At the end of September during each period, visual surveys were used to estimate acorn numbers. Four seed traps were placed beneath the crowns of the same trees at the north, south, east, and west positions to determine acorn weight and number on a fortnightly basis during the mast seeding period (October to January). The accuracy of the visual survey was assessed by linear regression and correlation analysis. The results indicated a significant positive correlation of the two methods during all the three time periods. The resulting regression equations allowed estimation of acorn production based on visual surveys. These results suggest that the visual survey method is a simple and precise method that can be used to predict acorn production in Holm oak landscapes.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></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%">Costa, Augusta</style></author><author><style face="normal" font="default" size="100%">Madeira, Manuel</style></author><author><style face="normal" font="default" size="100%">Plieninger, Tobias</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Cork oak woodlands patchiness: A signature of imminent deforestation?</style></title><secondary-title><style face="normal" font="default" size="100%">Applied Geography</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Forest degradation</style></keyword><keyword><style  face="normal" font="default" size="100%">Fractional canopy cover</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean landscape</style></keyword><keyword><style  face="normal" font="default" size="100%">Patch size–frequency distribution</style></keyword><keyword><style  face="normal" font="default" size="100%">Power-law function</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2014///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.sciencedirect.com/science/article/pii/S0143622814001623</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">54</style></volume><pages><style face="normal" font="default" size="100%">18 - 26</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The cork oak (Quercus suber L.) woodlands of the agroforestry landscapes of Southwestern Iberia are undergoing drastic change due to severe natural and anthropogenic disturbances. These may eventually result in woodland loss or deforestation, the final step of an ongoing process of woodland degradation. Monitoring changes in the spatial patterns of woodlands – especially fractional canopy cover of woodlands and/or their patchiness in the landscape mosaic – potentially enables forecasting of loss and responding to it at an early stage. We examine the degradation process in two cork oak woodlands, resulting from distinct disturbances, wildfire and oak mortality, aimed at evaluating the changes, trends and deviations of the spatial attributes of these woodlands as they move from an initial (less disturbed ecosystem) to a final state (more disturbed ecosystem). While undergoing disturbances, both woodlands exhibited similar trends of decreasing fractional canopy cover and decreasing number of larger patches. Patchiness rather than fractional canopy cover seems, however, to be potentially more useful as a signature of imminent oak woodlands deforestation, given that its contrast before and after disturbance was much higher. The structural dynamics of oak woodlands is a crucial but neglected issue that needs greater attention from policy forums working toward their conservation and restoration as well as from stakeholders and society as a whole.</style></abstract></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%">Espírito-Santo, C.</style></author><author><style face="normal" font="default" size="100%">ROSALINO, LUIS M.</style></author><author><style face="normal" font="default" size="100%">Santos-Reis, Margarida</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Factors affecting the placement of common genet latrine sites in a Mediterranean landscape in Portugal</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of mammalogy</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">common genets</style></keyword><keyword><style  face="normal" font="default" size="100%">genetta genetta</style></keyword><keyword><style  face="normal" font="default" size="100%">latrines</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean landscape</style></keyword><keyword><style  face="normal" font="default" size="100%">Portugal</style></keyword><keyword><style  face="normal" font="default" size="100%">scent marking</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.asmjournals.org/doi/abs/10.1644/05-MAMM-A-343R3.1</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">88</style></volume><pages><style face="normal" font="default" size="100%">201 - 207</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In addition to the role of latrine sites as areas for deposition of feces, they may play roles in territoriality, sexual attraction, warning and defense behaviors, and regulation of physiological functions. Several carnivores, such as the common genet (Genetta genetta) use latrines as stations for scent communication. We describe the factors influencing the placement and use of latrine sites by a Mediterranean population of common genets inhabiting cork oak woodlands in southwestern Portugal. Using logistical regression analysis, we found a higher probability of finding latrines in areas with high understory height and diversity of landscape units, low human disturbance and accessibility, and proximity to potential refuges and other latrines. An exploratory univariate analysis showed that latrines were located primarily in conspicuously high features within the landscape such as in old-growth cork oak trees. Their use was associated with low human disturbance, inaccessibility, and high understory cover. Our results suggest that forest managers should preserve some old trees in oak woodlands, because these trees have a fundamental role in scent communication among genets (latrines), as well as serve as resting sites.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record></records></xml>
