatus, particularly PS II donor side. Moreover, it was possible observe that upon relief these two techniques, alongside inoculated throughout watering able recover profiles. Analysing Fv/Fm values, watering, beads spray can be considered heat-tolerant, a characteristic conserved sampling moments. Heat-wave exposure led an increase energy absorbed by non-inoculated as counteractive measure overcome low observed (low trapping transported fluxes). The reduction impact attributed SynCom's ACC-deaminase production, which lowered ethylene accumulation, growth photosynthetic efficiency. noted reduced dissipation relief, efficient mechanisms due application. Statistical models generated attained data allowed depicting fluorescence signatures each thermal inoculation treatment very high degree accuracy, reinforcing different treatments have fact impacts photochemistry but provide tool future assessments using proposed Alginate bead based release emerged efficient, scalable technique continuous benefits response.
