Temporal changes in macrofauna as response indicator to potential human pressur...
Bessa, Filipa; Gonçalves, Sílvia C.; Franco, João N.; André, José N.; Cunha, Pedro P.; Marques, J. C.Sandy beaches are natural dynamic ecosystems, which are becoming worldwide increasingly disturbed by intensive human direct use, coastal development and erosive evolution. In this study, we have examined whether ten years of potential increased human pressures have resulted in significant changes in the macrofaunal assemblages’ structure and composition of two mesotidal sandy beaches (Cabedelo – urban beach, an...
Evolução geológica de Portugal continental durante o Cenozóico - sedimentação a...
Cunha, Pedro P.; Pais, João; Legoinha, P.6º Simposio sobre el Margen Ibérico Atlántico MIA09 ; In Portugal mainland Cenozoic sedimentation occurred largely but allocated to several basins. Even in the same basin, the sedimentary record shows significant lateral changes in facies and thickness. However, the main sedimentary ruptures and overall lithologic characteristics of the infilling stages are quite similar in the several basins, reflecting the g...
Dating the Tejo river lower terraces in the Ródão area (Portugal) to assess the...
Cunha, Pedro P.; Martins, António A.; Huot, Sebastien; Murray, Andrew; Raposo, LuísThe Tejo river is one of the major drainages in Iberian Peninsula; it is a long-lived system (ca. 3.4 Ma) and provides an archive of long-term landscape development and environmental change controlled by tectonics, climate and eustasy. The most upstream Portuguese reach of the Tejo river, ~ 200 km from the Atlantic coast, shows evidence for five fluvial terraces (T1 to T5) with elevations reaching more than 120...
Definition of the Portuguese frameworks with international relevance as an inpu...
Brilha, J.; Cunha, Pedro P.; Azerêdo, A.; Barriga, F. J. A. S.; Azeredo, A.; Cachão, M.; Couto, H.; Andrade, C.; Crispim, J. A.; Dantas, P.This work constitutes the first contribution for the systematisation of the geological heritage knowledge in Portugal, following the international recomendations for the characterisation of geological heritage (IUGS, ProGEO). The application of the ProGEO methodology has resulted on the creation of fourteen frameworks with international relevance, established by consensus among the Portuguese geological communi...
