Cultivated soils (CS) with insufficient management, 5 year abandoned soils covered with meadow (A5), 25 year abandoned soils covered with dense scrubs (A25), 50 year abandoned soils covered with cork trees (A50) and soils in a 50 year pine reforested area (P50) were studied over a period of 6 months (May-October 1999). The soils were classified as Lithic Xerorthents. Both the differences in soil properties and response to rainfall events were mainly attributed to the different vegetation types and stages in land management. Principal components analysis (PCA) was performed on the results, by running the overall data determined after five rainfall events. The factors extracted by PCA of the samples by variables matrix represented the response of the environments to different rainfall intensities as a function of management or natural evolution after abandonment. CS environments showed the highest runoff and sediment yield as well as the highest amount of dissolved organic carbon (DOC) and nitrogen in runoff water. The sequence of abandonment (A5, A25 and A50) showed approximately the same runoff production, whereas eroded sediments (ES) and DOC were inversely correlated. Organic carbon in the ES and DOC in runoff water always increased with the period of abandonment, which accounted for consistent nutrient depletion. Nevertheless, the A50 environment (dominated by Quercus suber) showed the best soil properties, whilst the A25 environment with dense cover of Cistus monspeliensis and Calicotome espinosa seemed to cause a worsening effect on the soil's physical and chemical properties. This is probably because these environments are more severely damaged by wild fire occurrence. In terms of sediment yield, the P50 environment followed CS environment, indicating that reforestation followed by insufficient forest management may negatively affect both soil properties and response to the erosive action of rainfall.</style></abstract><accession-num><style face="normal" font="default" size="100%">12798105</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pardini, Giovanni</style></author><author><style face="normal" font="default" size="100%">Gispert, Maria</style></author><author><style face="normal" font="default" size="100%">Dunjó, Gemma</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Runoff erosion and nutrient depletion in five Mediterranean soils of NE Spain under different land use.</style></title><secondary-title><style face="normal" font="default" size="100%">The Science of the total environment</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Abandonment</style></keyword><keyword><style  face="normal" font="default" size="100%">erosion</style></keyword><keyword><style  face="normal" font="default" size="100%">land management</style></keyword><keyword><style  face="normal" font="default" size="100%">nutrient availability</style></keyword><keyword><style  face="normal" font="default" size="100%">Nutrient losses</style></keyword><keyword><style  face="normal" font="default" size="100%">runoff</style></keyword><keyword><style  face="normal" font="default" size="100%">Sediment yield</style></keyword><keyword><style  face="normal" font="default" size="100%">soil properties</style></keyword><keyword><style  face="normal" font="default" size="100%">structure</style></keyword><keyword><style  face="normal" font="default" size="100%">Water retention</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2003</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2003///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/12798105</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">309</style></volume><pages><style face="normal" font="default" size="100%">213 - 224</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We investigated the influence of agricultural management and various plant covers related to the period of abandonment on soil properties, erosion and nutrient depletion in a typical Mediterranean area with sandy loam shallow soils.

This paper presents a comparison of two alternative methods to describe and map vegetation: on the basis of plant species and growth forms, respectively. A stratified random sampling was taken from spontaneous vegetation in 1989 on the volcanic island of Pantelleria (near Sicily, Italy). Cartographic and other comparisons of the results from classification and ordination analysis suggest that the major differences were associated with differences in the time scale of the underlying processes. Species results (leading to floristic vegetation units) were representative of longer-term processes, growth-form results (leading to structural vegetation units) with shorter-term processes. Further implications of these results are discussed.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">DE SIMÓN NAVARRETE, E</style></author><author><style face="normal" font="default" size="100%">Investigaci, Nnavarrete Centro D E</style></author><author><style face="normal" font="default" size="100%">Apartado, Agraria D E Granada</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Restauración del bosque mediterráneo: aplicación de modelos de restauración a los encinares.</style></title><secondary-title><style face="normal" font="default" size="100%">II Congreso Forestal Español</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Evolution</style></keyword><keyword><style  face="normal" font="default" size="100%">hydrological process</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean forest</style></keyword><keyword><style  face="normal" font="default" size="100%">Restoration</style></keyword><keyword><style  face="normal" font="default" size="100%">structure</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><pub-location><style face="normal" font="default" size="100%">Pamplona</style></pub-location><pages><style face="normal" font="default" size="100%">271-276</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The activities in order to restore the mediterraneam forests have been constitued by the restoration of the structures and natural vegetation communities in order to preserve the water and soil in the drainage basins.
