Optimization and validation of a micro–QuEChERS method for phthalates detection...
Sambolino, Annalisa; Rodriguez, Marta; De la Fuente, Jesus; Arbelo, Manuel; Fernández, Antonio; Kaufmann, Manfred; Cordeiro, Nereida; Dinis, AnaIn this study, an innovative method was developed to detect and quantify phthalates in fresh cetacean blubber. An adaptation of the ammonium formate QuEChERS method was used and adapted as a micro-extraction for small quantities of samples. Significantly, this technique utilized minimal quantities of reagents and salts, with the additional implementation of rigorous Quality Assurance/Quality Control protocols t...
Assessing the presence of Pithomyces chartarum in pastureland using IoT sensors...
Ávila, Mariana; Pinelo, João; Casas, Enrique; Capinha, César; Pabst, Rebecca; Szczesniak, Iga; Domingues, Elizabeth; Pinto, Carlos; Santos, Valentina: Spores from the fungus Pithomyces chartarum are commonly found on Azorean pastures. When consumed by cattle along with the grass, these spores cause health issues in the cattle, resulting in animal suffering and financial losses. For approximately two years, we monitored meteorological parameters using weather stations and collected and analyzed grass samples in a laboratory to control for the presence of spo...
Trophic position of dolphins tracks recent changes in the pelagic ecosystem of ...
Bode, Antonio; Saavedra, Camilo; Álvarez-González, Miguel; Arregui, Marina; Arbelo, Manuel; Fernández, Antonio; Freitas, Luís; Silva, Mónica A.Dolphins play a key role in marine food webs as predators of mid-trophic-level consumers. Because of their mobility and relatively long life span, they can be used as indicators of large-scale changes in the ecosystem. In this study, we calculated the trophic position (TP) of 5 dolphin species from the Canary, Madeira and Azores Islands using bulk and compound-specific stable isotope ratios from muscle tissue t...
Mapping and assessing ecosystem services in Europe's Overseas : A comparative a...
Sieber, Ina M.; Montero-Hidalgo, Miriam; Kato-Huerta, Jarumi; Rendon, Paula; Santos-Martín, Fernando; Geneletti, Davide; Gil, Artur José FreireMapping and Assessment of Ecosystems and their Services (MAES) has been widely applied on the European Union (EU) mainland, whereas the EU Overseas entities still bear potential for implementation. This paper presents novel applications of the MAES procedure in the EU Outermost Regions and Overseas Countries and Territories ("EU Overseas"). Eight case studies from different geographical areas were analysed thro...
Macroalgae niche modelling : a two-step approach using remote sensing and in si...
Casas, Enrique; Fernandez, Marc; Gil, Artur José Freire; Yesson, Chris; Prestes, Afonso L.; Moreu‐Badia, Ignacio; Neto, Ana I.; Arbelo, ManuelWe are facing a global loss of biodiversity due to climate change. This will lead to unpredictable changes in ecosystems, affecting the goods and services they provide introduction of non-indigenous marine species. This represents one of the major threats to marine biodiversity and therefore, there is a strong need to assess, map and monitor these alien species. The appearance of non-indigenous species is espec...
