Recent efforts have compiled distribution data on Iberian Peninsula peatlands, however, the criteria used to characterise these ecosystems have often been derived from regions where peatlands are more extensive and typically occur under wetter climatic conditions. As a result, many peat-accumulating wetlands in this region were overlooked. Identify...

Ecosystems with a naturally accumulated peat layer at the surface and wetlands with or without a peat layer dominated by a vegetation that may produce peat (hereafter 'peatlands' for simplicity) are critical assets in global change due to their large carbon content storage capacity and essential ecosystem services. A Global Peatland Assessment was...

Iberian peatlands have been severely affected by land use and land cover (LULC) changes. Despite these pressures , some peatlands persist in the region, although their susceptibility to LULC change remains poorly understood. This study presents the most detailed and extensive distribution data for Iberian peatlands to date and analyzes the dynamics...

Peat-rich heathlands, characterized and dominated by Ericaceae and Genisteae, are the southernmost outliers of the class Calluno-Ulicetea in the Mediterranean area. They occur in small and isolated patches along the Atlantic façade of the SW Europe on acidic soils with peat formation and on hydromorphic podzols. Such sites could have acted as refug...

The integration of studies from fields, such as geomorphology, palynology, history, archaeology and phytogeography, enables assessing the genesis and evolution of the most prominent Portuguese sand spit—the Tróia Peninsula. Data suggests that the spit has formed from Grimaldian dunes converted into barrier islands during the Holocene transgression,...

English. The genetic analysis through the nuclear ribosomal DNA of some Iberian and NW Morocco populations of Genista ancistrocarpa Spach and G. anglica L. has validated the separation of these two sister taxa as two distinct genetic entities, strengthening the already described morphological differentiation. The studied populations neatly show the...

Nightlife economic activity has emerged as a key strategy in the regeneration of historical quarters. The case of the Bairro Alto district (Lisbon) exhibits a more gradual and distinct development caused by the marginal and transgressive practices of nightlife visitors, who have resisted its gentrification for decades. Some areas in the Bairro Alto...

The Western Massif of the Picos de Europa (43°N – 4‐5°W) includes some of the highest peaks in the Cantabrian Mountains. This massif was heavily glaciated during the Last Glaciation, though the post‐glacial environmental evolution is still poorly understood. Using a geomorphological and sedimentological approach, we have reconstructed the environme...

The Western Massif of the Picos de Europa (latitude 43° N, longitude 4-5° W) includes some of the highest peaks in the Cantabrian Mountains. This massif was heavily glaciated during the Last Glaciation, though the post-glacial environmental evolution is still poorly understood. Using a complementary geomorphological and sedimentological approach, w...

The Western Massif of Picos de Europa includes some of the highest peaks of the Cantabrian Mountains. However, the environmental evolution in this massif since the Last Glaciation is still poorly understood. This research provides a new geochronological approach to the sequence of environmental events occurred here since the maximum expansion of gl...

Soil temperatures play a key role on the dynamics of geomorphological processes in periglacial environments. However, little is known about soil thermal dynamics in periglacial environments of semiarid mid-latitude mountains, where seasonal frost is dominant. From September 2006 to August 2012 we have monitored soil temperatures at different depths...

We propose a novel alliance within Calluno-Ulicetea class: Ulici lusitanici-Genistion ancistrocarpae. This new syntaxon gathers the vegetation communities from the lower and mid altitude ranges of the western Iberian Peninsula and northwestern Morocco, comprising mainly the thermomediterranean and mesomediterranean areas but reaching also thermotem...

Abstract This research analyzes the deglaciation of the Western Massif of Picos de Europa and the postglacial environmental evolution based on field observations, geomorphological mapping, sediment cores and radiocarbon datings. Four main glacial stages have been identified: (1) maximum advance corresponding to the Last Glaciation, (2) internal pha...

The genetic analysis through the nuclear ribosomal DNA of some Iberian and NW Morocco populations of Genista ancistrocarpa Spach and G. anglica L. has validated the separation of these two sister taxa as two distinct genetic entities, strengthening the already described morphological differentiation. The studied populations neatly show the G. ancis...

Unlocking the palaeoenvironmental context, in which present peaty sols in former cold regions of Western Europe, may contribute to the understanding of the actual distribution of three acid-soil vascular plants. Likewise can the role played by similar soil and water conditions (due to other context) be the key to explain their expansion further Sou...

In this paper we propose a syntaxonomic scheme, according to the Code of Phytosociological Nomenclature for the vegetation of Portugal: continental and the Azores and Madeira archipelagos. The scheme encompasses 827 associations (4 communities), 245 alliances, 116 orders, and 64 vegetation classes. The 58 suballiances, 2 suborders and 4 subclasses,...

RESUMO Nas últimas décadas o fenómeno da inovação tem sido um forte modelador do território, traduzindo diferentes dinâmicas. Expõe-se um projeto de seminário da licenciatura em Geografia, em que foram analisados e discutidos os modelos de inovação e o seu impato, propondo o recurso a um caso de estudo: o tecnopolo de Adlershof, em Berlim. Visou-se...
