Stream sediment analysis for Lithium (Li) exploration in the Douro region (Port...
Cardoso-Fernandes, J; Lima, J; Alexandre Lima; Roda-Robles, E; Kohler, M; Schaefer, S; Barth, A; Knobloch, A; Goncalves, MA; Goncalves, F; Ana TeodoroLithium (Li) was recently added to the list of critical raw materials by the European Union due to its significance for the green energy transition. Thus, the development of new toolchains to make Li exploration more economic and more effective is needed. Stream sediment analysis can play an important part in these new tool chains. In this work, two historical stream sediment datasets covering parts of the Freg...
An in situ toxicity assay with the local phytoplankton community
Moreira-Santos, M; Antunes, SC; Goncalves, F; Soares, AMVM; Ribeiro, RThe present study describes an approach for toxicity estimates based on the in situ exposure of the local phytoplankton community immobilized in calcium alginate beads The assay was deployed in an acid mine drainage-impacted system at a reference site and an impacted site Abundances and growth rates of major taxonomic groups (green algae flagellates diatoms and cyanobacteria) and of the entire community were me...
Short-term dynamics of cladocerans in a eutrophic shallow lake during a shift i...
Abrantes, N; Nogueira, A; Goncalves, FThe changes in the dynamics of cladocerans in Lake Vela (Portugal), as well as the morphologic and life history traits of the small-bodied cladoceran Ceriodaphnia pulchella, were studied intensively during one month characterized by deep and fast changes in the phytoplankton community: the beginning of the cyanobacteria dominance. Lake Vela, located in the Mediterranean region, is a polymictic shallow lake exhi...
Use of a new dual-antigen enzyme-linked Immunosorbent assay to detect and chara...
Marcelino, JM; Barroso, H; Goncalves, F; Silva, SM; Novo, C; Gomes, P; Camacho, R; Taveira, NA dual-antigen enzyme-linked immunosorbent assay specific for human immunodeficiency virus type 2 (HIV-2) envelope proteins, ELISA-HIV2, was developed with two new recombinant polypeptides, rpC2-C3 and rgp36, derived from the HIV-2 envelope. The diagnosti
Public attitudes towards the restoration and management of Lake Vela (Central P...
Pereira, R; Soares, AMVM; Ribeiro, R; Goncalves, FLake Vela local inhabitants' and visitors' environmental attitudes and opinions about ecological conditions of the area and future management strategies to be implemented were investigated. The facilities required and the proposal to promote tourism activities, to enhance economic development, have revealed public illiteracy about ecosystems functioning and carrying capacity. This lack of scientific knowledge w...
