Birds as indicators of HNV: Case study in Portuguese Cork Oak Montados
Rabaça, João E.; Catarino, Luísa; Pereira, Pedro; Luís, António; Godinho, CarlosMontados form a heterogeneous landscape of wooded matrix dominated by cork and/or holm oak with open areas characterized by fuzzy boundaries [3]. Montados support high biological diversity associated with low-intensity management and landscape diversity provided by a continuous gradient of land cover [4–7]. Among other features this permits the classification of montados as a High Nature Value (HNV) system. We ...
Can birds play a role as High Nature Value indicators of montado system?
Catarino, Luísa; Godinho, Carlos; Pereira, Pedro; Luís, António; Rabaça, João E.Montados form a heterogeneous landscape of wooded matrix dominated by cork and/or holm oak with open areas characterized by fuzzy boundaries.

As aves como indicadoras do estado de conservação dos montados
Catarino, Luisa; Godinho, Carlos; Pereira, Pedro; Luís, António; Rabaça, João EduardoOs montados são sistemas agro-silvo-pastoris de origem antropogénica dominados pelo sobreiro (Quercus suber) e/ou azinheira (Q. rotundifolia). São considerados sistemas de Elevado Valor Natural (High Nature Value, HNV) e estão incluídos no Anexo I da Directiva Habitats da União Europeia (92/43/CEE). No entanto, alguns montados estão ameaçados devido ao abandono da terra, sobre-pastoreio e agentes patogénicos. V...
How do hydrological and climatic conditions influence the diversity and
Carvalho, Diogo; Horta, Pedro; Raposeira, Helena; Santos, Mário; Luís, António; Cabral, JoãoWetlands are considered fundamental for the conservation of many species of birds. They are among the most threatened habitats on Earth, due to area loss through drainage and other land use changes, which lead to large-scale redistributions of birds and population declines. Although anthropogenic activities in wetlands tend to negatively affect water birds, by changing their natural habitat conditions, many spe...
A Stochastic Dynamic Methodology (StDM) to simulate the effects of fire on vege...
Santos, Pedro M. Silva; Valentim, Helena; Luís, António; Queirós, Luís; Travassos, Paulo Jorge; Cabral, JoãoWorldwide forests have been impacted by broad-scale anthropogenic pressures, such as fire and logging, leading to the disruption of the structure and functioning of these systems. The present paper examined the applicability of a holistic Stochastic Dynamic Methodology (StDM) in predicting the tendencies of passerine bird communities in maritime pine (Pinus pinaster) stands as a response to the changes induced ...
