Kombiadou, K., Costas, S., Yang, Z., and Silvestri, S., 2023. Preliminary results for dune vegetation identification from high-resolution satellite imagery, EGU General Assembly 2023, Vienna, Austria, 24–28 Apr 2023, EGU23-15730

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 feedbacks between dune plants and coastal topography are fundamental to the self-organisation capacity of coastal dunes and a shift in community structure and composition (i.e., expansion of invasive species) can cause a domino effect, potentially crippling previously established system adaption mechanisms. It follows that monitoring dune vegetation is crucial, especially in protected areas and in fragmented and stressed dune environments. Even though recent improvements in spectral and spatial resolution of satellite imagery open new and exciting prospects for large-scale environmental monitoring, this potential is largely unused in dune ecogeomorphology, due to the challenges related with the small size and density of dune plants and the complexity and heterogeneity of the existing species. Machine learning techniques and subpixel classification methodologies, like the Random Forest Soft Classification (RFSC), have shown promising results in similarly challenging environments in terms of plant size and heterogeneity, with high accuracies in subpixel fractional abundance of marsh-vegetation species. Even though subpixel classification could improve monitoring biodiversity from satellite imagery, similar approaches have never been tested for dune environments. These challenges and gaps inspired the present work, built around the idea of testing subpixel classification methods for dune plant species identification using high-resolution satellite imagery. Here we present preliminary results from the application of RFSC to the western barrier of the Ria Formosa system (S. Portugal) using WorldView2 (2017) imagery and training/validation samples from UAV, along with the next steps planned to test the hypothesis that RFSC methods can be successfully used to identify dune plant species and to assess their predictive capacity and identify potential limitations.

Insights on Ecotoxicological Effects of Microplastics in Marine Ecosystems: The EPHEMARE Project

Francesco Regoli, Marina Albentosa, Carlo Giacomo Avio, Annika Batel, Maria João Bebianno, Marie-Laure Bégout, Ricardo Beiras, Juan Bellas, Ronny Blust, Agathe Bour, Thomas Braunbeck, Jérôme Cachot, Camilla Catarci Carteny, Bettie Cormier, Xavier Cousin, Alberto Cuesta, María Ángeles Esteban, Marco Faimali, Chiara Gambardella, Francesca Garaventa, Stefania Gorbi, Lúcia Guilhermino, Ketil Hylland, Steffen H. Keiter, Kathrin Kopke, Bénédicte Morin, Alexandre Pacheco, Lucia Pittura, Raewyn M. Town, Luis R. Vieira

The Ephemare project was supported in the period 2015–2018 by JPI Oceans, as one of 4 sister projects in the joint action on ecological aspects of microplastics. Ephemare investigated several issues concerning the ecotoxicological effects of microplastics (MPs) in marine organisms. Ephemare included 16 European Institutions from 10 Countries and was organized into seven, highly complementary Work Packages (WPs) with the aim to elucidate adsorption and release of chemicals to/from MPs, coupled with MP ingestion rates, translocation in different tissues, trophic transfer and egestion, potential toxicological effects and mechanisms of action, as well as real distributions of MPs in marine organisms from several European areas.
