Disposal of dredged sediments in tropical soils: ecotoxicological effects on ea...
Cesar, Ricardo; Natal-da-Luz, Tiago; Sousa, José Paulo; Colonese, Juan; Bidonne, Edison; Castilhos, Zuleica; Egler, Silvia; Polivanov, HelenaThe upper limit concentrations of metals established by international legislations for dredged sediment disposal and soil quality do not take into consideration the properties of tropical soils (generally submitted to more intense weathering processes) on metal availability and ecotoxicity. Aiming to perform an evaluation on the suitability of these threshold values in tropical regions, the ecotoxicity of metal...
Contributions of Marine Cluster for Regional Sustainability: Economic Prospecti...
Paramio, Luz; Tiago, Maria Teresa Borges; Tiago, Flávio Borges; Vieira, José CabralThe project SEAValue proposes to develop a first integrate approach to valuation of the Sea of Azores from economic view analyses.The project aims the estimation of the contribution of the sea, namely, maritime sector and marine ecosystem services, and their benefits for the sustainable development of the Autonomous Region of Azores through a responsive and effective decision support process.Nowadays, the world...
Integrated evaluation of the ecotoxicological risk of using sewage sludges in a...
Luz, Tiago Manuel Ferreira Natal daA análise química exigida por lei para regulamentar o uso de lamas residuais na agricultura é claramente insuficiente para avaliar o risco potencial da utilização deste tipo de resíduos em solo, dado que nem o efeito de contaminantes não incluídos na análise química nem os efeitos que ocorrem como resultado de interacções entre compostos químicos são tidos em linha de conta. Por essa razão a necessidade em comp...
Tolerance of genetically characterized Folsomia candida strains to phenmedipha...
Diogo, João; Natal-da-Luz, Tiago; Sousa, José; Vogt, Christian; Nowak, CarstenAbstract Background, Aims, and Scope The springtail Folsomia candida is a commonly used model species in ecotoxicological soil testing. The species reproduces parthenogenetically and, thus, laboratories use different clonal lineages. In this study, we investigated if genetic divergence between F. candida strains impacts the reaction to chemical stress and may thus affect the outcome of toxicity tests. Metho...
Effects of land-use on Collembola diversity patterns in a Mediterranean landscape
Sousa, José Paulo; Gama, Maria Manuela da; Pinto, Cristina; Keating, António; Calhôa, Filipa; Lemos, Marco; Castro, Catarina; Luz, Tiago; Leitão, PedroCollembola communities were sampled along a gradient of soil-use intensification in a typical Mediterranen landscape dominated by cork-oak. This gradient ranged from a land-use unit (LUU1) dominated by closed oak forest with minimum intervention to an unit entirely composed of a monoculture crop submitted to frequent anthropogenic disturbances (LUU6), passing through LUUs with managed woodland (LLU2) or dominat...
