Description of the joint DEMETRA-FO3REST LIFE project collaboration

The cooperation allowed more effective information and dissemination to public decision-makers, in particular with regard to biodiversity and air pollution. Ozone pollution is a serious cause of alteration of climate and damage to ecosystems. Ozone, in fact, is both a serious greenhouse gas and a strong oxidant gas. Concerning ozone risk assessment to vegetation, ozone uptake through the stomata - i.e. highly specialized micro-apertures by which plant leaves control gas exchanges (CO2, water, ozone) with the atmosphere – should be quantified. Rather, present risk assessment is based only on how much ozone is in the air. Especially in Mediterranean climates, water stress may restrict stomatal aperture and thus ozone uptake. A proper quantification of stomatal ozone uptake or flux can be carried out only when all the environmental variables affecting stomata are recorded.

FO3REST installed an Eddy-covariance tower in San Rossore Park, with the aim of measuring and parameterizing stomatal ozone fluxes. DEMETRA installed two monitoring stations in San Rossore Park for measuring all meteorological variables that can affect pollen dispersal and biodiversity. The evaluation of ozone impacts on pollen dispersal is truly innovative.

DEMETRA meteorological stations provided environmental variables that are needed for calculating the stomatal ozone fluxes in FO3REST.

The two projects have thus started specific activities for the fulfillment of those objectives. DEMETRA bought two slow-response ozone sensors for measuring the atmospheric concentrations of this pollutant. FO3REST measures gas exchanges of natural poplars present in the forest located in Fortino Nuovo (San Rossore) and in Massaciuccoli Lake, to derive a parameterization of how stomata respond to the environmental variables. The two ozone monitors were successfully installed at the DEMETRA meteorological stations.

Finally, DEMETRA determined the genetic characteristics of the plants where the stomatal conductance were measured by FO3REST.

Bioinformatics approaches allowed evaluating which genes are most important in ozone response and for adaptation at ozone stress. For this, DEMETRA beneficiaries (IGV-CNR FI and GESAAF) have enlarged the study area of forest with natural poplar. The number of poplar individuals to be analyzed by genomic approach was increased to 70. The combination of spatial genetic with ecophysiology is fundamental in study of Genetic Landscape which will permit to understand how the population will react in the next future to climatic change.

Replicability and transferability of the project activities to other European regions

Although the project has ended, several methods developed by the project are developing further in other projects. In the framework of the transferability of the results and innovative methodologies, planned during the project, in field campaigns were carried out at Antella and San Rossore in 2014 for stomatal conductance parameterization. For that, we bought a free-air ozone fumigation facility as an opportunity for stomatal ozone flux research on forests (see the financial Excel sheet). We stress on the "crucial necessity" to perform these measurements in order to calibrate and to validate the transfer function for a better transferability towards other region. This task, carried out for the good implementation of core experimental activities in FO3REST, will allow applying, testing, evaluating and validating standard (PODY) and thresholds (CLef).

The application of the method make a positive contribution to the convergence and policy leading up to the effectiveness of forest monitoring by providing a framework for research and analysis.
