“…Our results are in agreement with a large body of research on Mediterranean dry forests (de Román & Miguel, 2005, Martín-Pinto et al, 2006b, Buscardo et al, 2010, Hernández-Rodríguez et al, 2013 and specifically with some studies conducted also with P. pinaster (Buscardo et al, 2011, Gassibe et al, 2011, Sousa et al, 2011. Nonetheless, the overall evidence in this field cannot be considered as conclusive yet.…”

“…Wildfires constitute the main source of disturbance in Mediterranean forest ecosystems (Gassibe et al, 2011), strongly affecting soil fungi and plant communities (Dahlberg et al, 2001, Carney & Bastias, 2007, Rincón & Pueyo, 2010. This comes both as a direct result of the high temperatures reached during a forest fire, but also indirectly through changes to soil chemical and physical properties, like a pH increase, enhanced hydrophobicity or changes of available nutrients (Certini, 2005).…”

“…Many studies report large shifts in species abundances, decreases in diversity, large losses in ECM sporocarp production, and even complete loss of ectomycorrhizal species after severe fires (Grogan et al, 2000, Treseder et al, 2004, Martín-Pinto et al, 2006b, Gassibe et al, 2011. For example, Dahlberg et al (2001) stablished a link between different fire severities and survival of mycorrhizal flora, after four months of prescribed burning in a Scandinavian boreal forest.…”

“…P. pinaster is also an obligate mutualist with ectomycorrhizal fungi and normal growth does not occur without them (Smith & Read 1997, Read, 1998. Given its ecological relevance and intimate relationship between forest fires and fungi, P. pinaster has been the focus of several studies in Mediterranean areas on how does fire affect fungal communities, as seen by the decrease in richness, diversity and production of ECM sporocarps as a product of wildfires (Martín-Pinto et al, 2006b, Gassibe et al, 2011. Also several studies (Buscardo et al, 2010, Rincón & Pueyo 2010, Rincón et al 2014 have found that wildfires influence the structure of ectomycorrhizal fungal communities associated with P. pinaster, showing that some fungal groups are potentially fire-adapted (Rincón et al, 2014).…”

Aim of the study: Mycorrhizal fungi in Mediterranean forests play a key role in the complex process of recovery after wildfires. A broader understanding of an important pyrophytic species as Pinus pinaster and its fungal symbionts is thus necessary for forest restoration purposes. This study aims to assess the effects of ectomycorrhizal symbiosis on maritime pine seedlings and how fire severity affects fungal colonization ability.Area of study: Central Spain, in a Mediterranean region typically affected by wildfires dominated by Pinus pinaster, a species adapted to fire disturbance.Material and Methods: We studied P. pinaster root apexes from seedlings grown in soils collected one year after fire in undisturbed sites, sites moderately affected by fire and sites highly affected by fire. Natural ectomycorrhization was observed at the whole root system level as well as at two root vertical sections (0-10 cm and 10-20 cm). We also measured several morphometric traits (tap root length, shoot length, dry biomass of shoots and root/shoot ratio), which were used to test the influence of fire severity and soil chemistry upon them.Main results: Ectomycorrhizal colonization in undisturbed soils for total and separated root vertical sections was higher than in soils that had been affected by fire to some degree. Inversely, seedling vegetative size increased according to fire severity.Research highlights: Fire severity affected soil properties and mycorrhizal colonization one year after occurrence, thus affecting plant development. These findings can contribute to a better knowledge of the factors mediating successful establishment of P. pinaster in Mediterranean forests after wildfires.Keywords: Wildfire; mycorrhizal fungi; Maritime pine; bioassay.

“…Contrary to expectations, fungal richness found in these ecosystems was similar to or even higher than the number of taxa found in some studies of mature stands of different forest tree species. Gassibe et al (2011) reported 115 fungal taxa in a four-year study in a nearby P. pinaster Ait. mature stand.…”
