“…In fact, the largest fires in the Mediterranean side of the IP seem to be associated with southeastern advections conducive to extreme heat waves (Rodrigues, Costafreda‐Aumedes, et al., 2019; Rodrigues, Jiménez‐Ruano, & de la Riva, 2019; Rodrigues, González‐Hidalgo, et al., 2019; Rodrigues et al., 2020). Likewise, fires are known to be concomitant with thermal anomalies in the northeastern end of the IP (Cardil et al., 2015; Duane and Brotons, 2018) or Sardinia and Corsica (Ager et al., 2014; Salis et al., 2021). Though weaker than NAO's, the WeMOI also exerts moderate influence in the Mediterranean rim of the IP.…”

This work explores the main climate teleconnections influencing the Western Mediterranean Basin to outline homogeneous fire‐prone weather domains combining cross‐correlation time series and cluster analysis. We found a zonal effect of the Scandinavian pattern over the entire region with an interesting alternation of phases from positive during winter‐spring (increased rainfall leading to fuel accumulation) to negative (dry conditions) modes during summer controlling burned area and fire size. The North Atlantic Oscillation (NAO) dominates the number of fires over the Iberian Peninsula (IP) while the Western Mediterranean Oscillation pattern modulates fire activity over the Mediterranean coast in the IP (linked to westerly winds), Southern France, Corsica and Sardinia (rainfall regulation). These distinctive influence traits resulted in three different domains splitting the IP into a Mediterranean rim along the coast (from southern Spain to southwestern France) and an inland and western region (Portugal plus western Spain); and a third in southeastern France, Corsica and Sardinia.

“…However, the area of Gennargentu where Eucera gennargentui was found is rather restricted and subject to disturbing factors due to strong grazing regimes and reckless reforestation that inexorably damage the grasslands where the endemic host plants live. The frequency of numerous fires that devastate natural ecosystems and rural areas in Sardinia (Capra et al 2018;Salis et al 2021) represents a further important threat to the diversity of flora and consequently of wild bees.…”

In this paper, an update of the species of the genus Eucera Scopoli, 1770, subgenus Tetralonia Spinola, 1838 from Sardinia is reported, based on data collection as well as on recent survey carried out at Gennargentu Massif. Seven species are recorded, four of which are newly added: Eucera fulvescens (Giraud, 1863), E. gennargentuisp. nov. Nobile, Catania & Bella, E. julliani (Pérez, 1879), and E. nana (Morawitz, 1873). The new species, Eucera (Tetralonia) gennargentui Nobile, Catania & Bella is described from the high altitude of Gennargentu Massif. Details on distributions, host plants, and other biological aspects are given for each species treated. The taxonomic comparison of the taxa belonging to the subgenus Tetralonia from Sardinia, including E. gennargentuisp. nov., are discussed taking into account both morphological and COI barcode sequences. An identification key to Eucera (Tetralonia) species from Sardinia is also provided.

“…The algorithm calculates a two-dimensional fire growth at a resolution set by the user by minimizing fire travel time from the cell corners based on Rothermel's fire spread model [63]. The MTT has been widely used in previous studies assessing wildfire transmission and fuel treatment effects in complex terrains worldwide [12,64,65]. The fire ignitions were first distributed within the modeling domain according to the ignition probability grid (Figure 3).…”

Despite the need for preserving the carbon pools in fire-prone southern European landscapes, emission reductions from wildfire risk mitigation are still poorly understood. In this study, we estimated expected carbon emissions and carbon credits from fuel management projects ongoing in Catalonia (Spain). The planning areas encompass about 1000 km2 and represent diverse fire regimes and Mediterranean forest ecosystems. We first modeled the burn probability assuming extreme weather conditions and historical fire ignition patterns. Stand-level wildfire exposure was then coupled with fuel consumption estimates to assess expected carbon emissions. Finally, we estimated treatment cost-efficiency and carbon credits for each fuel management plan. Landscape-scale average emissions ranged between 0.003 and 0.070 T CO2 year−1 ha−1. Fuel treatments in high emission hotspots attained reductions beyond 0.06 T CO2 year−1 per treated ha. Thus, implementing carbon credits could potentially finance up to 14% of the treatment implementation costs in high emission areas. We discuss how stand conditions, fire regimes, and treatment costs determine the treatment cost-efficiency and long-term carbon-sink capacity. Our work may serve as a preliminary step for developing a carbon-credit market and subsidizing wildfire risk management programs in low-revenue Mediterranean forest systems prone to extreme wildfires.
