Main research lines

horizontal rule

bullet
Forest ecophysiology. Application of stable isotopes (d13C and d18O) 
to understand the response of Mediterranean and temperate trees to climate, 
with special emphasis on their mechanisms to cope with drought: 

- To establish the role of stomatal control and other physiological 
	mechanisms in determining d13C and d18O 
	of wood and leaf material 

- To assess the potential as climate proxies of stable isotope studies 
	in tree-rings for Mediterranean species
bullet
Palaeoecology. Application of stable isotopes (d13C and d15N)  in 
 plant remains recovered from archaeological sites (see archaeobotany)
 as palaeoenvironmental tools:
  
 - To reconstruct water and nutrient status of ancient crops, 
  through the analysis of d13C and d15N in 
  archaeological grains (cereal and legumes) 
 
 - To determine the climatic background in which the crops were 
  developed, through the analysis of d13C of 
  archaeological wood charcoal
bullet
Crop ecophysiology and plant breeding. Study of the physiological 
basis and potential for selection purposes of different techniques: 

- stable isotopes (d13C, d15N and d18O) in cereal grains and leaves 

- Near Infrared Reflectance Spectroscopy (NIRS) of cereal grains 

- Visible and Near Infrared reflectance of cereal canopies

2007-2009. WETMISTFAGUS-Water Economy of beech in Temperate MIxed STands: Fading Away or Going on Under Stress?
Funding Source: Marie Curie Programme, European Union, 6th FP. MC-IEF-039418.
Responsible: Heinz Rennenberg (Univ. Freiburg, scientific in charge)
                        Juan Pedro Ferrio (Univ. Freiburg, researcher)

The aim of this project is to determine whether the ecophysiolofical traits of beech (Fagus sylvatica L.) can be a disadvantage respect some of its competitors (conifers and oaks) in an scenario of increasing temperatures and drought. The project combines information from stable isotopes (d13C and d18O) with sap flow measurements, in order to develop a method to integrate plant water balance from stable isotope data.

2006-2008. Diez mil años de interacción clima – agricultura en el Mediterráneo: Inferencias basadas en el análisis de restos arqueobotánicos agrícolas y forestales.
Funding Source: CICYT, Spanish Government. CGL2005-08175-C02-1/BOS.
Responsible: Jordi Voltas (UdL, co-ordinator), José Luis Araus (UB, subproject 2).

This project aims to characterise the reciprocal interaction between climate and early agricultural societies during the last ten millennia, both in the Fertile Crescent and the Iberian Levant.

2003-2006. From the adoption of agriculture to he current landscape, long-term interaction between men and environment in the East Mediterranean Basin (MENMED).
Funding Source: DG Research, European Union. Programme INCO-MED. ICA3-CT-2002-10022.
Responsible: Miquel Molist (UAB, co-ordinator), Jordi Voltas (UdL, partner 3).

The aim of this project was to understand the environmental and social context at the origins of agriculture in the Fertile Crescent, compared to the current conditions in the area, and combining historical, sociological and archaeological sources.

2002-2004. Reconstrucción de las condiciones ambientales de los 
cultivos al inicio de la agricultura, basada en el análisis de restos arqueológicos de cereales.
 Funding source: CICYT, Spanish Government. BTE2001-3421-C02-01.
Responsible: José Luis Araus (UB, co-ordinator), Jordi Voltas (UdL, subproject 2).

The project aimed to reconstruct the climatic and crop conditions at the origins of agriculture in the Fertile Crescent and North-East Iberian Peninsula through the study of stable isotopes in archaeological plant remains.
