Project Data

The project SUMHAL aims at implementing a strategy for biodiversity conservation in the Mediterranean area by setting a technologically efficient and scientifically robust system. The project combines fieldwork and virtual research environments for the recording, storing, analysis, and dissemination of the conservation status and threats of biodiversity in Andalusia (Southern Spain).

Title Sustainability for Mediterranean Hotspots in Andalusia integrating LifeWatch ERIC (SUMHAL). Working package 7: Improving sustainability of Mediterranean forests and silvopastoral agrosystems under climate change
Identifier LWE2021-03-025
Funding This study was funded by MICINN through European Regional Development Fund [SUMHAL, LIFEWATCH-2019-09-CSIC-13, POPE 2014-2020] and by the Spanish Ministry of Economy, Industry and Competitiveness [AGL2015-66048-C2-1-R; RTI2018-098015-B-I00].
Study Area Description The area under study in this work is located in Sierra de Oria (Almeria, Southeast Spain). This area is covered by a pine forest (dominated by Pinus pinaster and Pinus halepensis individuals) which is severly affected by intense and severe droughts. This Mediterranean area could serve as a mirror of the future climate events.
Design Description We aim to improve our understanding of the response of the Mediterranean forests to the main threats related to climate change. The specific aims of this working package were: 1) To explore the role of root microbiota in the decline process of Andalusian pine forests. 2) To disseminate and transfer knowledge to environmental managers and academia.

Sampling Methods

18 Pinus pinaster trees separated al least 50 m each other were selected in the forest of Sierra de Oria. The soil closely attached to the roots (rhizosphere) was collected. Sampling was performed on July 18, 2017 (summer samples) and on April 24, 2018 (spring samples). The main roots of each tree were followed until young roots were found at a distance of less than 50 cm from the trunk (5-25 cm in depth). The soil closely attached to the roots (rhizosphere soil) was collected manually by rubbing the roots, and 2 g of each rhizosphere soil were mixed with 5 mL of LifeGuard™ Soil Preservation Solution. Samples were kept at 4 ºC until they were processed. Additional samples of soil near the roots (500 g of soil per tree) were also collected to analyze physicochemical properties, solely on July 2017. The determination of soil physicochemical parameters was performed at the Agri-Food Laboratory of the Andalusian Regional Government (Granada, Spain) under the standardized procedures developed by this service. From each rhizosphere soil sample, the total DNA and RNA were extracted by using by using the RNA PowerSoil® Total RNA Isolation Kit and the RNA PowerSoil® DNA Elution Accesory kit. The extracted RNA was retrotranscribed to double stranted cDNA. Thus, 18 samples of cDNA were obtained in summer (C17-01 to C17-18), 18 in spring (C18-01 to C18-18), and 18 samples of DNA were obtained for summer (D17-01 to D17-18) and for spring (D18-01 to D18-18).

Study Extent The data were collected in Sierra de Oria (Almería, Southeast Spain, coordinates: 37°31′ N 2° 21′W). The place is covered by a natural population dominated by Pinus pinaster and Pinus halepensis trees, which is under the effect of severe and frequent droughts. Data were collected twice: on July 18, 2017 (summer samples) and on April 24, 2018 (spring samples). The mean temperature and precipitation in June and July (2017) are 23.9 °C and 1.6 mm, and means values in March and April (2018) of 12.1 °C and 26.5 mm, respectively.
