The project gives in consideration the innovative hypothesis that paleoenvironmental data obtained from the gypsum speleothems studies complete the historically ones which have been obtained by means of isotope analysis of carbonate speleothems. This assumption could be due to the fact that the deposit of gypsum is only related to evaporation processes in contrast with the CO2 content and outgasing which controls the carbonate speleothems deposits. Being true this assumption, Would the study of gypsum speleothems detect not well understood climatic periods like the limits of the last Dryas (Younger, Older ), also note the fact that such periods do not appear clearly defined by carbonate speleothems deposits.
Concisely, the present project intends to complete the paleoclimatic information from periods where the deposit of gypsum in caves was especially further on. To reach the objectives, we plan to sample speleothems (no more than 40 ka BP) in the gypsum Karst of Sorbas (Andalusia), The Cave of El Soplao (Cantabria) and the gypsum karst of Romagnolo Vein (Italy), both carbonated and gypsiferous following with a complete isotopic analysis of the samples.

Along with the global temperature rise, occuring as a consequence of the greenhouse effect, precipitation also exhibits spatio-temporal changes. Understanding the potential impacts that these changes would have on available water for ecosystems represents a challenge for environmental science. However, acquiring this knowledge is not an easy task, as the spatial relationship between productivity and precipitation differs from the temporal relationship between these two variables. These differences suggest the existence of environmental (biotic and abiotic) factors acting as controls of the temporal productivity response to changing moisture (e.g. temperature, lithology, vegetation structure, biogeochemical processes, and any other system factor that provides inertia or resistence). In the context of this project we will evaluate the response of primary productivity to changes in precipitation, considering the simultaneous constraints imposed by these other environmental factors. Because observed and predicted changes in precipitation include not only differences in total quantity, but also in temporal distribution (e.g. number of days with precipitation events, timing and size distribution of events, precipitation intensity), we will evaluate the response of primary productivity to total annual precipitation, as well as its intra- and inter-annual variability. Since an important limitation to studying the temporal dynamics of primary productivity is the absence of long-term datasets, primary productivity and its dynamics will be characterized by means of ecosystem functional attributes strongly related to primary productivity yet, derived from NOAA-AVHRR/LTDR, MODIS-TERRA and SPOT satellite images. Differences in temporal periods and spatial resolutions within these databases will allow us to analyze ecosystem responses for different spatial and temporal scales. Mediterranean ecosystems of the Iberian Peninsula represent an ideal study area for this research, not only because water is the main limiting factor and aridity increases have been predicted, but also because of the existence of strong environmental gradients (abiotic and biotic) within a relatively small area.

Global change impact on ecosystems is a major environmental challenge facing society in the XXI century. According to this challenge the research team aims to develop a monitoring and warning system to assess the impact of global change on ecosystems of SE Spain, an area particularly at risk given the high biodiversity values it holds and the exchange risk climate and land use facing. Such system is based on the anomalies detection in the ecosystem functioning and its relevance according to the conservation value and vulnerability of affected ecosystems. This system, also constitute support for the development of an early warning system, and it will involve the following tasks: 1) Identification of reference conditions and environmental controls of attributes descriptors of ecosystem functioning, 2) Analysis of the relationship between changes and trends in these attributes and the global change drivers for the different ecosystems, and 3) Diagnosis of the conservation value and vulnerability of ecosystems to climate change and land use changes. The project is based on the achievements of previous investigations in the application of remote sensing techniques and modeling to characterize the ecosystem functioning and the high knowledge accumulated by the research team about plant diversity distribution in the region. As a result, a on-line application will be developed to support decisions of managers.

GLOCHARID
The GLOCHARID project is a node of the Global Change Observatories Network of Andalusia, a platform launched by the Environmental Administration of this region. GLOCHARID aims to monitor the global change effects on arid and semi-arid ecosystems of Andalusia, and represents a meeting point for scientists and managers who work in these ecosystems. The main objective of GLOCHARID is to design and implement a Monitoring System based on environmental indicators able to detect the impact of global change on the natural systems and the socioeconomic sectors of the region. Such monitoring system and the collaborative work between scientists and managers will support an Adaptive Management approach to mitigate the impact on ecosystems, and the adaptation of the socio-ecological system to the environmental changes. GLOCHARID is integrated by 12 research groups from three universities (Universidad de Almería, Universidad de Granada and Universidad de Buenos Aires) and three research centres of the Consejo Superior de Investigaciones Científicas (CSIC) (Doñana Biological Station, Zaidín Experimental Station and Arid Zone Experimental Station), and managers of the Protected Area Network of Andalusia (RENPA).

- La composición isotópica para diferenciar entre procesos que contribuyan al flujo neto de CO2, incluyendo:
- Aire de la atmósfera, de los poros del suelo y de cavernas subterráneas.
- Agua del suelo, de cuevas y cursos de agua superficiales.
- Substratos orgánicos e inorgánicos, incluyendo muestras vegetales.
- El acoplamiento de modelos ecofisiológicos y geoquímicos para:
- Clarificar la contribución de los procesos geoquímicos al intercambio neto de CO2
- Estimar la importancia global de las fuentes y sumideros geoquímicos.
Todo esto nos permitirá abordar el objetivo principal del proyecto, conocer el papel de los procesos geoquímicos de disolución/precipitación de los carbonatos y discriminar entre los procesos bióticos y abióticos en el balance total de carbono
