Research interests

Despite their key ecological value, coastal ecosystems such as seagrass meadows are experiencing a progressive decline, due to a number of threats associated to human activities along the coastline, as well as current climate changes. Investigation of the effects of climate and non-climate stressors on seagrasses became crucial, in order to determine both the physiological response, and the potential adaptive response of the species. Effects of single environmental stressors have been extensively studied in different seagrass species, both in natural and controlled conditions. Nonetheless, in natural environments, those stressors often do not act in isolation, but additive, synergistic or antagonistic effects occur.
In view of the above, my PhD project aims to investigate the effects of "multiple stressors" in seagrasses. The combined effects of pairs of factors (e.g. temperature vs. light; temperature vs. CO2 and light vs. CO2) are investigated looking at the expression of target genes by RT-qPCR. The photophysiological response is assessed looking at changes in the pigmentary pool, as well as characterizing the functionality and structure of the photosynthetic apparatus through chlorophyll a fluorescence measures. Changes in the morphology of the plants are considered, as well as changes in some plant fitness traits.
Project results will be useful for designing new management strategies of coastal resources allowing to move away from the impact-by-impact framework, to which management processes are strongly focused and providing new generation of early warning indicators for environmental assessment.
