  • Geomorphic agents versus vegetation spreading as causes of badland occurrence in a Mediterranean subhumid mountainous area
  • Badlands in changing environments. Special issue

  • Badland ; Freezing ; Mediterranean area ; Mountain ; Pyrénées ; Slope dynamics ; Spain ; Vegetation ; Weathering
  • The aim of this study is to discuss the mechanisms that determine the occurrence of badland forms in a subhumid mountain area in the Vallcebre area, southeastern Pyrenees, that has been subjected to detailed studies on physical weathering
  • and vegetation dynamics. Special attention is paid to the amounts of energy available for the main geomorphic agents (rainfall, freezing, clay shrinking) as well as to the explication of the preferred occurence of badland surfaces in north facing aspects.

  • Soil seed bank and seedling dynamics in badlands of the Upper Llobregat basin (Pyrenees)
  • Badlands in changing environments. Special issue

  • and seedling phases in the badland areas of the Upper Llobregat basin. The AA. sought to test the hypothesis that seed availability and seedling recruitment was not enough to guarantee colonization of these areas.

  • The aim of this study is to analyze a recent deposition-erosion alternation within a badland area in semiarid South-East Spain. Given the small size of the drainage areas involved, this alternation can be analyzed in terms of hillslope
