[{"publisher":"Wiley","intvolume":"        14","abstract":[{"text":"Vegetation establishment, growth and succession in riparian ecosystems are linked to river flow dynamics and groundwater table fluctuations. This is especially true in Alpine gravel-bed rivers with wide floodplains, geomorphically active floods and a strong river-aquifer exchange. The role of short-term groundwater fluctuations is not always clear in these ecosystems, as it is assumed that phreatophytic vegetation close to rivers is adapted to such conditions. Here, we provide data evidence of riparian plant response to short-term groundwater table fluctuations in a braided gravel-bed river (Maggia). We used indirect physiological variables for photosynthesis and transpiration—stomatal conductance gs and daily variation in stem diameter ΔDd—which we measured at six mature riparian trees of the Salicaceae family at two sites with different mean depths to groundwater during two growing seasons. The data demonstrate that (a) short-term variation of the groundwater table affects riparian vegetation—at the site with deeper groundwater, the water table depth was the best predictor of gs variability, while at the site with shallower groundwater, temperature and vapour pressure deficit (VPD) were the best predictors of ΔDd variability; (b) instantaneous stomatal conductance is related to VPD, but conditioned by groundwater levels, with higher stomatal conductance for the same radiative input and VPD when the water table was higher for all trees; and (c) local microclimate measured at tree locations had a stronger predictive power for gs than valley scale climate, suggesting local climate controls on vegetated stands on gravel bars. Our results provide evidence of riparian trees undertaking physiological adjustments to transpiration in response to groundwater stage, depending on their riparian floodplain setting.","lang":"eng"}],"quality_controlled":"1","date_published":"2021-03-01T00:00:00Z","publication":"Ecohydrology","article_processing_charge":"No","extern":"1","year":"2021","author":[{"last_name":"Martinetti","first_name":"Stefano","full_name":"Martinetti, Stefano"},{"full_name":"Fatichi, Simone","first_name":"Simone","last_name":"Fatichi","id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6"},{"full_name":"Floriancic, Marius","first_name":"Marius","last_name":"Floriancic"},{"first_name":"Paolo","full_name":"Burlando, Paolo","last_name":"Burlando"},{"first_name":"Peter","full_name":"Molnar, Peter","last_name":"Molnar"}],"date_updated":"2026-07-30T08:46:20Z","volume":14,"type":"journal_article","scopus_import":"1","article_type":"original","language":[{"iso":"eng"}],"doi":"10.1002/eco.2264","month":"03","issue":"2","publication_identifier":{"issn":["1936-0584"],"eissn":["1936-0592"]},"date_created":"2026-07-27T12:30:23Z","das_tickbox":"1","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Martinetti S, Fatichi S, Floriancic M, Burlando P, Molnar P. 2021.

Projecting the response of these ecosystems to climate change is thus crucial, but also uncertain due to complex interactions between topography, climate, and vegetation. Here, we performed numerical simulations in a real and a synthetic spatial domain covering a range of contrasting climatic conditions and vegetation characteristics representative of the European Alps. Simulations were run with the mechanistic ecohydrological model Tethys–Chloris to quantify the drivers of ecosystem functioning and to explore the vulnerability of Alpine ecosystems to climate change. We correlated the spatial distribution of ecohydrological responses with that of meteorological and topographic attributes and computed spatially explicit sensitivities of net primary productivity, transpiration, and snow cover to air temperature, radiation, and water availability. We also quantified how the variance in several ecohydrological processes, such as transpiration, quickly diminishes with increasing spatial aggregation, which highlights the importance of fine spatial resolution for resolving patterns in complex topographies. We conducted controlled numerical experiments in the synthetic domain to disentangle the effect of catchment orientation on ecohydrological variables, such as streamflow. Our results support previous studies reporting an altitude threshold below which Alpine ecosystems are water‐limited in the drier inner‐Alpine valleys and confirm that the wetter areas are temperature‐limited. High‐resolution simulations of mountainous areas can improve our understanding of ecosystem functioning across spatial scales. They can also locate the areas that are the most vulnerable to climate change and guide future measurement campaigns."}],"quality_controlled":"1","publication":"Ecohydrology","date_published":"2019-01-01T00:00:00Z","extern":"1","article_processing_charge":"No","author":[{"last_name":"Mastrotheodoros","first_name":"Theodoros","full_name":"Mastrotheodoros, Theodoros"},{"full_name":"Pappas, Christoforos","first_name":"Christoforos","last_name":"Pappas"},{"last_name":"Molnar","first_name":"Peter","full_name":"Molnar, Peter"},{"first_name":"Paolo","full_name":"Burlando, Paolo","last_name":"Burlando"},{"last_name":"Hadjidoukas","full_name":"Hadjidoukas, Panagiotis","first_name":"Panagiotis"},{"id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","last_name":"Fatichi","first_name":"Simone","full_name":"Fatichi, Simone"}],"date_updated":"2026-08-06T07:44:22Z","year":"2019","volume":12,"type":"journal_article","scopus_import":"1","language":[{"iso":"eng"}],"doi":"10.1002/eco.2054","article_type":"original","month":"01","issue":"1","das_tickbox":"1","status":"public","publication_identifier":{"issn":["1936-0584"],"eissn":["1936-0592"]},"date_created":"2026-07-27T12:30:24Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["Alpine ecohydrology","Climate change","Ecosystem sensitivity","Numerical modelling","Spatialheterogeneity"],"citation":{"ista":"Mastrotheodoros T, Pappas C, Molnar P, Burlando P, Hadjidoukas P, Fatichi S. 2019.
