The Portuguese montado is one of the most significant HNV systems in southern Europe. However, considering the great complexity characterizing these systems both in land management and in landscape structure, a specific context-oriented methodology to assess which montado areas are likely to be classified as HNV farmland is needed. In this sense, the aim of this study is to explore a methodological approach which makes it possible to assess land management pressures through land cover information on these complex silvo-pastoral systems. The proposed methodology was tested through a local case study in a montado area in southern Portugal, assessing the relation between management practices and a vegetation cover index. Results show that in similar montado areas different land management strategies varying in stocking density, but also in type of grazing animals and shrub control practices, configure different vegetation cycles. These results indicate there is a way to develop a straightforward methodology to assess the HNV value of Mediterranean silvo-pastoral systems based on land cover indicators. These would make it possible to assess the HNV of montado areas with direct and objective information and independent of farmer's surveys or other farm-based data.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: OSTER VOLDGADE 10, COPENHAGEN K, DK 1350, DENMARK&lt;br/&gt;publisher: ROYAL DANISH GEOGRAPHICAL SOC</style></notes></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%">Antunes, Carla Rolo</style></author><author><style face="normal" font="default" size="100%">Coutinho, Miguel Azevedo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">O factor de coberto vegetal, para árvores e Arbustos, em modelos de erosão hídrica</style></title><secondary-title><style face="normal" font="default" size="100%">Revista de Ciências Agrárias</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Dripping</style></keyword><keyword><style  face="normal" font="default" size="100%">erosion models</style></keyword><keyword><style  face="normal" font="default" size="100%">interception</style></keyword><keyword><style  face="normal" font="default" size="100%">soil conservation</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation cover</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">34</style></volume><pages><style face="normal" font="default" size="100%">234 - 242</style></pages><isbn><style face="normal" font="default" size="100%">0871-018X UL - http://www.scielo.gpeari.mctes.pt/scielo.php?script=sci_arttext&amp;pid=S0871-018X2011000200021&amp;nrm=iso</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The main objective of this work consists on the analyzes of tree and bush canopies behavior, in terms of the rainfall interception process, namely, leave retention, and dripping, and the establishment of a erosion model component to include in to quantify the cover factor (C) of the Revised Universal Soil Loss Equation (RUSLE) for mixed land covered systems with arable crops, in association with trees and bushes. In the experimental work a rainfall simulator was used and the characteristic values for the diameter of the dripping drops and retention of the leaves from characteristic species of the more common mixed land-use systems in Southern of Portugal, particularly with Cork oak (Quercus suber L.), Holm or evergreen oak (Quercus ilex L. ssp. rotundifolia Lam) and Kermes or wild oak (Quercus coccifera L.), were obtained. From the obtained results the kinetic energy for different drop heights was estimated and, consequently, correction factors were calculated to be applied to the factor C.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: scielopt</style></notes></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%">Aponte, Cristina</style></author><author><style face="normal" font="default" size="100%">Marañón, Teodoro</style></author><author><style face="normal" font="default" size="100%">García, Luis V.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Microbial C, N and P in soils of Mediterranean oak forests: influence of season, canopy cover and soil depth</style></title><secondary-title><style face="normal" font="default" size="100%">Biogeochemistry</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">á</style></keyword><keyword><style  face="normal" font="default" size="100%">dynamics á</style></keyword><keyword><style  face="normal" font="default" size="100%">Microbial biomass</style></keyword><keyword><style  face="normal" font="default" size="100%">microbial biomass á nitrogen</style></keyword><keyword><style  face="normal" font="default" size="100%">nitrogen</style></keyword><keyword><style  face="normal" font="default" size="100%">Nutrient immobilization</style></keyword><keyword><style  face="normal" font="default" size="100%">nutrient immobilization á phosphorus</style></keyword><keyword><style  face="normal" font="default" size="100%">phosphorus</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant–soil interactions</style></keyword><keyword><style  face="normal" font="default" size="100%">seasonal dynamics</style></keyword><keyword><style  face="normal" font="default" size="100%">soil interactions á seasonal</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation cover</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s10533-010-9418-5http://link.springer.com/10.1007/s10533-010-9418-5</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">101</style></volume><pages><style face="normal" font="default" size="100%">77 - 92</style></pages><isbn><style face="normal" font="default" size="100%">1053301094185</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In Mediterranean ecosystems the effect of aboveground and belowground environmental factors on soil microbial biomass and nutrient immobilization-release cycles may be conditioned by the distinctive seasonal pattern of the Mediterraneantype climates. We studied the effects of season, canopy cover and soil depth on microbial C, N and P in soils of two Mediterranean forests using the fumigation-extraction procedure. Average microbial values recorded were 820 lg C g -1 , 115 lg N g -1 and 19 lg P g -1 , which accounted for 2.7, 4.7 and 8.8% of the total pools in the surface soil, respectively. Microbial N and P pools were about 10 times higher than the inorganic N and P fractions available for plants. Microbial C values differed between forest sites but in each site they were similar across seasons. Both microbial and inorganic N and P showed maximum values in spring and minimum values in summer, which were positively correlated with soil moisture. Signiﬁcant differences in soil microbial properties among canopy cover types were observed in the surface soil but only under favourable environmental conditions (spring) and not during summer. Soil depth affected microbial contents which decreased twofold from surface to subsurface soil. Microbial nutrient ratios (C/N, C/P and N/P) varied with seasons and soil depth. Soil moisture regime, which was intimately related to seasonality, emerged as a potential key factor for microbial biomass growth in the studied forests. Our research shows that under a Mediterranean-type climate the interaction among season, vegetation type and structure and soil properties affect microbial nutrient immobilization and thus could inﬂuence the biogeochemical cycles of C, N and P in Mediterranean forest ecosystems.</style></abstract><issue><style face="normal" font="default" size="100%">1-3</style></issue></record></records></xml>
