“…Soil microbial community plays a key role in terrestrial ecosystems, by being involved in several ecosystem services. Indeed, it provides supporting services (soil formation, nutrient cycling, and plant growth), as well as regulating services (i.e., climate and gas regulation, C sequestration, water purification, disease and pest regulation, and bioremediation) and provisioning ones (i.e., the supply of food, fiber, fuel, genetic resources, chemicals, and pharmaceuticals) [1][2][3].…”

Microbial diversity plays a crucial role in ecosystem processes, including organic matter decomposition and nutrient cycling. This research explores the effect of prescribed burning (PB) on soil microbial diversity, as well as biomass and activity in Mediterranean pine plantations. In burned and adjacent unburned plots of Pinus pinea and P. pinaster plantations of Southern Italy protected areas, the fermentation layer and the 5 cm thick layer of mineral soil underneath were sampled at intervals during the first year after PB. The experimental protocol encompassed measurements of total microbial abundance (Cmic and soil DNA), fungal mycelium, fungal fraction of Cmic, microbial activity, bacterial genetic diversity (16S rDNA PCR-DGGE), microbial metabolic quotient (qCO2), and C mineralization rate (CMR), as well as physical and chemical soil properties. PB caused only temporary (up to 3 h–32 d) reductions in Cmic, DNA amount, fungal mycelium, respiration, and CMR in the P. pinaster plantation, and had no appreciable negative effect on the microbial community in P. pinea plantation, where fire intensity was lower because of less abundant litter fuel. In either plantation, PB did not generally reduce bacterial genetic diversity (evaluated as band richness, Shannon index, and evenness), thus, also accounting for the fast recovery in microbial growth and activity after high-intensity PB in P. pinaster plantation. While confirming PB as a sustainable practice to reduce wildfire risk, also supported by data on plant community obtained in the same plantations, the results suggest that an integrated analysis of microbial diversity, growth, and activity is essential for an accurate description of PB effects on soil microbial communities.

“…Soil salinity negatively impacts agricultural production and leads to changes in microbial community composition and activity [ 6 ]. Microorganisms are central to biogeochemical cycles and thus play essential roles in the provision of soil services [ 7 ]. Despite the economic, environmental, and nutritional consequences of the increasing rate of soil salinization, microbial biodiversity studies of saline soils are scarce [ 8 ].…”

Hypersaline environments encompass aquatic and terrestrial habitats. While only a limited number of studies on the microbial diversity of saline soils have been carried out, hypersaline lakes and marine salterns have been thoroughly investigated, resulting in an aquatic-biased knowledge about life in hypersaline environments. To improve our understanding of the assemblage of microbes thriving in saline soils, we assessed the phylogenetic diversity and metabolic potential of the prokaryotic community of two hypersaline soils (with electrical conductivities of ~24 and 55 dS/m) from the Odiel saltmarshes (Spain) by metagenomics. Comparative analysis of these soil databases with available datasets from salterns ponds allowed further identification of unique and shared traits of microbial communities dwelling in these habitats. Saline soils harbored a more diverse prokaryotic community and, in contrast to their aquatic counterparts, contained sequences related to both known halophiles and groups without known halophilic or halotolerant representatives, which reflects the physical heterogeneity of the soil matrix. Our results suggest that Haloquadratum and certain Balneolaeota members may preferentially thrive in aquatic or terrestrial habitats, respectively, while haloarchaea, nanohaloarchaea and Salinibacter may be similarly adapted to both environments. We reconstructed 4 draft genomes related to Bacteroidetes, Balneolaeota and Halobacteria and appraised their metabolism, osmoadaptation strategies and ecology. This study greatly improves the current understanding of saline soils microbiota.

“…La conservación de la materia orgánica del suelo es la base para formar agregados más grandes y resistentes a la erosión por su efecto cementante, al tiempo que nutre la vida edáfica y contribuye de forma vital con su fertilidad. La fertilidad del suelo se ve favorecida por la productividad primaria y el reciclado de nutrientes (Martín-López et al, 2012), así como la actividad microbiana del suelo, que es de vital importancia para el proceso de reciclado de nutrientes y cuya interacción con las plantas está estrechamente ligada, al ser considerados indicadores biológicos de la calidad del suelo (Saccá et al, 2017). Por lo tanto, la conservación de la materia orgánica es vital para mantener un suelo bien agregado y más resistente a la erosión (erodabilidad) (Franzluebbers, 2002).…”

“…Por otro lado, suelos erosionados son pobres en nutrientes debido a las pérdidas de las partículas de suelo, la mate-ria orgánica y la lixiviación o el agotamiento de los nutrientes . Adicionalmente, los procesos de erosión del suelo causan un fuerte deterioro en la prestación de los servicios ecosistémicos que el suelo ofrece y en las comunidades que lo usan para sus actividades productivas (Dossman et al, 2009), especialmente si el suelo va acompañado de características físicas, químicas y biológicas deficientes (Castro-Romero et al, 2014;Saccá et al, 2017).…”

Las funciones del suelo dependen de una serie de propiedades físicas químicas y biológicas, que combinadas determinan las cualidades esenciales del suelo. Estas cualidades a su vez garantizan que el suelo pueda cumplir sus roles ecológicos y productivos, y en consecuencia beneficiar la preservación de la vida en el planeta (Brammer & Nachtergaele, 2015); por lo tanto, el uso y manejo sustentable del suelo permite convivir en conexión con sus atributos y disfrutar de forma armónica de sus vitales servicios. Contrario a lo deseable, el suelo ha sufrido una alteración antrópica desmedida sin considerar las consecuencias. Estudios a nivel global han identificado que los cambios en el uso de la tierra durante los últimos 50 años por áreas para la agricultura y la ganadería, han generado alteraciones en la abundancia, composición y actividad de las comunidades microbianas, afectando la disponibilidad de nutrientes del suelo y la productividad de las plantas, además de deteriorar el ambiente y disminuir la calidad de vida de las personas (Soka & Ritchie, 2014; Ruiz et al., 2015).
