For extraction samples are placed into the refrigerator for 24 h. Samples are disrupted with an ultrasonic bath. Extracts are clarified using 0.2-μm, PTFE, HPLC syringe cartridge filters fitted with glass fiber prefilters. Analysis with HPLC system. Part of the extract was taken for the spectrophotometric analysis. Absorption was measure at 750, 665, 664, 647 and 630 nm wavelenght. Chlorophyll-a (Chl-a, uncorrected for pheopigments) was estimated using the trichromatic method of Jeffrey and Humphrey (1975). To obtain Chl-a corrected for pheopigments, as well as pheopigment concentrations, the extracts were measured before and after acidification with 1 N HCl, following the procedure of Lorenzen (1967).

Therefore, assessing the current extent and state of European wetlands, their current and potential greenhouse gases (GHG) profile and their medium to long-term mitigation capacity through restoration, or other measures, are key priorities of the European Union to tackle climate change. Led by the University of Aveiro, the Horizon project RESTORE4Cs (Modelling RESTORation of wEtlands for Carbon pathways, Climate Change mitigation and adaptation, ecosystem services, and biodiversity, Co-benefits) will assess the role of restoration action on wetlands capacity in terms of climate change mitigation and a wide range of ecosystem services using an integrative socio-ecological systems approach.
