Recent land use and land cover pressures on Iberian peatlands

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 and drivers of LULC in Iberian peatlands and their surrounding a...

The Tróia Peninsula: an Aeolian Sedimentological Legacy

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, and coalesced by the accumulation of sediments transported by t...

Floristic distinctiveness of the low and mid-altitude peat-rich heathlands of t...

Peat-rich heathlands, characterized and dominated by Ericaceae and Genisteae, are the southernmost outliers of the class Calluno-Ulicetea in the Mediterranean region. 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 refugia for hygrophilous plant during dry climatic phases in earth ...

Environmental evolution in the Picos de Europa (Cantabrian Mountains, SW Europe...

The Western Massif of the Picos de Europa (latitude 43 N, longitude 4e5 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, we have reconstructed the environmental events occurred in this mas...

New genetic data on Genista anglica L. versus Genista ancistrocarpa Spach (Faba...

New genetic data on Genista anglica L. versus Genista ancistrocarpa Spach (Fabaceae, Fabales) in the Iberian Peninsula and Morocco. Phylogeographic clues. 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 alread...

Long-term soil temperature dynamics in the Sierra Nevada, Spain

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 2012we havemonitored soil temperatures at different depths (2, 10, 20, 50 and 100 cm) in a solifluction landformlocated at 3...

Higro demonstrative actions for the conservation of priority habitats in northe...

An innovative methodology is being tested towards the restoration and conservation of 200 ha of mountain priority habitats: hygrophilous heather-gorse dominated shrublands [(4020) ‘*temperate Atlantic wet heaths with Erica ciliaris and Erica tetralix’] and higrophile moor matgrasses [(6230) ‘*species-rich Nardus grasslands on silicious substrates’]. These experiments comprise 35 ha in the Atlantic Biogeographic...
