  • Rock coast inheritance : an example from Galicia, northwestern Spain
  • C 14 dating ; Coastal environment ; Galicia ; Inherited features ; Interglacial ; Marine quaternary ; Model ; Sea level ; Shore platform ; Spain
  • A shore platform on the western coast of Galicia in northwestern Spain has been inherited from interglacial stages when sea level was similar to today. The wide, gently sloping intertidal platform is backed in places by supratidal rock ledges

  • The evolution and significance of soil-vegetation patterns following land abandonment and fire in Spain
  • Almería ; Ecosystem ; Gerona ; Infiltration ; Mediterranean area ; Rainfall simulation ; Rill wash ; Soil ; Soil degradation ; Soil erosion ; Spain ; Vegetation
  • Examples are presented from 2 locations in SE and NE Spain where patterned or banded vegetation are found on semi-natural and abandoned land or where vegetation is recovering from wildfire. In both cases patterns are being investigated as process
