Effect of fire severity on physical and biochemical soil properties in Zagros oak (Quercus brantii Lindl.) forests in Iran

Effect of prescribed fire on soil properties and soil erosion in a Mediterranean mountain area

“…The direct and indirect effects of fire were often studied in soil surface (e.g., Arocena and Opio, 2003;Huseyin, 2006;Thomaz and Fachin, 2014;Meira-Castro et al, 2015;Armas-Herrera et al, 2016;Aznar et al, 2016), but some works showed that these effects reach deeper soil layers, at least down to 30 cm (Fonseca et al, 2011;Dennis et al, 2013;Heydari et al, 2017). The present work is in agreement with the results presented by the former authors, contributing to reinforce the idea that more attention should be given to the direct and indirect effects of fire at deeper depths.…”

“…The present work is in agreement with the results presented by the former authors, contributing to reinforce the idea that more attention should be given to the direct and indirect effects of fire at deeper depths. The variations observed in the chemical and physical properties of the first 20 cm topsoil can be related to the heating of the soil (Dennis et al, 2013) and the production of hydrophobic substances (e.g., Keizer et al, 2008), which in turn cause changes in the biological activity (e.g., Guerrero et al, 2005), hydraulic conductivity (e.g., Imeson et al, 1992;Fonseca et al, 2011), chemical transformations occurring in the soil (e.g., Heydari et al, 2017), and erosion and leaching processes (e.g., Cancelo-González et al, 2015). In the present study, soil permeability was high and very high in all measurement campaigns performed.…”

Hydrogeologic setting overrides any influence of wildfire on pore water dissolved organic carbon concentration and quality at a boreal fen

“…Although the magnitude of this increase is on a different scale to the increase at Poplar Fen, this indicates that there is still potentially a wider regional control on DOC dynamics, likely linked to meteorological conditions (Khadka et al, ). We did see an increase in electricial conductivity (EC) at Poplar Fen 1 year postfire (Table S1), which is to be expected given the large amount of ash/char in the system (Alauzis, Mazzarino, Raffaele, & Roselli, ; Hernández, Garcia, & Reinhardt, ; Heydari, Rostamy, Najafi, & Dey, ; Petrone et al, ). Therefore, although there was no clear effect of fire on DOC concentration at this site, we do see an impact on other environmental characteristics.…”

Rapid and economical protocols for genomic and metagenomic DNA extraction from oak (Quercus brantii Lindl.)

“…The genus Quercus is one of the most important clades of woody angiosperms in the northern hemisphere in terms of species diversity, ecological dominance, and economic value. This genus provides important economic benefits and high sociocultural value, and its role in water and soil protection in different regions of the world, such as Europe (e.g., UK, Slovakia, Czech Republic, Hungary, Austria, Germany, Italy, France, Ukraine, Belarus, and Moldova), North and Central America (e.g., USA, Mexico, Belize, Canada, Colombia, Guatemala, and El Salvador), and Asia (e.g., Iran and Indonesia), led to increasing attention to this genus (Nixon 2006;Heydari et al 2016). Quercus is the most frequent genus of the Fagaceae family in forests of Iran (Panahi et al 2012), and several species of oaks grow abundantly in Zagros forests in the west region of Iran.…”
