The rhizosphere microbiome of burned holm-oak: potential role of the genus Arthrobacter in the recovery of burned soils

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 6 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data

El cambio global es un hecho constatado e incuestionable. Además de los procesos de tipo industrial existen otros factores, como los incendios forestales, que también contribuyen al calentamiento global dada la alta emisión de CO2 que producen. Disminuir la concentración de CO2 atmosférico, evitar su incremento o ayudar a su acumulación en la materia orgánica del suelo, se puede ver beneficiado por un correcto manejo del monte mediterráneo. Una rápida re-vegetación o recuperación de las formaciones autóctonas como son los encinares y robledales (Quercus ilex sp. rotundifolia y Q. pyrenaica) pueden ayudar en este sentido. Conocer las posibles etapas de modificación de estos bosques, expansión o regresión, por efecto del cambio climático también es importante, sobre todo si podemos contribuir a la progresión y al establecimiento de una mayor superficie de bosque. Los microorganismos del suelo son los responsables del cierre del ciclo biogeoquímico del carbono, contribuyendo además a la fertilidad del suelo y a la promoción del crecimiento vegetal. Por tanto en este proyecto se propone, la identificación de microorganismos indicadores que nos permitan seguir la evolución de la recuperación después de un incendio, la transición robledal-encinar y la progresión del robledal, como medida del cambio climático. Para ello se proponen los siguientes objetivos específicos: i) Análisis del fingerprint genético mediante TGGE de la diversidad microbiana y la redundancia funcional de fijación de N2 en los suelos bajo robles maduros y en progresión en alturas superiores. ii) Construcción y análisis de metagenomas de los suelos de encinar y robledal. iii) Secuenciación masiva del ADN ambiental extraído de un encinar y de un robledal maduros para la identificación de bioindicadores. iv) Monitorización, a los 2 y 4 años, de la evolución del encinar quemado y del robledal en progresión en altura mediante el empleo de los bioindicadores seleccionados.

Sampling Methods

Three sampling plots were randomly chosen within each study site along transects of 1.0 km length. At the BOF and UOF sites, we sampled the rhizosphere of three trees per plot, each with a diameter of at least 15 cm at breast height and separated by at least 5 m. Sampling took place on April 29, 2008 (3 years after the wildfire). Both sites were on a south-facing steep slope. The rhizospheric samples were collected from from holm oak rhizosphere soils by following the tree’s main roots until young cork-free roots were found at a distance of less than 50 cm from the trunk. The soil attached to the roots was manually removed and the roots with rhizospheric soil were put into 50 ml Falcon tubes filled with 20 ml of sterilized NaCl 0.8%. After shaking 25 min at 150 rpm and room temperature, the roots were removed and the tubes were centrifuged at 12,850 g for 5 min. The pelleted soil was used to extract environmental DNA. On the other hand, we processed up to 2 kg of soil from each site, sieved through a 2 mm mesh, for physicochemical analysis including soil type, pH, available water, total nitrogen, organic matter, electrical conductivity, etc. All these analyses were carried out with standardized procedures at the Food and Agriculture Laboratory of the Andalusian regional government at Atarfe (Granada, Spain).
