Fire is the biggest forest hazard, especially in Mediterranean climate countries, leading to desertification and collapse (Naveh, 2007). Wildfire is among the most dramatic threats to forests (Goldammer, 2004). In many countries, it is not easy to find companies that want to insure forests stands. This can be explained by the following reasons. Firstly, in many countries, forest insurance is not mandatory; so m...
We thank M Carneiro and L Martins for technical assistance. AM-P, LP, MM and SM received fellowships from the Portuguese Foundation for Science and Technology (FCT). This work was supported by FCT (PTDC/SAU-NEU/105180/2008) and the ICVS. ; Impairment of hippocampal neurogenesis has been associated with the expression of depressive-like symptoms and some studies have suggested neurogenesis as a critical factor ...
Since adult neurogenesis became a widely accepted phenomenon, much effort has been put in trying to understand the mechanisms involved in its regulation. In addition, the pathophysiology of several neuropsychiatric disorders, such as depression, has been associated with imbalances in adult hippocampal neurogenesis. These imbalances may ultimately reflect alterations at the cell cycle level, as a common mechanis...

Brain neuroplasticity is increasingly considered to be an important component of both the pathology and treatment of depressive spectrum disorders. Recent studies shed light on the relevance of hippocampal cell genesis and cortico-limbic dendritic plasticity for the development and remission from depressive-like behavior. However, the neurobiological significance of neuroplastic phenomena in this context is sti...
O Livro Verde dos Montados apresenta diversos objectivos que se interligam: Em primeiro lugar, o Livro Verde pretende reunir e sistematizar, de uma forma simples e acessível ao público, o conhecimento produzido em Portugal pelos investigadores e técnicos de várias instituições de investigação ou de gestão que estudam o Montado. Assume-se como uma oportunidade de caracterizar o sistema tendo em conta as suas vár...

As mudanças sociais, económicas e tecnológicas que são causas e efeitos da Revolução Industrial mudaram a relação entre lazer e transportes, estando na base do nascimento do turismo contemporâneo. Pela primeira vez, na História, reunem-se de forma otimizada um conjunto de fatores que permitiu o crescimento e ampliação do fenómeno turístico. Esta dissertação procura situar este fenómeno e analisar as alterações ...
Characterization of neuronal dendritic structure in combination with the determination of specific neuronal phenotype or temporal generation is a challenging task. Here we present a novel method that combines bromodioxyuridine (BrdU) immunohistochemistry with Golgi-impregnation technique; with this simple noninvasive method, we are able to determine the tridimensional structure of dendritic arborization and spi...
