Other · May 15, 2025 Forecasting the temporal and spatial evolution of coastal wetlands is a complex and challenging endeavour, further complicated by shifting climatic conditions. From a coastal management perspective, however, it remains essential to anticipate local ... Full text Cite

The diverse influence of halophyte species on carbon sequestration capacity in salt-marshes

Other · January 20, 2025 As an ecosystem of high socioeconomic and ecological importance, global loss and degradation of salt-marshes has multifaceted detrimental impacts. Salt-marshes are recognised as blue carbon ecosystems and play a notable role in the global carbon cy ... Full text Cite

Subpixel classification of high-resolution satellite images to identify dune plants

Other · January 20, 2025 The increase in spectral and spatial resolution offered by satellite imagery opens new opportunities in ecosystem monitoring over broader scales. Combined with advances in machine learning algorithms, like the spectral unmixing methods, it is possi ... Full text Cite

Mapping Italian Alpine Peatlands Using Multisource Satellite Imagery and Machine Learning Approach

Other · January 20, 2025 While we are aware that the Italian Alps host thousands of small peatlands, the precise estimate remains uncertain due to the absence of a comprehensive map. These ecosystems are extremely valuable because, in addition to storing large amounts of o ... Full text Cite

Unmixing halophytes in coastal wetlands using a multi-sensor approach at two spatial scales

Other · January 20, 2025 Coastal wetlands are geomorphic systems highly sensitive to shifts in environmental forcings such as variations in fluvial sediment transport rates, sea level rise, subsidence rates, nutrient concentrations, temperature, and atmospheric CO2 levels. ... Full text Cite

Water surface temperature and salinity estimation from EO satellites for estuarine dynamics assessment in the Mediterranean and Black Sea

Other · January 20, 2025 Estuaries are known as transition zones which modulate the freshwater inputs into the sea, with ocean salt water entering the river mouth and merging with the zero-salinity river streamflow. Understanding their dynamics is important for several pur ... Full text Cite

A multi-sensor approach to the study of geomorphic, vegetation and hydrogeologic patterns of Alpine peatlands

Other · May 15, 2023 Geomorphic and vegetation patterns within peatlands are strictly related, and reflect the interactions among topography, hydrogeology, and climate. Vegetation patterns are closely related to soil moisture, drainage patterns, bulk density and carbon ... Full text Cite

Remote sensing salt marsh biomass: a dialogue between technical approach and spatial patterns of ecogeomorphological complexity

Other · May 15, 2023 Salt marshes provide a multitude of ecosystem services while simultaneously being susceptible to habitat loss and degradation in response to climatic and anthropogenic disturbances. Thus, the spatially explicit characterisation, monitoring and sust ... Full text Cite

Preliminary results for dune vegetation identification from high-resolution satellite imagery

Other · May 15, 2023 Coastal dunes are important habitats that provide a variety of ecosystem services (ecological, economic, coastal protection, etc.) and, as such, their monitoring is a priority for environmental protection (i.e., EU Directives). Eco-geomorphologic f ... Full text Cite

The vegetation-elevation relationship in salt marshes

Other · March 28, 2022 <p>Salt marshes are coastal ecosystems of high importance from ecological and geomorphological perspectives which have been disappearing fastin thelast centuries. Halophytic vegetation can support marsh survival through complex ecomor ... Full text Cite

High frequency spatio-temporal dynamics of seagrass meadows in a mediterranean lagoon

Other · March 28, 2022 <p>Seagrass meadows are a famously productive habitat found globally in intertidal and shallow subtidal shelves, hosting a rich biodiversity and efficiently sequestering carbon. They also exert an influence on coastal morphodynamics b ... Full text Cite

Saltmarsh vegetation biomass distribution from drones: a case study

Other · March 27, 2022 <p>Coastal salt marshes are unique and complex geomorphological systems, which must accrete to keep pace with sea-level rise. Even though we know the importance of vegetation and organic matter accumulation in the marsh accretion proc ... Full text Cite

Characterizing Alpine peatlands from drones: a case study 

Other · March 27, 2022 <p>Alpine peatlands occur in alpine, sub-alpine and mountain regions of the world and can be frequently found on the Alps as well as on the Andes, on the Tibetan Plateau, on the Australian Alps and in other regions of the world. Itali ... Full text Cite

Exploring the driving factors of CH4 and CO2 emissions in coastal wetlands: a case study in the Ravenna Province, Italy

Other · March 27, 2022 <p>Coastal wetlands play a strategic role in the context of mitigating climate-change thanks to their ability of sequestering large amounts of organic carbon (C) and store it in the ground. However, methane (CH4) may form in the sedim ... Full text Cite
