Glacial–interglacial cycles in the south-central and southeastern Pyrenees sinc...
Turu, Valenti; Peña-Monné, Jose Luís; Cunha, Pedro P.; Jalut, Guy; Buylaert, Jan-Pieter; Murray, Andrew S.; Bridgland, David R.; Faurschou-Knudsen, MadsThis study uses luminescence and 14C accelerator mass spectrometry procedures to date relevant glaciofluvial and glacial deposits from the south-central and southeastern Pyrenees (Andorra–France–Spain). We distinguish two types of end-moraine complexes: (1) those in which at least a far-flung moraine exists beyond a frequently nested end-moraine complex (the most common) and (2) those in which a closenested end...
Aurochs roamed along the coast of SW Spain (Iberia) during Late Pleistocene
Neto de Carvalho, Carlos; Muñiz, Fernando; Cáceres, Luis M.; Belaústegui, Zain; Rodríguez‑Vidal, Joaquín; Belo, João; Moreira, Noel; Cachão, MárioIn the Iberian Peninsula the fossil record of artiodactyls spans over 53 million years. During the Pleistocene, wild cattle species such as Bison and especially Bos became common. In Late Pleistocene, the aurochs (Bos primigenius) was widespread and the only bovine living along the large river valleys of southern Iberia. Although commonly found in fossil sites and especially in cave bone assemblages, the trace ...
The endorheic-exorheic transition and later stage of fluvial incision in a wet ...
Freitas, Marcelo Motta de; Paixão, Rodrigo W.; Salgado, André A.R.; Silva, Luiz G. Eirado; Cunha, Pedro P.; Gomes, António AlbertoPresent-day endorheic drainage systems are rare in tropical humid regions and/or close to the coast. During the late Cenozoic, under a humid tropical climate, the Paraíba do Sul River basin (SE Brazil) has developed along the South America passive margin. This basin currently drains into the South Atlantic Ocean, but it preserves landforms that are indicative of previous endorheic paleodrainage. This study exam...
Ecosystem services as a resilience descriptor in habitat risk assessment using ...
Vera, Claudia; Marques, João Carlos; Cunha, Pedro P.; Teixeira, ZaraVulnerability of coastal ecosystems has been increasing as a result of human perturbations that compromise the ability to provide multiple ecosystem services. Vulnerability is a function of exposure to stressors and of sensitivity to impact and resilience; it has been suggested as a proxy of a habitat's ability to deliver ecosystem services. Different approaches have been proposed; some assume that vulnerabilit...
Identifying ecosystem services research hotspots to illustrate the importance o...
Caro, Claudia; Cunha, Pedro P.; Marques, João Carlos; Teixeira, ZaraThe mismatch between the conceptual understanding of the Ecosystem Services (ES) in science, and their practical application, remains. Among the many issues under discussion is the link between knowledge and implementation. Base knowledge built over cases studies exist, but their usefulness for site-specific management purposes is limited. The goal of this work is to illustrate how gap analysis at the local lev...
Active landscapes of Iberia
Pedro Galve, Jorge; Pérez-Peña, José Vicente; Azañón, José Miguel; Pereira, D. I.; Cunha, Pedro P.; Pereira, Paulo; Ortuño, María; Viaplana-Muzas, M.The recent geodynamic evolution of Iberia is recorded in its topography. Geomorphic markers and their dating; morphometric indices estimated through cutting-edge DEM analysis techniques; and the link of all this data with results of geophysical studies allow discussing why Iberia displays the highest average elevation in Europe and shows a particular topography with such diversity of landscapes. For example, th...
A new Hauterivian palynoflora from the Vale Cortiço site (central Portugal), an...
Mendes, Mário Miguel; Polette, France; Cunha, Pedro P.; Dinis, Pedro; Batten, David J.Palynofloral assemblages are an invaluable source of information about the interactions between fossil plants and their environments. Here we describe a new Early Cretaceous palynoflora from the Lusitanian Basin in the Estremadura region of central western Portugal. A palynological assemblage of 28 genera and 40 species was extracted from 14 samples collected in the Vale Cortiço clay pit complex near the small ...
The Lowermost Tejo River Terrace at Foz do Enxarrique, Portugal: A Palaeoenviro...
Cunha, Pedro P.; Martins, António; Buylaert, Jan-Pieter; Murray, Andrew S.; Gouveia, Maria P.; Font, Eric; Pereira, Telmo; Figueiredo, SilvérioReconstruction of Pleistocene environments and processes in the sensitive geographical location of westernmost Iberia, facing the North Atlantic Ocean, is crucial for understanding impacts on early human communities. We provide a characterization of the lowest terrace (T6) of the Lower Tejo River, at Vila Velha de Ródão (eastern central Portugal). This terrace comprises a lower gravel bed and an upper division ...
The long-term evolution of the Douro River as evidenced by strath terrace stair...
Cunha, Pedro P.; Martins, António A.; Gomes, Alberto; Cabral, João; Lopes, Fernando C.; Pereira, D. I.; Vicente, Gerardo de; Buylaert, Jan-PieterIn western Iberia, mechanisms that explain the transition from endorheic to exorheic continental-scale drainage reorganisation are foreland basin overspill, headwards erosion and capture by an Atlantic river, or a combination of both. To explore these controls we have investigated the Portuguese sector of the Douro River, the site of drainage re-organsation. The Douro River routes downstream through weak sedime...

Cunha, Pedro P.; Martins, António A.; Gomes, Alberto; Stokes, Martin; Cabral, João; Lopes, Fernando C.; Pereira, D. I.; Vicente, Gerardo deIn western Iberia, mechanisms that can explain the transition from endorheic to exorheic continental-scale drainage reorganization are foreland basin overspill, headwards erosion and capture by an Atlantic river, or a combination of both. To explore these, we have investigated the Portuguese sector of the Douro River, the locus of drainage reorganization. The Douro River is routed downstream through the weak se...
