Cistus ladanifer metal uptake and physiological performance in biochar amended ...
Duarte, Bernardo; Pires, Vanessa; Carreiras, João; Carvalho, Ricardo Cruz de; Pereira, Manuel F.C.; Maurício, António M.; Martins-Dias, SuseteBiochar amendments are known to have a considerable influence on phytoremediation processes. Considering this, in the present work, we aimed to evaluate the effect of biochar amendments in metal-contaminated mine soils focusing on the metal uptake by Cistus ladanifer and its physiological consequences. Plants were exposed to mine soils with different biochar supplementations and the plant's physiological perfor...
In the trail of “Maçã de Alcobaça” protected geographical indication (PGI): Mul...
Duarte, Bernardo; Melo, Juliana; Mamede, Renato; Carreiras, João; Figueiredo, Andreia; Fonseca, Vanessa F.; de Sousa, Miguel Leão; Silva, Anabela B.Food fraud associated with the intentional mislabelling of non-Protected Geographical Indication (PGI) is a concern for consumers. “Maçã de Alcobaça” (Alcobaça apple) is one of the oldest Portuguese PGI products, characteristic of the main apple-growing regions in the country, being of utmost importance to develop traceability and authenticity tools to depict the PGI certification status of these products. Pulp...
Pervasive gaps in Amazonian ecological research
Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, JackBiodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...
Potential of Asparagopsis armata as a biopesticide for weed control under an in...
Duarte, Bernardo; Carreiras, João; Feijão, Eduardo; Carvalho, Ricardo Cruz de; Matos, Ana Rita; Fonseca, Vanessa F.; Novais, Sara C.; Lemos, Marco F. L.Marine macroalgae have been increasingly targeted as a source of bioactive compounds to be used in several areas, such as biopesticides. When harvesting invasive species, such as Asparagopsis armata, for this purpose, there is a two-folded opportunity: acquiring these biomolecules from a low-cost resource and controlling its spreading and impacts. The secondary metabolites in this seaweed’s exudate have been sh...
Halophyte fatty acids as biomarkers of anthropogenic-driven contamination in Me...
Duarte, Bernardo; Carreiras, João; Pérez-Romero, Jesús Alberto; Mateos-Naranjo, Enrique; Redondo-Gómez, Susana; Matos, Ana Rita; Marques, J. C.Estuarine environments are extremely affected by anthropogenic-driven contamination, namely heavy metals. In the recent years, several organisms have been studied to be used as sentinel species providing a wide range of biomarkers for estuarine contamination. Only recently non-traditional biomarkers, such as fatty acids, were included in animal ecotoxicology and impact assessment studies. Nevertheless, there is...
Spectral characterisation and discrimination of burnt areas
Pereira, José; Sá, Ana; Sousa, Adélia; Santos, Teresa; Carreiras, JoãoSpectral properties of recent burns charaterised, in the visible, near infrared, mid-infrared, thermal infrared, and microwave spectral domains. Fire-induced reflectance changes are also compared for varios ecosystems and biomes, and discussed in terms of the cological effects of phytomass combustion. The spectral signaturess of combustion products and of burnt areas are compared with those of various plant mat...
