Metals from human activities in a coastal Lagoon Saltmarsh - Sediment toxicity ...
Silva, Manuela; Aníbal, Jaime; Duarte, D. N.; Veloso, N.; Patrício, F.; Chicharo, LuisAnthropogenic pressure on coastal areas has been increasing in the last decades, threating the saltmarshes and the ecosystem services they provide. Sarcocornia fruticosa can have an important role in sequestration of metals from human activities. This study evaluated the effect of metal toxicity in saltmarsh sediment (measured by Ecological Risk Index-ERI) on S. fruticosa ability to metal (Cd, Cr, Ni, Pb and Zn...
Importância das plantas do sapal para reter os metais que chegam à Ria Formosa ...
Silva, Manuela; Duarte, D. N.; Chicharo, LuisOs sapais são ecossistemas costeiros, na transição entre a terra e o mar, que se caracterizam por ser colonizados por plantas vasculares superiores, herbáceas e arbustivas, que apresentam grande resistência à salinidade, e que por isso se designam de halófitas. Estas plantas desenvolveram ao longo do tempo estratégias de adaptação, que lhes permitem resistir a períodos de submersão, mais ou menos longos, consoa...
Understanding paleolithic human coastal adaptations in southwetern Iberian Peni...
Marreiros, Joao; Duarte, D. N.; Regala, Frederico; Dores, Tiago; Francisco, Rui; Soares, RicardoThe geological and geomorphological formations in the Atlantic shore of Southern Portugal in Algarve are characterized by karstic formations. Karstic features, such as natural caves and shelters, have long been seen as an attractive ecological and geological landscape to early human occupation during the Pleistocene and Early Holocene. The project PaleoCoast, Paleolithic Human Coastal Adaptations in Southwester...
Integrated approach to assess ecosystem health in harbor areas
Bebianno, Maria João; Pereira, C.; Rey, F.; Cravo, Alexandra; Duarte, D. N.; D'Errico, G.; Regoli, F.Harbors are critical environments with strategic economic importance but with potential environmental impact: health assessment criteria are a key issue. An ecosystem health status approach was carried out in Portimão harbor as a case-study. Priority and specific chemical levels in sediments along with their bioavailability in mussels, bioassays and a wide array of biomarkers were integrated in a biomarker inde...
